UNDERSTANDING OF NEWTON’S LAWS OF MOTION

ABSTRACT

Supervising Professor: Mary Urquhart

Misconceptions of Newtonian mechanics and other physical science concepts are well

documented in primary and pre-service teacher populations (Burgoon, Heddle, & Duran, 2009;

Allen & Coole, 2012; Kruger, Summers, & Palacio, 1990; Ginns & Watters, 1995; Trumper,

1999; Asikainen & Hirovonen, 2014). These misconceptions match the misconceptions held by

students, leaving teachers ill-equipped to rectify these concepts in the classroom (Kind, 2014;

Kruger et al., 1990; Cochran & Jones, 1998). Little research has been devoted to misconceptions

held by in-service secondary teachers, the population responsible for teaching Newtonian

mechanics. This study focuses on Texas in-service science teachers in middle school and high

school science, specifically sixth grade science, seventh grade science, eighth grade science,

integrated physics and chemistry, and physics teachers.

This study utilizes two instruments to gauge conceptual understanding of Newton’s laws of

motion: the Force Concept Inventory [FCI] (Hestenes, Wells, & Swackhamer, 1992) and a

custom instrument developed for the Texas Regional Collaboratives for Excellence in Science

and Mathematics Teaching (Urquhart, M., e-mail, April 4, 2017). Use of each instrument had its

vii

strengths and limitations. In the initial work of this study, the FCI was given to middle and high

school teacher volunteers in two urban school districts in the Dallas- Fort Worth area to assess

current conceptual understanding of Newtonian mechanics. Along with the FCI, each participant

was asked to complete a demographic survey. Demographic data collected included participant’s

sex, years of service in teaching position, current teaching position, degrees, certification type,

and current certifications for science education. Correlations between variables and overall

average on the FCI were determined by t-tests and ANOVA tests with a post-hoc Holm-

Bonferroni correction test. Test questions pertaining to each of Newton’s three laws of motion

were extrapolated to determine any correlations. The sample size for this study was small (n=24),

requiring a second study investigate potential correlations to teacher characteristics.

The second study was conducted using the 2013-2014 school year participants in the Texas

Regional Collaboratives for Excellence in Science and Mathematics Teaching [TRC] (Texas

Regional Collaborative for Excellence in Science and Mathematics Teaching, 2013), a statewide

program led by The University of Texas at Austin Center for STEM Education (Texas Regional

Collaborative for Excellence in Science and Mathematics Teaching, 2013). Participants

completed a demographic survey and took the TRC Physics Assessment instrument developed

for the TRC to determine current conceptual understanding of Newtonian mechanics as defined

by the Texas Essential Knowledge and Skills. The TRC also collected demographic data

including Texas Educational Agency region, participant’s sex, years of service in teaching,

current teaching position, level of highest degree earned, whether or not the participant had a

STEM degree, and certification type. Correlations were determined between overall average and

conceptual force questions only. The sample size was substantial (n=368) but due to time

viii

constraints in its development, the TRC Physics Assessment was unable to undergo reliability or

validity testing before implementation. Test question pertaining to each of Newton’s three laws

of motion were extrapolated to determine any correlations. A significance value of p= 0.05 was

used for all tests.

Both content assessments indicated that, on average, teacher-participants had a considerable

misunderstanding of Newtonian mechanics with Newton’s third law questions especially

difficult for the populations. Teachers’ current teaching assignment was statistically significant

for most tests, suggesting that high school physics teachers have more conceptual understanding

of Newtonian mechanics than middle school teachers but have not necessarily mastered

Newtonian mechanics. STEM majors and participant’s sex were significant only for the TRC

Physics Assessment.

One outcome of this study is a recommendation that the Texas teacher certification process for

middle school science change to include a general science test that includes physical science.

Also, in-service science teachers responsible for teaching Newton’s laws of motion should

participate in specific professional development from a physics content educational expert to

address misconceptions. Additional recommendations include that physics teachers take a

mentoring role to help other teachers in physical science concepts and that middle school

curriculum provide assistance to teachers for addressing misconceptions of Newton’s third law.

