ABSTRACT

Students make many choice over a long period, andchoose a career through a complicated process. This process includesformal irstructioa in mathematics and science, and the opportunityfor informal education in museums, science centers, and recreationalprograms. The influence of family, teachers, peers, and theelectronic media can rake an enormous difference. This memorandumanalyzes these influences. Because education is all one system,policymakers interested in nuturing scientists and engineers mustaddress the educational environment as a totality; changing only onepart of the system will not yield the desired result. Discussionscovered in this report include how the science and engineering talentpool is shaped; the formal educational process; teachers; teachingmethods; informal education; and how to improve science andmathematics education. Appendices include a list of the majornational databases on K-12 science and mathematics education andstudents; science and mathematics education in the USSR, GreatBritain, and Japan; a survey of the National Association for Researchin Science Teaching; and a list of the reports of contractorsprepared for this document.

Foreword

Choice, chance, opportunity, and environment are all factors that determine whetheror not a child will grow up to be a scientist or engineer. Though comprising only 4percent of our work force, scientists and engineers are critical to our Nation's continuedstrength and vitality. As a Nation, we are concerned about maintaining an adequatesupply of people with the ability to enter these fields, and the desire to do so.

In response to a request from the House Committee on Science and Technology,this technical memorandum analyzes recruitment into and retention in the science andengineering pipeline. Elementary and Secondary Education for Science and Engineer-ing supplements and extends OTA's June 1988 report, Educating Scientists and Engi-neers: Grade School to Grad School.

Students make many choices over a long period, and choose a career through acomplicated process. This process includes formal instruction in mathematics and sci-ence, and the opportunity for informal education in museums, science centers, and recrea-tional programs. The influence of family, teachers, peers, and the electronic media canmake an enormous difference. This memorandum analyzes these influences. Becauseeducation is "all one system," policymakers interested in nurturing scientists aad engi-neers must address the educational environment as a totality; changing only one partof the system will not yield the desired result.

The Federal Government plays a key role in sustaining educational excellence inelementary and secondary education, providing effective research, and encouragingchange. This memorandum identifies pressure points in the system and strengthens theanalytical basis for policy.

Preface

This technical memorandum augments OTA'sreport, Educating Scientists and Engineers: GradeSchool to Grad School,' focusing on the factorsthat prompt students to plan science and engineer-ing careers during elementary and secondary edu-cation, and the early stages of higher education.While examining the problems and opportunitiesfor students, OTA offers no comprehensive as-sessment of the system of American public edu-cation. Rather, it takes this system as the contextfor understanding, and proposes changes in pre-professional education.

Most educators and parents regard science andmathematics as basic skills for every high schoolgraduate. By upgrading mathematics and scienceliteracymaking more graduates proficient inthese subjectsmost believe that the pool of po-tential scientists and engineers would be larger andmore diverse. At the same time, broader appli-cation of basic skills in mathematics and sciencewould benefit the entire U.S. work force. Perhapsthen concern for the future supply of scientists andengineers, as one professional category of work-ers among many, would recede as an urgent na-tional issue.

As this is not the case, the problem of educat-ing scientists and engineers is unabating; the scru-tiny of schools, teaching standards, and studentoutcohies is intensifying; and calls for improvedFederal action grow louder. As Paul Gray, Presi-dent of the Massachusetts Institute of Technol-ogy said: "Americans must come to understandthat engineering and scie ice are not esoteric questsby an elite few, but are, instead, humanistic ad-ventures inspired by native human curiosity aboutthe world and desire to make it better."'

OTA takes a long view of the science ,nd engi-neering pipeline and does not dwell solely on thosewhose scientific talents are manifested at earlyages. The science a id ergineering pipeline includesall students during elementary and much of sec-

ondary schooling. But as students move towardundergraduate and graduate school, smaller pro-portions form the talent pool. Students makechoices o- e- long periods and are influenced bymany factors; this complicates analysis and makesit difficult to ascertain specific influences or theirdegree of impact on careers.

Although most students' career intentions areill-formed, some decide to pursue science andengineering early in life and stick with that deci-sion. This "hard-core group" is joined by manycompanions later on. Chapter 1, Shaping the Sci-ence and Engineering Talent Pool, concerns boththe hard core and those whose plans are moremalleable. As this latter group is uncertain aboutwhat major to choose, it may be more suscepti-ble to parents' wishes, financial incentives, andthe attractiveness of science and engineeringcareers. Whether si-idents respond to a profes-sional "calling" or hear the call of the marketplace,they are lured to some careers and away fromothersand schools are agents of this allure.

For many children, the content of mathematicsand science classes and the way these subjects aretaught critically affect their interest and later par-ticipation in science and engineering. Chapter 2,Formal Mathematics and Science Education, re-views concern over the pace and sequence of theAmerican mathematics and science curriculum,the alleged dullness of many science textbooks,and the extent to which greater use of educationaltechnology, such as computers, could improve theteaching of mathematics and science.

This responsibility falls primarily on the teach-ing profession, together with school districts andteacher education institutions. Chapter 3,Teachers and Teaching, discusses predicted short-ages of mathematics and science teachers, andconcern about the poor quality of teacher train-ing and inservice programs in all subjects. Thequality of teaching, in the long run, depends onthe effectiveness of teachers, the adequacy of theirnumbers, and the extent to which they are sup-ported by principals, curriculum specialists, tech-nology and materials, and the wider community.Teachers of mathematics and science need to beeducated to high professional standards and, like

2

members of other professions, they also need toupdate their skills periodically.

At the same time, research on teaching of math-ematics and science suggests that some techniques,not widely used in American schools, can improveachievement, transmit more realistic pictures ofthe enterprise of science and mathematics, andbroaden participation in science and engineeringby women and minorities. Chapter 4, ThinkingAbout Science Learning, asks: How can more stu-dents be successful in science and mathematics?Does science and mathematics education searchfor and select a particular type of student, onewith a certain learning style? This chapter de-scribes other efforts to correct misconceptions(held both by students and teachers), spur creativ-ity, develop "higher order thinking skills," andto place more students on pathways to learningscience and mathematics.

The out-of-school environment offers oppor-tunities to raise students' interest in and aware-ness of science and mathematics. Chapter 5,Learning Outside of School, highlights "informaleducation" activities that draw strength from thelocal communitychurches, businesses, volun-tary organizations, and their leaders. All are po-tential agents of change. All are potential filtersof the images of science and scientistsoften neg-ative, almost always intimidatingtransmitted bytelevision and other media. Science centers andmuseums, for example, On awaken or reinforceinterest, without raising the spectre of failure for

those who lack confidence in their abilities. In-tervention programs, aimed especially at enrich-ing the mathematics and science preparation ofwomen, Blacks, Hispanics, and other minorities,can rebuild confidence and interest, tapping poolsof talent that are now underdeveloped.

The problems that face mathematics and sci-ence education in the schools are complicated andinterrelated. Chapter 6, Improving School Math-ematics and Science Education, proposes a sys-temic approach to these problems, requiring aconstellation of solutions. Reforms, however, tendto be incremental. Change in any one aspect ofmathematics and science teaching, such as course-taking, tracking, testing, and the use of labora-tories and technology, is constrained by otheraspects of the system, such as teacher training andremuneration, curriculum decisions, communityconcerns and opinions, and the influences ofhigher education.

Finally, this report illuminates the gulf betweenknowing and doing, between recognizing "whatworks" and replicating it. On many educationalissues, experts are groping to specify the bound-aries of their ignorance; on others, there are mas-sive data on causes and effects, but little wisdomon how to implement change. It is this latter needthat invites Federal initiative, whether "seeding"a program or showing how various partners mightcollaborate to approach a nagging problem in anovel way. The Federal Government is pivotal forsustaining the policy climate and catalyzingchange: If there is a national will, there is a way.

Chapter 1

Shaping the Science andEngineering Talent Pool

To the Committee [the President's Science Advisory Committee], enhancingour manpower supply is primarily a matter of quality not quantity, not amatter of diverting more college students to science and engineering, but of

providing for more students who have chosen this career routethe opportunity to continue their studies.

All scientists and engineers were once children:Families, communities, and the ideas and imagespresented by books, magazines, and televisionhelped form their attitudes, encouraged their in-terest, and guided them to their careers. Schoolsrefined their talents and interests, prepared themacademically, and gave them confidence by rec-ognizing their aptitude and achievement.

The importance of families and other out-of-school influences on this process can hardly beoveremphasized. Students form opinions andlearn about science and scientists from familiesand friends, from the media, and from places suchas science centers and museums, summer camps,and summer research experience. Equally, fam-ilies, friends, and the media can dull interest inscience. Nevertheless, it is largely schools, throughpreparatory courses in mathematics and science,testing methods, and teaching practices, that de-termine how many young people will preparesufficiently well for science and engineeringcareers (and for other careers). It is in the Nation'sinterest to see that schools provide the widest pos-sible opportunities, and the best possible educa-tional foundations for the study of science andengineering.' Some schools meet these goals, but

'Unless otherwise noted, this technical memorandum is con-cerned exL!usively with students' interest in naturalscience and engi-neering subjects. The adequacy of the preparation of future sodalscientists is not considered

many do not. A small minority of determined stu-dents no doubt can triumph over poor teaching,inadequate course offerings, and overrigid or bi-ased ability grouping or tracking. For mostevensome of the most talentedthese failings of theschools can kill interest and waste talent.

Of particular concern are women and some ra-cial and ethnic minorities, who together representa large reservoir of untapped talent. Minoritiesin particular will make up larger proportions ofthe population in the future. Identifying andmotivating talented minority youngsters is an in-creasingly important necessity for schools.

Concern about the quality of science and math-ematics education is also part of a broader con-cern about the Nation's schools. The objectives,funding, quality, and content of American edu-cation are all currently being debated, and a va-riety of remedies have been proposed.'

PREPARING FOR SCIENCE AND ENGINEERING CAREERSIn theory, the preparation of those intending

to become scientists o engineers is assumed tobe more intensive than that required of the en-tire school population. In practice, the interest ofboth groups must be stimulated. All students needfundamental preparations in mathematics and sci-ence in the early years of school. The broad goalof improving the understand'ng of science andtechnology by all high school graduates (oftencalled scientific or technological literacy) is veryclosely tied to that of educating future scientistsand engineers. Only at the high school level,where the courses chosen by each stream divergesignificantly, does this tie begin to loosen.

The Pipeline Model

The path by which young people approachcareers in science and engineering is commonlyvisualized as a kind of pipeline. Students enter thepipeline as early as third grade, where they be-gin to be channeled through a prescribed level andthen sequence of preparatory mathematics andscience courses. This channeling pervades the un-dergraduate and graduate studies that train andcredential them as professionals. Many studentsdrop out along the way, losing interest or fallingbehind in preparation. Few, it is generallythought, enter the pipeline after junior highschool. In fact, students' intentions remain vola-tile until well past high school, with substantialnumbers entering the pipeline (by choosing sci-ence and engineering majors) by their sophomoreyear of college. Many late entrants are relativelyill-prepared, however, and may suffer attritionon their path to a baccalaureate.

The ripeline model projects the supply of fu-ture scientists and engineers on the basis of thedemographic characteristics of successive birth co-horts. Bu'. this process is complicated. Careerchoices, perceptions of opportunities, Knowledgeof employment markets, and other influencesdraw students into and out of the talent pnol.Changing educational standards and practices alsoinfluence the size of this pool.

The education system thus can be thought ofas a kind of semipermeable, or leaky, pipeline,

with many points of entry and exit through whichdifferent students pass with different degrees ofease. Entrance to and persistence in this semi-permeable pipeline vary with job opportunitiesas well as with individual propensities towardknowledge and personal fulfillment. In fact, fieldsof science and engineering offer widely differentincentives that reflect economic and social trends.Thus, the semipermeable pipeline should bethought of as branched, with openings into di-verse job markets and careers.

Influences on the Future Compositionof the Talent Pool

These observations suggest that the talent pcolcan Pi., enlarged, and changing demographics sug-gest that it must be enlarged. If schools were moregenerous in identifying talent, and urged college-preparatory mathematics and science courses onmore students (not just those who believe they"need" them for career purposes), both the sizeand quality of the talent pool would be improved.Our scientists and engineers would be more nu-merous, better trained, and drawn from a popu-lation more representative of American society.

Yet the Federal Government is limited in its im-pact on elementary and secondary education:schools are State and local responsibilities. Re-search, curriculum development, demonstrationprojects, equity, and leadership ("jawboning") aretraditional Federal roles, but applying the resultsto classrooms is up to the State education author-ities and the 16,000 local public school boards.Change, in this environment, is slow to come.Another reason for a limited Federal role is thatscience and mathematics education is butone partof a constellation of educational activities. Teach-ing, testing, and tracking practices are deeplyembedded within the schools. Improvements inscience and mathematics education are closely re-lated to reforms in education overall.

Demographic Trends

Almost all of those who will be the collegefreshmen of 2005 were born by 1987. Knowledgeof current birth patterns allows us to make very

16

reliable forecasts of the size and the racial and eth-nic composition of the college-age population forthe next 18 years, and very good estimates evenfarther into the future.'

There are two prominent trends already appar-ent. The first is that the number of 18-year-oldsis declining, and will bottom out by the mid-1990s. The second is that racial and ethnic mi-norities today form an increasing proportion ofthe school age population.' However, the abso-lute number of Black 18-year-olds is currently fall-ing, just like the number of white 18-year-olds (butthe Black birthrate remains higher).

In general, America's schoolchildrL . will lookincreasingly different from past generations. AsHarold Hodgkinson writes:

. . . there will be a Black and Hispanic (Mexican-American) Baby Boom for many more years. His-panics will increase their numbers in the popula-tion simply because of the very large numbers ofyoung Hispanic females. These population dy-namics already can be seen in the public schools.Each of our 24 largest school systems in the U.S.has a "minority majority," while 27 percent of allpublic school students in the U.S. are minority.

. . Looking ahead, we can project with confl-uence that by 2010 or so, the U.S. will be a na-tion in which one of three will be Black, Hispanic,or Asian-American.'

What is unclear is how this demographic tran-sition will translate into college attendance andpursuit of science and engineering degrees. Vari-ations by region and social class, as well eth-nicity, complicate predictions. These are somecurrent trends:

'The actual size of the college freshman class is also determinedby the number of older people that enter higher education. At themoment, many people older than the traditional college-going ageare indeed entering higher education. In 1985, over 37 percent ofthose enrolled in college were 25 years of age and older.

But thereis no analytical reason why such a balance should exist. Still, thissocial goal encompasses the widely embraced motives of promot-ing equal opportunity, maximizing utilization of available talent,

If achievement testing,tracking, sexism, and racism in the classroom, orsome combination of these and other factors, pre-vent success, it is because the system ignores in-dividual differences in intellectual developmentand discourages capable students from becomingscientists and engineers. Such an outcome wouldbe tragic for the Nation.

The science and engineering talent pool is notfixed either in elementary or in secondary school.A determined core group is joined by a "swinggroup" of potential converts to science and bylate-bloomers, so that the future supply of stu-dents who will take degrees in science and engi-neering is not determined solely by the size anddemographic composition of each birth cohort.The past interest and performance of female and

Comparisons on minority work force participation should gen-erally be made with regard to age, because racial and ethnic com-position varies by birth cohort. Other considerations may Includeregional demographic variations, enrollment and educational sta-tus, and economic status of the reference population.

Schools need to adjust to an increasing proportionof minority children.

minority students in science and engineering fieldsis a tenuous basis for concluding that a shortageof scientists and engineers is inevitable. Ratherthan accept demographic determinism,3 OTAhas chosen to investigate the formation of the sci-ence and engineering pool in high school and as-sess how the structure of schooling identifies, rein-forces, and perhaps stifles aspirations to careersin science and engineering.

Figure 1-2 documents the flow ofstudents out of and into science and engineeringfields, and into the four field categories, over theintervals formed by the three survey points(sophomore year of high school, senior year ofhigh school, and sophomore year of college).

Between sophomore and senior years of highschool, the figure shows that, in every field cate-gory, more students came into each of the fourfields than persisted in them. Movement in fromthe nonscience category was more common thanmovement between science field categories. Pat-terns of persistence were less clear during the tran-sition from senior year of hig., school to sopho-more year of college. In all field categories exceptengineering, more students moved in than per-sisted.

Overall patterns of persistence are presented infigure 1-3, which shows the proportion of those

their high school senior year (and 34 percent ofthose in the sophomore year of high school)stayed with their plans."

OTA's analysis of the HS&B survey shows thatnatural science and engineering attract some newadherents both in the later years of high schooland the early years of college. The die is not castin the early stages of the educational process; somestudents (approximately equal in number to thosealready in the high school science and engineer-ing pool) enter that pool long after many analystsassume that definitive career choices have alreadybeen made. The interest is there; the challenge fac-ing educational institutions is to capitalize upon it.

Academic Preparation of Science andEngineering v. Nonscience Students

The challenge of preparing future scientists andengineers is much more than simply sparking in-terest in students; it calls equally for preparationthrough coursework and a willingness to bringnew entrants to the pipeline "up to speed." Dataon new entrants reveal a mixed picture: many are

very well prepared, but others take nontraditionalroutes and thus require extra help in mathematicsand science courses.

Table 1-1 shows some of the characteristics ofstudents planning natural science and engineer-ing majors at the three survey time points. It alsoshows that the proportion of this group thatscored above average on the HS&B achievementtest" increased at each time point. About two-thirds of those students interested in science andengineering majors in 10th and 12th grades scoredabove average on these tests, but more than three-quarters of those planning such majors as collegesophomores did so. This finding suggests thatmany of the new entrants to the pipeline are likelyto be of high ability.

In addition, the proportion of students plan-ning natural science and engineering majors whohad been enrolled in the academic curriculumtrack increased at each time point until it reached75 percent in the college sophomore year. Never-theless, the corollary of this findingthat 25 , er-cent of those seriously planning science and engi-

neering majors enrolled in the vocational andgeneral tracks in high school (with presumablyless access to college-preparatory courses in math-ematics and science)indicates that the scienceand engineering pipeline contains some late-comers. Significant numbers of students are ac-tive participants in the college segment of the sci-ence and engineering pipeline without two of thetraditional credentials of a future scientist andengineer: high ability manifested early on and aca-demic track preparation."

In a separate analysis (see table 1-2) of studentswho entered the pipeline from nonscience fields,either in their high school senior or college sopho-more years, OTA found that these students, onaverage, had lower scores on achievement teststhan did those who persisted in science at all threetime points. The "in-migrants" to science and engi-neering majors had taken fewer mathematics andscience courses and were more likely to be Black,Hispanic, or female than their "determined" sci-

ence peers. Nevertheless, 70 percent of the in-migrants had been in the academic curriculumtrack and had high school and college grade pointaverages (GPAs) comparable to those who per-sisted in science and engineering throughout.

In a further comparison of those who switchedfrom a nonscience to a science field during theirlast 2 years of high school with those who per-sisted in a nonscience field (see table 1-3), statis-tically significant differences were found in thecourse-taking patterns of the two groups. In-migrants to the science and engineering pipelinewere more likely to have taken algebra II, calcu-lus, chemistry, physics, or biology than their non-science peers, and subsequently recorded higherGPAs in mathematics and science courses. Still,they were on average less well prepared than thosewho stayed with science plans from their highschool sophomore to their college sophomoreyears.

The analysis of the high school class of 1982illuminates several findings that demand rethink-ing of how the science and engineering pool forms.Taken together, these findings lend support to therecent observation of the National Academy of

INTEREST AND QUALITY OF SCIENCE- ANDENGINEERING-BOUND STUDENTS

Interest in science and engineering, clearly, isnot enough. The ultimate health of the science andengineering work force also depends on anotherkey factorthe quality of students.16 Science

u'There is little agreement on how the "quality" of high schoolstudents should be measured. Achievement test scores are only oneindicator. Just as important are students' understanding of the processof science, attitudes toward science and engineering, language skills,

and engineering majors have traditionally hadabove average GPAs, college admission testscores, achievement test scores, and other mar-kers of quality.

and learning how to learn more effectively. Because there are noconsistent data on these latter attributes, achievement test scoresare here used as proxy for quality.

24

In recent years, somewhat fewer college fresh-men with "A" or "A-" high school GPAs havechosen science and engineering majors, while in-creasing numbers name preprofessional and busi-ness majors. Yet the proportion of science- andengineering-bound students who score above 650(of a maximum of 800) on the Scholastic Apti-tude Test (SAT) mathematics test" has increasedsomewhat between 1975 and 1984. About 44 per-cent of those who score above the 90th percen-tile on the SAT mathematics test say they planscience and engineering majors. The average scoreof all those scoring above the 90th percentile onthe SAT mathematics test increased from 623 to642 in the last 5 years."

It is widely believed by college educators thatthe quality of high school students who are plan-ning science and engineering majors may bedeclining compared to their predecessors. Whilethis belief has probably been held by all teacherswho try to transmit knowledge to their juniors,there is little evidence to support it. Although SATscores are an imperfect measure of the quality ofstudents, the average SAT score of all studentsplanning science and engineering majors declinedbetween 1975 and 1983 (parallel to the decline inscores of the entire population of test-takers dur-ing the period from 1963 to 1981). The SAT scoresof this group, however, have risen somewhat since1983. The sources of increases and decreases inSAT scores provoke complicated and controver-sial debates in educational assessment, but thereis some consensus that about one-half of the long-term decline during the 1960s and 1970s in theSAT scores was due to changes in the composi-tion of the population of students taking the test.The remaining decline has been attributed to de-creased emphasis on academic subjects by schools,

"However, many science- and engineering-bound student:, takethe American College Testing program test instead of the Scholas-tic Aptitude Test. Data on the science- and engineering-bound amongthe American College Testing program takers are not available

"In particular, there are indications that highly talented v .atemales, a traditional source of scientists and engineers, are increas-ingly being attracted to these majors. Mechanisms for increasingthis group's participation need to be devised as well as those to in-crease the participation of women and minorities. See Office of Tech-nology Assessment, op. cit., footnote 11.

and social factors. The recent increases are evenless well understood."

Overall interest in science and engineering ap-pears to have increased since the time of the ma-jor longitudinal study centering on the high schoolclass of 1972.20 Since that time, there have beenconsiderable shifts among fields within the scienceand engineering majors, often in response to em-ployment markets. For example, the late-1970sand early-1980s saw a rapid increase in interestin engineering and computer science majors (fresh-man interest and college enrollment in engineer-ing approximately doubled during that time), butsome decline of interest in physical science majors.

international Comparisons

There is also current concern that America'sbest students are of inferior quality compared withtheir peers in other countries. Two recent in-ternational comparisons of achievement scoreslargely support this concern, but do not defini-tively explain the cLuses of these differences (al-though they suggest the curriculum as a culprit).In particular, interpretation of these data is com-plicated by major differences in the structure ofeducation in different countries. (More detail onthe mathematics and science educational systemsof other countries is found in app. B.)

data indicate that the performance in most sci-ence and mathematics subjects of U.S. science-and engineering-bound students is inferior to thatof their counterparts in many other countries, in-cluding Japan, Hong Kong, England and Wales,and Sweden. One finding from the science studiesis that the proportion of each nation's cohort of18-year-olds who take college-preparatory sciencecourses is apparently smaller in the United Statesthan in other countries."

Data from the first international mathematicsand science studies (done in 1964 and 1970, re-spectively) indicate that the United States laggedbehind other nations even then. For example, inthe first international science study, students inAustralia, Belgium, England and Wales, Finland,France, the Federal Republic of Germany, theNetherlands, Scotland, and Sweden scored abovetheir peers in the United States (Japan did not par-ticipate). And, in the similar mathematics study,students in the United States scored lower thanall of the above countries as well as Japan. Be-cause there were few common test items betweenthe first and second tests, and because data onthe demographic and other characteristics of thegroups tested were not collected at both timepoints, it is difficult to determine reliably fromthese studies whether achievement in the UnitedStates (or in any other country) has improved ordeclined. These studies suggest that, comparedwith other countries, the United States has fared,and continues to fare, poorly in the mathemati-(continued from previous page)Perspective (Champaign, IL. Stipes Publishing Co., January 1987),pp. 22-30, F. Joe Crosswhite et al , Second International MathematicsStudy.

For example, in these data, only 1 percent of American highschool students are reportedly enrolled in chemistry and physics,but this refers only to seniors in high school who had taken secondyear chemistry and physics, not all students who took thesecourses(Richard M. Berry, personal communication, August 1988) In Can-ada, the numbers are 25 and 19 percent for chemistry and physics,respectively, and, in Japan, 16 and 11 percent, respectively. Note,however, that these enrollment data for the United States paint aconsiderably more pessimistic picture than earlier data on course-taking patterns has revealed (see ch. 2), and, due to small samplesizes, are subject to considerable uncertainty.

Interest in Science and EngineeringAmong Females and Minorities

Females and the members of some racial andethnic minorities are represented in most fields ofscience and engineering in numbers far below theirshares of the tot-1 population, a difference thatemerges well before high school."

Female inten_st in science and engineering isconcentrated in the life and health science, andless so in more quantitative fields such as engi-neering and the physical sciences and mathematics(figure 1-4). Black and Hispanic high schoolseniors are about one-half as likely to be inter-ested in careers in the physical sciences and math-ematics as whites, and Blacks are about one-halfas likely to be interested in engineering (figure 1-5).24 Some of this difference may be due to thefact that Blacks and Hispanics are less likely togo on to college than whites.

Why are females and minorities less likely thanmales and whites, respectively, to major in sci-ence or engineering? What can be done about it?Discussion of these issues arouses vigorous debate,which stems in part from deeply embedded so-cial attitudes and expectations about the roles andcontributions of females and racial and ethnic mi-norities to American society, the professions, andspecifically to the science and engineering workforce .25

Differences Between the Sexes inInterest in Science and Engineering

There are considerable differences by sex in thenumber of students interested in science and engi-neering fields. Of those interested in life and health

Males and females appear to differ strongly intheir interest in highly quantitative sciences.Somewhat more males than females enroll in highschool _.:,,urses leading to these fields, but not somany more as to explain the size of the differencein interest between the sexes. Females also tendto score lower on mathematics achievement tests,even when allowances art: made for the fewercourses they take compared to males.

Many researchers beii. we that the differencesare primarily or totally cau.-d by the differen-tial treatment that boys and girls receive frombirth. Parents, friends, teachers, and counselors,it is argued, encourage males to be interested inmathematics and science and discourage females.Over time, females come to feel less confidentthan males about mathematics, come to believethat they do not have mathematical "talent,"study mathematics less intensively, and hencescore lower on achievement tests. Interest in this"environmental" hypothesis has led researchersto try to ascertain whether sex differences in in-terest or test scores can be related to thesefactors .27

It is unlikely that the controversy over the ori-gin of gender-related differences in demonstratedmathematical ability will be resolved any timesoon, as so many different factors must be con-trolled in studies making male-female compari-sons. OTA concludes that effective steps can betaken to encourage females to enter science andengineering without detailed knowledge of thereasons for sex differences in mathematics achieve-ment and for interest in science and engineering.

There is no evidence that the rate of learningof mathematics by males and females is different.If there are differences in the preparation for, ori-entation to, or talents of males and females in sci-ence, they can be remedied. Among such remediesare programs to sensitize parents, teachers, andcounselors to their conscious and unconsciousdifferential treatments of boys and girls.3° Schools,

and especially guidance counselors, can help sig-nificantly by encouraging females who do wellin mathematics to take advanced mathematicscourses. Schools should also encourage femalesto participate fully in hands-on scientific experi-ments. The encouragement of females to pursuescience and engineering careers must counter con-tinuing and pervasive, albeit decreasing, discrimi-nation against females in the science and engineer-ing work force, as indicated by lower salaries fornew graduates and fewer females in tenuredfaculty positions.

Reasons Why Minorities Are NotWell Represented in Science

Blacks show interest in science and engineer-ing and, in particular, in careers in engineering,mathematics, and computer science." The chal-lenge is to convert this interest into well-preparedfuture scientists and engineers.

Development of interest and talent in scienceand engineering by Blacks is stultified by theirrelatively lower average socioeconomic status andmore limited access to courses that prepare themfor science and engineering careers. Minoritiesalso sense hostility from the largely white scienceand engineering work force and develop low ex-pectations for themselves in science and mathe-matics courses. For some, sadly, success in aca-demic study is scorned by their minority peers as"acting white." Larger proportions of minoritiesdrop out of high school than do whites, reducingthe potential talent pool for science and engineer-ing. And far fewer Black males than Black females2repare for college study, a pattern which is in-creasingly common as Black males favor military

Schools, school districts, and States need to domuch more to help minorities gain access to sci-ence and engineering careers. Teachers need to besensitized to minority concerns and to involve allstudents in mathematics and science experiences,such as laboratory experiments. Schools need todevelop better guidance counseling, and inculcatehigher expectations for minorities among coun-selors, teachers, and students. Schools and schooldistricts also need to improve their course offer-ings and ensure that all students have access to

SCHOOLS AS TALENT SCOUTS

The goals of excellence and equity both dependon taking full advantage of the Nation's talent.Doing so depends on having schools act in largemeasure as talent scouts. Instead, the schools haveoften acted as curricular traffic cops, encourag-ing the obviously talented, and culling out thosewho do not display the conventional signs of abil-ity and drive at an early age Too many students"never play the game" of science. (See box 1-A.)The result is a waste of talent.

Similar wastes of nonscientific talent undoubt-edly take place. The importance of high school

the preparatory courses leading to a science andengineering degree. And States and school districtsneed to ensure that schools with high minoritypopulations receive a fair share of financial, teach-ing, and equipment resources, given that suchschools are often in poor areas."

Undertaking such reforms will be difficult foran education system that changes very slowly. Inany event, such actions still will not overcomewider societal pressures that minorities believe de-ter them from science and engineering careers.Specific intervention programs (discussed in ch.5) are needed to overcome these deterrents.

33A ventable flood of successful interventions with minority stu-dents, in schools and out, is detailed in Lisbeth B. Schorr, WithinOur Reach Breaking the Cycle of Disadvantage (New York, NY-Anchor Press Doubleday, 1988), especially chs 8-12.

preparation in science and mathematics to futuresuccess in these careers, though, makes waste par-ticularly serious in these fields. In the future,schools will need to cast their nets wider in iden-tifying potential scientists and engineers, going be-yond the standard model of talent. The growingethnic and cultural diversity of young Americansmakes this task both more challenging and moreimportant. The remainder of this report will de-tail the steps schools and communities might taketo meet this national need.

Box 1-A.Never Playing the Game

Learning scienceits theories, its parameters, its contextcan be likened to learning all the rules ofa sportthe facilities needed for playing, the scoring, the timing, the uniforms. To prepare to play, onemust develop physical skills by means of strenuous exercise and conditioning. Such skill development canspan great time periods and demand much energy, commitment, and sacrifice. But, most potential playersare willing to devote whatever time and work are needed to succeed, because once they reach the playingfield, their effort will be rewarded.

In typical science teaching, we ignore the lessons we might learn from sports. We pronounce sciencea fantastic gamethat all should learn to play it. We spend years teaching background material, laws,rules, classification schemes, and verifications (disciplines) of the basic game. We plan activities for ourstudents designed to develop in them specific skills that the best scientists seem to possess and use. Webelieve that proficiency with these skills is an important part of an education in science. It is as if we weredeveloping conditioning exercises to train our students for the science they may actually do at a future time.

Unfortunately, however, our students rarely get to playrarely get to do real science, to investigatea problem that they have identified, to formulate possible explanations, to devise tests for individual expla-nations. Instead, school science means 13 years of learning the rules of the game, practicing verification-type labs, learning the accepted explanations developed by others, and the special vocabulary and the pro-cedures others have devised and used.

If potential athletes had to wait 13 years before playing a single scrimmage, a single set, a single quar-ter, how many would be clamoring to be involved? How many would do the pull-ups and the sit-ups?How many would learn the rules if there were no rewardsuntil collegefor those who had practicedenough to play?

We expect much in science education! Could on.. of our problems be too much promise of what sci-ence is really like at a date much too far removed from the rigor and practice science demands? Thirteenyears of preparation is a long time to wait before finding out whether a sport (or career) is as satisfyingas one's parents and teachers suggest it will be.

To prepare for the game of science for 13 years without even an opportunity to play is a problem!Like athletes, science students may need to play the game frequently, to use the information and skills theypossess, and to encounter a real need for more background and more skills. Such an entree to real sciencein school could result in more students wanting to know and wanting to practice the necessary skills. Now,we lose :oo many students with only the promise that the background information and skills we requirethem to practice will be useful.

Paul Brandwein asserts that most students never have a single experience with real science throughouttheir whole schooling. He has written that we would have a revolution on our hands if every student hadbut one experience with real science each year he or she is in school. Are we ready for such a revolution?Can we afford not to clamor for it?

