so the teachers could attend and maintain contact through- out the year.

The following summer, 1987, the high school teacher staff- ing was thesame as the previous year with the exception that both participated for a full 10 weeks. The teachers were experienced in the lah procedures and theory, having kept familiar with them through the weekly academic year re- search meetings. In the following description, we will discuss primarily the summer 1987 program.

Organization and Function Our research m o w in summer 1987 consisted of 13 indi- - .

viduals including the two high school teachers,a recent grad- uate, four undergraduates. n high school graduate, four high school students, and the principal investigator. Such a large group requires thoughtful organization. Since the two high school teachers were fairlv familiar with the lahoratorv ooer- ations, each of them tookaalf of our participants under their supervision. With support from the two most senior college students the plan was for them to supervise and participate in the projects of one of our grants, a National Institutes of Health Academic Research Enhancement Award (NIH AREA), or the other, an American Chemical Society Petro- leum Research Fund grant (ACS-PRF). The organizational plan is illustrated in Figure 1, wherein "Research Associa- tes" refers to the high school teachers, "Hackman Fellows" are the college students supported with stipends from the Hackman Summer Research Fund a t Franklin and Marshall College, and "Research Assistants" are the high school stu- dents.

The daily routine during the summer began with a meet- ine of all ~ a r t i c i ~ a n t s a t 8 a.m. a t which each oarticinant reciewed <he past day's work and planned the current iay's work. We have found it helpful when workine with freshman and sophomore undergraduates and with k g h school stu- dents to plan their work carefullv each dav. In addition to the review and planning, one of the more experienced mem- bers of the group gave a 30-min presentation on some area of theory related to the work of our laboratory. The theory was presented in such a way that the topics needed for experi- mental work (such as X-ray crystallography) came early in the summer, so, once the synthesis and crystal growing was completed, the students were ready for the more complex processes.

The organizational chart in Figure 1 shows that E. K. John and G. W. Shaffer each had one very experienced student under them (S. Bell and B. Wolfe). The less experienced

college students and most high school students in turn worked with Bell and Wolfe. S. Clymer and A. Musselman were two high school students collaborating on a major com- puter-programming project related to our specnlar reflec- tance microspectrophotometer, and worked directly under G. W. Shaffer, who was the overseer of the reflectance in- strument. The principal investigator (PI) was able to con- centrate his efforts on leadine the dailv nlannine sessions. " . . "

writing papers and proposals, and answering the questions that the other most ex~erienced members of the eroun could - not answer. To encourage independent thinking, only select- ed times were provided for his answering questions: during the morning meeting, just before and after lunch, and at the end of the day. This also ensured uninterrupted blocks of time for the PI'S study and writing.

As the summer progressed, the organization evolved to- ward a more procedure-oriented division of support on the part of the experienced members of the group. The evolved group organization is depicted as a Venn diagram in Figure 2. Generally, one or two individuals were the resident ex- nerts on each techniaue such as transition metal comolex synthesis, X-ray ~r~s~a l lography , ORTEP drawings, reflec- tion spectroscopy, etc. The original supervisors remained as project supervisors but natural collaborations developed among the group members.

Achievements The specific projects ranged from preparation of single

crystals of Ni(CN)42- salts to difficult organometallic syn- theses and from performing Gaussian curve deconvolution to frontier theoretical considerations of the effect of reflec- tions on Kramers-Kronie transformations (5) of s~ecular reflectance into absorhake spectra. Most projects were typical of undergraduate research projects, but three were especially noteworthy because of their heavy involvement of high school teachers and students.

One was the job of preparing single crystals of several Ni(CNh- salts, which required some synthesis in addition to recrystallization. This was performed by a pair of high school students working primarily under a high school teacher. This was a sucEeisful project because the proce- dures were well within the capability of thestudents. Result- ine crvstals have since been used for a local science fair pGjeci by a third high school student. Using X-ray diffrac- tion and o ~ t i c a l methods. the crvstals were found to be well developed-and single.

A second was the writing of three computer programs for three Apple I1 computers connected to e&h other &d to an HP3000 mainframe that would serve as a simulator for our specular reflectance instrument. Two high school students

supervised by a high school teacher carried out this project successfully. Numerous interfacing problems were encoun- tered, including the need to make an Apple I1 behave in a nonstandard manner in order to simulate accurately the monochromator controller in the reflection instrument.

The third project of special note was the preparation of two cobalt dimer complexes and an iron dimer complex by a high school teacher and two undergraduates over the past twosummers. These comnlexes serve as models for the binu- clear copper protein hemocyanin and iron protein hemery- thrin. The team was vew effective in searchine the auurouri- ate literature (&8), inciuding original ~ e r n e r p a p e r s i n der- man, devising procedures and preparing the compounds

The middle com~lex salt is a new material. X-ray structures are currently hekg performed on the cobalt co&pleaes at a collahoratinr! laboratory, and the iron complex is being char- acterized m~rphologicdly and spectroscopically.