CHAPTER 1

INTRODUCTION

Teacher knowledge directly influences student knowledge (Sadler, Sonnert, Coyle, Cook-

Smith, & Miller, 2013; Abell, 2007). Teacher knowledge is defined as both content knowledge,

referred to as CK in this study, and pedagogical content knowledge, referred to as PCK (Abell,

2007). The influence of CK versus PCK is mixed with some research showing teacher degrees in

formal education an influencing factor (Hill, Rowan, & Ball, 2005; Hashweh, 1987) and other

studies finding teacher experience more influential (Sanders, Borko, & Lockard, 1993; Deng,

2007). However, the research indicates that the most effective teachers are those who have both

strong CK and PCK (Abell, 2007; Etkina, 2010; Sadler et al., 2013).

Current research in physical science content knowledge has focused mainly on in-service

elementary science teachers (Burgoon, Heddle, & Duran, 2009; Allen & Coole, 2012; Kruger,

Summers, & Palacio, 1990; Ginns & Watters, 1995) and pre-service physics teachers (Trumper,

1999; Asikainen & Hirovonen, 2014). There are limited studies on physical science content

knowledge in secondary science in the United States (Sadler et al., 2013).

Middle school science teachers are responsible for teaching basic physical science

concepts including Newton’s three laws of motion (Next Generation Science Standards, 2013;

Texas Essential Knowledge and Skill [TEKS], 2010). Sadler’s et al. (2013) national US study

tested 181 current in-service middle school physical science teachers’ content knowledge using a

multiple choice pretest and posttest covering the grades five to eight physical science standards

of the National Science Education Standards [NSES]. Initially, they found teacher subject

2

knowledge of the physical science standards of the NSES was strong, but there were “noticeable

holes in their knowledge (p. 1043).” Yip, Chung, & Mak (1998) studied a similar population of

147 in-service middle school science teachers in Hong Kong using a true false physical science

competency test and found the teacher population’s content knowledge of physical science was

weak. Yip et al. emphasized that those teachers who majored in physics had stronger physical

science knowledge than teachers who did not major in physics, but they did not possess enough

physical science knowledge for mastery. Harrell (2010) studied 93 in-service eighth grade

science teachers described as highly qualified for the content by Texas certification. Using

undergraduate transcripts and the 8-12 science Texas Examination of Educator Standards

[TExES] diagnostic examination, she found physical science content knowledge for the

population as overall insufficient.

The American Association of Physics Teachers [AAPT] (1988) described the ideal

physics teacher as a teacher who majored in physics. However, Trumper’s (1999) study on 25

pre-service physics teachers in Israel using a multiple choice test determined the teachers still

had misconceptions about force and motion after completing a four year study in physical

science education. Asikainen and Hirvonen (2014) studied nine pre-service physics teachers and

18 in-service physics teachers in Israel. Using interviews and an open-ended test, they

ascertained that the population also had physical science misconceptions although this study

focused on quantum mechanics. Galil and Lehavi’s (2006) study tasked 75 in-service physics

teachers to define physics concepts. They determined that the resulting definitions were

insufficient, which alludes to conceptual misconceptions but is not definitive.

3

Little research in the United States has focused on secondary in-service teachers’ physical

science content knowledge and what characteristics correspond with misconceptions (Sadler et

al., 2013). Arzi and White (2007) found that formal education was forgotten and specific content

knowledge was retained as a teacher continued teaching through years of service. Similarly,

Sander et al. (1993) found that when teachers were forced to teach content outside their

knowledge base, expert teachers would overcome knowledge deficits without intervention but

the process would take time. Kind’s (2013) study of chemistry teachers found misconceptions

are more prevalent in teachers responsible for science subjects not related to their degrees.

However, teachers who majored in physics still have physical science misconceptions (Galili &

Lehavi, 2006). It is unclear how prevalent physical science misconceptions are in the current

teaching population.

This study focuses on Texas in-service secondary science teachers who are responsible

for teaching physical science content, specifically Newton’s three laws of motion. This study

identifies current population’s conceptual understanding of Newton’s three laws of motion and

identifies any correlations between teacher physical science content knowledge and teacher’s

characteristics, including educational background, certification, and years of service.