To spend 13 years preparing for a game, but never once to play it, is too much for anyone. Teachersand students alike are more motivated when they experience real questions, follow up on real curiosity,and experience the thrill of creating explanations and the fun of testing their own ideas. Real science mustbecome a central focus in the courses we call scienceacross the entire K-12 curriculum.SOURCE Quoted from Robert E. Yage, "Never Playing the Game," The Science Teacher, September 1988, p 77

Formal Mathematics andScience Education

There has been widespread concern among scientists and educators alike overthe failure of the instructional programs in the primary and secondary schoolsto arouse greater interest and understanding of the sciertific disciplines. . . .

There is general agreement that much of the science taught in schools todaydoes not reflect the current state of knowledge nor does it represent the best

possible choice of material for instructional purposes.

THE NATION'S SCHOOLS

About 75 percent of each birth cohort nowgraduates from high school. Elementary and sec-ondary education takes place in over 100,000schools, employing 2.5 million teachers and en-rolling about 45 million students.' It costs $170billion per year, about $4,000 per studentor 4percent of the annual gross national product.2Public education, including higher education, isthe single largest component of State spending.Nationally, the States' contribution to the cost ofpublic school education is about 49 percent of thetotal; 45 percent comes from local sources and theremaining 6 percent from the Federal Govern-ment. The Federal Government's contributionpeaked at about 10 percent of the total from 1978to 1''x0.3 (See figure 2-1.) The balance among lo-cal, State, and Federal funding varies significantlyfrom State to State, however. New Hampshire has

The bulk of the cost of education is inproviding buildings and paying salaries forteachers and other staff. A tiny proportion is spenton instructio,sal materials, such as textbooks andlaboratory equipment.' Private schools arefunded from tuition charged to students, althoughthey also receive tax benefits and participate insome Federal aid programs. They enroll about 10percent of students .6 (See figure 2-2.)

Although control over public education is inthe hands of the States and the school districts,schooling across the Nation displays remarkableuniformity.' Compulsory education generallybegins at age 6, in grade 1; for those who persist,free public schooling ends in grade 12 at age 18.There are three commonly used school classifi-cations: elementary (kindergarten to grade 5, 6,or 7); middle or junior high (grade 6, 7, or 8 tograde 8 or 9); and high (grades 9 or 10 to 12).Schools award grades on a scale that normallystretches from I to 4, curricula and course titlesare fairly uniform, and a student's grade pointaverage is nationally recognized as a measure ofthe student's progress.

The Nation's 84,300 public schools are c.3n-trolled and run by autonomous school districts,subject to State laws and systems of organization.These school districts are of very unequal size:the largest 1 percent educate 26 percent of stu-dents, while the smallest 43 percent educate only4 percent of students. The trend is toward con-solidation of smaller districts, and the number ofschool districts has fallen in 50 years from 120,000to slightly less than 16,000 today.° Most schooldistricts, although geographically coextensive withlocal governmental units such as counties and cit-ies, raise their own funds through local taxes andbond issues, and are run by locally elected schoolboards. In other districts, funding and control arethe responsibilities of counties and cities.

Just as education nationally displays diversityand uniformity, so it is with mathematics ar.i sci-ence education. The National Science TeachersAssociation estimates that at least 50 percent (8.3

COMPONENTS OF MATHEMATICS AND SCIENCE CURRICULAFor many children, the content of mathematics

and science classes and the way these subjects aretaught critically affect their interest and laterparticipation in science and engineering. The ef-fectiveness of different teaching techniques isaddressed in the next chapter, but this section re-views the controversies over the typical Americanmathematics and science curriculum, the allegeddullness of many science textbooks, and the ex-tent to which greater use of educational technol-ogy, such as computers, could improve the teach-ing of mathematics and science."

Many mathematics and science educators arecritical of the quality of the mathematics and sci-ence curricula in use in most schools. They seethe curricula as slow-moving, as failing to drawlinks between scientific and mathematical knowl-edge and real-world problems, and as relativelyimpervious to reform."

'Similar criticisms are made of the entire K-12 cumculum that,according to many observers, fails to draw links between separatecourses or between its content and the workings of the outside world.A recent Carnegie Foundation report called for ". . . a kind of peace-time Manhattan Project on the school curriculum. . . ." which would" . . . design, for optional State use, courses in language, history,science and the like and . . . propose ways to link school contentto the realities of life." The Carnegie Foundation for the Advance-ment of Teaching, Report Card on School Reform: The TeachersSpeak (Washington, DC: 1988), p. 3. See also Fred M. Newman,"Can Depth Replace Coverage in the High School Curriculum," PhiDelta Kappan, January 1988, p. 345.

"Attempts were made to improve mathematics and science cur-ricula in the 1960s via several projects funded by the National Sci-ence Foundation. These projects did have some success, and haveaffected overall curricula in these subjects in particular by stressingthe use of practical experiments. Details on these federally fundedprograms appear in ch. 6.

Typical Mathematics andScience Curricula

The mathematics and science curricula in usein schools are fairly standardized, due to the wide-spread use of the Scholastic Aptitude Test andAmerican College Testing program for college ad-missions, college admission requirements, theworkings of the school ti xtbook market (whichensures considerable uniformity of content), andthe need to accommodate students who transferfrom one school to another. Nevertheless, thereare important differences in the problems of cur-ricula between mathematics and science."

In mathematics, grades one to seven are de-voted to learning and practicing routine arithmet-ical exercises. In grade seven, the more advancedstudents may move on to take courses that pre-pare them for algebra, but the most commonlyoffered class is "general mathematics." The mostable and motivated take algebra in grade eight (iftheir school offers it), and there is some evidencethat the number of algebra classes in grades sevento nine is rising." In higher grades, students goon to courses in advanced algebra (also knownas algebra II), geometry, trigonometry, and eitherprecalculus or calculus (where these are offered).(See figure 2-3.) About 10 percent of each cohort

The abstract and undemanding pace of themathematics curriculum at all levels has beenwidely criticized recently. Many mathematics edu-cators believe that there is too much emphasis onarithmetical drill and practice, as opposed to anemphasis on understanding mathematical con-cepts and applications. Many highly able studentsin mathematics, likely future science and engineer-ing majors, report that the average curriculuiproceeds at too slow a pace." The fact that hand-held calculatorsin widespread use in everydaylife nationwide for over a decade are still rarelyfound or used in mathematics (and science) class-

rooms is particularly criticized. A 1985 surveyfound that about one-half of mathematics and sci-ence classes in grades 10-12 used calculators atsome point, but the proportion was much lowerin earlier grades (14 percent in the case of gradeK-6 mathematics classes)." Another surveyfound that almost all students rep.:sted that ei-ther they or their family owned a calculator, butless than one-quarter said that their schools hadcalculators for use in mathematics classes."

Many mathematics educators also note that themathematics curriculum was largely left out ofearlier reform efforts, which concentrated mainlyon science. The experiments in "new math" lefta bad taste in many mouths, and there still re-mains deep suspicion among teachers, parents,and school boards of attempts to develop a "new"mathematics curriculum. Nevertheless, mathe-matics educators are using international compar-isons of curricula, teaching practices, and achieve-ment test scores to demonstrate the inferiority ofmany American mathematics curricula.19 TheNational Council of Teachers of Mathematics isundertaking a consultation program to developcurriculum and assessment standards for schoolmathematics, and the Mathematical Sciences Edu-cation Board, part of the National Research Coun-cil, is launching a broad-based reform programdesigned, in part, to alert parents, school boards,and teachers of the need to improve school math-ematics. (See box 2-A.) Particular efforts are alsobeing made to improve the teaching of calculusincreasingly taught in high school and, by manyaccounts, appallingly taught at the collegelevel."

The primary purpose of the Board is ". . . to provide a continuing national over-view and assessment capability for mathematics education." The Board works under the auspices of theNational Research Council, and on it sit mathematicians, mathematics educators, and people familiar withschools and school systems. The Board is working on increasing public understanding of school mathe-matics issues, raising national expectations for mathematics teaching and learning, and reaching a con-sensus on goals and education for future mathematics teaching. It is planning ways to help States and schooldistricts improve their performance in mathematics .2

In science, until grade eight, most students takegeneral science courses. In grade nine, upon trans-fer to high school, they typically take general sci-ence, biology, then chemistry, earth science, andfinally physics. About 20 percent of high schoolgraduates persist in science long enough to takephysics." In many schools, these courses are

taught separately, and teachers fail to draw thelinks and contrasts among the different science dis-ciplines. The typical order of their presentationbiology, chemistry, physicsis deeply ingrainedin the culture of American school science, butsome teachers feel that other arrangements wouldbe better, and would draw more effective links

About two-thirds of elementary scienceclasses use them,as do over 90 percent of elementary mathematics classes. The sur-vey also found that most teachers claimed to corer at least 75 per-cent of the book that they used. See Weiss, op. cit., footnote 15,tables 14 and 19. A similar survey of students found that threequarters of students in grade 7 and 11 reported using mathematicstextbooks in classes daily, and only 4 or 5 percent, respectively,"never" used textbooks in class. In grade three classes, more useis made of workbooks or ditto sheets than textbooks. See Dosseyet al., op. cit., footnote 18, p. 78.

as a monolith of unconnected and unchallenge-able "facts," which are learned only by those stu-dents with extraordinary memories and with anoverriding determination to pass the standardizedtests of their ability to recall such definitions. (Theneed to address "facts," as well as their interpre-tation and construction, is discussed in box 2-B.)As a result, students find the textbooks boring.For example, one recent review by a science edu-cator of a newly revised biology textbook notes:

[This] product offers facts, pseudofacts andcliches in a matrix of rote sentences and plentifulpictures. It continually fails to integrate informa-

tion, to explain concepts or to explain biology,and it is rich in absurdity. The writers reduce thetopic of "scientific methods" to two paragraphswithin a confusing passage on The Origin ofLife." . . . The book . . is attractive but scientif-ically meaningless.

[The book] pres'nts a frenetic display of factsa smothering blanket of factsand it will not in-spire scientific thinking in any student or teacher.At most, it will impart an artificial and shallowsense of learning while it damages imaginationand creativity.23

Box 2-B.Learning About Science and Processes of Advancing Scientific Knowledge

Science is widely equated by the American public with a huge body of knowledge about physical andhuman processes that the scientific research enterprise has created. Many teachers similarly equate sciencewith the mass of facts and material found in textbooks. Teachers report that their job is to cover as muchof this material as they can and get their students to learn and memorize it. Many teachers say that succes-sive editions of textbooks get bigger and more expensive, as more and more factual material is added. Infact, some teachers are very critical of many textbooks in current use because they feel that they conveya misleading impression of the reality of science and engineering. While scientists share the view that sci-ence is a large collection of facts, there are other important dimensions that science students must learnand appreciate to thrive in college-level study.'

Science is better viewed as a subject that embraces both a body of knowledge and the process by whichthat knowledge is developed and verified.' Future scientists andengineers need to know about what is al-ready known and about how new knowledge can be created' Most scientific knowledge rests on experi-ments that yield data. These data either confirm or fail to support hypotheses that scientists make aboutrelationships in the physical world. (Rare exceptions are wholly theoretical fields, where physical experi-ments are intractable and knowledge is built up by theoretical an&lysis.) Thus knowledge of how experi-ments are conducted, what sources of error there might be in them, how potentLilly contradictory evidenceis sought and evaluated, and how the results of experiments can be usedboth witri;, science and withoutisthe key to understanding the process of doing science.'

A further dimension to the study of science is that of its effects on society and its role in society andgovernment. This dimension is collectively known as "science, technology, and society," and is being in-troduced into many school science classes.'

'As the late Roger Nidiols, former director of the Boston Museum of Science, said about science: "We take a thing which is ementially a processand convert it into a reading wades.

The evidence is that both the economics of text-book publication and the politics of textbookselection result in "watered-down," poorly writ-ten, but attractive and fact-filled textbooks.'Some educators bitterly criticize the process oftextbook "adoption" (approved for use statewide)used in 22 States. These States have a great dealof control over the content of the books. As a re-sult, textbooks are designed to mee adoption cri-teria in the few key States such as Texas and Cali-fornia (in kindergarten to grade eight only) thatguarantee the largest market if the book is ap-proved. States that do not have textbook adop-tion mechanisms consequently have a more lim-ited choice of textbooks, because publishers arereluctant to incur the cost of producing new vol-umes for these smaller markets.

Because of the pressure to include material thatwi.. satisfy textbook adoption committees and inorder to outdo rival publishers, textbooks typi-cally are large and heavy, profusely illustrated,are often printed in full color, but are surprisinglyuniform in content. The books typically increasein size and weight with each edition, becomingmore expensive, harder to carry, and more diffi-cult for students to take home and study. The text-

Formal education relies heavily on textbooks marketedby major publishing companies. Most educators find

that these textbooks vary greatly in quality

books often include a huge quantity of material,in order to ensure that each State's recommerdedscience curriculum is covered and that ali inter-est groups are mollified. However, many impor-tant but controversial aspects of science, mostnotoriously the theory of evolution, may be omit-ted or given inadequate treatmen

Interest groups lobby State textbook adoptioncommittees to ensure that their own viewpoint isincluded, but the effect is that new text and pic-tures are addedmaterial is rarely deleted. Ulti-rnately, depth is sacrificed for breadth. And, be-cause the adoption process typically involves anexpert panel that quickly skims each volume, thetextbooks often are designed to have key wordsin prominent places and be attractively packaged.The result is often textbooks that are a "lowestcommon denominator" of inoffensive facts, lim-ited in conveying to students the process of con-structing new scientific knowledge or the uses thatare made of it. Some have described science text-books as "glossaries masquerading as textbooks."Often, the "facts" themselves are old or entirelydiscredited. As a recent analysis of the process oftextbook adoption notes:

We have dozens of powerful ministries of edu-cation [ States) issuing undisciplined lists of par-ticulars that publishers must include in the text-books. Since publishers must sell in as manyjurisdictions as possible in order to turn a profit,their books must incorporate this melange of test-oriented trivia, pedagogical faddism and incon-sistent social messages. . . . Under current selec-tion procedures, those responsible for choosingthe best among available books seem blind to theincoherence and unreadability of the book be-cause they are merely ascertaining the presenceof the reouired material, not its depth or clarity.'

In economic terms, the textbook market is quiteconcentrated, as indicated in table 2-1. For exam-ple, almost half of all elementary mathematicsclasses and 37 percent GI all elementary scienceclasses use one of the three most commonly usedtextbooks in these grades. Only a few textbookpublishers supply much of the market. Yet a num-ber of smaller publishers happily coexist along side

Despite these gloomy assessments, a recent sur-vey of mathematics and science teachers foundthat only a minority of them were concernedabout textbook quality.

thought it was a problem. Between 15 and 25 per-cent of teachers thought that the quality nf text-books was somewhat of a problem. Factors suchas large class sizes, inadequate access to com-puters, lack of funds for equipment and supplies,inadequate facilities, poor student reading abili-ties, and students' lack of interest were cited tobe more serious problems. Indeed, teachers ratedthe organization, clarity, and reading level of text-books favorably. Elementary '-eachers had morefavorable ratings of textbooks than did second-ary teachers.28

Textbooks pose several Lontradictions: mostteachers seem (rightly or wrongly) to like the text-books they use, many outside reviewers are skep-tical of the scientific worth of many mathematicsand science textbooks, there are apparently nooverwhelming barriers to entry to the market, andpowerful political and economic forces shape thedynamics of the textbook market. Devising "bet-ter" textbooks is not enough, for they must beadopted to be used and they are likely, on present

evidence, to be severely corrupted in the process.The best teachers have the ability to go beyondthe material in textbooks, to provide supplemen-tary material and examples, and to weave the con-cepts that the books try to explain into some co-herent whole. But many teachers do not have thetime, energy, or authority to use materials otherthan the approved texts.

Overall, the deficiencies, if any, in currentmathematics and science textbooks stem from thedivorce between the buyers and users of text-books. Greater teacher involvement i t textbookselection, a more courageous selection of mem-bers of textbook selection committees by States,and a greater participation by qualified scientistsand engineers in the textbook adoption processwill Wk.:, but not rectify, the problem."

Use of Computers in Mathematicsand Science Education

Computers offer new approaches for learningmathematics and science for all children, and helpprepare students for college courses and techni-cal careers that will demand familiarity with thetechnology." If used well and imaginatively,computers can increase students' interest and im-prove learning, particularly for both the most and

"There is a Federal role, too The National Science Foundationhas issued a "publisher initiative" that outlines criteria for neededstudent assessment matenals in baseline science development projectsfor the elementary grades and middle school. Since 1987, the Na-tional Science Foundation has funded seven "Troika" programs". . . intended to encourage partnerships among publishers, schoolsystems, and scientists/science educators for the purpose of develop-ing and disseminating a number of competitive, highquality, alter-native science programs for use in typical American elementaryschools." See the National Science Foundation, Science and Engineer-ing Education Directorate, Instructional MaterialsDevelopment Pro-gram, "Publisher Initiative" and "The Troika' Program," unpub-lished documents, July 1988.

Some schools, in particular science-intensive schools, havemore powerful computers, computerized laboratory instrumenta-tion, and computer-aided data processing equipment. Other infor-mation technologies, such as interactive videodiscs, are also powerfullearning tools but they are less widespread than computers. Calcu-lators, present in increasing numbers of classrooms, are hay.ng agreater effect than computers, because they reach many more stu-dents and are more readily linked in teachers' minds with existingcurricula items, such as arithmetic.

least advanced students. But the educational im-pact of computers is limited when the rest of theclassroom environment stays the same. Conclu-sive research on effectiveness is meager."

Computer technology and software are evolv-ing. Educators are still discovering both positiveand negative impacts on students, classrooms, andlearning; how best to use the technologies to im-prove learning; and what support is needed inteacher training, curriculum modification, and re-search. Use of computers by teachers and studentsis still quite limited, although their availability andthe equality of access enjoyed by different schoolsand students is improving. The use al _a future im-pact of computers depends on familiar featuresof the rest of the school system: curricula, time,quality of overall science and mathematics instruc-tion, and, most of all, the comfort and compe-tence of teachers with computers.

Nature and Extent of Use

The potential of computers is slowly being real-ized. Regular computer use is not extensive, al-though almost all schools now have at least somecomputers available. Primarily becatse of thesmall number of computers relative to students(the compute: -to- student ratio in science classesis estimated to be 1:15 in middle school and rang-ing from 1:10 to 1:17 in high school, which ishigher than the average in all subject areas), com-puters are most commonly used as infrequent en-richments rather than as an integral part of : :f-ence teaching." About one-third of high schoolmathematics teachers use computers in tit:. class-room." Nevertheless, much of this is occasional

A 1985survey found that over 90 percent of schools had access to com-puters, but that only in about one-quarer of mathematicsand scienceclasses was this equipment readily available. Often, it is shared withother classes, or kept in special-purpose rooms that must be sched-uled in advance Weiss, op. cit., footnote 15, table 68.

"Becker found 17 percent for middle and secondary schools,while the National Science Teachers Association found 26 uercentfor all schools with a grade 12 (all secondaryschools and a fr w mid-dle schools).

use, and amounts to a small fraction of instruc-tional time." A 1985 survey noted that". . . there is o.tly the hint that secondary schoolscience instruction might be profound:y affectedby computers. The impact is largay still in thefuture."

Computers are not used intensively in scienceclasses. (See figure 2-5.) In secondary school, only5 to 10 percent of computer use is for science; inelementary school, it is about 1 percent. Therehas been a slight decrease in the number of sci-ence programs available over the past 5 years,especially in chemistry and physics.

A unique application of computers in scienceis in the microcomputer-based laboratory (MBL),where computers can simulate experiments orprocess and display data obtained ft ml simulatedexperiments.36 (See box 2-C.) The use of sciencelaboratories in science teaching has declined formany reasons, but computers can reduce some ofthe barriers to laboratory work, such as the ris-ing cost of supplies, purchasing and maintainingequipment, concerns about safety hazards and lia-bility, limited teacher competence in experimentalwork, the complexity of some experimental pro-cedures, and the "one timelook quick" natureof many laboratories.37 MBLs can also help chil-

Besides limited access to machines, other im-portant barriers to more extensive use of com-puters are teachers' lack of familiarity with thetechnology and the lack of educational software(computer programs;. Surveys indicate that com-paratively few mathematics and science teachershave taken courses either in the instructional usesof computers or in computer agramming.

There are various ways computersare used to teach experimentation: to simulate experiments; to provide real-time, visual data analysis ofregular "wet" experiments in microcomputer-based laboratories; and, ia the NGS Kids Network, to usetelecommunications to link children across the Nation in a real experiment.The NGS Kids Network uses networked computers and telecommunications to link elementary schoolchildren around the United States. During a month-long 1987 pilot Kids Network project on acid rain,students in nine States did classroom work, collected rain samples, measured pH, and shared their resultsover a telecommunications network. A project coordinator analyzed the results and distributed them toall the participating classes. With the reach and immediacy of national data collection and analysis, thestudents could see their results, and those of all other students, overnight.The chief impact of the NGS Kids Network, as with much computer use, seems to be in getting chil-dren, teachers, and parents excited and involved. Enthusiasm generally improves learning. Formal evalua-tion of the impact of the Kids Network and computers on understanding science concepts and methods,however, is likely to be less clear-cut.

Results of the trial far exceeded expectations. The students puzzled over their measurements and wonderedwhy Nebraska had such an urexpectedly high level of acid rain. (In fact, this finding is in accord with recentEPA measurements.) They lean 10c1 about acids and bases, about dilution, pH scales, 'iLa range of accuracy ofmeasuring indicators, the possible effects of acid rain, and latitude and longitude. Students became engrossedin finding out more about the communities where the other sites were located. They learned vi..,Lible lessonsabou' the process of science, engaged in spirited discussions about scientific method, the validity of data, andthe need for care in measurement. Students were highly motivated, bringing in newspaper clippings, collectingadditional samples, and spontaneously writing to students at other sites and to public officials. Uniformly im-pressed by the unit, teachers enjoyed teaching it.'Future NGS Kids Network units will be self-contained, 1-month packages of classroom activitiz:, "Closeto home" topics such as water and air pollution, food growing, solar energy, and weather forecasting havebeen chosen because they adapt well to distributed, national observations and data collection. One teachercommented:

After they had brought in their samplesof rain water and saw that they had gotten different results, theydecided that they hadn't collected enough data. They made a judgement that they didn't have enough data tomake an accurate conclusion. i see that as a very important step in understanding acience. . . . They got themessage that science is a collective enterpriseas opposed to an individual one. That message came through verystrongly.'

Special resource materials, teacher training, and user-friendly software have been developed to makethe sophisticated units extremely easy for the novic.t student and teacher to use. To communicate results,all the teacher or student has to do is switch on the computer. Dissemination will be through the NationalScience Teachers Association, science centers, and the extensive National Geographic infrastructure.The Kids Network is being developed by the Technical Education Research Centers and is funded bythe National Science Foundation and the National Geographic Society. With the development costs thussupported, the costs t. the schools can be kept low; telecommunications costs are a large and uncertainfactor. Total development costs, including government and private grants and in-kind equipment and servicedonations, are estimated at a total of $5 million over 4 years.

tinues to be the subject where students are mostlikely to encounter computers. More software isavailable for mathematics than for any other sub-ject area, although most of it is for learning andpracticing basic skills.' For example, interactivecomputer graphics can be powerful in helping chil-dren construct graphs and isualize algebraic andgeometric functions.

Computer Impacts, Opportunities, and Needs

Computers offer the potential for individual-ized instruction. If carefully developed and used,computers and software can open doors to math-ematics and science for students, particularly fe-males and minorities, who traditionally have hadlimited interest or success in these curses. Inmany settings, however, computers can also rein-force existing patterns and stereotypes: boys tendto crowd girls away from computers, affluent chil-dren benefit from computers at home and moreextensive access at school. Little is known as yetof the impact of different kinds and intensity ofcomputer use on interest in, and preparation for,different college majors.

Computers also make it possible to offer coursesthat might not otherwise be available. Distance

learning or packaged computer courses can en-rich the schooling of advanced high school stu-dents or rural students in schools with limitedcourse offerings. Likewise, familiarity with com-puters is becoming expected of incoming collegestudents, particularly in science and engineering.If students do not have the opportunity to workwith computers, computers may becce yetanother barrier to attainment of educational goals.

A pressing need is to help current science andmathematics teachers become comfortable usingcomputers in the classroom and laboratory. Al-though most new teachers being trained are ex-posed to computers, many of them still report notbeing comfortable using them Technologytraining has unique aspects that distinguish it fromother inservice training, in particular a need forspecial facilities and equipment. Teachers musthave generous access to computers to use themeffectively.

Continuing research on learning and evalua-tions of the effectiveness of computer-aided edu-cation are needed. Trials of different schools andlearning structures would help in evaluating thestrengths and weaknesses of computer technol-ogies. The challenge is to measure the proLcss oflearning, and not just the content and outcomesof acquired knowledge. Another need is develop-ment of computz:-integrated curricula, whichbuilds the strengths of computers into curriculafrom the start rather than appending them to ex-isting curricular frameworks.

The Federal Government has helped schoolsacquire compuers, supported research on theiruses and their integration with curricula, and tosome extent augmented private sector devel-opment of hardware, software, and services."Some Department of Education funds, althoughnot specifically targeted to computers, have

VARIATION AMONG SCHOOLSAs any parent knows, schools vary in a myriad

of ways; their location, control, and funding mayaffect their children's progress. For example, thereis some evidence that private Catholic schools areespecially effective at channeling their studentstoward academic college education, owing to thepersonal attention and high expectations they givetheir students.43

OTA did not analyze data on the special fea-tures of mathematics and science instruction inprivate schools compared with public schools.Rather, it considered the contrasts among urban,suburban, and rural public :,:hoots, as related totheir respective socioeconomic settings and expec-tations of parents and other taxpayers. For exam-ple, urban school districts often have poor taxbases and cannot readily raise funds for educa-tion. Suburban school systems have much less dif-ficulty and can attract good teachers. There arecontinuing pressures for sor: e suburban and ur-

"James S, Coleman and Thomas Hoffer, Public and PrivateHigh Schools (New York, NY: Basic Books, 1987) is a recent anal-ysis of this proposition. Although this analysis does not specificallyseparate out mathematics and science education, the authors con-clude that the ethos of the community surrounding a school, in-cluding taxpayers and parents, is more important in explaining thesuccess of private schools than are particular actions that the schooltakes. Some argue that the political andbureaucratic mi' eux withinwhich public schools operate harms them. See John E. Chubb andTerry M. Moe, "No School Is an Island: Politics, Markets, and Edu-cation," The Brookings Review, fall 1986, pp. 21-28. Other analystshave found that any advantage in the outputs of private school sci-ence experiences are balanced by the strong self-selectivity of pri-vate school students See John R. Stayer and Herbert J. Walberg,"An Analysis of Factors That Affect Public and Private School Sci-ence Achievement," Journal of Research in Science Teaching, vol23, No. 2, 1986, pp 97-112

the Federal Government fund four mathematics and four sciencecumcula to meet the goal of a science and mathematics course eachyear of high school A rough estimate is that such developmentwould cost about $2 million ($1 to $4 million) per course. Develop-ment should include review of old and existing curricula. Distribu-tion and maintenance might total 25 percent of development costs,but could be recovered through a school user fee. Trials would needto be several years long.

ban school systems to merge or to share funds andresources, in the interests of both racial and fi-nancial equity. The health of inner city schoolswill be particularly impoeant in encouraging mi-nority youth to pursue science and engineeringmajors. The 44 largest urban school systems, rep-resented by the Council of Great City Schools,enroll aLout 10 percent of the entire school pop-ulation, but 33 percent of the Backs and 27 per-cent of the Hispanics in public schools. Theseschools also enroll a disproportionately largenumber of students whose family incomes are be-low the poverty line." Data from the NationalAssessment of Educational Progress (NAEP)assessments of science and mathematics achieve-ment indicate that students in disadvantaged vr-ban areas score an average of about 20 percentlower than the national average, while those insuburban areas score about 5 percent higher thanthe national average.45

Rural school systems face different problemsin providing high-quality education, particukrlyin advanced mathematics and science, to geo-graphically dispersed populations. While the daysof the one-school school district are passing, ru-ral districts still find it difficult to provide optionaladvanced mathematics and science courses andto attract the best teachers. These problems willgrow worse in areas of rural America that con-tinue to experience economic declines. Experi-ments are under way in some areas with distancelearning technologies and regional science highschools.`

Standardized Achievement Testing

Students take many kinds of tests throughouttheir schooling to measure their learning and mas-tery of skills. Such tests are used to sort studentsamong classes and tracks, to evaluate perform-ance, to check for special abilities (see section inch. 4 on programs for gifted and talented students)or learning disabilities, and to inform the collegeadmissions process. Tests of basic competenciesof high school graduates are growing in favor aspart of the movement toward increased educa-tional accountability. A 1985 survey found that11 States required such tests of high school grad-uates, and 4 had plans to institute such tests."

Many of these tests are of the familiar stand-ardized multiple-choice type. Scores report stu-dents progress both in absolute terms and rela-tive to the performance of their peers. Such testsare inexpensive to administer; scoring is oftendone by computer.

But testing is controversial on several counts.It is said to deter many students from preparingfor science and engineering careers. The tests arealso said to convey racial, cultural, and gender

A new federally sponsoredproject called ACCESS, in northwest Missouri, is designed to ex-pand rural students' access to higher education in all subjects. Leg-islation has been introduced to set up similar programs in otherStates.

biases against women and ethnic minorities thatostensibly lead to lower scores." Some claimthat testing has a pervasive harmful effect on thecurriculum: teachers invite students to parrot backfacts they have memorized, with the result thatstudents' higher order thinking skills are not ex-ercised." A recent issue of the Newsletter of theNational Education Association's Mastery inLearning Project put the issue most dramatically:

Perhaps it has been the failure to understandintelligencehow it is nurtured or stunted, howit works, how it should be measured, even whereit residesthat has dome the most damage to theeducation of children.

Because the workings and the vulnerability ofthe intellect have been so dimly understood byso many, teaching has oh.. i been rigidly fact-driven, heavily demanding of linguistic, logical,linear thinking skills, and often neglecting thoseaspects of learning that involve imagery, intuitive-ness, manual and whole body skills, and feelings.

Partly because of this failure of understanding,educational testing companies have continued toproduce, states to require, and schools to admin-ister, paper and pencil tests that, in purportingto measure student,' achievement, have succeededonly in labeling and limiting it.'

The current practice of educational testing ap-pears to constrict the pipelir 2 for future scientistsand engineers. It measures only a limited rangeof abilities and is often misused to deny studentsaccess to courses and encouragement that mighttip the balance toward their becoming scientistsand engineers. Alternative tests are being devisedto address, in particular, knowledge of theprocesses of science, familiarit7 with experimentaltechniques, and higher order thinking skills, butthe nagging problem will be resistance to theirreplication and large-scale adoption bs,th for class-room use and in the college admissions process."

"Nevertheless, it Is important to note that Asian students typi-cally do better than other groups on the mathematics portion ofthese tests, indicating the difficulty of pinning down exactly whatform any racial and cultural biases take.

tests are given great weight in admissions deci-sions by colleges and universities, any deficien-cies in the preparation or administration of thesetests could lead to "misassignment" of studentsamong colleges and majors, or the failure of stu-dents to be admitted to college at all. Standardizedtests have been important in college admissionsfor many decades, because they are economicalto administer and measure students nationallyagainst a common metric. But criticism of, in par-ticular, the SAT by activist groups such as theCambridge-based National Center for Fair andOpen Testing (FairTest) and others in educationis leading a small but increasing number of col-leges and universities to drop their requirementfor applicants to take the SAT."

Females, Blacks, and Hispanics, on average,score lower than males and whites on the mathe-matics and verbal portions of these tests. In rela-tion to disparities on the mathematics portion,some argue that this difference arises from therelatively poor preparation and limited numberof mathematics and science courses taken by thesegroups. But others say that subtle biases in thetests' design and administration are a cause ofsome of the disparity.m

One important trend in testing is the increas-ing number of advanced placement programs be-ing offered by schools. These prolrams give highschool students college credit in a particular sub-ject, based on the results of an examination whichinvolves both multiple-choice and written re-sponses. Many argue that this makes the advancedplacement a better test, although it is more ex-pensive than regular college admissions tests (cost-ing over $50 per test). The number of such testsbeing taken is increasing about 13 percent annu-ally, and about 20 percent of all secondary schools

'David Owen, None of the Above (Boston, MA. HoughtonMifflin, 1985): Robert Rothman, "Admission Tests Misused, Say,College Leader," Education Week, Dec. 9, 1987, p C. FairTest reportsthat at least 40 colleges now do not require either the Scholastic Ap-titude Test or the American College Testing program for college ad-mission. When colleges do not use (hese L.sts, they increase theweight that they place on other components of the admissions proc-ess, such as student transcripts, student essays, teachers and coun-selors' recommendations, and in-person interviews. These compo-nents arguably allow candidates to present a much fuller impressionof themselves as potential college students than do simple scoreson standardized tests.

and 10 percent of high school graduates now par-ticipate. About one-third of the examinationstaken are in mathematics and science."