Academic Alliances in Chemistry Academic alliances, where faculty from both high schools

and colleges in a particular discipline collaborate on course development, research, and general professional concerns, have existed for manv vears in foreim laneuwes and litera- ture, history, and more recently in Englis<, t i e humanities, and sciences. Academic Alliances in Chemistry is a new pro- gram established and funded by The Camille and Henry Dreyfus Foundation and administered by The Woodrow Wilson National Fellowship Foundation, and coordinated by Amie Knox. The goal is to promote interaction between high school and college teachers in a variety of activities, including formal meetings a t which topics of academic inter- est are discussed, casual contacts or visits to classrooms, and summer and academic year research collaboration.

Formation We learned of the Academic Alliances in Chemistw uro-

gram after the first summer of our collaboration at ~ r&kl in and Marshall College and realized we had already been car- rying out one of the functions of an academic ailiance. We also learned that a Dreyfus Master Teacher is needed to initiate a local academic alliance for recognition by Academ- ic Alliances in Chemisrry. Since one of us (EKJJ has been a Dreyfus Master ~ e a c h e ~ for several years, she was the natu- ral choice to take the lead. Her first step was to gather additional chemistrv facultv and a develonment officer a t Franklin and ~ a r i h a l l college as a steering committee which olanned an oreanizational meetine of local college and high sihool teachersfor December 198g. ~nformation from 15 institutions was eathered and an application for recoeni- tion was sent to ~ c a h e m i c Alliances inchemistry.

Initially, four local colleges and 12 high schools joined the group known as the Dutch Country Academic Alliance in Chemistry (DCAAC). Three meetings were held in winter and spring 1986, during which time a matching grant was received from Academic Alliances in Chemistry for the pur- pose of supporting several high school teachers for summer research a t the cooperating colleges.

The DCAAC has now been in existence for about a year and a half and has grown to include five area colleges and universities, a major international industry, headquartered locally, and over 13 high schools. The original steering com- mittee coordinated by E. K. John has matured into a set of officers with an executive committee to handle meeting agenda, funding proposals, finances, and a newsletter. Dur- ing summer 1987 four colleges sponsored research participa- tion with seven high schod teachers. For summer 1988 five ~ - - - ~ ~~-~ ~ ~ ~ " ~~

colleges and an industry will sponsor about 10 high school chemistry teachers in research collaborations.

The goal of the DCAAC has been to improve chemical education throueh close ties between hieh school and college faculty. Our specific methods have been the fostering of relationshius which enable members to call on one another for assistance in theory or presentations, to present informa- tion on the orofession such as safetv procedures and new curricula, and as emphasbed in this paper, the provision of research opuortunities for high school faculty in our colleges and industry.

.

A Reluctance Factor We have noticed an unexpected problem with some of our

efforts a t research collaboration: onlv a verv small uercent- age of high school teachers apply fo;summ& research pro- erams.This was trueat Princioiaand is thecasein theDutch - Country Alliance. Several possible reasons have been sug- eested: (1) 8-10 weeks is too much of the summer to devote to a sin& endeavor, (2) more supplemental income can be found elsewhere, and (3) many teachers are reluctant to place themselves in a position wherein their knowledge of chemistry is observed by peers. The first problem can be remedied by offering five-week research collaborations where that is practical. The second can be overcome by offering more competitive stipends. Recent values have var- ied from $1250 to $2700 for a 10-week period. The latter value becomes somewhat comuetitive. The third uroblem is a very sensitive one and mustbe approached carefully. The emuhasis must be on mutual collaboration wherein each individual is recognized as bringing some unique contribu- tion to a research oraanization. In addition, it should be stressed that no one iGdividual can he expected to be famil- iar in detail with all areas of chemistry, and being unfamiliar with many areas is, in fact, professionally acceptable. With this preamble a teacher may be more willing to collaborate with colleagues. In addition, i t must be recognized and em- phasized that the summer experience is a time for the high school teacher to rejuvenate enthusiasm through learning and discovering new ideas.

Summary Hieh school teachers are a valuahle addition to chemistrv

research laboratories and can produce impressive results either on their own or in collaboration with undergraduates or high school students. Their professional training and teaching experience allow for creative productivity in a con- centratGd s"mmer research experience. ~ a m i l i a r i t ~ with a program during an academic year can enhance the research results. The principal beneficiaries in addition to the teach- ers are the college and high school students working with the teachers during the summer and the teachers' students dur- ing the following academic year. The latter is due to an enhanced enthusiasm and a greater sense of authority in the classroom.