Statement of Problem

As previously noted, research has shown that teacher content knowledge affects student

knowledge. Current research cannot adequately describe how prevalent misconceptions about

Newton’s three laws of motion are within the physical science teacher population. Conflicting

research cannot clarify if teacher background, formal science education, or years of service

4

correlate with proper understanding of Newtonian mechanics (Kind, 2013; Sadler et al., 2013;

Galili & Lehavi, 2006; Trumper, 1999).

Purpose of Study

The purpose of this study is to identify current Texas sixth grade science teachers,

seventh grade science teachers, eighth grade science teachers, integrated physics and chemistry

teachers, and physics teachers’ conceptual understanding of Newton’s laws of motion and to

identify any correlations between teacher characteristics such as formal science education at the

undergraduate level, certification, and years of service with conceptual understanding of

Newtonian mechanics. According to the Texas science standards, the TEKS, these teachers

directly teach Newtonian mechanics to their students, so teacher misconceptions could pose an

issue for student learning (Sadler et al., 2013; Burgoon et al., 2009; Berg & Brouwer, 1991) (see

Appendix A for a full list of TEKS).

Research Questions

For the purpose of this study, the following questions were addressed (see Figure 1.1):

1. What is the overall conceptual understanding of Newtonian mechanics in the current

Texas sixth grade science teacher, seventh grade science teacher, eighth grade science

teacher, integrated physics and chemistry teacher, and physics teacher population?

2. What is the conceptual understanding of each of Newton’s three laws of motion in the

current Texas sixth grade science teacher, seventh grade science teacher, eighth grade

5

science teacher, integrated physics and chemistry teachers, and physics teacher

population?

3. Is there a correlation between the sex of the teacher and his or her conceptual

understanding of Newtonian mechanics in the current Texas sixth grade science teacher,

seventh grade science teacher, eighth grade science teacher, integrated physics and

chemistry teacher, and physics teacher population?

4. Is there a correlation between school district or region and conceptual understanding of

Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

5. Is there a correlation between grade level taught and conceptual understanding of

Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

6. Is there a correlation between years of service and conceptual understanding of

Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

7. Is there a correlation between highest earned degree and conceptual understanding of

Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

6

8. Is there a correlation between undergraduate major and conceptual understanding of

Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

9. Is there a correlation between type of certification program and conceptual understanding

of Newtonian mechanics in the current Texas sixth grade science teacher, seventh grade

science teacher, eighth grade science teacher, integrated physics and chemistry teacher,

and physics teacher population?

10. Is there a correlation between the teacher subject certification and conceptual

understanding of Newtonian mechanics in the current Texas sixth grade science teacher,

seventh grade science teacher, eighth grade science teacher, integrated physics and

chemistry teacher, and physics teacher population?

Hypotheses

This investigation included the following hypotheses (see Figure 1.2):

1. Teacher misconceptions about Newtonian mechanics are significantly prevalent in the

Texas sixth grade science teacher, seventh grade science teacher, eighth grade science

teacher, integrated physics and chemistry teacher, and physics teacher population.

2. No correlation exists between sex of the teacher, school district, undergraduate major,

certification program, or type of teacher subject certification with conceptual

understanding of Newtonian mechanics in the Texas sixth grade science teacher, seventh

grade science teacher, eighth grade science teacher, integrated physics and chemistry

teacher, and physics teacher population.

3. A positive correlation exists between undergraduate major in STEM and conceptual

understanding of Newtonian mechanics in the Texas sixth grade science teacher, seventh

grade science teacher, eighth grade science teacher, integrated physics and chemistry

teacher, and physics teacher population.

Newtonian mechanics in the Texas sixth grade science teacher, seventh grade science

Newtonian mechanics in the Texas sixth grade science teacher, seventh grade science

teacher, eighth grade science teacher, integrated physics and chemistry teacher, and

physics teacher population.

Definition of Terms

1. Significantly Prevalent- the target population exhibits >40 percent of Newtonian

misconceptions as defined by Hestenes and Halloun’s (1995) response to exploring the

Force Concept Inventory.

2. Grade level taught- the target’s current teaching position will only be considered. In the

case of split level teaching, target’s majority >50 percent of teaching time, will be

considered current teaching position as defined by the Texas Education Agency (2015).