Patterns of High School CourseOfferings and Enrollments

Along with family encouragement and expec-tations, preparation in high school mathematicsand science courses is vital to success in college-level science and engineering studies. Students'exposure to the traditional college-preparatorysequence of mathematics and science courses isrestricted by both the course offerings of theirschools and their willingness to take those courses.Minorities in particular often have less access toadvanced mathematics and science courses, be-cause school districts with high minority enroll-ments often cannot afford to offer many suchcourses. Offerings in rural and urban schools aregenerally more limited than those in suburbanschools.

Even when advanced courses are offered, stu-dents who could benefit from them often fail totake them. The point at which students are firstallowed to decide which mathematics or sciencecourses they are to take is widely believed to bean important fork in the educational pipeline forfuture scientists and engineers. Once students failto pursue the normal preparatory sequence ofcourses, it becomes hard for them to catch up.

Research indicates that there is a positive cone-lat!'"n between the number of advanced highschool mathematics and science courses taken andtwo educational outcomes: achievement testscores and students' intentions to major in scienceand engineering." Correlations between mathe-matics or science course-taking and achievementtest scores have been found in analyses of :ata

"Jay Mathews, "Tests Help 'Ordinary' Schools Leap Ahead,"Washington Post, May 14, 1987. In 1985-86, 7,201 schools partici-pated out of 30,000 secondary schools nationally Garfield HighSchool in Los Angeles, featured in the recent movie "Stand and De-liver," has become one of the top 10 schools in the Nation for thenumber of students who take and pass the advanced placement cal-culus test. Garfield is located in a poor and predominantly Latinoneighborhood

The correlation between outcomes such as these and the num-ber of mathematics courses tends to be stronger than that with thenumber of science courses

from both the NAEP mathematics assessment of1982 (for mathematics courses) and the 1980 HighSchool and Beyond (HS&B) survey of the sopho-more cohort (for both mathematics and sciencecourses)." These findings were sustained evenafter statistical allowance was made for student'srace, ethnicity, socioeconomic status, and earliertest scores. A strong correlation between highschool mathematics course-taking and the majorchoices of college students was found in an OTAanalysis of the 1980 HS&B cohort, even whenmany other factors were statistically con-trolled.'

Mathematics course-taking, presumably due toits sequential nature, appears to be more impor-tant for success in later science and engineeringstudy than science course-taking. The CollegeBoard recently noted in Academic Preparation forScience, a handbook that advises high schooleachers about what colleges would like them to

teach, that knowledge of scientific skills and fun-damental concepts will be more important to stu-dents than the number of high school sciencecourses they have completed."

It is difficult to be sure that the number of math-ematics and science courses taken is a principalinfluence in the decision to major in science orengineering.60 However, such courses do keepstudents in the pipeline.

Course Offerings and Enrollments

Students cannot take courses their schools donot offer. Only a few schools offer the comnlete

range of college-preparatory mathematics and sci-ence courses, a deficiency that has persisted formany years." Data on course offerings and en-rollments are plagued with inconsistencies. For ex-ample, courses with the same titles may havedifferent content while those with near-identicalcontent may have different titles. Inconsistenciesin data make the task of comparing schools,States, and years very difficult.

The most recent data on course offerings comesfrom the 1985-36 National Survey of Science andMathematics Education, sponsored by the Na-tional Science Foundation." This survey usedthe same course classification system as a 1977survey, permitting comparisons over time. Over90 percent of high schools offer at least algebraI, algebra IL and geometry, but advanced courseofferings are more limited. Only about 31 percentof schools offer a full calculus course (althoughsome senior-year mathematics courses may in-clude an introduction to calculus), and 18 percentoffer a course leading to the advanced placementexamination in calculus. In science, over 90 per-cent of high schools offer at least 1 year of biol-ogy and chemistry, and 80 percent offer 1 yearof physics.

Since 1977, mathematics course offerings haveincreased somewhat, trough the proportion ofschools offering calculus has remained constant.Science course offerings have increased slightly.In general, schools offer only one section of thesecollege-preparatory courses. It is not clear whetherthis outcome restricts or reflects demand for suchcourses. For example, 23 percent of U.S. highschools offer only one section of biology and 52percent offer only one section of physics.'

Some advanced courses are offered to high school students bycommunity colleges, but there are no national data on thisphenomenon.

"Weiss, op cit., footnote 15 No separate data are available onof'enngs and enrollments in laboratory courses; data on the amountof time different mathematics and science classes spend on labora-tory work is included in ch. 3.

"These data are confirmed by a National Science Teachers Asso-ciation survey. See Bill G. Aldridge, "What's Being Taught andWho's Teaching It," This Year in School Science 1986 The ScienceCurriculum, Audrey B Champagne and Leslie E Hornig (eds )(Washington, DC: American Association for the Advancement ofScience, 1987), ch. 12.

Data on course enrollments in ma' iiematics andscience indicate that the proportion of high schoolgraduates that have taken college-preparatorymathematics and science courses is very small(again see figure 2-3). While 77 and 61 percentof students took algebra I and geometry, respec-tively, only 20 percent took trigonometry andonly 6 percent took calculus. In science, 90 per-cent took biology, but only 45 percent tookchemistry I and 20 percent took physics. All ofthese proportions (except for calculus) representincreases from 1984."

Another analysis of the same database, whichused a somewhat different course classification,suggests that, even where courses are offered, en-rollments are low. About 80 percent of the stu-dents to whom the course is available enroll inalgebra I, 48 percent in geometry, and about 20percent in trigonometry. Similarly, in science,while almost all students to whom it was offeredtook biology, about one-third of the students withthe chance to take chemistry did so as did only10 percent of the students offered physics.'

More .ecent data from the 1985-86 NAEP inmathematics provide a "snapshot" view of enroll-ments in mathematics classes (see table 2-3, butnote that the classification of courses used herediffers from that used in other tables). These datasuggest that advanced course-taking in mathe-matics remains at a sme. proportion of 17-year-olds, although there were some very small in-creases between 1982 and 1986. Because these datawere taken from 17-year-olds, who have the sen-ior year of high school to go before graduation,they do not provide a complete picture of highschool course- taking.

These findings send a clear message: offeringsof pipeline mathematics and science courses areconstrained. More importantly, even when theyare offered, only tiny numbers of students takethem.

In general, Asianstudents are two to four times as likely to take advanced biology,chemistry, and physics courses than other minority students.

sequence of mathematics and science courses de-signed as preparation for college-level study in sci-ence and engineering, there is constant attritionin all categories of students. The attrition of fe-males, Blacks, and Hispanics is much greater thanthat of white males. Black and Hispanic 17-year-olds instead are more likely to report that theirhighest mathematics course was pre-algebra thanwhite students.

For example, while 5.6 percent of all high schoolgraduates in 1982 took calculus, only 2 percentof Blacks and 2.4 percent of Hispanics did. Thesituation showed little change by 1986, accord-ing to NAEP data, although Hispanic students haddoubled their participation in pre-calculus or cal-culus classes in that time. The gender difference,however, is not so pronounced: 5 percent of fe-males and 6.1 percent of males take calculus.

Another way of examining these data is in termsof the proportion of students by sex, race, andethnicitythat go on to take a higher mathe-matics or science course after successfully com-pleting the last one. Tabulations of these transi-tion percentages, based on a Department ofEducation analysis of the HS&B survey, appearin tables 2-6 and 2-7.

The data clearly show that females and minor-ities drop out of the normal sequence of courses.In mathematics, females drop out after taking al-gebra II and fail to take trigonometry; they alsoforgo physics after taking chemistry. Blacks andHispanics similarly fall out after trigonometry, al-hough fewer of them move from algebra to ge-ometry than do whites. These disparities arestronger among the "high-talent groups of thosewho earned As and Bs on the previous courses.

High-talent females drop out after algebra I, al-gebra II, and trigonometry. Very few high-talentBlacks take calculus, compared to whites, possi-bly indicating the paucity of calculus offerings inschools with high minority populations.Hispanics' persistence in science and mathematicscourse-taking is low throughout.

The data underscore the advantage studentsgain from attending suburban high schools ratherthan urban or rural ones. They also show a sig-nificant geographic disparity in persistence inmathematics and science course-taking. Persist-ence rates in the New England and Mid-A ianticregions are some 50 or more percent higher thanin West North Central, West South Central, andMountain regions. (See figures 2-6 and 2-7.)

These findings are supported by an analysis ofdata from the 1982 NAEP mathematics assess-

ment, which found that, regardless of curriculartrack, racial composition of the school attended,grade or achievement level, Black and Hispanicstudents lagged in enrollments in advanced math-ematics classes compared with their whitepeers."

Black enrollments in high school science coursesvary significantly according to geographic region,parental expectations (especially those of mothers),and high achievement in other subjects such asEnglish.' Black students in the Mid-Atlantic re-gions were more likely to take science courses,while those in the Pacific and the East South Cen-tral regions were least likely to take sciencecourses.

TRACKING AND ABILITY GROUPING

Ability grouping is practiced nearly universallyin American schools. Guidance counselors andteachers sort students by ability as early as thethird grade, using standardized tests and individ-

ual judgment. Students who display the conven-tional attributes of the potential scientist or engi-neer are encouraged to pursue the mathematicsand science courses that will prepare them for

these careers. Proponents claim that students in-terests are reinforced by exposure to those of theirsimilarly enthusiastic peers. Others are directedtoward other courses and careers. 4v hat we havehere is a double-edged sword.

The DoubleEdged Sword

Tracking or grouping is intended to help pre-vent the quick learner from trampling over theslow learner and the slow from delaying theprogress of the quick. In short, tracking is sup-posed to give al' students a fair chance (and helpteachers maintain control). Comparisons andlabels, however, are inevitable. Tracking is widelybelieved to both harm and help students' self-esteem, progress, achievement, socialization, andeducational and vocational destinations. Becauseits effects are varied and not readily measurable,it has been a very difficult issue for educationalreseal thers to study.

Many students' career options are narrowed bythis sorting. Those who fail to display the signsof early promise, and those whose home life oridiosyncracies place academic or social obstaclesin their paths, may find themselves shunted asidefrom the mathematics and science preparationthat makes possible further study of scienc. orengineering. Many of these students have the abil-ity and the desire to pursue these careers. Aboutone-quarter of those who go on to major in sci-ence or engineering were in a nonacademic trackin high school. Generally, their relatively poorntathematics and science preparation makes it dif-ficult for them to keep up in college, and they areat risk of attrition. Thus, ability grouping, if ap-plied too clumsily or rigidly, may lead to thewaste of talent.

Minority leaders, both within and outside theeducation community, have complained thattracking perpetuates racism. The evidence is thatthe practice is a structural impediment to students'progress to advanced study in science and engi-neering. Nevertheless, incoisistencies in defini-tions between surveys that include informationon tracking often yield misleading comparisons.In particular, it is not possible to state with anycertainty whether enrollments in the academic orgeneral tracks, either in total or by race or gen-

der, are declining through time. Figure 2-8, takenfrom High School and Beyond data, shows theproportion of students, by race and gender, thatwere enrolled in each high school curriculum trackin 1982, but these data are not necessarily con-sistent with other surveys." It is clear, however,that students are enrolling in courses in muchmore varied patterns than they used to: they fre-quently mix courses designed for the general,vocational, or academic track. To this extent, thestranglehold of tracking is loosening.

The principal objection to tracking or abilitygrouping is that it can become a self-fulfillingprophecy, changing the behavior of students,students' peers, teachers, and parents towardmembers of a particular group. For slow-trackedstudents the technique stifles aspiration by rein-

'Similar data are reported in Davis, op. cit , footnote 57, p 23,based on the National Assessment of Educational Progress (NAEP)1981-82 More recent data from the 1985-86 NAEP mathematicsassessment put the proportion of 17-year-olds enrolled in the aca-demic track at 52 percent, in the general track at 38 percent, and

the vocational track at only 10 percent. Dossey et al., op. cit ,

Science-intensive schools often have

forcing feelings of low st-tus and, worse, by feed-ing students' beliefs that they have been left be-hind and can never catch up. It deprives this groupof the stimulation provided by high achievers,which can help promote development of the be-havior and skills of learning. Some writers havesuggested that grouping and tracking is a primarymeans of maintaining the status quo, preventingthe upward mobility of the poor and minoritiesand excluding them from preparation ror profes-sional occupations such as science and engi-neering."

sophisticated, costly equipment.

Effects of Grouping PracticesFor all the controversy, research on the effects

of grouping is far from conclusive, even when ituses simple output measures such as achievementscores. This inconclusiveness might be taken asevidence that other important factors, such as stu-dents' socioeconomic status and teaching quality,are more important in predicting educational out-comes than the existence of tracking.

Research on the effect of ability-based group-ing practices in elementary schools has found thatgrouping makes little or no difference to the mostable students, but does have a considerable retard-ing effect on the less able students." A 1968

study of tracking in secondary schools by the Na-",onal Education Association found that for eachstudy that showed a gain in achievement scoresacross the ability spectrum another study showeda net loss. The exception was the lowest abilitylevel, which had uniformly slightly more lossesthan gains.'

To examine the effects of tracking on studentsintending majors in science and engineering, OTAused the High School and Beyond database." Inthe survey's random sample of about 12,000 highschool sophomores in 1980, 25 percent of thosestudents planning science and engineering majorsby their senior year and scoring above averageon the HS&B achievement test had been enrolledin the general and vocational tracks. Comparedwith their academically tracked peers, this groupwas of lower socioeconomic status and had aslightly lower average achievement test score. Bythe end of high school, they had taken about oneless mathematics course and their overall gradepoint average was about one-quarter of a pointlower. Their average SAT score was about 68points lower. They w ere less likely to go to col-lege and more likely t3 enroll in a junior collegethan members of the academically tracked group.Table 2-8 displays some characteristics of the twogroups.74

Other data indicate that academically tracked17-year-olds are more than twice as likely thanthose in other tracks to survive to algebra II inthe normal sequence of high school mathematicscourses, and about five times as likely to surviveto pre-calculus or calculus." Tracking does havesome positive effects on the academically trackedscience-intending stream, however, for it gener-ally ensures their continuing participation andpreparation in the science and engineering pipe-line, by increasing the probability that they willtake pipeline mathematics and sciemx courses.

courses is lost and their expectations are dulled.Nevertheless, the academic track is riot the rightplice for all students. A corollary problem is theearly age at which tracking occurs, putting manystudents at a considerable disadvantage when theyenter middle and high school. The need is for systerns to practice tracking efficiently but flexibly.

Science Education and Track-BustingIn the context of science and mathematics edu-

cation, the "efficiency" and "flexibility" of track-ing may be incompatible with the notionandtoday the more commonly heard prescriptionof "science for all."

Unless students very early acquire both a basicconceptual science vocabulary and a zest for

learning and problem solving, they are extremelyunlikely to take science coursesor to succeed ifthey do. . . . (Needed, then, is] a baseline sciencecurriculum that will provide all students with aconsistent and coherent overview and an in-tegrated body of knowledge during the elemen-tary and high school years."

What may appear to be "special pleading" for sci-ence and mathematics might then also be seen asone rationale for "track-busting." Put anotherway, a change in expectations of students' capa-bility will have to precede changes in both teach-Lig and learning.

Teachers and Teaching

I'll make a deal with you. I'll teach you math, and that's your language. Withthat you're going to make it. You're going to go to college and sit in the firstrow, not in the hack, because you're going to know more than anybody.

America's schools will shoulder important newresponsibilities in the years to come. Well-educated workers of all kinds are looked on in-creasingly as economic resources: Schools, par-ents, communities, and government at all levelsare expected to educate a population that willgrow more ethnically diverse in an economy thatis increasingly reliant on science and technology.International competition will be invoked as aspur to excellence. The need for full participationby minorities and females will become a chronicnational concern. Nowhere will these pressuresbe felt more strongly than in the education of sci-entists and engineers. The pressures, in short, willfall squarely on mathematics and science teachers.

It is a burden the teaching profession, togetherwith school districts and teacher education insti-tutions, is ill-equipped to meet. Fears of shortagesof mathematics and science teachers now and inthe future abound, and there is great concernabout the poor quality of teacher training and in-service programs. The quality of teaching, in thelong run, depends on the effectiveness of teachers,the adequacy of their numbers, and the extent to

which they are supported by principals, curricu-lum specialists, technology and materials, and thewider community. Teachers of mathematics andscience need to be educated to high professionalstandards and, like members of other professions,they need to update their skills periodically.

At the same time, research on the teaching ofmathematics and science suggests that some tech-niques not widely used in American schools canimprove achievement, transmit a more realisticpicture of the enterprise of science and mathe-matics, and broaden participation in science andengineering by females and minorities. These tech-niques have been adopted slowly. Practical ex-periments and class discussion, for example, areslighted by many teachers in favor of lectures,book work, and "teaching to the test." Smallgroup learning, in which students cooperate to ac-complish tasks, is also rare, although a few Statesare making room for it in their educational pre-scriptions. Teachers themselves seldom have op-portunities to exchange information with theircolleagues in other schools. Increasing such oppor-tunitiesfor teachers and students alikecouldhave significant effects on, amo lg other things,the size and quality of the national science andengineering talent pool.

that a good mathematics and science teacher hason a student's propensity to major in science andengineering cannot easily be evaluated quantita-tively.

There are two major, and related, challengesthat affect mathematics and science education: thefirst is the potential for a shortage of mathematicsand science teachers, and the second is the needto improve the quality of teaching. 'ome fear thatStates and school districts will simply lower cer-tification and hiring criteria standards in the faceof possible shortages. Shortages are likely to causeproblems in certain States and school districts,especially in the supply of minority mathematicsand science teachers. But improvilg the qualityof mathematics and science teaching is as impor-tant as addressing shortages.

Science and mathematics teachers are part ofthe entire teaching work force. In many ways,there are few differences between mathematicsand science teachers and teachers of other sub-jects. Each are covered by the same labor con-tracts, belong to the same teacher unions, sharethe same working conditions, and are normallypaid the same salaries.' Similarly, mathematicsand science teachers share in the low esteem with


NY: Basic Books, 1988) Also see Daryl E Chubin et at , "Scienceand Society,"Issues in Science & Technology, vol 4, summer 1988pp. 104-105

'An ongoing controversy related to the entire teacher work forceis the role of unions Some people think that teacher unions, throughtheir sometimes stubborn resistance to change, are the cause of manyproblems in education. These problems include the difficulty in fir-ing poor teachers and in staffing "difficult" schools, the devotionto the "seniority" principle (rather than teacher's merits) shown inallocating salary increases, and the potential barrier to meaningfulreforms erected by the granting of "tenure" to teachers Others thinkthat teacher unions can be of great help in providing a single pointof negotiation for many aspects of teachers' working lives and con-ditions, forging teachers into a profession based on common, self-specified norms and goals of conduct, and encouraging teachers tobecome more reflective of their tasks There are two main teacherunions, the American Federation of Teachers and the National Edu-cation Association Their leaders are 'risible in the national debateon reforming American education, of ten calling for greater publicspending on education, and their positions have frequently been atodds with those of the U.S. Secretary of Education There is no in-dication that the form aid extent of union activity in mather.,atics2 d science teaching is any dfferent from that for teaching as a whole(although there are special professional associations of such teachers,such as the National Science Teachers Association and NationalCouncil of Teachers of Mathematics). The positive and negative im-pacts of teacher unions are not considered further in this report

which many Americans hold teaching and pub-lic education in general.'

In mathematics and science teaching, there areimportant differences between teacher prepara-tion and assignments in elementary schools andsecondary schools. Elementary teachers teachmany unrelated subjects, while secondary teachersconcentrate on particular subjects, such as math-ematics or science (although many do both, orteach several different science fields). Accordingly,most elementary teachers are not specialists in anysubject. They normally hold baccalaureate degreesin education and have had relatively little scienceand mathematics coursework (if any) at college.Most secondary teachers, however, have takenmany mathematics and science courses in college;some have an undergraduate degree in these dis-ciplines.'

The Possibility of Mathematics andScience Teacher Shortages

Many observers are worried about possible fu-ture shortages of teachers, and, reportcdly, insome geographic areas it is already difficult to hireadequate numbers of mathematics and scienceteachers.' It is widely believed that shortages of

'For example, surveys show that the percentage of Americansthat would like their children to become public school teachers hasfallen from 75 percent in 1969 to 45 percent in 1983. In a similarsurvey in 1981, Americans ranked clergymen, medical doctors,judges, bankers, lawyers, and business executives as being in profes-sions with higher prestige and status than public school teaching.Only local political officeholders, realtors, funeral directors, andadvertising practitioner, were ranked lower Stanley M Elam (ed.),The Phi Delta Kappa Gallup Polls of Attitudes Toward Education1969-1984 A Topical Summary (Bloomington, IN.

teachers of all kinds are imminent due to an in-crease in the numbr of teachers approachingretirement and a decrease in the number of col-lege freshmen planning to become teachers dur-ing the last decade. In the aggregate, these trendsaffect the size of the teacher work force. But itis events in the middle stages of teachers' careersas well that predict future supply and demand.For example, many fully qualified teachers leavethe profession (perhaps to start families), and maybe lured to return to schools in due course.

To estimate whether there will be a shortage,and what its effects might be, it is necessary tohave data on the future work plans of the exist-ing teaching work force, the rates of entry to andexit from it, the extent to which these rates changein response to market signals, and what measuresmight reduce the effect of any shortage. A con-

ceptual model of entry to and exit from the teacherwork force is depicted in figure 3-1.

Current estimates of the rates of entry to andexit from the teaching work force are very poorand often inconsistent! It is not possible, therefore, to determine with any certainty whether

there will be a shcrtage, what its effects might be,or what the special aspects of the problem willbe for mathematics and science teaching. Someaspects include:

How intensified competition for new scienceand engineering baccalaureates will reducethe already small incentives for new gradu-ates to consider mathematics and scienceteaching careers.The extent to which mathematics and scienceteachers who are already qualified but work-ing in other occupations could be lured backto classroom teaching in response to highersalaries or changes in working concIP-ions.The extent to which working and retired sci-entists and engineers could be retrained to en-ter the teaching work force. Several programsare attempting to retrain such people.How attrition of existing teachers (currentlybetween 5 and 10 percent annually) can bereduced.' (See box 3-A.)The extent to which changes, such as the in-troduction of less restrictive certification re-c.-, virements, the use or uncertified teachers,arid i.he assignment of existing teachers outof their main teaching fields to teach mathe-matics and science classes, could covershortages.How the use of part-time teachers, masterteachers, or teaching assistantships couldcompensate for any shortages.The extent to which greater use of technol-ogies, including computers, video recorders,and distance learning techniques, could re-duce the need for mathematics and scienceteachers.'

Vi survey of teacher attrition, based on followups of the Na-tional Longitudinal Survey of 1972, is in Barbara Heyns, "Educa-tional Defectors A First Look at Teacher Attrition in the NLS-72,"Educational Researcher, April 1988, pp 24-32. One surprising find-ing of this and other studies (such as the U S Department of Edu-cation's Survey of Recent College Graduates) is that a large num-ber of those who complete teacher training programs never, in fact,teach In the 9 years between 1977 and 1986, one-quarter of thosequalified never taught, and 40 percent of those who became newlyqualified teachers in 1983-84 had not become teachers by 1985 Seealso Richard J.

Box 3-A.Reasons Why Physics TeachersLeave High School Teaching

A 1983 survey reported some of the reasonswhy physics teachers leave teaching.' Thosewith a graduate degree in physics can readily findwell-paying jobs in industry; either they neverenter the teaching profession or they hastily de-part. In general, the survey found, physicsteachers leave for the following reasons:

Instructional laboratories are poorlyequipped and budgas are inadequate formaking improvements.It is difficult to remain professionally active.There are seldom funds for teachers to at-tend professional meetings, to keep up-to-date with scientific literature and advances,or to meet and share experiences with teach-ers in other schools. This feeds a sense ofisolation.Accountability to local, State, and Federalbodies has multiplied both teacher paper-work and administrative duties.There is a lack of identification by mostschool administrators with the problemsthat interfere with quality science teaching.School administrators, the survey reports,are often not interested in improving scienceteaching.There is a lack of respect within the localcommunity. Tike teachers of all subjects,physics teachers are often criticized in schoolboard meetings as being greedy and ineffi-cient, particularly when funding decisionsare made.Voters do not support the schools, as evi-denced by the willingness to vote downschool bond issues in the early-1980s, evenat the expense of reductions in the size andquality of the teaching work force. Thisstrong pressure to cut taxes is especially evi-dent in smaller communities whose demo-graphics favor needs other than those of thestudent population.

'For reasons why physics teachers leave teaching, see BeverlyFearn Porter and William H. Kelly. "Why Physicists Leave Teach-ing," Physics Today, September 1983, pp. 32,-37. Also see AmericanAssodation of Physics Teachers, The Role, Education, and Qualifi-cations of the High School Physics Teacher (College Park, MD:AAPT Committee on Special Projec. for High School Physics, 1986).As this technical memorandum went to press, the American huh-tute of Physics released a new report, Michael Neuschats and MaudeCovalt, Physics in the Schools: Findings From the 198647 Na-tionwide Survey of Secondary School Teaches of Physics (New York,NY: American Institute of Physics, 19$1).

Some secondary school principals are havingdifficulty hiring science teachers and (to a lesserextent) mathematics teachers. The 1985-86 Na-tional Survey of Science and Mathematics Edu-cation found that 70 percent of secondary schoolprincipals said that they were having difficulty hir-ing physics tethers, 60 percent were having dif-ficulty with chemistry and computer scienceteachers, and over 30 percent were having diffi-culty locating biology and life sciences teachers.The survey found that few schools had incentiveprograms to attract teachers to shortage fields;retraining programs are the more commonmethod of supplying shortage fields.'

After years of declining interest among collegefreshmen in becoming teachers, there has been anupturn since 1986." A 1985-86 survey estimatedthat about 20 percent of science and mathematicsteachers are expected to retire in the next dec-ade." The result of these opposite trends is any-body's guess, so speculations abound.

Salaries

Many policymakers and educators point to thegenerally low level of teachers' salaries and claimthat neither the number nor the quality of math-ematics and science teachers can be improved untilthese salaries are increased substantially." In

ables school districts to provide instruction from one site to manysitesbut teachers are not replaced Instead, these distance learn-ing projects aggregate sparsely populated classrooms of two or threestudents to more "regular" sized classrooms (Linda Roberts, Officeof Technology Assessment, personal communication, September1988)

fact, teachers' salaries are rising. In real terms,average annual public school teacher salaries fellduring the 1970s by about 10 percent from theirall-time high in the early 1970s. By 1984-85, theyhad risen to just under what they were in 1969-70. The mean tea:her salary in 1986 was about$25,000, but with large variations among theStates.14 The effects of these increases on teachersupply and quality, which take time to show up,may yet be very positive. Already, there is someincreased interest among college freshmen inteaching careers.

The attractiveness of different occupations tonew college graduates is shaped by the immedi-ate starting salaries as well as prospective long-term earnings. Students with considerable debtsfrom their baccalaureate education, it is argued,need a substantial source of income to start pay-ing off these debts. Starting teaching salaries havecons ,cently been lower than those in other profes-sions, and have not increased as rapidly duringthe last decade. (See figure 3-2.)

A particular controversy for mathematics andscience teachers is whether they should be paidmore than other teachers in order to attract peo-ple to fill shortages. A recent survey indicated thata majority o; secondary mathematics and scienceteachers would support differential pay of thiskind, and many principals are also in favor of this.Support among those who teach mathematics andscience at the elementary level is weaker. Tradi-tionally, teacher unions have argued that teachersshould be paid the same, regardless of their sub-ject specialization.'

Minority Teachers

Because of the declining proportion of Blacksand Hispanics entering college and because of theexpanded career options now open to them, the

Rumberge- finds that the disparity between engineering and math-ematics/science teaching salaries has some effect on teacher short-ages and turnover, the chspality, however offers tar less than a com-plete explanation

'For example, between 1969-70 and 1084-85, Alaska teacher sal-aries dropped by 34 percent in real terms, whereas those in Wyo-ming and Texas rose by 14 percent U S Department of Fducation,Office of Educational Research and Improvement, Center for Edu-cation Statistics, Digest of Education Statistics 1087 (Washington,DC U S Government Printing Office, May 1987), tables 51-53

number of minorities electing teaching careers isdeclining. There are, in the first instance, com-paratively few Black or Hispanic mathematics andscience teachers. Data from a recent st. vey (seetable -1) indicate that the majority of Blackteache:., are in the elementary grades; only 3 per-cent and 5 percent, respectively, of mathematicsand science teachers in grades 10 to 12 are Black.Only 1 percent of teachers of 'loth these subjectsare Hispanic. For now, the p portion of minor-ities in the teaching force is increasing slightly,but several commentators warn of future short-ages of minority teachers, particularly in mathe-matics and science. Such a shortage poses particu-lar problems to schools with high minorityenrollments, denying minority children role

Certification and Misassignment ofMathematics and Science Teachers

Each State sets specifications, designed to en-sure a minimum level of professional competence,for the academic preparation of teachers. Thesespecifications, which take the form of require-ments for a minimum number and combinationof college-level courses in mathematics, science,and education, are enforced through certificationand periodic recertification of teachers. Certifi-cation requirements vary considerably from Stateto State (see table 3-2), and there are differencesin the extent to which they are enforced. TheStates may also require examinations, such as theNational Teachers' Examination, for either initialcertification or later recertification."

teachers, in particular, appear to be teaching sub-jects that they are either not licensed or not qual-ified to teach. A 1986 survey of 39 States (enroll-ing 28 percent of the student population) estimatedthat between 6 and 15 percent of all science teach-ers were uncertified in the field they were hiredto teach. Biology had the lowest proportion ofuncertified teachers, while earth and general sci-ence had the highest. About 8 percent of mathe-matics teachers were uncertified in that field.'The proportion of uncertified mathematics andscience teachers was greacest in the Southeastgion of the country. A 1985-86 survey indicatesthat as many as 20 percent of science teachers ingrades 10 to 12 are not certified to teach thecourses they are teaching: 4 percent are not cer-tified at all, 6 percent have provisional certifica-ion, and 5 percent are certified in other fields (theremainder are presumably those certified in onescience subject but teaching another). This samesiirvey found that, of teachers of mathematics ingrades 10 to 12, 4 percent were not certified atall and 4 percent had only provisional certifica-tion, while 10 percent were certified in fields otherthan mathematics. In total, 14 percent of theseteachers were teaching courses that they were un-certified to teach."

National dc.ta from the National Science Teach-ers Association (NSTA) indicate that the notionthat a high school science teacher teaches only onescience is increasingly a myth. And many scienceteachers teach mathematics or nonscience subjectsas well. On average, al-,out 8 percent cf the courseassignment of secondary science teachers is inmathematics, and 5 percent is in nonscience sub-jects. For example, about half of the teaching loadof Caemistry teachers is :it chemistry, 12 percent

Issue such certification, States and school districts have an easy wayto rectify any concerns about the number of uncertified teachersin the classroom.) Princ pals reportedly prefer often to retain exist-ing uncertified teachers in classes where they have developed rap-port with the class than introduce new, inexperienced, hit fully cer-tified teachers who would have much more difficulty teaching theclass

'Joanne Capper, A Study of Certified Teacher Availability inthe States (Washington, DC. Council of Chief State Schoo: Officers,F'bruary 1987) These data are drawn from State needs asse' sments,mandated under Title II of the Education for Economic Security Actof 1984, the data analysis was fundeu by the National Science Foun-dation

in biology, and 15 percent in physics and generalphysical science."

This pattern :s reflected in the teaching of allsubjects at the secondary level. The National Edu-cation Association estimates that 83 percent of allsubject specialist secondary teachers devote alltheir teaching time to teaching the field that wastheir college major; 7 percent spend between 50and 100 percent of their time in that field; andonly 10 percent spend less than 50 percent of theirtime teaching in that field."

While States condemn teaching without ade-quate certification, critics of the system of certifi-cation note that States tacitly condone it by per-mitting waivers of requirements and by failing toenforce certification requirements.' To the ex-tent that shortages exist, States, school districts,or principals must choose whether it would be bet-ter to have a poorly qualified teacher teaching ascience class than to have no teacher and no classat all.

A number of States have developed alternativecertification routes for mature entrants to theteaching profession, particularly those who arealready qualified scientists, engineers, or techni-cians. These programs focus particularly on re-cruiting mathematics and science teachers. A re-cent study estimates that there are 26 suchprograms nationally, and some have attractedFederal funding.24

These 1:ograms look promising, and could beexpanded in the interests both of the quantity andquality of the entry-level science and mathematicswork force.

Box 3-B.Mathematics and Science Relicensing BoardDuring the summer of 1984, the New York City Board of Education decided tc, retrain teachers ofother subjects to teach mathematics and science.' The board realized that urban schools were most vul-nerable to any future teacher shortage, because the staffs of such schools are typically older than their subur-

ban counterparts and because teachers prefer to work in suburban school systems. On average, the proportionof New York's teaching force that will retire soon is about twice that of the national teacher work force.The Mathematics and Science Relicensing Board's task is to "re-tool" teachers of subjects such as Engliehand history in which there is a teacher surplus, and, by Apri11987, had succeeded in awarding 400 licensein mathematics and science. These recerthied teachers are primarily female and minority; data frcan 1985indicate that 61 percent of program participants were women and 45 percent were Black or Hispanic, per-centages that were considerably higher than those of the teaching force of New York City as a whole (ap-proximately 22 percent of secondary school teachers of all subjects are members of minority groups and50 percent are female). The participants think that their new licenses will make them more mobile andgive them the challenge of working in a new field.The recertification program was free to the teachers, and took place after hours and in the summerat nearby universities and colleges. These classes were arranged especially for the Relicensing Board, andcost between $45 to $70 per credit, depending on the class and university. The academic program is similarto an undergraduate major, and teachers can be simultaneously certified in different subjects, as well asat different levels. After coursework is completed, candidates must pass a city-wide examination, and, afterpassing, take a probationary position as a teacher in the new field. After 2 years, tenure is reviewed. Ifgranted, the licensees are certified both for course and probationary period completion. Seminars and tutorialsare also offered to assist in preparation.The program benefits from its cooperative model; it is the only one in the United States that bringstogether so _ny different institutions and groups with an interest in staffing city classrooms. Funds comefrom the city, advertising is by courtesy of the United Federation of Teachers, the Board of Education ap-proves the program, the Division of Curriculum and Instruction establishes and manages the program,and 11 universities and colleges take part. Everyone benefits, particularly the academic institutions thathave a strong interest in improving the level of preparation of their future students.An important benefit of the board has been that the large number of Black, Hispanic, and female teacherstrained through the program has increased the interest of their minority and female students hi mathematicsand science. An evaluation of the program is in progress.

THE PROFESSIONAL STATUS OF THE TEACHING WORK FORCEConcern about teacher shortages and quality

comes at a time when the teaching profession asa whole feels embattled and undervalued, but alsorecognizes its key role in education and in edu-cation reform. Seemingly endless commissionreports have cited the need to give greater status,more recognition, and higher salaries to teach-ers." Although teachers aspire to belong to aprofession, few feel that they truly do. Manyargue that administrators and school boards, notteachers, define standards of conduct in schools,teaching methods, and curricula. Teachers areconstrained by many rules and regulations, manyof which conflict with each other and which,taken together, sap the enthusiasm of many teach-ers. In some ways, the process of increasing re-quirements and paperwork is a kind of "de-skill-ing" of the teaching work force: the skill ofteaching is removed from teachers and given tothose who make and enforce the "rules.""

One way of redressing the balance is to giveteachers more say in setting the professional qual-ifications and standards for membership in theteaching force. The recommendation of the Car-negie Task Force on Teaching as a Profession fora national certification board is being imple-mented; its first members were nominated in May1987. Eventually, such certification might replaceState certification. Parallel moves are afoot in the

mathematics and ?--cienct teaching profession. In1984, NSTA estimated that about 30 percent ofall secondary mathematics and science teacherswere either "completely unqualified or severelyunderqualified" to teach these subjects." NSTAlaunched its own certification program for scienceteachers in October 1986. The fact that many"single-subject" teachers teach a good deal of othersciences and mathematics has led NSTA to de-vise a iwo -track secondary certification program:one for general science teaching, the other forsingle-subject science teaching. Currently, fewerthan one-third of the science teaching force wouldmeet NSTA's standards? The guidelines of bothNSTA and the National Coilncil of Teachers ofMathematics (NCTM, set in 1981) are listed in ta-ble 3-3.

The Quality of Mathematicsand Science Teachers

Mathematics and scienct teacher quaiity is noteasily measured.' There are three related andcommonly used indicators of teacher quality: pos-session of State certification, conformity to guide-lines established by such bodies as NSTA andNCTM, and the amount of college-level course-work that teachers have had (on which the othertwo indicators are based). Many commentatorscaution against equating course preparation withteacher quality. Nevertheless, reliable data existonly for this measure and it is the one used here,along with teachers' own perceptions of their con-fidence and abilities.3'

least a master's degree." A 1985-86 surveyfound, in grades 10 to 12, that 63 percent of sci-ence teachers and 55 percent of mathematics

"National Education Association, Status of the American Pub-lic School Teacher 1985-So (West Haven, CT 1987), tables 1-2

teachers had earned degrees beyond the baccalaur-eate. The same survey also found that 40 percentof mathematics teachers hid degrees in mathe-matics, and 60 percent of science teachers haddegrees in a science field." By contrast, only 1to 2 percent of mathematics and science teachersat the elementary school level had degrees in thesefields.

The National Survey of Science and Mathe-matics Education gathered its data from about4,500 teachers from all grades in 1985-86.34 Thesurvey showed that many elementary mathe-matics and science teachers have taken very fewcollege-level courses in these subjects, while sec-ondary teachers of these subjects have much moreextensive preparation. (See tables 3-4 and 3-5.)

The survey indicated that over 85 percent ofelementary science teachers have taken at least onecourse in methods for teaching elementary schoolscience, and about 90 percent have taken at leastone college-level science course (typically biology,psychology, or physical science)." However, al-though 90 percent of elementary mathematicsteachers have taken at least ^^e course in methodsfor teaching mathematics .dy about 40 percenthave taken at least one college-level mathematicsclass. Most have taken instead mathematicscourses especially designed for elementary math-ematics teachers. Elementary school teachers feelgood about mathematics; 99 percent feel well-qualified to teach it, compared to 64 percent whofeel well - qualified to teach science, particularlyphysical science. About 80 percent if elementarymathematics and science teachers enjoy teachingthese subjects. Inservice training is also not reach-ing many elementary teachers; more than 40 per-cent report that they have had no inservice train-ing in the last year, and another 25 percent havehad less than 6 hours in total during the year.

About 90 percent of junior high and high schoolmathematics and science teachers have taken atleast introductory biology in college, over 70 per-cent have taken general physics, 50 percent geol-ogy, and 80 percent general chemistry. Many have

Of mathematics teachers in grades 7 to 12, over80 percent have had at least college algebra,trigonometry, or elementary functions, and about70 percent of them have had calculus. Still, about7 percent feel inadequately qualified to teachmathematics, and over 25 percent had not takena college course for credit in the last 12 years (55percent during the last 5 years). Over 50 percenthave not had more than 6 hours of inservice edu-cation during the last year. This translates intoa lack of confidence in teaching skills. About 20percent of elementary teachers felt very well-qual-ified to teach mathematics and science respec-tively; another 20 percent felt they were not well-qualified to teach science:7

Options for Improving the Quality ofMathematics and Science Teachers

More States indicate shortages of quality sci-ence and mathematics teachers than of teacherswith appropriate qualifications to teach these sub-jects. Credentials are not enough. Most Stateshave attempted to alleviate their shortagesthrough higher teacher salaries, and some also usespecial loan and staff development programs formathematics and science teachers in order to re-tain good teachers and retrain teachers from otherfields. Iowa, for example, grants loans to currentteachers to upgrade their skills in mathematics andscience teaching, and sponsors summer traininginstitutes. Idaho uses Title II funds to providescholarships to potential science or mathematicsteachers who want to be recertified in these sub-ject areas.

At least 26 States have inservice teacher train-ing programs for science and mathematics instruc-tors, most involving loans or E holarships topromote additional coursework. The TeacherSummer Business Training and Employment Pro-gram in New York partly reimburses industry forscience. mathematics, computer, or occupationaleducation teachers employed by business and in-dustry during the summer.

About 10 States now offer alternative certifi-cation programs for prospective mathematics andscience teachers. For example, Utah awards "Emi-nence Certificates" to qualified professionals suchas engineers and doctors, which allows them toteach up to two classes per day. Other, more inno-vative means of recruiting new mathematics andscience teachers include hiring teachers from over-seas. (California and Georgia recruit science andmathematics teachers from the Federal Republicof Germary, and Kansas City, Missouri, has im-ported teachers from Belgium.) Florida holds anintensive teacher job fair each June, called "TheGreat Florida Teach-In," designed to attract andplace new teachers.

The quality of the mathematics and scienceteacher work forces can be improved before peo-ple enter the classroom as teachers (generally re-ferred to as preservice) or when they are activelyteaching (inservice). Given the low labor turnoverof the teaching force, between 5 and 10 percenteach year in all subjects,38 the way to upgradeteaching quality is via inservice programs. Yetthere is considerable national anxiety about theperceived deficiencies of preservice teacher prep-aration in all disciplines."

Preservice Education

While many talented people do become t'ach-ers, it is sometimes suggested that teacher educa-tion is not challenging.4° Critics further chargethat teacher preparation programs fail to make

°ILitional Science Board, op cit., footnote 6, p. 25. As BernardR Gifford, Dean of tne School of Education, University ofCalifornia-Berkeley, puts it "What s wrong with schools and de-partments of education today is very simple. Education suffers fromcongenital prestige deprivation." See Anne C Roark, The Chet,of Academe: Few Takers (Teacher Colleges)," Los Angeles T .Mar 13, 1988, p. 6. A new book dissects the origins and repL.cus-sions of this prestige deprivation on university campuses See Goaldine Joncich Clifford and James W Guthrie, Ed School A Brieffor Professional Education (Chicago, IL University of Chicago Press,1988)

effective links between courses on mathematicsand science and those on education, and there-fore, teachers are unable to convert courses onclassroom teaching techniques and theories oflearning. In addition, such courses convey a sim-plistic view of science as a monolithic collectionof facts, embodied in enc -mous textbooks, giv-ing students a false impression of the nature ofscientific inquiry.

Teachers agree that experiments and hands-onactivities are more effective than book work, butfeel the overriding need to cover material in en-cyclopedic fashion. The extensive use of factualrecall tests creates incentives to cover the content,rather than process, of the subject matter. Thus,teacher preparation may be more telling than theirclassroom practice. In college, prospective teach-ers model their attitudes and teaching practiceson those of their college professors and, indeed,on their own school teachers. They employ theteaching techniques, such as lectures and rotememorization, that they were either forced to suf-fer or benefited frlin when they were students.School district cum culum guides and testing fuelteachers' reliance on tools for covering conceptsand facts, one by one, without drawing links andbrightening the big picture of science. Preferencemay signal a lack of alternatives; teachers mayhave neither the tools nor the opportunity to be-come comfortable with them to change their ap-proach.


Most reports on reforming education single out theimportance of improving the status, appeal, and quality of

the teaching profession.

68

There is still no complete model of what themathematics and science teacher curriculumshould be. Simply requiring more mathematicsand science courses for certification will not auto-matically improve teacher quality, given the con-tent of these courses and the way they are oftentaught. The National Science Foundation (NSF),for example, has recently begun a program to de-velop new models for preservice preparation ofmiddle school teachers.

One particular controversy in mathematics andscience teacher education is whether futureteachers should be expected to have a baccalaure-ate degree in a discipline plus some professionaltraining. At present, many teachers at the elemen-tary level earn baccalaureate degrees in education,but 97 percent of elementary mathematics teachersand 95 percent of elementary science teachers havea degree in subjects other than science or scienceeducation. At the high school le\ 1, however, 40percent of mathematics teachers and 60 percentof science teachers have a degree in those subjects,and another 36 and 24 percent, respectively, havea degree in mathematics and science education ora joint de -ee in a mathematics and science sub-ject and . ..ence and mathematics education.4'

Several groups that have studied the future ofthe teaching profession in the current reformmovement ha; looked at this issue. The HolmesGroup (an informal consortium of educationdeans in research universities) has attached pr;-ority to upgrading elementary and secondaryteachers' specific knowledge by insisting that theyhave a baccalaureate degree in a subject area. Theiic!mes Group has also called for much greateruse of specialized teaching, and for more subject-iirtensive preparation of those teachers 42 So far,only Texas has changed its certification require-ments in this way; after 1991, new entrants to the

"Weiss, op cit , footnote 10, table 45'The Holmes Group, Tomorrow's Teachers (East Lansing, MI

1956). See also Lynn Olson, An Overview of the Holmes Group,'Phi Delta Kappan, April 1187, pp 619-621 Subject- intensive prep-aration may be unrealistic for elementary school teachers Just askan elementary teacher what she teaches and the response will be"children" or "grade n", a secondary school teacher will respondwith "science" or "math Most parents would nrobably take' com-fort that their child is being taught by someone who believes theirprimary allegiance and responsiblity is to children, not subjects(Shirley Malcom, American Association for the Advancement ofScience, personal communication, August 1988)

profession in Texas will have to have both a dis-ciplinary degree and no more than 18 course-hours of education courses."

Currently, NSTA and NCTM both require con-siderable amounts of subject-specific courseworkof applicants for their own certification programs.Content, rather than titles, of the courses futureteachers take is essential; there is a large grey areathat colleges universities can exploit in spe-cific subject areas (such as mathematics educa-tion). But the long-term trend is to emphasize spe-cific skills for specific subjects rather than generic"education" courses.

Preservice education of science and mathe-matics teachers presents a surfeit of issues and littleconsensus over how to address them. College de-partments of science and mathematics preparetheir students to become scientists or engineers,not teachers of these stLjects. Few, if any, coursesare offered th it give prospective teachers a senseof what scientists do or how science and mathe-matics impact on IA orkday activities and societalproblems. Can teachers be blamed for not tak-ing what is not offered, or for not executing intheir classrooms what they were unable to experi-ence as students (i.e., the apprenticeship role)?This "no-fault" explanation distributes the respon-sibility for the perceiveci shortcomings of the neo-phyte teacher." It also transfers part of the bur-den to inservice training.

The Importance of Inservice TrainingOnce teachers are in place, as in any profes-

sional work force, they need periodic updatingand tirne to consider how they could do their jobsbetter. f c present, inservice training is also neededto remedy the inadequacies of many teachers' pre-service preparation. A recent survey indicates thatthere has been an increase in the amount of in-service training taken during the school year,which has come at the expense of college-level

course-taking on weekends and during vacations.Three-quarters of teachers now report taking in-service courses during the school year, comparedwith 59 percent 15 years ago "

Another recent survey found that most math-ematics and science teachers, at all grade levels,had spent less than 6 hours on inservice educa-tion in 1984. (See figure 3-3.) Secondary teachershad spent more time on inservice education thanelementary teachers; over 10 percent of mathe-matics and science teachers in grades 10 to 12 hadtaken more than 35 hours of inservice educationduring the last year."

A leading policy issue is who should be respon-sible for inservice education. As employers, school

districts should b primary supporters of sucheducation, but it is among the first budget itemsto be cut in periods of austerity. In practice,teachers are often expected to arrange and payfor such education themselves. While many teach-ers do participate, commentators suggest thatthere is a large pool of mathematics and scienceteachers who are never reached."

Perhaps most lacking is a national commitmentto the continuing education of science and math-ematics teachers. Such education comes in manyforms, including multiweek full-time summer in-stitutes, occasional days to attend professionalmeetings, and provision of relevant research ma-terials and work sessions on how to translate theseinto practice. In s, )me areas, contacts betweenschools, school districts, scientific societies, Stateeducation agencies, and universities exist and arefruitful, but other areas are devoid of this sup-port. Teachers need much better information thanthey are getting, particularly because of rapidchanges in science and educational technology."

The Federal Government supports inserviceteacher education through both Title II of the Edu-cation for Econoi sic Seci,-ity Act program of theDepartment of Ectucati m and the NSF TeacherEnhancement Program. In the 1960s, NSF fundeda large program of summer and other institutes,based at universities, for mathematics and scienceteachers. (See ch. 6.) Generally, these institutesseemed to have had poiitive effects, and their per-ceived excesses (for , xample, an emphasis onknowledge of science content) could be reducedwere the concept to be revived. The bulk of thefunds in the previous program went to collegesand universities; local school districts could nowbe partners in such education.

Another important Federal role could be a re-gional system of mathematics and science educa-

Conclusions on Mathematics andScience Teacher Quality

The effect that good mathematics and scienceteaching has on students' propensity to major in

79

science and engineering is not readily measured.Schools must lead, inform, and interest studentsin mathematics and science, and teachers are thefront line. At the moment, many only inform andsome probably dull students' interest in mathe-matics and science. On paper, the teaching profes-sion is relatively well-qualified, and has had a sig-nificant (and increasing) amount of teachingexperience. The teaching force needs inserviceeducation, however; this presents an enormoustask. School districts, States, and teachers (whohave already ha 3 and paid for a college educa-tion) are unlikely to undertake this alone. Untilschool districts and States make mathematics andscience teacher quality a high priority, student in-terest in and preparation for careers in science andengineering are not likely to flourish.

TEACHING PRACTICES AND STUDENT LEARNING

There are several teaching techniques that couldbe used more widely to boost both students' learn-ing and interest in mathematics and science. Inrecent years, a considerable body of literature on"effective schools" has been assembled. This re-search has been synthesized for teachers, prin-cipals, and administrators to read." There is anurgent need to write and disseminate more syn-theses of this kind in other educational researchareas."

One technique in both mathematics and scienceeducation is experimentation. Experiments, espe-cially when they are related to physical phenom-ena that students encounter in everyday life, arewidely credited with improving students' attitudestoward and achievement in science. According toa recent survey, teachers think that hands-on sci-ence is an effective teaching method, yet few useit." If experiments are prui;2rly planned, stu-dents learn that science advances by curiosity,

manipulation, and failure. Mistakes are a normalpart of science. The use of textbooks that empha-size the "facts" discovered by science, on the otherhand, reinforces the popular (but mythical) viewthat science is a logical, linear process of ac-cumulating knowledge.

Science experiments raise achievement scoresand can often trigger positive attitudes toward sci-ence among students. Nevertheless, concernsabout the cost and safety of experiments inhibitthe amount of laboratory work offered, as do thelimited facilities many schools have for this kindof teaching. Experiments require equipment andare more costly than lectures."

Incl'cations are that the amount of hands-onmathematics and experimental science is diminish-ing. (See figure 3-4.) A recent survey found thatthe percentage of science classes in 1985-86 usinghands-on activities has fallen somewhat since 1977at all grade levels. Hands-on activities were mostcommon in elementary classes; only 39 percentof science classes in grades 10 to 12 used the tech-nique (down from 53 percent in 1977). In mathe-matics, there have been similar declines, with thesole exception of an increase in the use of hands-on techniques in grades K -3.53

Other proposed teaching practices that mightimprove mati.ematics and science instruction in-clude the use of open-ended class discussions,small group learning, and the introduction oftopics concerning the social uses and implicationsof saeoce and technology (often called science,technology, and society, or STS). In particular,

Thinking About Learning Science

We should spend less time ranking children and more time helping themidentify their natural competencies and gifts and cultivate them. There are

hundreds of ways to succeed, and many, many different abilitiesthat will help you get there.

After chapters on students, schools, andteachers, it might seem odd to ask in a separatechapter: How do students learn science and math-__natics? No answer will be found in the follow-ing pages. Indeed, this question now occupiesseveral cadres of scholars and educatorsneuro-scientists, learning theorists, school psychologists,and an abundance of classroom teachers. Educa-tional policy analysts have the luxury of politelyraising the question, acknowledging its complex-ity, and substituting a slightly more tractable setof questions: How can more students be success-ful in science and mi. ' ematics? Does science andmathematics education search for and select a par-ticular type of student? is a certain learning stylefavored in the teaching and learning of these sub-jects? If so, is a self-fulalling prophecy at work?If a certain kind of learning style is appropriateto science or mathematics, can it be promotedthrough programs for "gifted" or "talented" stu-dents? What can be done to correct misconcep-tions (held both by students and teachers), to spurcreativity, to develop "higher order thinkingskills," and to place more students on pathwaysto learning science and mathematics?'

linked to their assimilation of knowledge aboutparticular subjects, it makes little sense to divorcethe two in teaching science. Methods of inquiryand analysis, acquired via laboratory and hands-on experiences, have to be taught together withfacts about particular problems or fields. All thistakes time, and it may be that the amount of ma-terial covered in the typical science curriculumshould be reduced, reserving instruction time forthe use of hands-on techniques.°

The need to increase emphasis on problem solv-ing and thinking skills is often referred to as im-

proving students' higher order thinking skills or"creative thinking." Higher order thinking is theabfity to infer and reason in an abstract way,rather than merely memorizing and recalling sin-gle items of information. These skills have alwaysbeen important, but many analysts believe thatthey will be part of the "new basics" for tomor-row's high-technology work force.'

The concept of higher order thinking may bea metaphor for drastic reform of schools; id andor not, many States are investing money in it.'A particular focus of this trend is testing, whichis widely believed to be one of the main forcesthat perpetuates lower order thinking skills in thepresent day curriculum. In a sense, two relatedtrendsa transition in the generally accepted the-ory of student learning and the pressure for ahigher level curriculumcould lead to positiveimprov cmients in student learning of mathematicsand sciei ce. But change will be slow in coming.'

Learning Styles

There are more similarities in how people learnthan there are differences. However, there ismounting evidence that different modes (such asoral, written, and diagrammatic presentation ofmaterial) are effective with different students.These differences are believed to exist both amongindividuals and groups.8

Individual differences have been clear toteachers for years. Some students concentrate onrote memorization of facts, some explore withtheir hands, others are much more visual and re-spond best to graphical and pictorial presentationof material, while others learn via more abstractimagery. Research is beginning to clarify thesedifferences and to explore their implications forteaching and learning.

Various models of learning styles have been de-vised. Each is designed to help teaching becomemore closely attuned to the ways different stu-dents learn, a'though so far these models have hadlimited effect in classroom practice and none is

°For example, some suggest that whites and Blacks, as well asmales and females. often have characteristically different learningstyles. Not surprisingly, the hypothesis that learning styles differby race, ethnicity, and gender is highly controversial (discussedbelow).

generally accepted.' TI is research builds on along tradition of studies by philosophers, psy-chologists, and cognitive scientists that tracesdifferences in learning to cultural and family back-grounds. Some differences, however, are physio-logical in nature, such as whether students workbest at night or in the morning, and their suscep-tibility to extremes of light, sound, and heat. Howthese differences apply to the learning of scienceand mathematics is just beginning to be clarified.But the heavy focus of elementary and second-ary mathematics and science courses on E e learn-ing and regurgitation of discrete, abstract' as hasalready alerted the science education communityto the need for more hands-on programs, in or-der to break down this misleading image of hatscience is like.1°

Since sc ence and engineering have been histori-cally populated by white riales, it has been as-sumed that teaching approaches that are successfulwith this population are appropriate for all stu-dents. It is further alleged that departures fromthese approaches are not rewarded, and thus per-petuate the factors that deter women and mostracial and ethnic minorities from considering sci-ence and engineering careers. Such deterrents arereflected in the prejudice and discrimination oper-ating in these fields. (See box 4-A.)

As a result of this concept of how science shouldbe taught and learned, science education in theUnited States, some assert, is obsessed with thetesting knowledge of facts to the exclusion of four,

Box 4-A.A Black Learning Style?The relation between scientific values and learning styles is reflected in the concern to improve highschool completion rates among "at-risk" students. A recent booklet, written by the New York State Educa-tion Departmiat to help teachers of at-risl, students improve completion rates, included discussion of mi-nority learning styles. A storm of protest among both minority and majority politicians and educators en-sued.' The booklet states:

. . .understanding various learning styles is . . . important. Several researchers have noted that the traditionalclassroom is built, for the most part, around theAnglo-American cultural learning styles which emphasizes themanipulations of objects such as books, listening stations, learning centers, programmed instruction and so forth.Children's racial, ethnic and emotional backgrounds and cultures influence the manner in which they learn con-cepts and process information. For example, qualities noted in African-Americans include:the tendency to view things in their entirety and not in isolated parts:a preference for inferential reasoning lather than deductive or inductive leasonin,the tendency to approximate space, number and time instead of aiming for complete accuracy;an emphasis on novelty, personal freedom, and distinctiveness; anda resistance to becoming "word" citnendent but developing a proficiency in nonverbal as well as verbalcommunication.'

The existence of a Black learning style partly reflects the acceptance of Black cult ire in American soci-ety. At issue is whether differences arise primarily for socioeconomic or for cultural zacsits, and whichsource is dominant. Some argue that the cultural attributes derived from membership of a particular socialclass are more important than cultural difiarences based on race. Others suggest that Blacks have createda unique Black-American culture, rooted in African traditions but adapted by the American experience,that outweighs socioeconomic factors.3

Several educators have argued that the cultural style and world view of Blacks had been "bastard'zed"by the don: itant culture (the "Anglo-European cosmology") and by its educational system. White childrenare never asked to span and understand both Black and white cultures, let alone the subcultures withineach of them, in the way that Black children are. Specifically, some claim that Black English should beaccepted as a distinctive variant of standard English. The difference arises from the strong oral, rather thanwritten, tradition of Black culture. Blacks use a more descriptive, metaphorical, context-dependent lan-guage, with few synonyms, compared with standard English. They favor the second-person ("you") ratherthan the third-person ("he/she"). Theresult is a language that is more conversational, poetic, and symbolicthan that used by whites; the style in which things are said, for example in public speeches, can be as im-portant as its content. Some argue that the idioms and concepts of Black Englishactually inhibit traditionalmathematics and science learning. However, these same observers believe teaching can be modified andthat, ultimately, Black English is as capable of expressing mathematical concepts as is standard English,although it may use different forms.'A related difference occurs between the intellects. al heritages and styles of inquiry of Blacks and white-Europeans. Some Blacks argue that African-American culture is more affective and "cognitively-united'in a faith-reason-emotion interdependence than is the prevailing white-European culture. Researchers onBlack cognitive style speak of a "feeling intelligence" and the "aesthetic mind." They are suggesting thatthis style is built on what people feel and experience, and an -lyzes the world against that background,rather than through the European tradition: of a world of universal facts and knowledge and a divorcebetween analysis within the mind and the feelings of the body.'

Not all Black educators agree on the importance, or even the existence, of a Black learning style inscience and mathematics. They point out that there is a single accepted language of scientific and mathe-matical concepts that students who wish to progress in these fields must understand. Thus, although theremight be different teaching approaches, they must all converge on the universally accepted language andcontent of mathematics and science.

Learning style differences may also apply to Native Americans and other racial and enic groups.One study of the Navajo culture suggests that, in that culture, students ',earn skills by watching a compe-tent adult performing the action and then gradually taking over mote of the action. Finally, the studentgoes off to perform the skill in private, to verify that he or she has mastered the skill. All this is accom-plished with a minimum of oral communication. In schools, however, students are expected to acquireand demonstrate skills almost simultaneously, to test them in public (in front of the teacher and other stu-dents), and to learn and test skills orally. It is argued that this clash of styles of learning can seriously in-hibit learning by Navajo students.'

Science and mathematics education that recognizes diversity will contribute more to the health of sci-ence and engineering than o:te of narrow gauge that alienates bright, creative, risk-taking students. Sciencewould both benefit and change from this recognition, as the skills that the existing system culls out wculdrefine definitions of scientific "productivity" and "creativity."

and possibly other, domains: processes, creativ-ity, attitudes, and applications.' In their mostcolorful summaries, some observers have arguedthat the United States, by accident rather than bydesign, practices "Westist, sexist, and testist" sci-ence education.12 This approach, if accurate, ismore harmful than simply deterring women andminorities from entering science, for it also dis-

SCIENCE-INTENSIVE ENVIRONMENTS

One insfituti, nal response to individual andgroup difference ; in learning has been the crea-tion of educational environments that give stu-dents greater exposure to mathematics and sciencethan they get in regular schools and classes. Someschools specialize in these subjects. Many schoolsalso provide special classes, including those inmathematics and science, for the so-called giftedand talented. Many students also participate inscience outside the classroom, for example, in re-search participation programs in science labora-tories. (See ch. 5.) Special schools and classes areclearly designed to have special effects on chil-

RD

dren, such as nurturing or maintaining their in-terest, or expediting and enriching their progressthrough the regular mathematics and science cur-riculum. This section reviews data on the extentof these special environments and the effects theyhave.

An Overview of State Programsand Schools

A few States have established special regionalor statewide schools for mathematics and science,often in conjunction with private funding from

82

industry. Illinois, Louisiana, Michigan, NorthCarolina, Pennsylvania, Texas, and Virginiadirectly fund statewide schools that provide spe-cialized subject area study. (See table 4-1.) A to-tal of 15 States sponsor, in whole or in part,schools that focus on science and mathematicsand two more are reportedly making plans to fol-low suit.

In addition or as an alternative to specialschools, a number of States sponsor summer en-richment programs in mathematics and science.These activities are less costly than special schoolsand consequently more popular with the States.Twenty States offer summer programs in scienceand mathematics, although some of them haveonly very small enrollments. Florida appropriatedover $1.2 million las' year for such programs.

More than 30 States also have programs de-signed to :mprove the participation of women andminorities in science and mathematics. SeveralNorthwestern States have programs designed forNative Americans." Various States have begunsponsoring special recognition programs for stu-dents in mathematics and science, such as statefairs and knowledge bowls. California's GoldenState Examination, established under the Hughes-Hail Educational Reform movement in 1983, isdesigned to identify and recognize honors-levelachievement by students in specific subject areas,which include mathematics and science, and is themost comprehensive State-sponsored program na-tionally.

Many recognition and award programs are pri-vately supported by professional organizations orbusiness and industry, or jointly supported byseveral sources (including State and Federal Gov-ernment). These types of programs often beginat the local or regional level and zild at the na-tional level; Invention Convention and Math-Counts are examples. The Westinghouse ScienceTalent Search and the West Virginia NationalYouth Science Camp are privately funded nationalre- ,gnition programs.

Science-Intensive Schou Is

Science-intensive schools provide special envi-ronments for the study and practice of science andmathematics. Such schools are thought to attractstudents interested in science and engineering (in-stead of converting students to such careers), butnational data are lacking to support or refute thiscon.cntion. Such schools tend to attract teachersas well, and are reputed to provid_ high-qualityinstruction in mathematics and science. They aregenerally popular with parents, if for no other rea-son than they expand the choices beyond theneighborhood public school.

There are three iypes of science-intensiveschools: well-established city-soonsored mathe-matics and science schools; State-sponsoredschools; and magnet schools in urban areas, cre-ated to promote racial desegregation, which havemathematics or science as their theme. (See box4-B.)

Box 4-B.Science-Intensive Environments: Two Examples

1. The Governor's School of Science and Mathematics, Durham, North CarolinaThis school became the first publicly financed residential high school in the United States Levoted to

science and mathematics when it opened in 1980. Funded directly by the State legislature, together withprivate donations, it has become a unique and exciting model for precollege science and engineering education.A recent survey found that about 80 percent of its graduates went on to science and engineering majorsin college and two-thirds went to college within the State.'

The school is located in a former hospital in Durham, North Carolina, and is part of the educationaland scientific infrastructure that fuels the continuing economic development of the Research Triangle region.The Governors' School, however, differs considerably from a regular school. It is not run by a school board,but is under the governance of the University of North Carolinasystem, and its teach .., are exempted fromcertification requirements, an innovation that has attracted many who would otherwise teach only at thecollege level (half of the teachers have doctorates). The school enrolls 475 juniors and seniors drawn fromall over the State, though enrollment is scheduled to rise to 600 by 1991, and many of the students areresidential. In the first 4 years of its operation, the school received $19 million from the State and $7 mil-lion from private sources, mainly companies. Education at the school is about four times more expensivethan the average for the State, costing about $1.J,000 per student annually. Admission to the school is onthe basis of test scores, high school grades, student essays, interviews, and home school recommendations.The school's admissions committee pays particular attention to ensuring a gender, racial, ethnic, and geo-graphic balance of its enrollment. In 1984, 47 percent of those enrolled were female and 16 percent wereBlack, Hispanic, or Native American.

The school stresses individual inquiry and group cooperation. Its goal is to 2nrich the traditiJnal highschool curriculum rather than accelerate it. The school particularly encourages students to become involvedin research at nearby Duke University in Durham, the University of North Carolina in Chapel Hill, NorthCarolina State University in Raleigh, and with firms at Research Triangle Park.' More than 4,000 teachersfrom other schools in 'he State have partizipated in teacher training workshops held at the school. Suchcooperation is valuable because the other schools in North Carolina are not nearly so lavish as the Governor'sSchool and have not had much attention devoted to Them.