3. Certification Program- the target’s type of program in which a teaching certificate was

earned, either defined as traditional certification program or alternative certification

program as determined by Texas Education Agency (2015).

4. School District- the target’s current school district at time of participation.

5. Undergraduate Degree- an undergraduate degree will be defined as a Bachelor of

Science, a Bachelor of Art, Bachelor of Fine Arts, and Bachelor of Business

Administration.

6. Years of Service- years of service will count upon the continuation of one academic year.

Targets who are in their first year of teaching will have earned 1 years of service.

Semester only years will not count.

7. Science Teacher Certificate- science teacher certificates are divided into three categories;

Generalist, Science Generalist, Specialized Science. Targets will choose all certifications,

but targets will be categorized by most specialized degree.

10

8. Generalist- a target whose certification is of the following; Generalist EC-6, Generalist 4-

8, Core Subject EC-6, and Core Subjects 4-8 or of similar type. (See Appendix B for full

description.)

9. Science Generalist- a target whose certification is of the following; Science 4-8; Science

7-12; Mathematics Science 4-8; or of a similar type. (See Appendix B for full

description)

10. Specialized Science- a target whose certification is of the following; Chemistry 7-12; Life

Science 7-12; Physical Science 6-12; Mathematics/Physical Science/Engineering 6-12;

Mathematics/Physical Science/Engineering 8-12; Physics/Mathematics 7-12, Physics/

Mathematics 8-12. (See Appendix B for full description)

11. Knowledge Threshold- the amount of knowledge a target has about conceptual physics

determined by the Force Concept Inventory (Hestenes & Halloun, 1995).

12. Content Knowledge- content knowledge is understanding of physical science principles

and theories

13. Pedagogical Content Knowledge- pedagogical content knowledge is understanding how

students learn a particular subject, underlying misconceptions students may have in that

subject, and how to relate subject content to students’ everyday life.

Study

This study is composed of two parts which both have considerable limitations. Study One

used the Force Concept Inventory [FCI] instrument to determine teacher physical science content

knowledge. The FCI is a valid and reliable instrument for assessing conceptual understanding of

force and motion. The sampling size for Study One was small (n=24) which limited any findings

11

as suggestive only. Demographic information was included at the end of the instrument to

identify teacher characteristics. Correlations were identified using t-Test and ANOVA when

appropriate. A Chi-squared contingency table was used to identify correlations in terms of

knowledge thresholds.

To support any suggestive findings in Study One, a second study was implemented. As

previously described, Study Two included the participants of the 2013-2014 Texas Regional

Collaboratives for Excellence in Science and Mathematics Teaching [TRC], a state-wide

professional development program supported by The University of Texas at Austin. The TRC

collects individual demographic data on all participants as part of the participant profile, which

was used to determine population characteristics. The professional development focus for 2013-

2014 school year was on physical science Texas Essential Knowledge and Skills [TEKS] (see

Appendix A). As part of the program, Dr. Mary Urquhart of The University of Texas at Dallas

was requested to develop the TRC Physics Assessment to align with TEKS for middle school

science force and motion over a period of two months. Due to the time constraints, the

instrument was unable to undergo validity and reliability testing before implementation. The

TRC Physics Assessment was administered twice, once as a pre-test and once as a post-test. This

study only analyzed pre-test data. Individual demographic data was uniquely linked to individual

pre-tests, allowing for the analysis in this study. The sample size for Study Two was substantial

(n=368) but not necessarily representative of the Texas teacher population due to self-selection

bias for participating in the 100 contract-hour TRC professional development program.

Correlations were identified using t-Test and ANOVA when appropriate. Both studies’ results

were compared to determine any trends in the data.

CHAPTER 2

BACKGROUND

Teacher knowledge, which includes CK and PCK, directly influences student knowledge

(Sadler et al., 2013; Abell, 2007; Etkina, 2010) however which is more influential is unresolved.