2. Kansas City, Missouri, Magnet SchoolsThe public schools in Kansas City, Missouri, have recently announced plans to implement, by 1992,

what some have described as "the most comprehensive magnet school court order in history," under whichall secondary and half of all elementary schools would be designated magnet schools.' The Kansas Cityschool system currently enrolls 36,000 students, of which 62 percent are Black and 6 percent are other mi-norities. This program of extensive magnet schools has followed long and messy court litigations that havereached the Supreme Court twice, involving the surrounding suburban school systems, the State of Mis-souri, and a multitude of parents along the way. The program's costs are estimated at $196 million over6 years, part of which will be borne by Federal funds, and part by increased Stat( and local taxation.'

The basis of the magnet program now being implemented is that students can tollow the same themefrom grade 1 to grade 12, with more choice of themes being offered at the higher grades. The themes rangefrom the conventional ones of science and mathematics, computers, and visual and performing arts, toenvironmental .,cience, engineering technology, health professions, law and public service, the military,Latin grammar, and classical Greek.

The Kansas City magnet school program is the most ambitious, and potentially most exciting, in thecountry. Those who will implement it face many problems, including those of funding, renovating build-ings, overcoming considerable local and political suspicion, and finding enough teachers. For example, at-tempts have already been made to bring in teachers with the requisite skills from Belgium.

Some large city school systems have had inten-sive science and mathematics schools for manyyears; examples are New York City, Chicago, andMilwaukee. One of the best known is the BronxHigh School of Science in New York City. Theseschools were founded in the early years of thiscentury, when publicly funded high schools werea novelty, and were strongly prevocational in na-ture. These schools have strong national reputa-tions for the quality of their programs and the dis-tinguished scientists and engineers among theiralumni. Each is publicly supported alongside regu-lar schools in the same district.'

These schools offer a broader range of coursesin mathematics and science than regular schoolsand normally are far better equipped. Laboratorywork is a regular feature of courses, and, often,the schools have good linkages to local firms andresearch laboratories. These linkages help provideequipment, mentors, and, for some students, op-portunities for participation in research. Teachersat these -chools are often freed by school boardsfrom many of the regular constraints on curricu-lum, and can work together with their colleaguesto devise more coherent sequences of materialthan are customarily used. And, because studentsare generally enthusiastic and talented, teachersare keen to 'each in these schools. In addition toscience and mathematics, students take the othersubjects they would take in a regular school.

A new organization, the National Consortiumof Specialized Schools in Mathematics, Science,and Technology, was established in April 1988to share experiences among and represent science-intensive schools. The initial meeting of the con-sortium included 27 schools, and more havejoined since. The consortium is planning meetings

"Because of the novelty of most of these schools, data on theeventual fates of their graduates are not yet available The cityscience-intensive schools also have surprisingly little systematic in-formation on their graduates. One study, conducted 20 years agoby the Bronx High School of Science, is rumored to have shownthat 98 percent of its students go on to college, with less than halfmajoring in science or engineering. One thing is certain only a tinypercentage of each State's high school students attend such schoolsThis, of course, raises questions of costs and benefits to allstudents,teachers, and "regular" schoolswho are part of a school systemthat includes a special school

Magnet schools differ from the other two typesof science-intensive schools in that their primarygoal is to promote racial desegregation rather thanscience education. Such schools, which normallyhave a predominantly minority enrollment, of-fer enhanced programs of instruction in particu-lar areas or "themes" designed to draw studentsfrom a range of racial and ethnic backgrounds.Popular themes include emphases on particularsubject areas, such as science and mathematics;on teaching methods, such as Montessori pro-grams; or on educational c utcomes, such as con-centration on "the basics" or preparation for col-lege attendance. Magnet school programs havebecome a popular alternative to forced busing,and have grown in number from none 20 yearsago to over 1,000 today.'

Magnet School Issues

Since the original objective of promoting racialdesegregation has largely been achieved, magnetschools are now rapidly evolving with the trendtoward increased choice in public education. Theconcept of "schools of choice" is now an impor-tant force in education. School districts that em-ploy magnets are realizing that all their schoolsnever were the same; each has its own culture andinterests. Rather than maintaining uniformity, theconcern is to develop schools of different special-ties and emphases and to capitalize on the spe-cial advantages of each school and community."

The consortium is currently headquartered at the Illinois Math-ematics and Science Academy, Aurora, II.

"There are no current data on the number of magnet schools na-tionally A 1983 survey put the number at about 1,100, of whichabout 25 percent had a mathematics or science theme The magnetprograms are located in more than 130 of the largest urban schooldistricts See R^If K Blank et al , Survey of Magnet Schools Analymg a Model ior Quality Integrated Education, contractor report tothe U S Department of EdLcation (Washington, DC James HLowry & Associates, September 1983) For a survey of magnetschools see Editorial Research Reports, Magnet Schools, vol I, No18 , M,.y 15, 1987

Magnet scnools raise many issues. Among themare whether the introduction of such schools cre-ates a two-class school systemmagnet and non-magnet. Magnet schools are also, on average,more expensive to run than nonmagnet schools.Another issue is the potential drain of talented stu-dents and teachers from the rest of the school sys-tem. Since local politics and school organizationsvary so considerably nationwide, 'here are nosimple rules for resolving these issues.

The school district's choice of admissions sys-tem to magnet programs is especially important.In Philadelphia, for example, the reliance placedon admissions tests by the mdgnet schools hasbeen controversial because of its adverse effectson Black and Hispanic students. Alternatives toachievement test scores as the method of admis-sion include home school recommendations, lot-teries, and queues. The latter two methods are be-coming increasingly popular.

Almost universally, students and parents citethe choices that they are given in magnet systemsas inspiring them to have higher expedations ofpublic education than they had before. Higher Ex-pectations should lead to better performance.There is some evidence, however, that while mag-net programs improve the quality of educationin schools or school districts with a high minor-ity enrollment, minority students are sometimesless likely than white students to be admitted tomagnet programs. This is because magnet pro-grams are generally designed to draw white stu-dents into predominantly minority schools, thegoal being an enrollment that better reflects theracial and ethnic composition of the school dis-trict. In some cases, limits have been put on mi-nority enrollment so that the composition targetsror the school can be met. Such limits can reduce,in the end, the access of minority students to mag-net programs.1°

From a public policy perspective, magnetschools are .omising but unproven. They are de-

signed to promote the goals of equity and excel-lence simultaneously, at somewhat increased cost.Anxieties about the cultivation of elites seemlargely to have been diffused in most workingmagnet systems. Superintendents, administrators,principals, and teachers report enjoying workingin magnet schools, and the magnet schools are ef-fective mechanisms for minority advancement.The key is that magnet schools move the burdenof rules, monitoring, certification, and controlfrom administrators, school boards, and Statesto teachers and principals." This enthusiasm,however, must be tempered by another realiza-tion: in many school districts, students do noteven have the opportunity to learn science inelementary school. In addition, most schools facea serious shortage of equipment for teaching sci-ence, as well as cutbacks in resources availablefor offering "wet" laboratories in high schools. Inshort, the existence of magnet schools is no pan-acea to the problem of making a sequence of sci-ence and mathematics instruction accessible tomore students.

Programs for Gifted andTalented Students

An increasing number of States and school dis-tricts are making special provisions for studentsthey consider to be especially "gifted and tal-ented." Twenty-three States now mandate suchpr, visions, and more are considering such a pol-icy. State spending on such provisions is rising.'

"Linda M McNeil, -Exit Voice and Community MagnetTeachers' Responses to Standardization,- Educational Policy, vol1, No 1, 1987, pp 93-113

`The Council o. State Directors of Programs for the Gifted,The 1987 State of the States' Gifted and Talented Education Re-

port," mimeo, 1987, lists State programs in some detail. In add'tion, the Council for Exception:.] Children estimates that 15 f.ia,eshave special certification requirements for teachers of the gifted +ridtalented. State and local expenditures have increased and are nowabout $384 million (about $150 per gifted and talented child) SeeCouncil for Exceptional Children and the Association for the Gifted,testimony before the House Subcommittee on Elementar Second-ary, and Vocational Education of the Committee on Ec' ion andLabor, on H R 3263, The Gifted and Talented Child e.i and Youthrtct of 1985, May 6, 1986 Industry is also becoming more active,for example, through mentor programs Gifted and talented pro-grams are quite common in other countries where nurturing the bestminds and talents is defined as a necessity See Bruce M. Mitchell


These programs cover all subjects, including per-forming arts, langu- ges, mathematics, and sci-ence. Nevertheless, the provision of programs forthese students remains controversial for two rea-sons: the difficulty of defining criteria for iden-tifying giftedness and talentedness, and the equityand social implications of giving these studentsspecial treatment.

While it is tc be anticipated that the ranks ofthe gifted and talented are especially pnicluctiveof future scientists and engineers, there arP no dataon the number of such students that eventuallymajor in science and engineering. The Council ofExceptional Children, an advocate for gifted andtalented education (as well as special educationof the learning di ibled and handicapped), esti-mates that there are about 2.5 million gifted andtalented students nationally, or about 5 percentof all students. Other estimates put the numberat 5 million."

There is little consensus nationally on the char-acteristics of the gifted and talented. Standard-ized multiple-choice intelligence and achievementtests are widely used to sort students; those whoscore above threshold values on these tests are ad-mitted to gifted and talented programs. Becauseof heavy reliance on such tests, there is some sug-gestion that labeling is prone to cultural, class,and racial bias. The process of labeling as giftedand talented does not appear to be color-blind;it has been estimated that only 13 percent of thegifted and talented are Black and Hispanic stu-dents, whereas about 25 percent of all school stu-dents are Black and Hispanic. As a result of thesepossible biases and of differing cutoffs and defi-nitions of gifted and talented, the proportion ofeach State's school-age population labeled asgifted and talented varies considerably. One studytook 18 commonly used criteria for giftedness andfound that, when applied to fifth-grade suburban(continued from previous page)

Minneapolis classes, 92 percent of the studentscould be labeled gifted in some way."

The basic issue in identifying the gifted andtalented is whether individuals so labeled shouldmerely have demonstrated good progress and highachievement in schoolwork or whether theyshould have some truly extraordinary skills thatmay be undeveloped or unexpressed. Critics ofgifted and talented programs suggest that mostprograms merely identify those who have donewell in the existing system of education. In otherwords, the existing intelligence and achievementtests measure only a limited range of the "gifts"and "talents."

Both proponents and opponents of special pro-visions for the gifted and talented agree that otherdimensions besides "intelligence" and "achieve-ment" should be explored and used. Such dimen-sions might also include intellectu "l, creative,artistic, leadership, and physical and athletic abil-ities. Techniques for labeling need to address eachof these domains separately." Some States, suchas Illinois and Mississippi, are making specialtempts to bring students with different strengthsinto gifted and talented programs.

Even if there were agreemP.- on what. gifted andtalented means, the provision of special programsis politically and socially contentious. Proponentsof special provisions for the gifted and talentedrely on a conviction that such students possessextraordinary talents not posses3ed by the entirepopulation, and that these talents should be de-veloped to the fullest possible extent. Opponentsconsider the creation of such programs to be elitistin nature, in r.acti-x serving the middle acid up-per class students almost exclusively.

Federal support for gifted and talented educa-tion programs is provided under Chapter 2 of theEducation Consolidation and Improvement Act.One estimate suggests, however, that only about20 percent of school districts use any of their

Chapter 2 funds for gifted and talented educa-tion." Several bills introduced in the 100th Con-gress were designed to fund model programs foreducating the gifted and talented, training theteachers of such students, and expanding researchon gifted education.

The Department of Education's Office of theGifted and Talented was disbanded in 1981. Thereare '.ails fcr its reinstatement to ". . . carefully co-ordinate the use of limited federal resources andto provide a much needed focal point of nationalleadership."26 The r_cent reauthorization of Fed-eral education programs includes a provision re-quiring the Department of Education to set up aNational Center for Research and Developmentin the Education of Gifted and Talented Childrenand Youth." Center proponents argue that Fed-eral support has a catalytic role vis-a-vis Statesand school districts, and that the current reformmovement has neglected the gifted and talentedin favor of the mainstream and learning disabled.

The Council for Exceptional Children estimatesthat only one-half of gifted and talented studentsreceive any kind of special assistance. and thatsuch assistance itself is limited so that most giftedand talented students still spend substantial por-tions of time mainstreamed in ordinary classes.The Council estimates that about $400 million na-tionally is spent each year on such special assis-tance, but only about $10 million of Chapter 2funds are spent on such programs.

also comes from Title II of the Education for Eco-nomic Security Act. Some of this funding has beenspent on science-intensive schools, such as theNorth Carolina School of Science and Mathe-matics, which is sometimes included under therubric of "gifted" education. Proponents arguethat this funding, even though it is increasing, isstill too little. There is, however, increasing in-terest within the private sector in such programs.In addition, several university-based programs,such as those at Johns Hopkins, Ohio State, andDuke, identify talented individuals, includingthose in mathematics and science, and provide en-richment programs for them during the summer.

Given that gifted and talented children havebeen identified and that special provision will bemade for them, the basic educational issue is this:whether gifted and talented programs should fo-cus on enriching students' exposure to the exist-ing curriculum or encouraging them to acceler-ate their progress through that program so thatthey complete the traditional sequences of highschool courses a year or two early. A related de-bate concerns whether students should receive en-richment or accelerated classes in all subject areasor only in single subjects, such as mathematics.A final issue is whether such focused instructionshould be provided in dedicated "special" schools,1r as an adjunct to the regular school curriculum.

For able students stifled in the conventional,slow-moving educational system, gifted and tal-ented classes can provide relief and progress suitedto their intellectual and emotional needs. Suchclasses can also help keep such students in school;many of those who drop out of school are bored,but gifted, children. The basic argument for spe-cial treatment of the gifted and talented is thatwithout it these students would be ignored or un-challenged by the existing school system.

CLOSING THOUGHTS: A LARGER MENU?

The debate over gifted and talented studentsbegs very different questions about educationalmethods than the debate over alternative learn-ing styles. The problem addressed by educatorsconcerning different learning modes is the nega-tive reinforcement and frustration many other-

95

wise talented people experience in the traditionalclassroom. In mathematics and science learning,this has tended especially to be the case withwomen, and racial and ethnic minorities. Theteacher of gifted and talented students faces adifferent problem. These students have already

demonstrated some proficiency or success in thepresent system; the educator's task is to sustainstudent it terest and progress.

Both issues have similar implications for sciencez..nd mathematics education: How can more stu-dents be siccessful in science a... mathematics?What doe:; it mean to be talented in science ormathematics? How should such talent first beidentified, and then nurtured? Are special schoolsor prograris needed? Will innovative curriculathat reflect new insights into how students learnand how different their learning styles maybespark the interest and fulfill the potential that

teachers and parents often recognize in thei c'lil-dren? Will new thinking about learning penetratethe schools? Will it be effective in "calling" morestudents to science and mathematics, helping themfulfill expectations (rather than ill-foundedprophecies), while propelling them to the nexteducational stage and, ultimately, a career in sci-ence and engineering?

These questions reflect high expectations for sci-ence and mathematics education. Indeed, thischapter has glimpsed a larger menu of issues,needs, and signs of progress.

Learning Outside of School

The children who see colored shadows on the wall in the Exploratorium havenot "learned" something you can test. But years later, when a teacher triesto explain light patterns and perception, this experience will be u part of the

deep background that will make learning easier.

National concern about the excellence of Amer-ican schools has sometimes detracted from the rec-ognition that children learn a great deal out ofschool. The influences of family, friends, the me-dia, and other features of the environment out-side of school are profound.

The out-of-school environment offers oppor-tunities to raise students' interes in and aware-ness of science and mathematics. Table 5-1presents estimates of the proportion of the school-age population that participate in science-relatedinformal education activities. Such informal activ-ities draw strength from the local communitychurches, businesses, voluntary organizations,and their leaders. All are potential agents ofchange. All are potential filters of the images ofscience and scientists transmitted by television andother media. These images are often negativenearly always intimidatingand shape youngpeople's views of science as a career.

Science centers and museums, for example, canawaken or reinforce interest, without raising thespectre of failure for those who lack confidencein their abilities. (As Frank Oppenheimer, founderof San Francisco's famed Exploratorium, noted,"Nobody flunks a museum.") Intervention pro-

Family circumstances are pivotal influences oncareer choice. Parents' occupations, attitudes, in-comes, residences, and socioeconomic class areall reflected in their children's lives.

Although it can be illustrated in many ways,the strong influence of families is indicated by bio-graphic data on winners of the Westinghouse Sci-ence Talent Search (WSTS). The WSTS is one ofAmerica's oldest high school competitions in thesciences. Between 1942 and 1985, it awarded $2million to 1,760 young scientists. Its winners havegone on to earn five Nobel Prizes, two Fields Me-dals, and four MacArthur Foundation ("genius")Awards.

For example, in the 1985 survey, 35 per-cent of winners had fathers who were professionalscientists or engineers.

THE PUBLIC IMAGE OF SCIENCE

The public image of science and engineeringconveyed by television and the other media is am-biguous. On the one hand, science is portrayedas being of great benefit to economic progress andto health. On the other, it is portrayed as a sinis-ter force that bestows power on its adherents andis manipulated by inhumane people.' In anycase, the process of scientific and technologicaladvance is poorly understood by the public. Whilethe sometimes dismal image of science is one partof the cacophony of discouraging signals that anaspiring young scientist receives (and will certainlycause some students to shun science), evidencesuggests that poor images of science are probablynot a leading cause of students' failing to pursuecareers in these fields. Academic preparation ulti-mately is far more important.'

Television Images of Science

The public image of science has been studiedin a number of separate settings over the years.One study dissected the content of network prime-time dramatic programs between 1973 and1983.6 The study found that: 1) some aspect ofscience and technology appears in 7 of every 10dramatic television programs; 2) doctors are morepositively portrayed than are scientists; and 3) sci-entists are not as successful in their on-screen oc-cupations as other occupational groups. In fact,for every scientist in a major role who fails, twosucceed, whereas for every doctor who fails, five

The study also documented a linkbetween these images and viewers' attitudes andconcluded that, while television dramas generallypresented positive images of science, the more thatviewers see, the more they perceive scientists asodd and peculiar.

Television is a pervasive influence on many stu-dents' lives.' It is argued that the effects of tele-vision viewing may be strongest for children un-der 11 years old, because up until that age childrenare continuing to develop interpretive skills andsophistication in analyzing the content of mate-rial. ' Children's attitudes toward televised ma-terial will be influenced, in other words, by whatthey have seen and learned of the world. As chil-dren grow older, television is critical in the for-mation of an understanding of social relationshipsand of the social forces that govern adult life. Thiswindow on the adult world may be particularlyimportant in shaping attitudes toward careers andoccupations, because adolescents have few socialcontacts outside their own age group.°

Television viewing can have positive and neg-ative effects. It can promote racial and sexualstereotypes and perceptions of occupational segre-gation, or help change attitudes toward the races

However, tele-vision viewing by adolescents is reported to haveremained roughly constant over the time that, forexample, Scholastic Aptitude Test scores havefallen."

From a policy perspective, however, even if alink between television portrayals of science andengineering and career aspirations were estab-lished, the challenge would be to design televisionprogramming that could affect those aspirationspositively. Research suggests that it is easier tochange attitudes, and therefore aspirations, thanto change behaviors:2

Students' Images of Science

In a nationwide study sponsored by the Amer-ican Association for the Advancement rf Science.(AAAS) in 1957, high school students were askedto compose short essays describing their impres-sions of scientists and their work. Margaret Meadand Rhoda Metraux wrote a composite descrip-tion of science and of scientists from their read-ing of 35,000 such essays.'3 They found that:

The Potential ofEducational Television

Educational television can be a powerful wayto introduce new images and teach students. Aprominent example is the Children's TelevisionWorkshop's 3-2-1 Contact, funded by the Na-tional Science Foundation (NSF) and the Depart-ment of Education, and broadcast daily on mostpublic television stations. This show's target au-dience is children 8 to 12 years old (although manyyounger children watch as well). Its aim is to in-terest these students in science, with particular em-phasis on female and minority children. Exten-sive research has been done on this series. It isestimated that the series is seen in ne'rly one-:ivarter of all households with at least one childunder 11 years old. Themes in 3-2-1 Contact areechoed in series-reldA science clubs and a maga-

The impact of a television message may dependmore on the characteristics of the viewer, suchas his or her age, than on the characteristics ofthe message. OTA finds no compelling supportfor the hypothesis that poor images of science bythemselves deter students from science and engi-neering careers. Television is a powerful force,both for good and for bad, but its effect also de-pends on the prior experience and knowledge ofviewers.

The Informal Environments Offered byScience Centers and Science Museums

Science centers and museums aim to bring sci-ence alive with exhibits and displays that showscientific phenomena in action, and dedicatedstaffs determined to spark interest in science. Theyhave important positive effects on students' atti-tudes toward science and knowledge of physicalphenomena.

Science museums were first set up to house andarchive the achievements of science and technol-ogy through artifacts such as experimental appa-ratus, machines, field notes, and pictures. As atti-tudes toward science and science learning havechanged, new institutions, called science centers,have sprung up with the primary aim of excitingand educating v'sitors in science and technologyrather than of chronicling its history.' Indeed,iiiis development was presaged by science mu-seums. At the turn of the century, the DeutschesMuseum in Munich, West Germany, was the firstscience museum to invite the public to participatein its exhibits, and to introduce cutaways andworking models to encourage the public to learnabout how things work rather than what theylook like. This model was soon copied for use inthe new Chicago Museum of Science and Indus-try in the 1930s. The preeminent example of a sci-ence center is the Exploratorium, in San Francisco,which opened in 1972.

Today, both science museums and sciencecenters use "hands-on" exhibits to illustrate sci-entific principles through "object-based learning"that schools and school systems often cannot pro-vide because the equipment is too expensive orunavailable.' Science centers are also makingincreasing use of new technology such as com-puters, video and videodiscs, both as exhibits intheir own rignt, and as a means of illustrating sci-entific and technological concepts.

Learning in Science Centers

The learning that occurs in a science center isgrounded in the relevance of science to practicaldaily life, in arousing curiosity, and in allowingpeople to explore and explain for themselves.Most important, it has no particular aim; no testsare in sight, no goals are prescribed or proscribed,and visitors are free to choose the exhibits thatthey would like to explore in detail and to ignorethe rest. The function of these centers, f.om thepoint of view of the education of future scientistsand engineers, is not so much to teach scientificconcepts, as to interest students and to relate ab-stract learning in schools to experience of howphysical phenomena work and can be altered byhumans.

Nationally, there are about 150 centers andmuseums dedicated to improving public under-standing of science and technology; an umbrellaorganization, the Association of Science-Technol-ogy Centers (ASTC), represents most of thesecenters. A recent survey by ASTC indicated thatthese 150 centers had about 45 million visitors in1986, up from 32.5 million in 1979.18 Part of thisincrease is due to expansion in the number of sci-ence centers; over one-half opened after 19f 0, and16 percent opened after 1980. The survey suggeststhat as many children and young people as adultsvisit the centers. Probably about 6 million chil-dren and young people come on school trips. In-terest in science centers is very high. Once largelythe preserve of large cities, centers are now be-ing built in many smaller towns, cities, and ruralareas.

The people who work in science centers areskilled at helping both adults and children learnabout science. Science centers' target audience isthe population that is curious but not confidentabout science. About 100 science centers conductmathematics and science teacher training pro-grams, funded by school districts, States, or Ti-tle II funds from the Federal Government. Theseprograms often aim at elementary and middleschool teachers, many of whom have almost nogrounding in science. About 65,000 teachers par-

ticipated in such programs in 1985. Few centershave programs for high school teachers.'

Science centers have developed close workingrelations with school systems in the areas in whichthey serve, while remaining independent of them.This unique role is often cited as b-;ng useful, be-cause it allows the centers to talc, risks and ex-periment in science education in ways that schoolsystems find difficult. Nancy Kreinberg, Direc-tor of the EQUALS program (see box 5-A) basedat the Lawrence Hall of Science in Berkeley, Cali-fornia, has pu: it this way:

We are in the schools, but we are not of theschools. We are in the community, but we don'trepresent one faction of the community. We areseen as representing a lot of different interests, andI think that is an enormous source of strength thatevery science center has to offer."

Box 5-A.The EQUALS Program

EQUALS is a program designed to improve theawareness of gender- and race-related issues inmathematics and science education. It encom-passes projects for teachers, counselors, adminis-trators, parents, and school board members topromote the participation of female and minoritystudents in mathematics and computer courses.EQUALS provides curriculum materials, staff de-velopment seminars, and family learning oppor-tunities. It is located at the Lawrence Hall of Sci-ence (University of California at Berkeley). Since1977,14,000 California educators and 9,000 edu-cators from 36 other States and abroad have par-ticipated in EQUALS courses. Sites have beenestablished across the United States.

Evaluation data from extensive interviews andquestionnaires indicate that EQUALS programsincrease student enrollment in advanced scienceand mathematics classes, improve attitudes andinterest in related occupations, enhance theprofessional growth of teachers, and, perhapsmost importantly, encourage parent involvementin the schools (the Family Math Program is cur-rently being evaluated with National ScienceFoundation funds). EQUALS publications, in-cluding We All Count in Family Math and I'mMadly in Love With Electricity and Other Com-ments About Their Work by Women in Scienceand Engineering, are geared for use in all typesof "classrooms," since the emphasis is on hands-on, active problem solving. Materials in Span-ish are also available and widely used.SOURCE EQUALS Program, Lawrence Hall of Science, Uruversity of Califor-

into heterogeneous groups of 5 to 10 studentsdrawn from different schools, neighborhoods,races, and ethnicities), the program makes use ofexisting facilities that are neither available toschools nor would readily fit into existing schoollearning patterns and curricula.'

Costs and Benefits

A recent survey indicates that the average sci-ence center costs about $1.5 million per year torun, and that most charge between 75 cents and

'Judy Diamond, Natural History Museum, San Diego, personalcommunn otion, lune 1088

1n

$5 for admission.22 About 40 percent of expensesincurred by the average center are defrayed byadmissions, memberships and other fees, andfrom sales of souvenirs and food; State and localdistricts pay, on average, about 28 percent of thecosts, while corporations contribute another 10percent. The average contribution of the FederalGovernment to ASTC member centers is 6 per-cent, but the bulk of this goes to the three centersit wholly supports.' The remaining centers re-ceive, on average, just 2 percent of their incomefrom Federal sources.

Several Federal programs fund science centers,including the Informal Science Education Programof NSF, the National Endowment for the Human-ities, the National Endowment for the Arts, theInstitute of Museum Services, and the DEpartmentof Education's Secretary's Discretionary Fund.Only the Institute of Museum Services will con-tribute toward routine operating expenses (andit sets a limit on its contribution of $75,000 permuseum per year); the other sources will fundonly particular programs and novel educationalprojects. Indirect Federal support has in the pastalso come from contributions of equipment andfacilities. (Seattle's successful Pacific Science Cen-ter, for example, is housed in the United Statespavilion built for the 1962 World's Fair, whichwas given free to the center.)

Evaluations of the effects of science centers onstudents are limited. The research that has beendone indicates that science centers can be effec-tive arenas to demonstrate aspects of the naturalworld, but have more limited impacts in convey-ing understanding of the scientific concepts under-lying particular exhibits. Visitors often acquirelasting memories of phenomena, such as the for-mation of a rainbow by the use of a prism, butare less readily able to exrlain what they have seenor give the proper scientific terms that describethe phenomena. Written information beside ex-h;bits is not often well assimilated. Visitors thus

build up a good intuition of how things work,based on their experience of phenomena, but lit-tle analytical knowledge. Students who are usedto figuring things out for themselves, ignoring in-structions, often find science centers interesting;the style of learning that science centers employis radically different from that in formal class-rooms where the emphasis is often on obeyingrules and memorizing facts.

Learning that takes place in science centers isthus difficult to measure using conventional testsof factual recall (which do not demonstrate "learn-ing" at all), but is clearly important. When fam-ilies visit and explore exhibits together, parentscan often become more confident about scienceand hence more supportive of any interest thattheir children might develop." An interestingstudy of the "Explainer" program at the Explorato-rium, in which nonscientifically inclined but en-thusiastic high school students explain particularexhibits to visitors, found that, 10 years later,former Explainers were still very interested andconfident in science, academic pursuits, and workexperiences. (See box 5-B.)

ASTC is working to improve attendance ai:duse of science centers by females and minorities,and is encouraging its members to form links with

'Diamond, op cit , footnote 21

community and service organizations in the fe-male and minority communities, such as the Na-tional Urban League, Girls Clubs of America, andthe National Action Council for Minorities inEngineering." Several foundations are helpingfund such outreach programs. Minority students,in particular, often need to be encouraged to de-velop interests in science and engineering, and sci-ence centers can help build their confidence inthese areas. Several science centers have heldhighly successful "camp-ins," in which studentsor teachers spend a whol_ night learning and play-ing in a science center.

Informal Learning

Informal education, then, is not just museumsand science centers. Informal learning also takesplace through reading, watching television, visit-ing libraries, and participating in clubs. It is thisadditional informal education, as one NSF stafferplus it-4-H Clubs, Girl's Club of America, GirlScoutsthat warrants ". . . a concerted effort togive kids direct hands-on experience."26

INTERVENTION AND ENRICHMENT PROGRAMS

Some kinds of informal education programs aredesigned to enrich, or even replace, traditionalschooling in mathematics arid science. One formis the "intervention program," designed to im-prove educational opportunities for special groupsnot often well served in regular classrooms (par-ticularly females and minorities). Other programsfor the entire school population allow students toparticipate, for example, in science experimentsin research laboratories, including Federal labora-tories, or to enhance their progress through theregular school mathematics and science curricu-lum. These programs are known as enrichmentprogams.

Intervention Programs

Ideally, all students would have access in schoolto high-quality courses in mathematics and sci-ence, and their teachers, fellow students, and guid-ance counselors would be sensitive to the overtand cove. t racism and sexism that interferes withlearning. In practice, however, the quality ofcourses is very uneven, and social attitudes stilldeter females and minorities from pursuing fur-ther science and engineering study. While schoolsare reforming and improving the situation, changeis slow and certainly lagging the demographicchanges already occurring. Negative attitudes

Box 5-ILLearning by Teaching: The Explainer Program at San Francisco's Exploratorium

One of the most powerful ways to lea-n is by teaching others. The Explainer program at San Fran-cisco's Exploratorium, a science center designed to offer visitors -. iximum involvement with scientificphenomena and experiments, gives a small s3:oup of enthusiastic teenagers just this chance. Explainer3 arelocated around some of the Exploratcrium's exhibits to help visitors by conducting demonstrations an-swering questions, an(' sparking discussion about the concepts that the exhibits convey. The Explainer pro-gram is intended both as a service to visitors to the Exploratorium, and as a work and educational programto give teenagers an appreciation for science and for learning.

The Exploratorium recruits Explainers from local high schools for their enthusiasm for working withthe public, rather than for their interest in science as such. The program deliberately reaches out to stu-dents outside the academic and science mainstream, good grades or interest in science are not prerequisites,and in fact are not exsired. Potential Explainers have tc be friendly and keen to help visitors, and representdiversity among tie population. Over one-half of Explainers are from minority groups; they are equallydivided between males and females.

Explainers are hired for a 4-month session, are paid an hourly wage, and receive about 50 hours ofpaid training before and during the job. The program costs the Exploratorium about $250,000 per year(or about $4,000 to $5,000 per Explainer). Most Explainers work only one session.

An evaluation of nearly 00C alumni of the Explainer program was conducted in 1985-86.' Former Ex-plainers universally report that their stint at the Exploratorium was a treme-dous learning and social ex-perience, as well as a boost to their self-esteem. One of the greatest benefits the Explainers cited was work-ing intensely with a small, diverse group (15 to 20 Explainers work with visitors at any one session), andenjoying professional cameraderie with the Exploratorium staff. Explainers acquired confidence in theirability to learn about subjects they had previously thought inaccessible. They learned to deal with not know-ing "all the answers"; they also developed communication and people skills that they later found valuableat college and in the workplace.

Among the comments made by former Explainers were these:There ould be times when something didn't catch my interest in class, but it did when I learned it

here. :t wa., hands on. There was actual proof. It wasn't something read from a textbook.I learned to tolerate a lot of my own mistakes. . . . You learn to appreciate that you can learn from

those that know better Once at an eye dissection, I got into a conversation with an ophthamology student.I'd be explaining things but all of a sudden I was learning new stuff by talking to this guy.

It got rid of a stigma for me and let me go and pursue science, which is really what I wanted to doin the first place. I found out that, yeah, you can enjoy science and you're not weird if you do, so whynot ( Before, I woulc' lust keep it to myself. I never told anybody that I read science books before I came here.

That was one of the key things to come out of the Exploratorium experience: becoming a people-orientedperson. When you explain something and you see the spark in people's eyes, you are enriching them. Youare giving them something, and in return you're getting the feeling that you are enriching their lives.

Part of the reason I liked it a lot was that it gave me the feeling that I was teaching for the first time.I was showing people things instead of always having them shown to me.