Teacher CK is influenced by misconceptions, which are resilient (Trumper, 1999; Kikas, 2002;

Viennot, 1979; Solomon 1983) lasting well beyond formal education. Teacher misconceptions in

physical science have been documented in pre-service high school physics teachers (Trumper,

1999; Asikainen & Hirovonen, 2014) and in-service elementary science teachers (Burgoon et al.,

2009; Kruger, Summers, & Palacio, 1990; Ginn & Watters, 1995). Research on middle school

and high school physical science teacher misconceptions are limited and mixed, with some

research showing prevalent misconceptions (Yip et. al, 1998) while other research finding

minimal (Sadler et al., 2013). Teacher misconceptions are more prevalent in those with science

degrees not related to their field of teaching (Kind, 2014), but misconceptions have been

documented in current physics teacher holding physics degrees (Galili & Lehavai, 2006).

Nature of Scientific Misconceptions

Students form an understanding of scientific process before any formal instruction,

(National Research Council [NRC], 2005). The NRC explained further that these pre-educational

constructs can be inaccurate or incomplete, developing misconceptions in student’s knowledge

before he or she is formally trained. A scientific misconception describes a science conception

that differs from currently accepted scientific knowledge as described by Burgoon’s et al. (2009)

study on 103 Ohio elementary teachers’ physical science knowledge and correlations between

13

teacher misconceptions and student misconceptions. Kikas’ (2004) study of 198 in-service

teacher understanding of object’s motion derived that misconceptions arise as people “attempt to

understand complicated knowledge” (p. 435) as determined by an evaluation and problem task

questionnaire. These misconceptions are vast and prevalent (Poutot & Blandin, 2015; Kikas,

2002; Trumper, 1999; Asikainen and Hirovonen, 2014; Galili & Lehavai, 2006). Student

misconceptions about scientific principles have been documented in all science subjects,

(American Association for the Advancement of Science [AAAS], 1993). Gönen (2008) found

that “regardless of students’ level of schooling, misconceptions are prevalent and resistant” (p.

79) in his study of 267 pre-service science and physics teacher’s understanding of mass and

gravity as determined by open-ended physical science questions. Similarly, Galili & Lehavai’s

(2006) study of high school physics teachers’ ability to define physics concept resulted in

inadequate definitions which is indicative of misconceptions although not conclusive.

Developed misconceptions are resistant to change; students revert back to previously held

notions even when presented with contradicting evidence. Allen and Coole (2012) studied 47

pre-service teachers in England and determined that when a student is presented with content that

disagrees with his or her own understanding, the student will first rely on his or her own

understanding before accepting the new scientific process indicated by pretest and posttest of

physical science concepts. Furthermore, after treatment to correct specific misconceptions, some

participants returned to prior held misconceptions after six weeks, dropping overall post-test

corrections. Secondary physics classes fail to make lasting impact on student understanding of

physical concepts (Viennot, 1979; Solomon, 1983; Driver and Oldham, 1986).

14

Teacher Knowledge

Teacher knowledge is multifaceted and more complex than simply knowing the content

being presented. Teachers must understand the content and relate it to students in engaging and

meaningful ways. As previously stated, this study will distinguish between two types of teacher

knowledge, content knowledge referred to as CK and pedagogical content knowledge referred to

as PCK. The influence of CK and PCK are seen by Sadler’s et al. (2013) study of 181 middle

school physical science teachers and 9,506 middle school students. Students made the highest

gains from teachers with both CK and PCK over teachers with only one of the knowledge types

as determined by pretest and posttest assessment of the physical science standards of the NSES.

Similar, Etkina (2010) argues that a teacher must have “deep content knowledge (p. 020110 2)”

in order to convey conceptual understanding to students in her study of pedagogical practices of

the Rutgers Physics/ Physical Science Teacher Preparation Program. She elaborated that a

teacher must understand the history of a concept, the nuances of the concepts, and the

relationship the concept has with other scientific knowledge to convey meaning to students. She

was careful to state that this breath of knowledge was not a standalone factor, but must be

integrated into pedagogical practice to be effective. Mantyla and Nousiainen (2013) argued for

content knowledge first “because to construct teaching approaches and plans in which content

knowledge is properly organized, the teacher needs to know how the concepts can be introduced

in teaching in a logically justified manner” (p. 1584) in their study of didactic reconstructions of

physical science content to support pre-service physics teachers. Similarly, Abell (2007)

reviewed research in science teacher knowledge determined that both CK and PCK are required

for teacher preparation, but PCK is not well defined nor formally taught. (p. 1115)