In sum, the curiosity and desire to learn that Explainers acquired stayed with them in their later lives.Women were much more likely than the men to report that they became interested in science and engi-

neering and improved their communication skills as a result of the Explainer program. Students who werealready interested in science and engineering strengthened their confidence; other students gained generalself-esteem and were encouraged to go to college.

The Explainer program also helps visitors enjoy themselves and learn. Explainers can particularly helpreach their peersother teenagers who traditionally have been tough customers for science centers and

museums to reach. Compared to other age groups, it is believed that comparatively few teenagers attendmuseums; one study found that many teenagers felt that most museum staff were "patronizing and condes-cending."

Some other science centers have adopt!d the Exploratorium model directly and many others have de-veloped other outreach programs for teenagers, including summer classes, meatorships, interpretive guides,and museum staff internships.' Many target high-ability, science-oriented students; others are directed toenthusiastic students who are willing to take the job on a volunteer basis.

toward careers in science and engineering can-veyed by influences outside schools, such as themedia, families, and friends, will not readily bealtered.

Against this background, special efforts to in-tervene must be made in order to attract and en-courage females and minorities in science andengineering. Most of these efforts, though few innumber, take place out of school during students'free time. Although intervention programs haveonly been in existence for about 20 years, manysuccessful techniques have been developed forboosting the self-image, enthusiasm, and academicpreparation of females and minorities for scienceand engineering careers. Indeed, some of thesetechniques (such as stressing the relevance of sci-ence understanding to everyday experiences, theuse of small groups, and pal iicipation in hands-on activities) clearly warrant dissemination to theentire population of students.

The Content and Reach ofIntervention Programs

The Office of Opportunities in Science ofAAAS collects data on intervention programs,and is an enthusiastic advocate of them.' Theprograms differ from each other considerably interms of their longevity, bases of operation,sources of support, goals, and quality. Universi-ties, museums, and research centers house the

majority of intervention programs, and manyserve junior high and high school students. Mosteffective intervention programs involve learningscience by doing, rather than through lectures orreading; working closely with small groups ofother students; contact with attentive advisors,mentors, and role models who foster self-confi-dence and high aspirations; and an emphasis ondisseminating information about science and engi-neering careers. Intervention programs for minor-ity students often reach a high percentage offemales as well, both minority and majority.Evaluations suggest that early, sustained interven-tion can bring minority achievement to the samelevel as that of white males.

AAAS has examined exemplary interventionprograms and has f and that they have strongleadership, highly committed and trainedteachers, parental support, adequate resources,a sustained focus on careers in science and engi-neering, clear goals, and continual evaluation.Many combine academic and informal learning,and involve teachers and parents. They often fo-cus on enriching students' experiences in science,rather than in providing remedial treatment forthe poor quality experiences that most studentshave had from formal education; many also stresstechniques, such as peer learning, that help stu-dents learn how to learn. The intervention pro-grams that work best start early in students'educational careers and have a long-term focus,with the ultimate goal of making successful in-tervention techniques part of the normal appa-ratus of the school system.

Most intervention programs require extraordi-nary staff commitment and support, and are noteasy to replicate in other locations. The mosttalented teachers and leaders can only fully servea limited number of students, even using technol-

Differences Among Intervention Programs

Intervention program,. -ecognize the differentproblems that can face females and minorities inscience and engineering. Most females, for exam-ple, have access to the high school science andmathematics courses that they would need for sci-ence and engineering careers; the issue is one ofself-image and self-confidence. Some female stu-dents mistakenly believe they do not even needto take optional mathematics and science coursesfor entry to science and engineering majors in col-lege. In addition, during group work in class-rooms, male students frequently dominate exper-imental equipment and computers, leaving femalestudents taking notes and acting as "secretaries."In all-female intervention programs, each studentcan fully participate in opera'ing equipment andenjoy the whole experience of makiug scientificobservations. Intervention programs need to fo-cus on encouraging an interest in science and im-proving student self-confidence in mathematicsand science.

Many minorities, on the other hand, do nothave access to the necessary mathematics and sci-ence courses and are less likely than whites to plant" attend college. While many Blacks and His-panics are interested and aware of science andengineering careershistorically a route to socialmobilitythey lack the preparation to enterthem. Accordingly, intervention programs needto improve the probability that minorities will beprepared to attend college at all, and then focuson improving their learning of mathematics andscience.'

Within the minority population, however, thereare significant differences that affect the designof intervention programs. Many Me tic --Americans come from poor rural backgrounds and have

strong family bonds, but tend to receive little en-cow agement at home for 'book learning." Cuban-American students often come from will-educatedfamilies and do very well in acaden,:, ,,ursework.Black students in northern cities may be awareof the rewards of science and engineering, but areoften poor and enrolled in poorly funded schoolsystems; their access to necessary courses islimited. Black students in the South, however, aremore likely to live in rural areas, and have lessknowledge of (and correspondingly, interest in)science and engineering careers. Programs forBlack students are needed early in their educa-tional careers, because deficiencies in preparationaccumulate at an early age. Asian-Americans areoften very well prepared for science and engineer-ing careers, but those from territories of the UnitedStates with significant Asian populations, PacificIslanders such as American Samoa, tend to lackpreparation.

Funding Intervention Programs

Despite the effort that has been put into devel-oping intervention programs in the last two dec-ades, and the urgent need for them, there is stillonly a modest number of programs and, collec-tively, they reach only a small proportion of theirtarget populations. The leaders of several majorintervention programs meet as the National Asso-ciation of Precollege Directors (NAPD), whichestimates that intervention programs reach 40,000minority students annually (or less than 1 percentof the total minority student population). But25,000 participants in NAPD programs have grad-uated from high school, over half to major in sci-ence or engineering." Expansion is limited bothby the shortage of individuals prepared to com-mit the time and energy necessary to initiate theseprograms and by lack of funding. A local baseof support seems to be an essential ingredient ofsuccess.

Some intervention programs owe their originsto Federal funding, Many today are supported byStates, foundations, and industry. Federal funds,

The council's educational programs supplement school offerings, their rationale being that enrichmentprograms improve the educational experience of Hispanic children more than do remedial programs thatrepeat school lessons. The council serves as a national advocacy organization to encourage systemic re-forms in teacher training, continuing education, and effective school practices. Project coordinators areconfident that much change can be initiated through community-generated local projects. The fivecommunity-based approaches are the Academia del Pueblo, Project Success, Project Second Chance, Par-ents as Partners, and the Teacher Support Network.

The problems of early academic failure and the large number of Hispanic children who must repeatgrades are addressed by the Academia del Pueblo, which provides after-school and summer "academies"for elementary school-aged children. These efforts help students meet and exceed grade promotion require-ments. Project Success provides career and academic counseling to help junior high students raise theirexpectations and to support their eventual progress to high school graduation. Project Second Chance tar-gets dropouts using volunteer mentors and tutors. The Parents as Partners program was designed to rein-force the concept that parents are effective teachers, a concept that is particularly influential h Hispaniccommunities. This project trains and assists parents to encourage and be tutors to their children. The TeacherSupport Network brings together community resources to train and support both Hispanic and non-Hispanicteachers who work with Hispanic children.

The council assists demonstration sites with the necessary training and technical assistance to imple-ment the models, and monitors and evaluates the projects. The council also transfers lessons arising fromdemonstration projects. A necessary component of any council program is the development of participants'Spanish language skills, either as an integral component of the curriculum or as a second language. In addi-tion, the council is assisting the Association of Science-Technology Centers to identify Hispanic community-based organizations with a mathematics and science education focus to encourage their participation inscience centers and museums.

however, play an important base role. Since manyintervention programs piggy-back on existing fa-cilities in schools, science centers, research lab-oratories, and universities, the programs arerelatively inexpensive. They are labor- not capital-intensive, and many have budgets of several hun-dred dollars per student. (College-level programstend to be more expensive, sometimes around sev-eral thousand dollars per student, although thissum might include tuition and scholarshipsupport. )

Intervention programs were one outgrowth ofthe civil rights movement of the 1960s. Federallaw eventually was extended to address manyforms of discrimination, by race, sex, handicap,

and age; intervention programs began to attractFederal funding as a way of breaking down someof the barriers to full participation of these groupsin science and engineering. One source of thefunding was the Women's Educational Equity Actof 1974, administered by the Department of Edu-cation. Another was grants for State programs,funded under Title IX of the Higher iticationAmendments of 1974. Federal funds have oftenacted, and been most effective, as seed fundingto initiate intervention programs; if successful,such programs have sometimes then been fundedby States and industry in their community.

By contrast, NSF historically has not empha-sized either intervention programs or other ways

Box 5-D.American Indian Science and Engineering Society

The American Indian Science and Engineering Society (AISES) is a nonpolitical, national orbanizationof American Indian scientists and engineers. The society's primary purpose is to expand American Indianparticipation in science and engineering careers and to promote technical awareness among other Indians.Since it was founded in 1977, AISES has grown to represent 61 tribes in 36 States and Canada. Projectsare designed to encourage academic excellence at all education levels. The precollege programs coordinateteacher training seminars and summer enrichment programs, provide materials (including computers), in-troduce role models through science fairs and camps, sponsor competitions, coordinate student chapters,and publish newsletters and videotapes. Collegiate programs include mentorships, internships, and work-shops. The Collegiate Chapter Program includes an annual 2-day conference for leadership training andfocuses on providing scholarship information and peer support at 35 institutions. Professional programsare also available for Indian scientists and engineers.

Funding sources are public and private, including the National Science Foundation, the Departmentof Education Fund for the Improvement of Post-Secondary Education, the National Aeronautics and SpaceAdministration, Hewlett Packard, and Hughes Aircraft. The society also earns some income from the pub-lication of Winds of Change, a quarterly magazine designed to disseminate information on educationalopportunities and AISES activities, and to promote involvement of Indian and non-Indian participants inIndian concerns. To benefit from AISES programs, schools and agencies must affiliate with the society.The society's annual conference brings together Indian students, the affiliates, and non-Indian professionalsfrom the public and private sectors.SOURCE: American Indian Science and Engine ins Society, Boulder, CO

Box 5- E.-- Philadelphia Regional Introduction for Minorities to Engineering

Founded in 1973, Philadelphia Regional latroductiGn for Minorities to Engineering (PRIME) is a non-profit corporation devoted to creating opportunities for minorities in engineering, pharmacy, and othermathematics- and science-baeld professions. PRIME was incorporated in 1975 as a partnership of Philadel-phia area businaces, government agencies, colleges and universities, professiond associations, and parentgroups, end caters to P.Wm' and senior high school students in the Philadelphia, southern New Jersey, andGreater Delaware region. The program is funded by member organizationsincluding 32 compa-nies, 6 State and local agencies, and every 'major local college and university hi the region. Each of theseorganization's/Active interest in improving the number and quality of young minority engineers has helpedensure the progrant's success. Original support came from the Sloan Foundation, but institutional supporthas been-steady. The program's success is evident in its longevity, continued expansion, and the high per-centage of the program's students who graduate college and enter their chosen professions.

PRIMIrlidentification Of students interested in mathematics and science subjects begins in the seventhgrade. Early won, it Is believed, contributes k, the pr gram's success. "Capable" minority students(as defined by ,test scores, teacher recommendations, and scholastic achievement) are provided with spe-4:biked supplementary activities, counseling, and monitoring throughout the remainder of their academicyears. Hands-on projects are emphisized in classes, and industry and government representatives visit class-rooms monthly, providing role models.

Students also interact with member agencies through workshops and field trips. During the summer,PRIME offerwcompetitive based residential training programs (PRIME Universities Program),sponsored originally by a grant of ,000 from General Electric. While in college and after graduation,students receive job referral and placement assistance. Guidance is continuous; students receive advice oneverything from how to cope with precollege coursework to selecting an appropriate university and ob-taining financial aid. Enrollment in the summer program is 80 percent Black and 5 percent Hispanic; theacademic year program includes only Black students. Both programs have equal numbers of males andfemales.

PRIME serves more than 3,000 students each year. Recent statistics show that 92 percent of PRIMEhigh school graduates enter college, and 73 percent of those enter technical and/or engineering programs.Eighty-five percent earn baccalaureate degrees.SOURCE: PliUME, Inc.. Philadelphia. PA.

of improving the "career chances" of females andminorities in science and engineering. NSF pro-grams that have had some success include: theWomen in Science program (1974-76, 1979-81):the Resource Centers for Scislice and Engineer-ing program, aimed at minorities (1978-81); andthe Research Apprenticeship for i\,:nority HighSchool Students (1980-82). None of these pro-grams was reestablished when NSF's Science andEngineering Education (SEE) Directorate was re-born in 1983, although the Research Apprentice-ship for Minority High School Students and theResource Centers program have recently beenresurrected. With these two exceptions, none ofSEE's current programs directly address "under-represented" groups Programs for these groupshave not been well funded through other NSF ef-forts, although some receive funding (for exam-

ple, through Science and Mathematics EducationNetworks, and Teacher Enhancement). SEE en-courages the submission of proposals for projectsto address underrepresented groups.3°

Funding sources for intervention programs havevaried according to the progi am's target popula-tions. Mission agencies have set different priori-ties. NSF and the Department of Education haveestablished intervention programs for females;foundations, the military, and other Federal agen-cies (such as the Department of Health and Hu-man Services, the National Aeronautics and SpaceAdministration, and the Department of Energy)

have tended to fund programs for minorities.Overall, however, there have been few sustainedfunders of "women in science" programs. Muchtargeted human resource support is done institu-tionally to categories such as historically Blackcolleges and universities. But this support, too,seems modest relative to the number of lives theyare supposed to change and careers they claim tolaunch."

Initially, intervention programs were based out-side schools. Schools, in fact, have often beenviewed by advocates of intervention programs aspart of the problem rather than part of the solu-tifin. But in recent years, schools have increas-ingly begun to work with intervention programssuch as the METRO Achievement Program inChicago. Interventions such as the Ford Founda-tion's Urban Mathematics Collaboratives workdirectly with mathematics teachers outside the

310TA research found that benefactors scale down their gifts tofit their expectations of success when historically Black institutionsare involved. Foundations that give $1 million to an Ivy Leagueschool will give an institution with primarily minority enrollment$100,000 for the same activity. Also see Tom Junod, Are BlackColleges Necessary?" Atlanta, vol. 27, October 1987, pp 78-81.

CONCLUSIONS

It is clear that intervention Lnd enrichment pro-grams are a valuable supplement to formal edu-cation. The expectations and attitudes of parentsand teachers; differential access to courses, in-strumentation, and educational technologies; andlack of information or mentoring by role modelsiead many female and minority students awayfrom science and engineering careers. The mag-nitude and complexity of the problem requires alarge and continuing effort.

Experience with intervention programs has pro-vided considerable knowledge on elements of suc-cessful models to replicate in future programs. Thereasons why intervention programs have failed,not surprisingly, have tended not to be well doc-umented.

school systems in the cities that the programserves; this frees teachers from the organizationaland attitudinal constraints that such systems en-gender. It is important that intervention programscomplement efforts to improve the formal edu-cation system.

Enrichment Programs

Many programs are designed to enrich or speedthe progress of talented individuals through sci-ence and mathematics courses. Several Federallaboratories, most prominently those of the De-partment of Energy, provide summer researchparticipation programs that allow students to ex-perience science in the flesh by active participa-tion in real research. While there is no conclusiveevidence that such programs change students' ca-reer destinations, they have a potent effect in con-firming student inclinations that research can befun. Several universities operate summer coursesin mathematics and science for talented individ-uals. The best known are the Center for the Ad-vancement of Talented Youth at The Johns Hop-kins University and the Talent IdentificationProgram at Duke University. (See box 5-F.)

When provided with early, excellent, and sus-tained instruction and guidance, the achievementlevels of females and minorities in science andengineering can match those of any other student.In other words, there are no inherent barriers toparticipation. The Federal role in intervention pro-grams is to encourage new starts, possibly to ex-pand funding, and to provide networks for theelements of successful programs to be dissemi-nated and shared. Some programs should bebased in schools, while others should not. Tai-loring each to the needs of specific populations,circumstances, and problems, is, in this domainas well as in many other areas of education, thekey to success.

Improving School Mathematicsand Science Education

Now when I say "education," I'm going beyond what is in NSF's Science andEngineering Education Directorate and looking at the education capabilitiesand programs of the foundation (NSF]. We have the responsibility to advancecapabilities along the whole educational pipeline. I don't think any other

agency, whether State or Federal, has that mission.

The American system of public schooling islarge, diverse, and stolid. Pressure to reform vari-ous features of the system, especially curricula,graduation standards, and the education ofteachers, has been building since at least the early-1980s, and some change, much of it led by theStates, has been realized. The "education reformmovement," as it is called, has drawn strength andencouragement from leaders in government, edu-cation, business, and higher education.' Much

'See, for example, National Commission on Excellence in Edu-cation, A Nation at Risk (Washington, DC U S. Government Pnnt-

of the pressure for reform has been bolstered byeconomic arguments, stressing the need for inter-national competitiveness and the industrial advan-tages of a well-educated work force.

THE SYSTEMIC NATURE OF THE PROBLEMSFACING AMERICAN SCHOOLS

The problems that face mathematics and sci-ence education in the schools are complicated andinterrelated. In the broadest sense of the term,they are systemic. Reforms of any one aspect ofmathematics and science teaching, such as course-taking, tracking, testing, and the use of labora-tories and technology, can and have been under-taken. But each change is constrained by otheraspects of the system, such as teacher training andremuneration, curriculum decisions, communityconcerns and opinions, and the requirements andinfluences of higher education.' Very little anal-

ysis has been undertaken of the costs and bene-fits of different kinds of improvements that couldbe made in mathematics and science education.A recent review suggested that schools':

. . . influence on learning does not depend on anyparticular educational practice, on how they testor assign homework or evaluate teaching, butrather on their organization as a whole, on theirgoals, leadership, followership, and climate. . . .

These organizational qualities that we consider tobe the essential ingredients of an effective schoolsuch things as academically focused objectives,

pedagogically strong principals, relatively autono-mous teachers, and collegial staff relationsdonot flourish without the willingness of superin-tendents, school boards, and other outside au-thorities to delegate meaningful control overschool policy, personnel, and practice to theschool itself. Efforts to improve the performanceof schools without changing the way they areorganized or the controls they respond to willtherefore probably meet with no more than mod-est success; they are even more likely to beundone.'

Incremental and Radical Reforms

Against this background, a case can clearly bemade for "starting all over" with a new systemof organizing, administering, and even fundingschools. The education system has evolved in-crementally, and, during the last 200 years, hasadapted to changing societal expectations, ex-panded its reach to almost the entire populationof students up to age 18, been influenced by thechanging economy of tne United States, and re-sponded to judicial intervention in many aspectsof its organization, including its financing. Thesechanges have been made on the superstructu ofexisting culture and practices, and have not nec-essarily resulted in the "best" system. But start-ing all over is not practical or politically feasible:too much is invested in the -urrent system ofmathematics and science education. The bestshort-term focus, therefore, will be on incremertalimprovements within the existing system.4

In 1985, Congress asked the National ScienceFoundation (NSF) to commission a special studyof investment options for NSF to undertake in sci-ence and mathematics education. The contractor,SRI International, was asked to identify specificniches that the Science and Engineering EducationDirectorate of NSF could fulfill, given the exist-ing structure, experience, and expertise of theAgency. The report of this study, published in

'John E. Chubb, "Why the Current Wave of School Reform WillFail," Public Interest, No 90, winter 1988, pp 28-49 Also see PeterT Butterfield, "Competitiveness Plank SevenEducation The Foun-dation for Competitiveness," Making America More Competitive(Washington, DC. The Heritage Foundation, 1987), pp. 69-76

'For the perspective of the former Secretary of Education, seeWilliam J. Bennett, American Education Making It Work (Wash-ington, DC U.S. Department of Education, April 1988), esp pp23, 31, 35, 41, 45.

June 1987, makes many concrete suggestions ofways NSF could use its special experience and ex-pertise.' Ten current areas for future NSF invest-ment are listed in box 6-A. The SRI report alsodiscussed the trade-off between incrementalchange and wholesale renovation, arguing thatwhile incremental improvements may not be theway to effect fundamental change, far-reachinginnovations in science education not grounded inthe current elementary and secondary school sys-tem will simply not be adopted.'

For now, incremental reform is the likely wayAmerican mathematics and science education willbe improved. The remainder of this chapter ex-amines some improvements that are taking placeand others to be contemplated, against the back-ground of intersecting local, State, and Federalinterests.

Local and State Initiatives

Local and State initiatives could go a long waytoward improving elementary and secondarymathematics and science education. Much can beand is being done to improve mathematics andscience education at the local level of the schoolboard and the school, from introducing magnetprograms to re-equipping science facilities.

The many different initiatives spawned byschools and school districts are difficult to sum-marize because they do not form part of a singleState, regional, or national plan. This does notdetract from their importance; they can be highlybeneficial. In 1983, the American Association ofSchool Administrators (AASA) sent a question-naire to 1,500 school administrators, mainly su-perintendents. From these and other data, AASAcompiled a list of the top 10 most common ac-tions already being taken by school districts toimprove mathematics and science education. (Seetable 6-1.)

Box 6-A. Opportunities for Future Investment in K-12 Mathematics and Science Education:Recommendations by SRI International to NSF's Science and Engineering Education Directorate

Opportunities to Devising Appropriate Content and ApproachRedesign and improve existing mathematics curricula at all grade levels. The amount of repetitive com-putation should be reduced, and the amount of effort devoted to other topics, such as the skills of mathe-matical problem solving, probability and statistics, and computer sciences, should be expanded.Redesign the way in which elementary school science is taught. Elementary school science, despite NSF'sattempts in the 1960s to develop "hands-on" curricula, is still very limited in scale and depth. NSF hasbegun an initiative in this area.' Similarly, one priority should be to redesign and improve middle andhigh school curricula.More effort should be made to match mathematics and science education with the needs and backgroundsof students, particularly females and minorities. The reach of existing programs and curricula must beextended, but experiments are also needed to tailor teaching to the special needs of each type of learner.

Opportunities to Strengthen the Professional CommunityThe people who assist mathematics and science teachers, such as lead teachers, curriculum specialists,and science and mathematics coordinators, need more help and support. Multiyear training programs,recognition programs, and development of stronger alliances between higher education and school dis-tricts would enhance this support function.The number training to become mathematics and science teachers needs to be increased, and their train-ing improved. NSF could enhance the "professionalization" of the teaching force, the content of teachertraining courses, and the utilization of knowledge about teacher recruitment and training programs.Strengthen the informal science education community. Educators out of schoolson television and inmuseums and science centersare becoming increasingly important. These people need training and profes-sional development, and would benefit from larger networks and closer collaboration.

Opportunities to Leverage Key Points in Educational InfrastructureImprove and expand publishing capabilities in mathematics and science education. An emphasis onbroadening the base of learners will require new and different teaching materials: current materials arelargely aimed at the "science- and engineering-bound." Collaborative programs with existing publisherswould help improve the textbook publishing process, and promotion of alternative publishing routeswould help provide a diversity of materials that the current mechanisms of market operation are notable to support.Improve testing and assessment methods and practices in mathematics and science. The growing powerof testing over curricular and teaching decisions indicates the urgency of developing and implementingtests that measure a broader range of skills, concepts, and attitudes than current fact-oriented tests. NSF'sskill at research and development gives it special expertise in managing research programs in testing.Work with State mathematics and science education reform leaders. Interest among these leaders in im-proving the teaching of these subjects is strong, but their familiarity with the educational issues involvedis limited. NSF could assist State-level groups to devise and implement reforms, and to develop networks.Expand the proven power of informal education programs and assist their assimilation into schools. Theseprograms are effective at reaching and motivating large and diverse groups of students. Innovations areneeded, as is better outreach to more communities.

'The National Science Foundation's first solicitation in this area, in fiscal year 1986. addressed elementary mathematics curricula, and resulted insix awards. A second solicitation, also in fiscal year 1986, addressed elementary science curricula and aimed to develop partnerships among pub-lishers, school systems and scientists/science educators for the purpose of providing a number M competitive, high quality alternative science programsfor use in typical American elementary schools " Among these latter awards has been the Technical Education Research Center's protect in linking com-puters and science learning A third round of awards was made in May 1988 See National Science Foundation, Directorate for Science and EngineeringEducation, "Summary of Grants, FY 1984-86.

Education policy begins at the local level.

States are playing an increasing role in K-12education, through finance, curriculum andgraduation requirements, and assessment andmonitoring. Most States are funding a growingproportion of the cost of public elementary andsecondary education (see figure 2-1 in ch. 2),spurred by the warnings contained in the rash ofeducational reform reports of the early 1980s.7This activity has been chronicled in recent sur-veys by the Education Commission of the Statesand the Council of Chief State School Officers(CCSSO)°

These two reports document the ways in whichStates have become more active in four areas:

curriculum requirements;assessment of the extent to which curriculum

Table 6.1. Summary of Kinds of Local Initiatives toReform K-12 Mathematics and Science Education

The 10 most common and frequent actions being taken byschool districts:

1. Revise, reconstruct, and strengthen the science and mathematics curricula. Committees are at work discarding oldcontent, adding new units, and expanding the scope andsequence in established and new offerings. A major aimis to bring about an articulation of offerings, in kinder-garten through grade 12.

2. Generate new activities to retrain, reeducate, and lend ahelping hand to classroom practitioners. Inservice edu-cation, in doses more massive than ever before, goes onat an ever-increasing pace within school systems and oncollege campuses. Cooperation with colleges and univer-sities is at a high level on behalf of both science and math-ematics.

3. Modernize and expand facilities needed for science, pro-viding better-equipped laboratories for upper grades, andoffering teachers suitable working space for elementaryhands-on science activities.

4. Make available new textbooks and other instructional ma-terials for science and mathematics. They buy "packagedprograms" (STAMM, COMP, SCIS, ESS), but, above all,districts develop their own curriculum guides, teacher re-source handbooks, and units for studentsall geared tolocal district philosophy, aims, and objectives.

5. Raise requirements for the study of science and mathe-matics, often under the spur of State legislation, at timesby decision of boards of education. The big push is towardmore years of science and mathematics at the second-ary level, and more time spent on task in the elementarygrades.

6. Monitor science and mathematics programs more closelythan ever before. They assess, evaluate, and measure.Methodology, content, and student achievement areunder close scrutiny at all times by principals, but moreoften by specialized personnel using new tools and in-struments.

7. Go into partnerships with industry, higher education, andcommunity groups. Out of these cooperative effortsalso called alliances and consortiumscome advancedcontent (from scientists and mathematicians); new oppor-tunities for inservice education (from colleges and univer-sities); and greater support for science and mathematicsprograms (from community and civic groups.)

8 Devise new programs to attract and hold students whohave so far been largely bypassed by science and math-ematics educationBlacks, Hispanics, American Indians,and other minorities.

9. Support, with greater interest than ever before, extracurricular activities for science and mathematics students.They seek the establishment of clubs and encouragegreater student participation in science and mathematicsfairs, olympiads, and other competitionsboth for theable and the average student.

10 Seize the role of advocacy, sensing this is the time andopportunity to rebuild and strengthen the science andmatnematics curriculums

requirements are met;providing special programs for female, mi-nority, gifted and talented, handicapped, andlearning disabled students; andrecruitment of mathematics and scienceteachers and improvement of their skills.

Most of these initiatives are too recent to havebeen evaluated, and it is difficult to say which areeffective and which not. CCSSO is developing aset of indicators for mathematics and science edu-cation to allow State-by-State comparison as wellas national evaluation of trends.'

There is increasing corporate support of K-12mathematics and science education, but its over-all amount remains very small compared withpublic spending." Industry can also contributevaluable resources in kind, such as equipment,trained scientists and engineers, and site visits.Much of this attention is driven by industrial con-cerns about the poor quality of high schoolgraduatesthe entry level work force to manyfirmsrather than the question of who will be-come scientists and engineers.

Course and Curriculum Requirements

States are trying to control and expand whatstudents learn by means of curriculum require-ments, tightened graduation requirements, andencouragements to teachers and students to ad-dress higher order thinking skills. With respect tograduation requirements, anecdotal data suggestthat college admission requirements may be moreimportant than State policies for the college-bound in science and engineering. Indeed, the

trend toward tightening graduation requirementsmay actually be deleterious for this group, bystretching existing teaching resources in mathe-matics and science too thinly.

Many States have begun to issue reasonablydetailed curriculum guidelines, and a few, suchas California, have comprehensive guides builtaround an integrated approach to curriculum de-velopment, textbook adoption, and teacher train-ing. Curriculum guides in mathematics and sci-ence are used by 47 States; most of these guidesare not actually mandatory for school districts.Policies on the amount of time that should bedevoted to mathematics and science in elemen-tary schools have been adopted by 26 States. Ofthese States, most recommend, but do not require,that about 100 to 150 minutes per week be spenton K-3 science, and 225 to 300 minutes per weekbe spent on K-3 mathematics. For grades four tosix, normal recommendations are 175 to 225 min-utes per week on science and 250 to 300 minutesper week on mathematics. (See table 6-2.)"

All but seven States (and all but four of the fullyconstituted States) set formal requirements for theaward of a high school graduation diploma. (Seetable 6-3.) (The Constitution of Colorado ex-plicitly forbids the State from setting such require-ments.) Almost all of the States that do set for-mal requirements have, since 1980, steadilyincreased the number of mathematics and sciencecourses that students must take. Of 47 States thatset requirements, 36 require 2 courses in mathe-matics and 39 require 2 courses in sciences. Dela-ware, Florida, Guam, Kentucky, Louisiana,Maryland, New Jersey, New Mexico, Pennsyl-vania, and Texas each set a higher standard, re-quiring at least one more mathematics course fora total of three.

However, control of the number of mathe-matics or science courses alone is a relatively bluntpolicy tool, for it disregards tht. curricular con-tent of those courses. In addition, mandating ex-tra courses in mathematics and science will be oflittle use if there are too few well-qualified teachersavailable to teach them. Indeed, some argue thatincreasing graduation requirements may actuallyharm the college-bound in science and engineer-ing, for teachers of the specialized courses thatthese students now take will be transferred toteach more mainstream courses." Schools withalready poorly equipped science laboratory facil-ities will be asked to spread thin resources eventhinner. Thus, tightening graduation requirementsmust be part of a balanced strategy that also pro-vides adequate teaching and facilities for the new-iandated classes in mathematics and science.

FEDERAL INVOLVEMENT

The Mis-souri Mastery and Achievement Test, for exam-pie, has been designed to include items that as-sess higher order thinking skills. Higher orderthinking, although much sought after, is difficultto define and there appears to be little agreementon how it can be taught.

Statewide testing programs are used in 46States, indicating a broad response to the publicpressure for accountability. But only 30 of theseStates include science knowledge in these tests,whereas 43 include mathematics. Five States(Alaska, Montana, Nebraska, Ohio, and Ver-mont) delegate responsibility for assessment toschool districts or schools themselves. A recentOTA survey found that 21 States now 7-Nuke stu-dents to pass a minimum competency test in des-ignated basic skill areas prior to graduation.

the Northwest Ordinance of 1787, the Govern-ment has indirectly supported education throughfinancial and land contributions. In 1862, whenthe U.S. Office of Education was established, thatrole was augmented by the task of informationgathering, research, and analysis. At the turn ofthe century and for the next 20 years, in responseto the increasing industrialization of the Nation,the Federal Government began to take an interestin manpower needs and training and, under Fed-eral law, sought to promote vocational training.

The Federal Interest in K-12Mathematics and Science Education

Large-scale Federal funding of basic research be-gan after World War II, when demand for re-search scientists and engineers was strong. NSF,

116

created in 1951, was given a mandate to ensurethe adequacy of science and engineering educa-tion and manpower at all levels. NSF's prime edu-cation goal, however, was the cultivation andeducation of enough scientific talent to fuel thenew research-intensive industries and national lab-oratories. Ever since, NSF has made a significantcontribution, by leadership and funding, to sci-ence education, but skewed toward students des-tined for science and engineering careers.

Serious concerns about the adequacy of math-ematics and science education developed in themid-1950s, as Cold War competition with 'heU.S.S.R. and the baby boom population strainededucational resources. Significant NSF involve-ment in science education, however, originatedwith the "Sputnik crisis" of the late-1950s. TheNational Defense Education Act of 1958 was abold new law to bolster supplies of scientific andother skilled manpower. The act gave grants toschool districts to improve or build laboratory fa-cilities and sponsor teacher training in mathe-matics and science, as well as foreign languageinstruction. Congress increased funding for sci-ence education at NSF, to the point where edu-cation was apportioned at about one-half of NSF'sbudget.' The 10 years following Sputnik werethe "golden years" of NSF's mathematics and sci-ence education effort, highlighted by funding forteacher training institutes, curriculum develop-ment, informal education, and research partici-pation programs for high school students and theirteachers.