15

Student achievement cannot be mastered without teachers possessing both CK and PCK,

but as to which is more influential has not been determined by current research. Deng (2007)

suggested that to understand the nature of secondary science content, the pedagogical and

sociocultural dimensions of the subject are more essential to teaching than knowing the academic

discipline in his study of academic disciplines versus school subject in relation to teacher

knowledge. This in no way means that lack of CK will lead to student success, but that the PCK

is more important. Similarly, Sander et al. (1993) found that when teachers were forced to teach

content outside their knowledge base, expert teachers would overcome knowledge deficits

without intervention but the process would take time. Novice teachers were unable to overcome

the deficit and taught to a rudimentary understanding only.

In determining student achievement in mathematics, Hill et al. (2005) found teacher

content knowledge to be a significant factor in student gains in their study of student

achievement in mathematics in115 elementary schools as indicated by interviews and

achievement testing. Arzi and White’s (2007) longitudinal study of teacher content knowledge in

teachers from pre-service to 17 years of service found that “the absence of university background

cannot be readily compensated for on-the-job textbook learning” (p. 245), and teachers’ content

knowledge does not grow linearly over time. Furthermore, teachers were often asked to teach

outside their content expertise and had persistent difficulties in subjects in which they did not

have sufficient background knowledge. Sadler et al. (2013) had similar findings, where teachers

had expertise in specific areas, but overall subject knowledge was fragmented. This

fragmentation left holes that affected student achievement of particular concepts in the same

areas.

16

Misconceptions in Teachers

With teacher CK fragmented and misconceptions being resistant to change, it is

reasonable to expect misconceptions to persist in the teacher population. Teacher misconceptions

in fundamental science concepts were first documented in the late 1930’s (Ralya & Ralya, 1938).

A shift in educational research turned attention away from teacher CK and focused on PCK until

the late 1980s (Abell, 2007). Trumper (1999) studied 25 pre-service physics teachers in Israel.

He determined that 76 percent of the physics students in the pre-service teacher training program

still maintained their prior misconceptions about forces after completing a four year program.

Berg and Brouwer’s (1991) study of 20 senior high school physics teachers found that “over one

third of the teachers held one or more alternate conception themselves” (p. 16) by open-ended

questionnaire. Hashweh (1987) found similar results in his study of content knowledge in six

experienced science teachers. He found that “almost every teacher had pre-conceptions or

knowledge inaccuracies” (p. 112) as illustrated by a free response questionnaire. Ginns and

Watters’ (1995) study of 321 pre-service elementary teachers indicated “that many prospective

elementary teachers demonstrate a range of inaccurate scientific concepts in the areas of science

that form important components of elementary science curriculum” (p. 219) as seen by an open-

ended survey. Kruger, Palacio, and Summers studied England elementary science teacher’s

physical knowledge extensively after the implementation of the 1988 Education Act (Kruger, et

al., 1990; Kruger, et al. 1992; Kruger, Summers, & Palacio, 1990). They also found a significant

amount of teacher misconceptions within elementary in-service science teacher population

regardless to any secondary physics schooling.

17

Teacher and student misconceptions are often similar. Burgoon et al. (2009) found that

elementary science teachers demonstrated the same misconceptions held by students about

gravity, magnetism, and temperature. Similarly, Cochran and Jones (1998) determined

elementary teachers have similar concepts about physical phenomena as those held by primary

students in their review of research on the nature and development of subject matter knowledge

of pre-service teachers. Sadler et al. (2013) found that when a middle school teacher did not

know the science content, he or she most likely selected the dominant student misconception as

correct. Kruger et al. 1990 study of 20 elementary in-service teachers in England reasoned that

the misuse of scientific language by teachers observed correlates with the same “undifferentiated

ideas in children” (p. 394) as indicated by in depth interviews. Kind’s (2014) study of 265 United

Kingdom pre-service teachers’ chemistry science knowledge indicated that pre-service teachers’

misconceptions about chemistry matched those of high school students determined by a 28

question survey.

Although formal education does diminish teacher misconceptions, it does not eradicate

them with certainty. Allen and Coole (2012) suggested that primary teachers’ misconceptions

remain dominant due to a lack of formal scientific education. However Gönen (2008) found both

physics and general science teachers could not explain specific concepts, even after studying

those concepts in undergraduate programs. Kind (2014) determined that a science degree was

“not enough to correct teacher misconceptions about chemistry” (p. 1336). Kind and Kind (2011)

study of 150 pre-service teachers found prevailing chemical misconceptions from a chemical

concept questionnaire. They noted that the teachers studied were designated as well-qualified

and “almost all succeeded in becoming science teachers” (p. 2149). Trumper (1999) found that

18

pre-service physics teachers do not abandon their original physical science misconceptions about

physical misconceptions, even after four years of physical science study. Similarly, Yip et al.

(1998) found that physics majors “significantly outperformed teachers in other disciplines, [but]

their performance was by no means satisfactory” (p. 322). Arzi and White (2007) found that as

teachers continued to teach, formal content knowledge of a subject was forgotten while specific

knowledge to the current curriculum remained, i.e. a middle school science teacher would forget

the college level physics learned but retain physical science material pertinent to middle school

science. Similarly, Asikainen and Hirovonen’s (2014) study of nine pre-service and 18 in-service

physics teachers found similar misconceptions about quantum mechanics examined by paper-

and-pencil test and interviews.

Influence of Teacher Content Knowledge and Teacher Misconception on Student

Achievement

Teacher CK impacts student achievement in dynamic ways. Sadler et al. (2013) found

students scored higher on physical science content questions when a teacher had high CK. In a

related study, Wayne and Young’s (2003) review of research in teacher characteristics and

student achievement gains determined that high school mathematics students learned more from

teachers who have certification in mathematics, degrees related to mathematics, and mathematics

coursework, while student performance in lower grades were inconclusive. Hill et al. (2005)

found students achieved more from teachers with strong mathematical content knowledge.

Teacher misconceptions can negatively affect student achievement. Sadler et al. (2013)

determined students with low mathematical and reading ability made no significant gains if the

19

teacher did not have the required CK. Likewise, Burgoon et al. (2009) suggested teachers who

have the same misconception as their students will be unable to address and correct their own

students’ misunderstandings. Berg and Brouwer (1991) reasoned that some misconceptions had

been passed on to students directly because “teachers expressed frustration over the difficulty in

ridding their students of what they perceived to be incorrect conceptions, which were in fact

correct” (p. 16).

Teacher Profile Education

In the United States, the majority of secondary science teachers’ bachelors’ degrees are in

biology (Hill & Gruber, 2011). According to the American Association of Physics Teachers

[AAPT] (1988), “a teacher of high school physics course should have an undergraduate

preparation in physics, mathematics, and related science equivalent to a physics major” (p.

5). Neuschatz and McFarling (2000) study of the Nationwide Survey of High School Physics

Teachers found 33 percent of the physics teachers majored in physics or physics education, but

most teachers had taken at least one college level physics course. National Center for Education

Statistics (Snyder, deBrey, & Dillow, 2016) national school survey of 2012 found that overall, 79

percent of science teacher had a science degree, but only 46 teaching physics have a degree in

physics and only 38 percent were certified to teach it. The teaching population in the United

Kingdom is similar, with a larger proportion of biology degrees versus chemistry or physics

(Kind & Kind, 2011). Australia also mimics these standards, with 86 percent of senior biology

teachers majoring in biology while only 57 percent of senior physics teachers majoring in

physics as shown by Panizzon, Westwell, & Elliott’s (2010) study of 601 South Australian

20

secondary science teachers’ responses on a six question questionnaire. Kind and Kind (2011)

study of pre-service teacher knowledge of chemical concepts noted that pre-service teachers are

required to teach both within their scientific specialty and outside their scientific specialty (p.

2127). Hill and Gruber (2011) study of teacher certification and qualification in United Stated

public and charter schools found that 57 percent of physics teachers majored in physics while 42

percent majored in another subject.

In Texas, multiple certification options are available to teach sixth grade science, seventh

grade science, eighth grade science, integrated physics and chemistry, or physics (see Table 2.1).