Federal funding for education in all subjectsreached its zenith in the early-1960s, when anxi-ety about regional, economic, and racial dispari-ties in educational provision led Congress to adoptambitious programs of support for underpriv-ileged students. The Federal role in promoting eq-uity became generally accepted as a consequenceof the implementation of these programs, whichwere successful in achieving their limited goals.'

The Reagan Administration's policy of dimin-ishing, if not removing, Federal involvement ineducatie n was enacted by major cuts in educa-tion programs at the beginnning of the 1980s. Fed-eral support fell from about 8 percent to 4 per-cent of total national education expenditures. The"new federalism" ideology held that funds wereto be apportioned among States on an entitlementbasis; States should be allowed to spend funds asthey saw fit, and not necessarily in accord withany Federal policies or programs." In 1981-82,the Science and Engineering Education Directorate(SEE) of NSF was disbanded. However, this lat-ter move was most unpopular with mathematicsand science educators and in 1983, under pies-sure, the SEE Directorate was resuscitated.'

By 1984, continuing anxiety about internationaleconomic competitiveness and the apparentlypoor quality of public schooling led Congress topass the Education for Economic Security Act(EESA), designed to promote teaching of mathe-matics, science, and Foreign languages. Title II ofthis act directs the Department of Education toprovide grants to school districts and States to im-prove the teaching of mathematics, science, com-puter science, and foreign languages that are crit-ical to national economic well-being. Althoughthe Administration has proposed extending thecriteria for funding under this program to all sub-ject areas, this proposal has not been supportedin Congress. Title II was part of the package ofeducation programs reauthorized in 1988; the newname for Title II is the Dwight D. EisenhowerMathematics and Science Education Act."

funding and considerable bipartisan support, evenin the current stringent budgetary climate. Theycome from three sources:

NSF, which is generally recognized as thelead agency for mathematics, science, andengineering education;

the Department of Education, which hasoverall charge of Federal education pro-grams, but within which mathematics andscience education is a relatively low priority;and

mission agencies that have a direct interestin developing a pool of skilled scientific. tal-ent; such agencies include the Department ofEnergy (DOE), the Department of Agricul-ture (USDA), the National Institutes ofHealth (NIH), and the National Aeronauticsand Space Administration (NASA).

There is an important difference between NSFand the Department of Education in the scale ofthe programs that each mounts. Whereas NSF'sentire budget is now somewhat under $2 billionannually (and is principally spent on research),that for the Department of Education is about $20billion. Although most of the Department's pro-grams provide funding either on a categorical ba-sis to providers of education or to ensure equi-table access to education, the Department has oneprogram specifically addressed to K-12 mathe-matics and science education: Title II of the EESA.Appropriations for Title II have been compara-ble to NSF spending on precollege education, butrepresent only a few percent of the entire spend-ing of the Department of Education. The dollars,however, are distributed to the States in a for-mulaic way, with little technical assistance to im-plement their use or monitor their impacts. Nospecial interest in programmatic mathematics andscience education at the Department of Educationis apparent.

Some argue that mathematics and science edu-cation programs conducted by NSF might flour-ish were they relocated in the Department of Edu-cation. Proponents say that the Department ofEducation would not concentrate only on tl-brightest and best students and on funding pro-posals from rich research universities the way NSF

does.21 In audition, some note that NSF is mostcomfortable in dealing with and through univer-sities and, until recently, has made few efforts towork closely with States and school districts, asfavored by the Department of Education. NSF isnow attempting to improve its working relation-ships with the States. Giving a greater role to theDepartment of Education in mathematics andscience education programs is rejected by mostof NSF's existing clients in the scientific and sci-ence education research communities, amongwhom the Department of Education has littlecredibility."

Consideration of the propriety of Federal edu-cation programs is, at riot, a highly ideologicalbattle and invokes constitutional concerns. Froma public policy perspective, it is important to ex-amine whether and how Federal funding of math-ematics and science programs changes the actionsthat State and local bodies would otherwise havetaken. Do Federal programs merely replace fundsthat would otherwise have been raised by Stateand local sources or do they allow States and lo-cal school districts to do things that they wouldnot or could not otherwise do7 Conversely, doFederal programs merely encourage States and lo-cal school districts to avoid reforming their ownoperations, including possibly raising local andState taxes?

There are no clear answers, but Federal pro-grams may work best when they identify aspectsof the K-12 education system that have fallenthrough the cracks of the different agencies in-volved in education, and address those aspectsdirectly. For example, the "Great Society" legis-lation of the 1960s improved educational provi-sion to poor and disadvantaged children, and theNational Defense Education Act was successfulin supplying science equipment and teacher train-ing to school districts.

NSF's Role in Science andEngineering Education

NSF has been the lead Federal agency in pre-college science and mathematics education sincethe agency's inception. NSF in recent years hasbeen ambivalent towards science education."With its limited funding of K-12 programs, NSFaims to be a catalyst for interplay between theresearch community :ind schools and school dis-trictsto generate new ideas for others to imple-ment; to leverage its funding through States,school districts, and foundations; and to do re-search on mathematics and science education. Inits 1987 study, SRI International suggested thatNSF's approach to K-12 mathematics and scienceeducation should be based on three principles:

identifying targets of opportunity that are im-portant problems and amenable to NSF's in-fluence;supporting core functions of professional ex-change amcng scientists, engineers, teachers,and education researchers; data collection;and experiments in education; andinvesting as part of a coherent strategy tobroaden the base of science learners.

The SRI report identified six characteristics ofthe SEE Directorate that distinguish it from otheractors:

national purview of problems and solutions;quasi-independent status rather than an ex-ecutive branch department;connection to the mathematics, science, andengineei ing communities;large amounts of discretionary funding (i.e.,those that are allocated on a project/proposalbasis);a central position vis-a-vis various actors in-volved in improving mathematics and scienceeducation; andan established track record in K-12 mathe-

matics and science education programs, espe-cially at the secondary level."

NSF also attempts to define a leadership rolein mathematics and science education issues, afunction which, especially in the decentralizedAmerican education system, should not be under-estimated. The ongoing challenge for NSF inscience and engineering education will be locat-ing particular niches where it can make a usefuland detectable difference, rather than being anagent of change on a broad scale. Investments bythe SEE Directorate in science and mathematicseducation must differ from support for science andengineering research. Developing NSF's capabil-ity to invest strategically in education programsmay take 5 to 10 years.'

Evaluation of Federal Science andMathematics Education Programs

Too little is known about the effectiveness ofprevious and current Federal efforts to improveelementary and secondary mathematics and sci-ence education. Evaluation of these efforts, fora number of reasons, is very difficult. (See box6-B.) This review has been supported by an in-formal questionnaire survey of members of theNational Association for Research in ScienceTeaching (NARST), an association of universityresearchers in mathematics and science educationthat aims to improve teaching practices throughresearch. Many Federal programs in this area havebeen tried, and appendix C lists some of them.Most have emphasized science rather than math-ematics.

Three principal Federal programs have been de-signed to improve mathematics and science edu-cation:

NSF-funded teacher training institutes;NSF-funded curriculum development; andTitle II of the EESA, administered by the De-partment of Education.

In a diliiinn, in'oblens in reaching etittclueions that are of national relevance arise from the difficultyevaluatorihriiin gaining access to already-belesguered schools to study programs, and from the expenseof doing national evaluations of the worth of particular programs. Schools are increasingly reluctant toallow researchers access to classrooms, since they feel that they are asked to provide too much informationalready, with too much of it beingused against them. Thesefacton sometimes lead researchers to use smallsamples chosen from unrepresentative school environments for their studies, which diminish the force ofresearch findings. Sometimes researchers argue that the results can be extrapolated to much larger popula-tions, but that argument can only be sustained when other characteristics of the populations, such as socio-economic status, ethnic composition, and urbanicity of the school chosen, are matched.

NSF Teacher Training Institutes Program

Between 1954 and 1974, NSF spent a total ofover $500 million (or over $2 billion in 1987 dol-lars) on teacher training institutes, most of themfor secondary school teachers.27 These institutescame in several forms. Most were full-time sum-mer programs, others part-time after-school pro-grams, and others full-time academic year pro-grams. Some were aimed at high school teachers,others at elementary and middle school teachers,and others at science supervisors. At that time,the consensus was that the teaching force was defi-cient in content knowledge about science, and

vol 1, p 133 Expression in 1987 dollars is an OTAestimate

most of the institutes focused on improvingteachers' knowledge about science, largely bymeans of lectures. Few of them addressed teach-ing practices. Most institutes were based at col-leges and universities, which organized the pro-grams and paid teachers stipends and travelexpenses for attending.

By today's standards, the model that these in-stitutes adoptedthat giving mathematics and sci-ence teachers better subject knowledge would leadto better teachingseems rather primitive. Anyreplication of these institutes would now focus onachieving a balance between knowledge and ex-perience of how to teach science and mathematicstogether with what to teach. Nevertheless, evi-

dence suggests that the former mathematics andscience teaching force was so poorly endowedwith subject knowledge that emphasis 3n contentover practice was largely inevitable.

At their peak in the early-1960s, about 1,000institutes were offered annually, each with be-tween 10 to 150 teachers meeting over a 4- to 12-week period; just over 40,000 teachers werereached annually (about 15 percent of the highschool mathematics and science teaching force).The institutes were reorganized in 1970, by whichtime NSF had judged that the institutes hadreached about as many teachers as any voluntaryprogram ever would. A survey taken in 1977found that many teachers had participated in NSF-funded institutes. The survey indicated that nearly80 percent of mathematics and science supervi-sors had attended an institute, as had 47 percentof science teachers and 37 percent of mathematicsteachers of grades 10 to 12. Only about 5 percentof teacl-ers of kindergarten through third gradehad attended such an institute.

Improvement of the skills of the elementaryteaching force will always be difficult, becausethere are over 1 million individuals who teach atleast some element3ry mathematics and science(alorg with many other subjects), and becauseuniversity-based mathematics and science educa-tors generally find it harder to reach elementaryteachers than they do high school teachers. Forexample, it is estimated that NSF's current effortsreach, at most, 2 or 3 percent of secondary math-ematics and science teachers.28

Evaluation of the effects of these institutes hasyielded no consensus on their usefulness. Teacherswho participated are enthusiastic about them aneremember them as stimulating and professionallyrefresh;ng. The General Accounting Office re-viewed research on NSF-funded institutes andfound little or no evidence that such institutes hadimproved student achievement scores." WhereasNSF remains cautious in claiming effectiveness,

"Ibid., vol 1, pp 133-134Such a post hoc measure, however, may bear no relation to the

a priori goal of the institutes, namely, to update teacher's knowl-edz,t. See U.S. Congress, General Accounting Office, New Direc-tions for Federal Programs To Aid Mathematics and Science Teach-ing, GAO/PEMD-84-5 (Washington, DC U S Government PrintingOffice, Mar 6, 1984).

many science educators think that the instituteswere very successful. Various studies, includingone by the Congressional Research Service in1975, found that the institutes had positiveeffects.'

NSF did not attempt a systematic comprehen-sive evaluation of its own during the lifetime ofthe institutes. The institutes concentrated on im-proving the mathematical and scientific knowledgeof teachers, but there is no direct relationship be-tween teachers' knowledge, their effectiveness asteachers, and educational outcome measures suchas students' achievement test scores." In prac-tice, teachers need both some knowledge of math-ematics and science and some pedagogical skillsto be effective teachers.

Anecdotal evidence drawn from a history of thisprogram and from the OTA survey of NARSTmembers indicated that the teacher institutes pro-gram had these important effects:

It brought teachers up-to-date with currentdevelopments in science.It wrought teachers closer to the actual pro-cess of doing science and thereby improvedboth their identification with, and sense ofcompetence in, science.It helped teachers share common solutionsand problems, and gave them a network ofpeers that they kept in touch with many yearsafter the programs ended.It allowed teachers to do experimental workin science, which many of them had neverdone before, and thereby encouraged themto replicate this experience for their students.It helped define leaders for the science edu-cation community, who now are effectivevoices for this community in professionalmeetings and policy debates.

It recognized the importance of the w ork ofmathematics and science teachers.It inspired and invigorated teachers to faceanother year of teaching.

Among problems with the institutes, however,were the following:

Since teacher participation was voluntary,only those teachers who were the most in-terested and motivated in science teachingparticipated. The least interested and leastqualified shunned the program, which con-sequently reached at best only about one-halfof all teachers (though this is not an insig-nificant number).Since many of the institutes offered gradu-ate credit, the program helped subsidize stu-dents' progress toward master's and doctoraldegrees in education. Possession of thesedegrees may have helped impel good teachersout of active teach;r1g into administration,or into other jobs entirely.The institutes succeeded in conveying muchinformation about new developments in sci-ence, but gave teachers few clues as to howto teach this information to their classes.The institutes were typically lecture courses.

The costs of the teacher institutes were large,particularly for the academic year institutes, forwhich teachers were pulled from classrooms.Typical costs today for teacher institute programsare reported at about $25 to $40 per hour perteacher. If a minimum of 100 hours is assumedfor length of the institute to make it meaningful,for a total cost per teacher of about $3,000, itwould cost about $600 million to put all second-ary mathematics and science teachers through oneinstitute each .32

A small program of teacher institutes is nowfunded through the Teacher Preparation and En-hancement Program at NSF. In general, these putmore emphasis on teaching techniques in mathe-matics and science than did the earlier institutes.Evaluations of these institutes indicate that theyare having some success.33

Any future replications could build on success-ful NSF-sponsored models for inservice education,and would need to be based on a stronger part-nership between school districts and universitiesthan existed 20 years ago. Alternatively, NSFcould try to act as a catalyst, persuading Statesand school districts to fund such inservice edu-cation directly?' Either way, the school must berecognized as the appropriate unit; teachers aloneare neither the problem nor the solution. Or-ganizational change is needed, and that impingeson all aspects of the system, from the classroomand school administration to the local district andState jurisdictions.

NSF-Funded Curriculum Improvements

In the 1960s and 1970s, NSF spent about $200million on over 50 curriculum reform efforts.Their main focus was on the sciences rather thanmathematics, and the new curricula have had asignificant impact on the science education ofmany students.

To protect against Federal domination of cur-riculum, NSF did not review these projects oncecompleted and ensured that the materials wereheld and disseminated by the developer ratherthan by NSF. Nevertheless, a fifth grade socialstudies curriculum, "Man: A Course of Study,"attracted considerable criticism and congressionalscrutiny in 1975; some critics found it offensiveand unacceptable for children. NSF has since beenextremely cautious in curriculum developmentever since.

The curricula were almost all developed byteams headed by scientists, but often involvedmathematics and science educators, and generaleducators; they were largely designed to conveythe content and structure of the separate scien-

Or the National Science Foundation could concentrate on de-veloping a smaller number of lead mathematics and science teacherswho would then enthuse the remaining teacher force. This latterstrategy is advocated in the recent SRI report, primarily becauseof the cost and difficulty of organizing another mass program toreach all mathematics .i.,LI science teachers Such a program, how-ever, would focus change one further step away from students' ac-tual learning about mathematics and science than even the teacherinstitute program would See Knapp A al., op at , footnote 5, p.135

tific disciplines." Many believed that the highschool curricula were too demanding, however,and worked well only for those planning collegemajors in science and engineering. Many believedthat the scientists 'lominated the projects and thatfeedback on the new materials was not sought.

In 1968-69, it was estimated that nearly 4 mil-lion students (about 10 percent of the total) wereusing some kind of NSF-funded curriculum ma-terials. A 1977 survey found that about one-halfof the science classes in grades 6 to 12 were usingsuch materials, although only about 1C percentof mathematics classes in these grades were."NSF recently reinstated curriculum development,and is funding a series of three-way collaborativeprojects (involving publishers, universities, andschool districts) to develop elementary science cur-ricula.

Research reflects a consensus that the new cur-ricula worked quite well. A review of evaluationstudies found that, compared to control groups,students taking new curricula scored higher onachievement tests, had more positive attitudestoward science, and exhibited fewer sex differ-ences in these attributes. Students taugh byteachers who had been through preparatoryteacher institutes for the curricula scored morehighly than their peers taking the new curriculawithout this benefit." It is clear that successfulimplementation of new curricula is very closelytied to teacher training; curriculum projects areof little use without support for teachers to mas-ter the new curriculum and put it into practice.Earlier elementary science education curricula,such as the Science Curriculum ImprovementStudy (SCIS), Elementary Science Study (ESS),and Science: A Process Approach (SAPA) did net

become , -11 established in schools largely becauseteachers were ill-prepared to teach them.'

Among the positive effects of new curriculawere a spill- over effect to the entire mathematicsand science curriculum, such that traditional text-books from commercial publishers began to adoptmany of the techniques, such as hands-on science.The main NSF-funded mathematics curriculum,the School Mathematics Study Group, explicitlyaimed at affecting publishers' own curricula ."

The success of new curricula is partially at-tributed to the considerable research that wentinto them. Many are still in use in some schools;they have influenced teachers and textbooks eversince. Many teachers have extensive experiencewith these curricula, and now know how to avoidsome of the problems that the curricula can cause.

NARST members particularly cited the Biologi-cal Sciences Curriculum Study (BSCS), the ESS,the SAPA, and the SCIS (the last three beingelementary science curricula), as effective and val-uable curricula. Many of these curricula haveapparently been translated and adopted for usein schools in South Korea and Japan. It has beenestimated that the BSCS has been used in aboutone-half of all biology classes in the United States.One-quarter of those who graduated with a bac-calaureate degree in physics in 1983-84 had takenBSCS physics in high school."

Problems cited with these curricula included:

A lack of adequate financial and moral sup-port to teachers introducing the new cur-ricula.A focus on "pure" science rather than its real-life applicability.A design with only the future scientist andengineer in mind, which frustrated largenumbers of mainstream students.A domination by research scientists ratherthan science educators, precluding develop-

ment of a needed team approach to the de-sign and implementation of the curricula.An approach embracing a view of science asa collection of neutral and immutable facts,to the exclusion of other conceptions ofscience.

Today's science curricula have slipped back intostressing facts at the expense of reasoning and un-derstanding. One approach to future science cur-ricula might be to disregard traditional discipli-nary boundaries in science, and focus on hybriddisciplines or unifying themes and ways of ob-serving and measuring. Many science-intensiveschools integrate science with mathematicscourses, an innovation that could be followed bymost schools. In any case, the design of new cur-ricula requires the active participation of the rele-vant scier.tific research communities."

Mathematics curricula also need to be im-proved. Less emphasis needs to be placed on tradi-tional rote learning. The curricula coi'id concen-trate on new developments in mathematics andits applications, such as mathematical problemsolving, probability and statistics, and computerscience. Deficiencies of mathematics curriculahave been demonstrated by data collected for theinternational comparisons of achievement.'Curricula need to reflect the availability of thehand-held calculator. One example of a reformin progress is the new Mathematics Frameworkfor California Public Schools, whi .:i encouragescalculator use from primary grades upward.

Title II of the Education for EconomicSecurity Act of 1984

Title II of the EESA (Public Law 98-377 asamended by Public Law 99-159 and Public Law100-297) --as a major congressional initiative toaddress the problems apparent in mathematicsand science education in the early-1980s.

instruction in mathematics, science, computerlearning, and foreign languages in both public andprivate schools. Title II established teacher train-ing as first priority and directed that the fundsallocated to school districts must be spent on train-ing. Only if school districts demonstrate to Statesthat there is no further need for such training cansuch funds be used for other purposes, such asequipment and materials purchases or training inforeign language or computer instruction.' Thelegislation also contains provisions intended toboost the participation of "underrepresented" and"underserved" groups. The legislation was reau-thorized in 1988 (Public Law 100-297), and re-named the Dwight G. Eisenhower Mathematicsand Science Education Act.

Title II has been funded unevenly by Congress:$100 million was appropriated in fiscal year 1985,$42 million in fiscal year 1986, $80 million in fis-cal 1987, and $120 million in fiscal year 1988. Forcomparison, the total expenditure on public andprivate elementary and secondary education in1986 was about $140 billion; the total spendingon mathematics and science teacher training wasprobably about $500 million to $1 billion. Totalspending by the Department of Education was$19.5 billion in fiscal year 1987 (so that Title IIwas a small portion of the Department's total ef-fort). Another way of evaluating spending on Ti-tle II is to recall that, nationally, a $40 millioneducation program equates to a spending of $1per pupil or $20 per teacher.

The Department of Education's implementationof Title II has been slow. Although funds for fis-cal 1985 were provided by Congress, grant awardswere not announced until July 2, 1985, immedi-ately after the end of the school year (effectivelydelaying implementation by 12 months). How-ever, the Department now hosts regular meetingsof State Title II coordinators and publishes someinformation on exemplary State and local pro-

the remaining 1 percent is divided equally betweenthe U.S. Territories and Insular Areas and theU.S. Bureau of Indian Affairs. Each State mustsubmit a plan for the use of the funds to the Sec-retary of Education before the State's allocationcan be released.

The States' 90 percent allocation is dividedamong the States (including Puerto Rico and theDistrict of Columbia) on the basis of the size oftheir school-age populatiorI, with the proviso thateach State must receive at least 0.5 percent of thetotal appropriation. Of the sum that each Statereceives, 30 percent must be given directly to theState's higher education agency (primarily forelementary and secondary teacher training pro-grams), leaving 70 percent to be allocated by theState education agency for elementary and sec-ondary education (no more than 5 percent of eachof these allocations can be used for State admin-istrative costs). Of the funds given to each State'seducation agency, 70 percent must be dividedamong the school districts, giving equal weightto the size of the total public and private school-age population and the number defined as "dis-advantaged" under the Chapter 1 program of theEducation Consolidation and Improvement Actof 1981. The 30 percent share of funds intendedfor element: Ty and secondary education that isretained by the State must be spent on exemplaryprograms in teacher training and instructionalequipment, including those designed specificallyto benefit the disadvantaged or the gifted, and ontechnical assistance to school districts.

Of the sum allocated to the Secretary's Discre-tionary Fund, 25 percent must be awarded tohigher education for use in foreign language in-struction improvement, and 75 percent must bespent on competitive awards for speciil programs.So far, two competitions for this fund have beenheld, awarding $5 million. In these competitions,special consideration must be gii en to magnetschooi programs for gifted and talented studentsand for historically underseived groups in scienceand engineering.

The net effect of the Title II legislation is to dis-perse appropriated funds very widely withoutconsideration of whether dilution reaches a thresh-old where the funds make no discernible impact

133

on mathematics and science education. Almostall school districts in the Nation have receivedsmall amounts of these funds; the problem is thesize of the allocation. One-half of all the annualgrants made to school districts under Title II werefor less than .4.1,000 and one-quarter were for un-der $250; some districts have refused to apply forthe funds, citing the desultory amounts of moneythat they would get as a result.* Most State Ti-tle II coordinators do not collect detailed data onthe uses of these funds, but they believe that mostare used for inservice training and workshc ,s.Very little goes to support alternative certifica-tion and programs for training new teachers orteachers switching into science and/or mathe-matics.'

The legislation required States to justify theirneeds for this funding by providing needs assess-ments to the Department of Education, describ-ing their plans for upgrading teacher quality inmathematics, science, computer learning, and for-eign languages. Data yielded by these assessmentshave been of variable quality. CCSSO, with fund-ing from NSF, did attempt to encourage Statesto report their data using common formulae andtabulations, and about 33 States (mainly thesmaller States) supported this program. Congressrequired the Department of Education to provideit with a summary of the needs assessments in thefiscal 1986 NSF authorization (Public Law 99-159);the Department fulfilled this requirement in Sep-tember 1987, although this document itself notedthat it was of limited usefulness since the ". . . re-sulting needs assessment reports . . . are highlyidiosyncratic and do not readily lend themselvesto national generalizations.""

Data and Research Funded by theDepartment of Education and theNational Science Foundation

The Federal Government, through NSF and theDepartment of Education, supports a great dealof data collection and analysis, as well as educa-tional research an eval'lation that is relevant tomathematics and science education. The follow-ing programs are active:

Office of Studies and Program Assessment,NSF, providing data and management infor-mation on the national state of mathematicsand science education;Program of Research in Teaching and Learn-ing, NSF, funding educational research on ef-fective teaching and learning in schools anduniversities;Center for Education Statistics, Office of Edu-cational Research and Improvement (OERI),Department of Education, providing nationaldata on education in all subjects; andresearch programs in OERI, funding educa-tional research by individual investigatorsand centers, and its dissemination throughresearch and development (R&D) centers anddatabases, such as ERIC.

The overall system of data collection on math-ematics and science education would benefit fromgreater formal coordination between NSF and theDepartment of Education." The best work hasbeen done by NSF, particularly its two NationalSurveys of Mathematics and Science Education(in 1977 and 1985-86, respectively). But data onclass enrollments by sex, race, and ethnicity arenot available from the 1985-86 survey, and pre-liminary data on course-taking by high schoolgraduates from the National Assessment of Educa-tional Progress 1987 High School TranscriptStudy appeared late in 1987. A new Departmentof Education study, the National Educational Lon-gitudinal Study, officially began in 1988. It would

"Informal coordination has been practiced for a long time, In-cluding joint National Science Foundation (Science and Engineer-ing Education Directorate)-Department of Education review ofeducational research proposals (Richard Ben y, former National Sci-ence Foundation staff, personal communication, August 1988)

be valuable to have recent data to gauge the ef-fects of educational reforms.5°

Educational research in mathematics and sci-ence is in even more tenuous shape, however,having suffered (along with research in other sub-ject areas) from budget cuts," disputes amongseveral relevant disciplines (including psychologyand cognitive science), and a failure to pursuemore active development programs as well asbasic research." In particular, education re-search in mathematics and science is still recov-ering from the shutdown of NSF's SEE Directoratein the early 1980s.53 The key to better research,ultimately, will be better dissemination and de-velopment work that builds on the base of em-pirical knowledge. Data collection from States andschool districts should be improved by changesenacted by Congress during the recent reauthor-izat!on of Federal education Lgislation.

The Department of Education also runs the Na-tional Diffusion Network (NDN), established in1973, which disseminates and provides some fund-ing for implementation of curricula that are ofdemonstrated educational benefit. NDN programscover all levels of education, including higher edu-cation. By DecembEr 19.57, there were 450 pro-grams in NDN, and they were being used in about20,000 schools with 2 million students. Ten ofthese programs were in science, four of which hadoriginally been developed, in part or whole, withfunds from NSF. Recent programs had been de-veloped with Title II funds. NDN funds dissemi-nation of programs, and the average grant isabout $50,000 over 4 years.ss

Education Programs in theMission Research Agencies

Federal R&D mission agencies are active inmathematics and science education. The bulk ofactivity is in informal outreach programs, suchas classroom visits, NASA's Spacemobile, labora-tory open houses, career days, and science fairs.These programs touch tens of thousands of stu-dentsbut only to a small degree. Some Federallaboratories "adopt" a high school, and therebydevelop extensive contact with teachers and stu-dents. Adoption programs usually involve littleor no direct cost to the agency, since they relyon employee volunteers to speak at schools, judgefairs, or host a visiting school group. Becausethese kinds of programs are informal in nature,they do not have established budgets or staff atthe agency, and depend on the initiative of re-search staff as well as any education coordina-tors that the agency may have. They tend to waxand wane. Usually only a handful of people atany agency (including its field laboratories) workfull time on education.

A few agencies also have modest programs totrain and support mathematics and scienceteachers, ranging from summer research andrefresher courses to resource centers where theycan work with and copy instructional materials.None of the extensive teacher training workshopsreach more than a few dozen teachers, however.One exception is NASA's interactive videoconfer-ences on NASA's activities in space science edu-cation, which have drawn about 20,000 teacherseach time.

The other genre of program is in research par-ticipation or apprenticeships, which reaches onlya very few students but in much greater depth.These programs bring students, usually juniorsor seniors in high school, into agency laboratoriesfor research experience in ongoing mission R&D.

These research apprenticeships are powerfulmechanisms. For example, since 1980, the NIHMinority High School Student Research Appren-ticeship Program has awarded grants to univer-

sities and medical schools to bring students in fosummer research projects. Students participate inall aspects of research; they collect data, reviewliterature, attend seminars, use computers, andwrite up findings. In 1988, over 400 students willbe supported on NIH grants totaling $1.5 million.At the program's peak in 1985-86, 1,000 studentsparticipated each summer. Over half the partici-pants are Black; about 20 percent are Hispanic,another 20 percent Asian. Over half are female.Students are selected for aptitude and motivation,and on the recommendation of their scienceteacher."

Mission agency sum ner research programs to-gether support perhaps a few thousand highschool studentscertainly under 10,000but, inany case, more than NSF's comparable programdoes. Full-fledged programs cost on the order ofjust under $1,000 to around $3,000 per student.Most of the cost is in salary for the student; thereusually is significant cost - sharing with the hostlaboratory, and often with industry and other pri-vate supporter>. Shorter summer programs, wherestudents come in for a fevi weeks, or programsthat mix hands-on research with instruction or career sessions, are less costly per student (up to afew hundred dollars); they also provide a less in-tensive experience.

Mission agency education activities, mostly lo-cal and informal, complement to a large extentthe formal, research- oriented and nationwide pro-grams of NSF. The mission agencies are particu-larly successful at reaching diverse populations.The programs build on the existing agency staffand facilities; many make special efforts to reachfemales and minori.ies. Formal minority researchapprenticeships were established in 1979 by theOffice of Science and Technology Policy for themajor R &D agencies.

The mission agencies have unique strengths inreaching out to young science and mathematics

55The National Institutes of Health evaluation testifies to the suc-cess of the research apprenticeships in encouraging participants toattend college and pursue a research career; 60 percent of studentssay that the experience influenced their career decisions. One of thetouted strengths of the program is its flexibility and the institution'sleeway in awarding and using the grants (the grants include salaryfor the apprentice, which may also be used for supplies or any rele-vant education activity) National Institutes of Health, personal com-munication, May 1988.

students. Federal research laboratories around thecountry are a particularly valuable resource foreducation, with unique facilities and equipment.DOE and NASA have large, visible laboratoriesdoing state-of-the-art research in exciting areassuch as space flight, lasers, the environment, andenergy. Many of these laboratories are in areaswhere there is little of nothing else in the way ofsophisticatEd research ilcilities. There is no placeelse students (or teachers) can see, touch, andwork with equipment like rocket engines, whetherit is for an afternoon visit or a summer of research.The thousands of researchers at these laboratoriesare likewise a valuable resource, offering inspi-ration, expertise on careers and nearly any spe-cial area of research, real-life role models foryoungsters, and mentors for students doing re-search.

The ethos behind mission agency education ef-forts is to improve the quality and coverage ofelementary and secondary education in their mis-sion area and ultimately to help ensure an ade-quate supply of scientists and engineers workingboth for the agency and in areas that support theagency's mission. (See table 6-4.)

sons. An educational affairs division was formallycreated in 1986. NASA supports elementary andsecondary teachers with workshops and resourcematerials at NASA's field centers. NASA is alsoreviewing and supplementing existing curricula,and has produced videotapes, satellite broadcasts,videodiscs, electronic tutors, and other innova-tive educational technologies. NASA has a sum-mer high schou; apprenticeship, which employsabout 125 students, most of them minority. Inaddition, about 30 full-time education outreachstaff (mostly former teachers) spend over 160 dayson the road with the Spacemobile (a mobile re-source center for children about the space pro-gram), presenting school assemblies and class

DOE, in cooperation with its national labora-tories, has one of the most extensive programs forstudent summer research among the Federal agen-cies. It has several programs, for example, the highschool honors research program (320 students,$550.000), and minority student research appren-ticeships (200 students, $120,000).

laboratories as part of a university-laboratory co-operative program.

DOE and the Department of Defense (DoD) arethe only agencies with substantial involvement inearly engineering education. The prefreshmanengineering program (PREP) awards money touniversities to sponsor summer programs for fe-males and minorities in junior high and highschool. PREP programs include research experi-ence, instruction, and career and college prepara-tion. It reaches 2,000 students ($300,000), andbenefits from substantial cost sharing and in-kindsupport.

Various offices of DoD support UNITE (Unini-tiates Introduction to Engineering), which rangefrom short stays to many-week research appren-ticeships on engineering campuses. UNITE ses-sions include engineering and other technicalclasses, planning for college, career semir,rs,visits to military laboratories and facilities, andmeetings with military engineers. Extensive fol-lowup of students shows that the program works.Students report that it helped shape their careergoals; it turned some off, but it turned many moreon to engineering. (UNITE is a military offshootof programs sponsored by the Junior Engineer-ing Technical Society, or JETS, a private orga-nization with extensive corporate support. JETScoordinates Minority Introduction to Engineer.ing programs to introduce students to engineer-ing and college, most often as 1- or 2-week sum-mer programs at universities.) The Research inEngineenng Apprenticeship Program pay: severalhundred high ,chool students to do mentoredsummer research at defense laboratories.

The National Institute of Standards and Tech-nology (NIST), formerly the National Bureau ofStandards, is a relatively small agency with fewregional facilities. However, it does extensive in-formal outreach from its major laboratories inMaryland and Colorado. NIST encourages its re-search staff to give talks and demonstrations atschools, and work with acience fairs and infor-mal education programs.

USDA is surprisingly active in early scienceeducation. In pal ticular, the well-established 4-H program, which has over 5 million participantsin counties throughout the Nation, reaches an

enormous number of children. USDA is launch-ing an initiative to bring more basic science con-tent into 4-H programs, involving such modernareas relevant to aicultural research as biotech-nology and remote sensing. (See box 6-C.) Theyhave received a small amount of funding fromNSF to develop innovative science programswithin 4-H. USDA also has many informal out-reach and career programs. The Agricultural Re-search Service is the home for USDA's summerresearch apprentice program, which supportsabout 200 students each summer.

Within the Department of the Interior, the U.S.Geological Survey has extensive and well-orga-nized elementary and secondary education pro-grams. They also sponsor summer jobs for geol-ogy teachers. Other branches of the Departmentof the Interior have educational programs, mostlyinformal outreach. Much of the work of the In-terior lends itself to summer internships forstudents.

Box 6- C. --4-H: Five Million Children

There are nearly 5 million children involved in 4-H, most ct the age of 12.1 The goals of 4-H areto teach children about agriculture and related sciences, inc.. -hnological and science literacy, andto interest children in agriculture aryl science careen.' 4-H is mounting a sdence and technology initia-tive that will broaden its scope to include the modem technologiesand basic biological, physical, and chemicalsciences that feed into agriculture. The cote of 4-H is hands-on individual projects that allow ci"ldren tolearn by doing. Real-world applications include agriculture, food, nutrition, and soil science, from themorefamiliar growing gardens and raising goats to computer programming, space-based remote sensing, andmolecular genetics. 4-H participants complete several projects a year that teach principles of the scientificmethod. Other media include instructional TV, science andagriculture fairs, visits to colleges and universi-ties, and camps.

4-H draws upon a vast network of county extension agents, professionals, educators, and volunteers.This network is based in land-grant colleges and extension services. They support the over 600,000 volun-teer leader-teachers who assist children in their projects. Many programs are in-school, involving teachersand dubs (4-H provides informal teacher training). Others are out of school with family, employer, andcommunity support.

The national 4-H office is also sponsoring research into how children preparifor and choose agricul-ture aw l other science careers. This aims to promote positive attitudes toward science and technology, andhelps 4 H design programs i.oencourage children to enroll in mathematics and oder= courses in high school,and k.ter to enter science majors at universities (particularly, but not exclusively, aviculture-related majorsat land-grant universities).

Money comes from the Cooperative Extension Service, jointly funded by Federal, State, and countygovernments. Total public funding for 4-H is about $260 million. The Federal contribution is probablyr bout $70 to $100 million, although it is difficult to estimate because all Federal funds go into the generalCooperative Extention Service br get and cannot be distinguished by their end use. Industry and founda-tion contributions are on the order of $50 million. The estimated value of volunteer time is $1 billion.

RETHINKING THE FEDERAL ROLE INMATHEMATICS AND SCIENCE EDUCATION

In thinking of any p llicy problem, it is usefulto identify what goals a system is intended tomeet, what alternative actions need to be weighed,and how those actions can be implemented to ful-fill system goals. In the case of elementary andsecondary mathematics and science education, itis the last or these that is the most difficult. Whatneeds to be done is much more obvious than de-termining how it is to be done. The Federal Gov-ernment is historically at least one step removedfrom those who have the most direct influence onteaching and learning -- families, teachers, schools,and students. The Federal Government can anddoes provide incentives and support for some ac-tions rather than others; rethinking the mecha-nisms of Federal support affects the larger issueof the division of roles nationally in education.

Mathematics and science education are part ofa much larger set of issues with national dimen-sions; all, however, are built from the ground up.neighborhood schools, locally elected schoolboards, and State governments. The tension be-tween national and local priorities has a long his-tory, but is ultimately an ebsential part of theAmerican system of participatory democracy.Reconciling national and local visions should be

regarded as the job of educational p 'icymaking,not an obstacle in its way.

Today.. rsev phase of Federal interest in edu-cation is derelopirk,-,. Jt is based on the need totrain a 'oetter ,Iwii!) wo.-k forcf! as well as theneed to ensure equ,ty of educational provision toall young Americans. The heightened importanceof these needs will require change in several areas,including organizational arrangements in schoolsand school districts, the upgrading of the teacherwork force, and, ultimately, new spending. Thereal cost of elementary and secondary educationis already rising. More important, the need to im-prove mathematics and science course offerings,it zroduce more experimental work in classrooms,extend informal learning opportunities, and fuelenrichment programs both in and out of schoolcannot be met by improvements in the existingsystem alone. In particular, greater use will bemade of both individual and collective learningstyles in class and out.

The special challenge to formal mathematicsand science education is its ability to commandadequate, but not excessive, attention relative tothe vast number of other issues that arise inelementary and secondary education.

Various Years

National Assessment of Educational Prrgress(NAEP) (formerly administered by the EducationCommission of tilt. States and now by EducationalTesting Service, Inc. (ETS)). NAEP is a congression-ally mandated program, funded by the Office of Edu-cational Research and Improvement of the Departmentof Education, that assesses national achievement ineducation, including science and mathematics.' ETSnow refers to it as "The Nation's Report Card." Themost recent science and mathematics assessments werein 1985-86 (published in June 1988); previous assess-ments were in 1981-82, 1977-78, 1972-73, and, for sci-ence only, 1969-70. Each science test measured bothscience attitudes and achievement. The 1981-82 and1985-86 assessments addressed attitudes to science inmore detail than before and the 1985-86 assessment,for the first time, asked for background informationon science experiences out of school and on what isbeing taught in science classrooms. In 1985-86, teacherswere also asked to provide information on their train-ing and experience, instructional methcds, and theirintended curriculum. To conduct the assessment,NAEP identifies a stratified probability sample ofschools and tests students in three age groups: 9, 13,and 17. Anywhere between 60,000 and 90,000 studentstake NAEP tests, although any given test item is takenonly by 2,600 indiviauals. (ETS terms the tecl "ique"Balanced Incomplete Block Spiralling.") After assum-ing responsibility for NAEP, ETS introduced a degreeof cohort matching into its assessment design.' Co-

1977 and 1985

National Surveys of Science and Mathematics Edu-cation, sponsored by the National Science Foundationand conducted by Iris Weiss of Research Triangle In-stitute. The survey requested science and mathematicscourse offerings and enrollment (by race, ethnicity,and sex), science facilities and equipment, instructionaltecnniques used. and teacher training. All data wereself-reported. The 1985 survey covered 425 schools,public and private. including 6,000 teachers, and wasstratified by grades: K-3, 3-6, 7-9, and 10-12. The sur-vey was published in November 1987. The data do notaddress achievement.

Survey of High School Teachers and Course Offer-ings, conducted by the National Science TeachersAssociation (NSTA). The survey was based on an"Official J.S.! Registry of Teachers" maintained byNSTA, which is intended to list all science teachersof grades 7-12. All private and public secondary schoolprincipals were asked to name all their science teachersand the number of classes of each type of science thatthe teachers will teach during the coming school year.A stratified random sample of 2,211 high schools wasculled from 26,000 responses, derived in turn from atotal pool of 48.427 forms mailed. Stratification wasby seven ranges of school size, three grade structures(K-12, 7-12, and either 9-12 or 10-12), and by publicor private status. Data have been used by NSTA toestimate the number of sections of each type of sci-ence course taught, the number of high schools thatoffer either nc physics, chemistry, or biology courses,the number of teachers teaching "in-field" and "out-of-field,' and the teaching load of average physics, bi-ology, and chemistry teachers.

CrossSectional and Internationals1980-82

Second International Mathematics Study (SIMS)(U.S. Co-ordinator: College of Education, Universityof Illinois at Urbana-Champaign. Published as The Un-derachieving Curriculum, January 1987). Data werecollected in 1980-82 and covered 20 countries. TheU.S. survey covered 500 classrooms in 2 populations:grades eight and those completing secondary schooland taking a large number of mathematka r:ourses (de-fined as 12th graders taking college preparatory math-ematics). Both SIMS and the Second International Sci-ence Study (SISS) focused on three stages of theeducational process: the intended curriculum (what isin the textbooks), the implemented curriculum (whatthe teacher actually does in class and how), and theattained curriculum (what the students learned). Theintended curriculum is based on a content analysis oftextbooks, while the implemented cu iculum wasmeasured by asking teachers to complete question-naires. The attained curriculum was tested by multiple-choice achievement tests. SIMS attempted to study therelationship between what happens in schools andwhat students learn, so the achievement batteries wereadministered twice: once at the beginning and once atthe end of each school year.

Mathematics and Science Education inJapan, Great Britain, and the Soviet Union

During recent years, a steady stream of internationalcomparisons of elementary and secondary educationhas painted an increasingly bleak picture of the defi-ciencies of American mathematics and science educa-tion. Depressing comparisons with teaching practicesin Japan, Taiwan, Hong Kong, and South Korea havebeen seized on by many of those pressing for theUnited States to address its crumbling competitiveness.The source of competitive advantage is often referredto as "human resources" or "human capital"skilled,talented, and flexible workers. For example, a recentcommentary noted that international comparisons ofmathematics education " . . . typically depict Korean10-year-olds working out the Four-Color-Map Prob-lem in their heads while Americans of the same agestruggle to do double-digit multiplication withoutremoving their socks.'

Problems in Making InternationalComparisons

While international comparisons do point to signif-icant differences in mathematics and science courseofferings, curricula, and teaching, it is important tobear in mind two major problems in any sort of policy-oriented comparisons among cultures and countries:

developing a sufficiently accurate explanation ofthe causes of observed differences, which are veryoften rooted in what are, to the outsider, opar Lieultural and social differences in the roles of fam-

ilies, business, the State, law, and education; andhencedetermining what aspects of other systems couldreadily be appropriated and transferred acrosscultures and societies, and which would be fool-ish or even counterproductive to consider trans-ferring.

For example, the United ;aces cluld adopt a na-tional curriculum, but su_n a move would be resistedstrongly by many policymakers. Such a move wouldthreaten the fragile compacts between national and lo-cal autonomy stipulated in the Federal as well as Stateconstitutions. Further, a "national curriculum" wouldlikely consist of little more than a lowest common

denominator of topics defined by special interestgroups and argued out line by line in highly partisancongressional debates. Rather than providing modelsto be emulated, the ultimate: value of doing interna-tional comparisons may be to provide a kind of "mir-ror" in which to examine and better understand thereasons for well-entrc. ched, culturally rooted Amer-ican educational practices and policies.

On an analytical level, it is difficult to make soundinternational comparisons in education unless studiesare designed to compare "like with like" and to col-lect enough data to build a picture of overall educa-tional capacityteachers, students, and schoolsineach country. In considering the high school studentsexposure to mathematics and science, for example, itis important to note that the American school systemis designed to retain all students to age 18 ',and actu-ally succeeds in enrolling about three-quarters of thisgroup), whereas schools in other countries typicallyenroll a much more set 2ct group of students in the 14-to 18-year-old range.

These caveats aside, it is generally agreed that theAmerican education system devotes relatively less timeto mathematics and science education compared withother countries; estimates are that American studentsspend only one-third to one-half as much tip onleaning science as their peers in Japan, China, theU.S.S.R., the Federal Republic of Germany, and theGerman Democrat's Republic.' Significant differencesin the mathematical progress of children in selected cit-ies in the United States, Taiwan, and the People'sRepublic of China have been found from the elemen-tary grades. Japanese kindergarten children alreadysurpass American children in their understanding ofmathematical concepts.' It is evident that differencesare across the entire educational system of each nation.

Japan

The country with which commentators most enjoymaking international comparisons of mathematics andscience education is Japan.' Japanese children study

far more mathematics and science than American chil-dren, and more of them emerge from schools with agreater degree of scientific and technological literacythan do American children. Japanese institutions ofhigher education can draw from an exceptionally well-qualified crop of students. In addition, many go onto science and engineering majors; it is estimated that,in proportion to its population, Japan produces asmany scientists and twice as many engineers as doesthe United States.

Japanese education resides within the cultural milieuof Japan. A well-known recent study explored the im-portance of families in mathematics education. WhileJapanese families considered poor performance inmathematics to be a consequence of lack of effort,American families more often attributed success to in-nate ability, despite poor teaching.'

Japanese stvdents typically attend school for 240days per year (compared with 190 in the UnitedStates), because they work a half day on Saturdays.It is believed that they spend a greater proportion ofclass time on academic activities.'

In elementary schools, the science curriculum in-cludes matter and energy, living things and their envi-ronments, and the Earth and the universe. Thesethemes are often reinforced by educational televisionprograms broadcast by the Japan Broadcasting Asso-ciation and coordinated with the curriculum.' Stu-dents often go on field trips with their school. It iswidely reported that Japanese mathematics and sciencecurricula demand more from their students than thosein the United States: Japanese students simply covermore ground. Although Japanese and American ele-mentary school students spend a similar amount oftime on mathematics and science, from six to eightperiods per week, the time is far more intensively usedin Japanese schools.

Research data suggest that there is less variationamong students in mathematics and science learningthan in the United States. In part that is because Japa-nese elementary schools are not grouped or trackedby ability, and the use of mixed-ability cooperativelearning groups, or han, is very common. But it is alsodue .o the assumption that everyone can and must becompetent in these subjects. A recent book notes that:

It is simply taken for granted . . . that every child mustattain at the very minimum "functional mathematics,"that is, the ability to perform mathematical calcula-tions in order to accomplish requirements successfullyat home or work.°Japanese lower secondary schools, wnich cover

grades seven to nine, are similar to American juniorhigh schools, but have few or no electives. Studentsare required to wear uniforms and adopt a more seri-ous and disciplined approach to work than they hadin elementary schools. There is still no sorting by abil-ity, although the use of cooperative learning groupsis rare. Upon completion of lower secondary schools,at the end of ninth grade, all students have taken someelementary geometry, trigonometry, algebra, andprobability and statistics. They have devoted between6 to 8 out of 30 weekly class periods to mathematicsand science. In science, students take a variety of gen-eral science topics, including biology, chemistry,physics, and earth science. Teachers specialize in a sub-ject area and teach only that area. The pressure to getinto a good upper secondary school leads students inlower secondary schools to be highly competitive andneurotic, and the consequent pressure to succeed isoften cited as a cause of teenage suicide. Many stu-dents attend out-of-school juku, which are coachinglessons that prepare them for examinations for entryto upper secondary schools, mostly concentrating onEnglish and mathematics.

The final 3 years of school, upper secondary school,are quite different from the preceding 9. Entry to thislevel is on the basis of lower secondary school recordsand common entrance examinations administered bythe local prefecture; schools can be highly selective,and there is considerable variation in the courses thatstudents take. Attendance at upper secondary schoolsis voluntary, and tuition is charged. About 90 percentof young people attend them. Typically, several up-per secondary schools serve students within a givenneighborhood and there is a clear ranking of prestigeamong them. Some upper s 'ondary schools special-ize in academic-preparatory programs and other voca-tional programs; only about 30 percent offer both pro-grams.° While the post-war reforms at first embraced

140

the neighborhood comprehensive high school princi-ple, parents often lobbi.ed officials to send their chil-dren to the better neighborhood schools and upper sec-ondary schools now are definitely not equal.

Within Japanese upper secondary schools, studentsselect a given course of classes, and it is very difficultto change course or take classes outside those speci-fied for that course. There are few or no electives.Typically, academic-general and vocational-special-ized courses are offered, although both often havecommon coursework in the first year. Within the aca-demic-general course there is often a branch at the endof the fir f year of upper secondary school, at whichpoint those planning science and engineering majorsare separated from those planning arts majors. Stu-dents are often further sorted by ability levels withineach course. About two-thirds of the students takeacademic-general courses, one-quarter take vocationalcourses, and the remainder enter specialized collegesof technology or training schools, or enter the workforce directly.

Those planning science and engineering majors takea total of 102 credits over 3 years, of which 18 are inmathematics and 16 are in science; these credits includecalculus, physics, chemistry, and biology. In grade10,students spend 10 out of 34 hours per week in mathe-matics and science courses, rising to 14 and 18 hoursin grades 11 and 12, respectively. In grade 12, thescience-bound take 5 hours per week of integral anddifferential calculus as well as both physics and chemis-try. In total, one-half of those in academic high schoolsare in science courses. Nevertheless, the core coursesrequired for both the arts and the vocational-special-ized courses are sufficiently demanding in mathematicsand science that some students who have taken thesecourses can still compete for entry to college scienceand engineering programs. The uniformity of classesmeans that Japanese students have no equivalent ofthe advanced placement examinations, and must allstart with freshislan mathematics science programs atcollege. The upper secondary school curriculum is verydemanding, and some students fall behind and lose in-terest. The net effect is that, while the proportion of22-year-olds that receive baccalaureates in the UnitedStates and Japan is about the same (23 to 24 percent),about one-quarter of these in Japan are in natural sci-ence and engineering as compared to 15 percent in theUnited States.

Japanese public upper secondary schools are com-plemented by a number of private upper secondaryschools, in part because only a limited number of pub-lic schools were built after the war and the educationin lower grades was emphasized. About one-quarterof upper secondary schools are private. White some

of these schools are highly selective, others enroll thosewho failed to qualify for the limited number of placesin the public sector. Public schools generally carrymore prestige.

For the college-bound, the upper secondary yearsare extremely demanding as students prepare to takecollege entrance tests. In the Japanese system, thereis well-defined ranking of higher education institutionsand a student's decision to enroll in a particular insti-tution will have, through contacts with students andprofessors, a great effect on his or her later career, jobprospects, and life. The college education that studentsreceive is relatively unchallenging. The great compe-tition to enroll in the "right" university has createdpressure for a very intensive academic curriculum andthe extensive use of examinations to sort and preparestudents for college entrance in the upper secondaryschool years. Students often take both the nationallyadministered First Stage Standardized AchievementExamination and examinations set by the particularuniversity to which they are applying. These exami-nations test only factual recall and include no testingof skills with experiments and the process of construc-tion of new scientific knowledge. In preparing for theexaminations, students often enroll in yobiko whichare similar to the juku at lower secondary level.

In many ways, it is ironic that the Japanese schoolsystem does so well in mathematics and sciencewhereas the American system has problems, becauseJapan's schools were reorganized along American lines.The ultimate aim was to democratize and demilitarizeJapan during the post-war American occupation.Japan's schools have also made good use of curriculaand instructional material developed in A merica. Jap-anese schools are run by about 50 prefectural-levelschool boards and 500 local school boards which, un-like many of their American counterparts, are filledby people appointed from above rather than elected.The national Ministry of Education, Science, and Cul-ture (monbusho) prescribes curricula, approves text-books, provides guidance and funding, and regulatesprivate schools. The refectural boards of educationappoint a prefectural superintendent of education,operate those schools which are established by theprefectures (primarily upper secondary schools),license and appoint teachers, and provide guidance andfunding to municipalities. Municipal boards operatemunicipal schools, choose which textbooks to use fromthose approved by monbusho, and make recommen-dations about the appointment and dismissal ofteachers to the prefectural board.

The cost of education is shared by the various tiersof government and, at later stages, byparents directly.The Japanese government pays about half of the cost,

146

141

including some subsidies to private schools. Specialbudget equalizing regulations direct the central gov-ernment to augment the spending of poorer districtsup to a minimum level; there still remains a 60 per-cent variation in average per pupil expenditure amongschool districts. There is a uniform national pay scalefor teachers, with a modest starting salary and steadyannual increments that can triple a teacher's incomeafter 20 years of service. Overall salaries are competi-tive with other occupations, and teaching is an attrac-tive job; there are normally at least enough applicantsfor teaching positions, even in mathematics and sci-ences. Teaching remains one of the limited number ofprofessional occipations that are readily available towomen, but moat teach only in elementary schools;only 18 per-en± of teachers in upper secondary schoolsare female. Most teachers have degrees in single aca-demic disciplines other than education, although sub-stantial numbers have no degree at all. Each prefec-ture and large city has an education center for itsteachers, which provides inservice training and con-ducts educational research.

Curricula, in principle, we controlled by localschool boards, but the central Ministry of Educationsets standards in a "National Caurse of Study" andapproves textbooks. In practice, it is believed that thereis considerable uniformity of curricula. Curricula em-phasize mastery of key subjects, such as mathematicsand science, and make few concessions to individuallearning styles, predilections, and idiosyncracies. It isa belief in Japanese culture that creativity is only pos-sible once fundamentals are mastered.

Just as Americans admire the uniformity and ex-cellence of the Japanese system, many Japanese aresearching for ways to make their system less mono-lithic and competitive, and more respectful of individ-ual creativity, particularly as the country is now stress-ing the development of a basic research capability.'Japanese students are schooled to master factual ma-terial rather than analysis, investigation, or criticalthinking. Teacher lectures from textbooks are verycommon, although considerable use is also made oflaboratory work in science." Similar programs ofeducational reform analysis and activity exist in Japanand the United States; the United States program isoften taken as a model.' The Prime M;nister's Na-tional Council on Education Reform called in Septem-ber 1987 for the school system to put more emphasis

'The Japanese parallel to the U S Study of Education report is JapaneseStudy Group, Japan-United States Cooperative Study on Education, "Educa-tional Reforms in Japan," mimeo, January 1987, which studied aspects of U Seducational reform that might translate to Japan, especially the transitionbetween secondary and higher education

on diversity and creativity, but the council has beensplit by internal controversy over the shape of possi-ble reforms. It is believed that these calls may leadsome prefectures to combine lower and upper second-ary schools and to put a reduced emphasis on exar ina-tion-based sorting."

Great Britain

Most observers of Great Britain's system of mathe-matics and science education have concluded that itis very good for those who plan college study in sci-ence and engineering, but comparatively weak for therest." Students, by international standards, specializeat a very early age, and are offered few opportunitiesto shift interests. Preparation for examinations, whichare externally set and assessed, is the dominant activ-ity for those college-bound. Enrollment in higher edu-cation institutions is restricted both by financial mech-anisms and fairly strict entry requirements, and theproportion of British 18- to 22-year-olds that enrollin college may be the smallest in any developed nation.

Like the United States, comparatively little scienceis taught in British elementary schools and there arefew teachers qualified or motivated in the subjects. Theemphasis instead is on mathematics. Most studentsbegin science classes in one or more of the fields ofphysics, chemistry, and biology in the sixth grade,and continue them to the end of eighth grade. Ingrades 9 and 10, students choose a limited menu ofcourses to specialize in for the purposes of taking na-tionally administered school-leaving examinations(now known as the General Certificate of SecondaryEducation) at the end of 10th grade. Those college-bound in science and engineering might take six toeight subject exams, of which three or four are in math-ematics and science subjects. Enrollment in grades 11and 12 is voluntary, and is normally restricted to thosepreparing for nationally administered college . -anteexaminations (known as Advanced-level, or Alevel)examination.; A. this stage, students normally special-ize in only two or three subjects, which tend to be re-lated to each other, although proposals have oftenbeen made to expand this m. mber in the interests ofgiving college students a "broader education." In thesegrades, the science- and engineer:ng-bound can takeonly mathematics and science subjects, if they choose.

Entry to colleges and universities in Great Britainis granted on the basis of grades and the number ofpasses awarded in the A-level examinations, and most

142

institutions make offers to students conditional upontheir achievement of certain grades. A minimum oftwo passes in two subjects at A-level is normally re-quired, and entitles the student to free tuition and ac-cess to a grant program for living expenses while atthe university.

The Soviet Union

In many ways, the mathematics and science educa-tion system in the Soviet Union is similar to the Amer-ican and British systems." Each is a very uneven sys-tem, geared primarily to training those who willbecome professional scientists and engineers. The bulkof the school population learns relatively little and isleft largely alienated from science and engineering. Theextremes in the Soviet Union, however, are quite dis-tinct. The layer of top quality students, which ranksinternationally with the best, is very thin; there is asteep drop-off below that level.

The education system in the Soviet Union, like thatin the United States, Great Britain, and Japan, is un-dergoing reforms. The impetus for these reforms is thenew national desire to improve the efficiency of in-dustry.

Soviet elementary and secondary education is splitinto three phases:

primary or elementary education, grades 1-3"incomplete" secondary education, grades 4-8;and"complete" secondary education, grades 9 and 10.

Most students complete eighth grade, normallyachieved at age 15, and then choose among severaldifferent paths. Some continue in general educationsecondary schools and are most likely to enter highereducation, while others enter the work force but con-tinue their secondary education via evening or cor-respondent: ourses. Higher education is open to stu-dents from each of these routes, but most collegestudents come from those who enrolled full time ingeneral education secondary schools. A third path af-ter eighth grade is to enroll in a technical or vocationalschool. These schools are primarily intended to trainfuture skilled workers and technicians. For the mosttalented students, there are a number of specializedschools, often residential, some of which specialize inmathematics and science.

Entry to higher education in th Soviet Union iscompetitive, with an approximate oversupply of sec-ondary school graduates of between two and threetimes the number of higher education places available.

"The following is based on Harley Balzer, "Soviet Science and Engineer-ing Education and Work Force Policies Recent Trends," OTA contractor re-port, September 198i

Admission to higher education institutions is primar-ily by means of examinations. Political considerationsare often important, and students who participate inextracurricular social service activity, such as agricul-tural work, are often given some preference in admis-sions and award of stipends. Although only about 20percent of students go on to higher education, abouthalf of these are in science and engineering, with theeffect that a larger proportion of each birth cohortgraduates in sciences and engineering than in theUnited States.

Reforms in progress include a requirement for stu-dents to begin full-time education a year earlier, at age6 rather than age 7. The extra year will alkw time forstudy of additional ..ubjects such as labor educationand computer science. At the moment, computers arevery rarely used in classrooms, but their use has be-come a national priority. All students will have re-quired courses in information science, but it is likelythat many of these classes will be taught without hard-ware. To improve the skills of the work force, all stu-dents in general secondary education learn manual la-bor skills, even those who go on to higher education.The current phase of curriculum reform is designed tointroduce less demanding, but more comprehensive,curricula in many subjects, including mathematics andscience. This last step is ironic, because the intensityof the traditional mathematics and science curriculumis often praised by American commentators. Moremoney is being allocated to education; teachers' sala-ries are being increased and merit pay arrangementsare being introduced.

Under the ref---ms, closer links are being forged withboth higher education institutions and local firms andenterprises. All schools are being paired with neigh-borhood factories and businesses: enterprises will berequired to provide financial and material at.;istanceto schools and hope to receive better trained work-ers. Many higher education institutions are signingagreements with secondary schools, under which col-lege faculty will assist in secondary school teaching.Students will be given access to research facilities atcolleges, and the colleges will admit a specified num-ber of students to higher education. Research labora-tories are also being encouraged to participate in suchagreements. So far, 30 of about 900 higher educationinstitutions have signed agreements of this kind. Whilereforms of tills kind should improve the quality of edu-cation of future scientists and engineers, they will forcestudents to specialize at a younger age, often 15 or 16,than has been the case.

As a further part of the Soviet reform program,more students will be encouraged to enter technicallyoriented vocational programs in grades 9 and 10 rather

1'8

143

than general education secondary programs. Althoughthe training these students receive is supposed to beequivalent to that in general education secondary pro-grams, this step will probably reduce the already over-subscribed pool of qualified high school graduatesplanning to enter higher education. College entrystandards have also been tightened during the last 8years, except in fields such as computer science, andbiology, which have been targeted for expansion.

Conclusions

While mathematics and science education in othercountries contains many features to be admired, in-cluding the commitment to these subjects, the emphasison academic learning, and the geographical equaliza-

1 4 9

tion of learning epportunitics, each system containssome features that disturb many American educators.They include unswerving allegiance to the mastery offacts rather than creativity and individual expressionand the extensive use of lectures. Other unappealingfeatures are the limited number of women teaching inupper secondary schools, the central control over-many aspects of teaching, and the teaching of scienceand technology literacy to a select few rather than thefull cohort of students. Above all, many other coun-tries have a greater degree of centralization in educa-tional decisionmaking than exists in the United States.Schools and school districts need to identify practicesthat are transferable, but also need to be extremelycautious of the cultural and social assumptions under-lying some of these practices.

OTA Survey of the National Associationfor Research in Science Teaching

The National Association for Ret.zarch in ScienceTeaching (NARST) is an organization of university re-searchers in mathematics and science education. InJune 1987, OTA mailed questionnaires to the Amer-ican membership of NARST, asking for their opinionson a range of current and past Federal programs de-signed to improve precollege mathematics and scienceeducation. Of 500 questionnaires mailed out in this in-formal, one-shot survey, 135 were returned for a re-sponse rate of just over 30 percent.

The survey was designed to give OTAa general im-pression of th- opinions held by individuals knowl-edgeable about previous Federal efforts in this area.NARST includes many active participants and evalu-ators of previous Federal mathematics and science edu-cation programs; their responses provided valuable,often first-hand, accounts of programs such as Na-tional Scier e Foundation (NSF) summer institutes andcurriculum development programs. Respondents alsohad extensive familiarity with c- her local, State, andNSF-sponsored programs that are listed below. OTArecognizes that the members of NARST are neitherrepresentative of the broad population of researchersand teacher educators in mathematics and science edu-cation, nor are the responses statistically representa-tive of the entire NARST membership.

OTA solicited opinions on the effectiveness of thefollowing programs:

grants for equipment and supplies under the Na-tional Defense Education Act (NDEA) of 1958;NSF summer institutes and other inservice train-ing for teachers;NSF summer institutes for students and other re-search participation programs for students;NSF-funded new curriculum programs;assistance for magnet schools for racial desegre-gation purposes;funds allocated through Title II of the Educationfor Economic Security Act of 1984; andsupport for informal science education, includingeducational television and science and technologycenters.

Of these programs, NSF teacher institutes, researchparticipation for students, and curriculum develop-ment programs received the highest ratings. Many re-spondents thought that significant lessons had beenlearned from the teacher institutes and curriculum de-

144

velopment programs, such as the need to ensure thatparticipating teachers are given followup training andthat training covers both subject knowledge and ideasfor teaching mathematics and science in real-life situ-ations. Magnet school programs were the least highlyrated, although less than one-half of the respondentscited these programs at all.

OTA also asked respondents to identify other Fed-eral programs that they thought had had a positiveeffect on mathematics and science education. Thesenominations provide a fairly comprehensive overviewof the kinds of Federal programs that have been at-tempted since passage of the NDEA:

NSF-funded Institutes for Science and Mathe-matics Supervisors;funds for Research on Teaching and Learning ofScience and Mathematics;NSF-funded Chautauqua Institutes for Teachers;the Department of Education's National DiffusionNetwork for the dissemination of effective cur-ricula materials;Programs for Metric Education;the Department of Education's Fund for the Im-provement of Post-Secondary Education;'Presidential Awards for Teaching Excellence inMathematics and Science;the National Assessment of Educational Progress,funded by the Department of Education;NSF's Project SERAPHIM;the National Aeronautics and Space Administra-tion's program for sending astronauts and scien-tists to schools and a similar program funded byNSF;the Clearinghouse for Research in Science, Math-ematics, and Environmental Education that is partof the ERIC system;National Sea Grant College Marine EducationActivities;'he Department of Energy's Honors Science Pro-gram; andNSF's program of Resource Centers for Scienceand Engineering.

'Despite its name, this source has funded some precollege programs, suchas the Family Math series of books and materials from the EQUAL.; pro-gram at the Lawrence Hall of Science, University of California at Berkeley.

Several respondents made noteworthy observationsregarding:

the importance of educating guidance counselors,principals, and school board members about theproblems of science education, particularly toconvey that science i3 a collection of facts as wellas a way of exploring and examining the world,and that the interest of many students in scienceneeds to be developed;the diminutive size of Federal mathematics andscience education programs in relation to the sizeof the problems;the fact that past programs have not done a goodjob at distinguishing between programs for train-ing future scientists and engineers and programsfor boosting technological literacy. NSF programshave often been aimed at the former, and havemade too great a use of working scientists whohave limited appreciation of the culture of schoolsand the need to involve parents, school boards,

151

and administrators if improvement is to be last-ing and meaningful;the need for ongoing training and support for pro-grams, once mounted. In many cases, programshave attempted too much too quickly, and havefailed to follow through, allowing the status quoto be reasserted;the increased use of science specialists and con-sultants to be shared among schools or evenschool districts;the need for more emphasis on elementary math-ematics and science education, where the battleis won or lost, rather than on secondary educa-tion what too many deficiencies are already ir-re vocabie; andthe recognition that good teachers are an abso-lute precondition to improvements in other areas,such as curriculum, equipment, and testing. Sci-ence and mathematics teacher education programsat universities need to be updated and fortified.