*A detailed table of all possible certification can be found in the Appendix B

21

Since 2015, there are 43 different certifications that fulfill requirements to teach sixth grade

science, 51 certifications for seventh grade science, 58 certifications for eighth grade, 19

certifications for integrated physics and chemistry, and 18 certifications for physics (Texas

Education Agency [TEA], 2015). Sixth grade science, seventh grade science, and eighth grade

science teachers can be certified to teach science through a generalist or core subject

certification, which requires an overall passing score of all core subjects and does not require a

specific passing science subject score (TEA, 2015). Also, sixth grade science, seventh grade

science, eighth grade science, and integrated physics and chemistry have certification options

that do not include physical science (TEA, 2015). Harrell (2010) argues that the multiple

pathways to secondary science teacher certification in Texas creates loopholes that allow

teachers to be responsible for a content they are not adequately prepared to teach indicated by her

study of 93 in-service eighth grade science teacher and their transcripts and scores on the 8-12

science TExES diagnostic examination.

CHAPTER 3

METHODOLOGY

Research Design

Sampling

Study One

Seven school districts in Dallas- Fort Worth area and two school districts in Houston area

were selected to participate in the study. Two school districts in Dallas- Fort Worth area agreed

to participate and are designated as School District A and School District B. School District A

participated in April and May of 2015. School District A has a student population of 38,600 with

28.3 percent Caucasian, 21.6 percent African American, 40 percent Hispanic or Latino, 6.9

percent Asian, with the remaining population identified as American Indian, Pacific Islander, or

two or more races. Sixth grade is housed in the elementary campuses, middle school houses

seventh and eighth grades, and integrated physics and chemistry and physics is housed in the

high schools. There were 162 potential participants identified as teaching sixth grade, seventh

grade science, eighth grade science, integrated physics and chemistry, or physics. All participants

were contacted three times to participate, once at the beginning of the study, once one week after

the beginning of the study, and once during the final week of the study. Thirty-five participants

responded and 15 participants were included in data analysis. Thirteen participants were

excluded due to an incomplete instrument, five indicated they did not currently teach one of the

science grade levels, and four indicated they either are currently teaching or have taught AP

physics in the last five years. School District B participated in April and May of 2016. School

District B has a student population of 25,500 with 14.3 percent Caucasian, 16.7 percent African

23

American, 56.3 percent Hispanic or Latino, 10 percent Asian, and the remaining population

identifying as American Indian, Pacific Islander, or two or more races. Sixth, seventh, and eighth

grade are housed on the middle school campuses and integrated physics and chemistry and

physics are housed on the high school campuses. A total of 71 potential District B participants

were identified as teaching sixth grade science, seventh grade science, eighth grade science,

integrated physics and chemistry, or physics. All participants were contacted three times to

participate, once at the beginning of the study, once two weeks after the beginning of the study,

and once during the final week of the study. Twenty-seven participants responded and nine

participants were included in data analysis. Nine participants were excluded due to an incomplete

instrument, one indicated he did not currently teach one of the science grade levels, seven

indicated they have been the teacher of record for AP physics in the last five years, and one

indicated he had been the teacher of record for an IB course in the last five years. In total,

responses from 24 participants, 15 from District A plus nine from District B, were included in

data analysis.

Study Two

An optional professional development community is the Texas Regional Collaborative

for Excellence in Science and Mathematics Teaching, referred to as the TRC for the remainder of

this work. The TRC is a collaboration program developed and maintained through The

University of Texas at Austin STEM program. In 2013-2014 school year, the TRC had 30 TRC

Science Collaboratives that were housed primarily at either Texas Educational Region Service

Center offices or universities throughout the state. In order to participate in a Regional Science

24

Collaborative, in-service science teachers in public, charter, or private schools must agree to 100

hours of professional development offered through his or her Collaborative during the 15 month

grant term. Professional development must be approved by the TRC in the individual

Collaborative grant application process, and be aligned to the specific content TEKS identified

by the TRC in consultation with the Texas Education Agency (Texas Regional Collaborative for

Excellence in Science and Mathematics Teaching, 2013). For the 2013-2014 school year, the

TRC focus was physical science, including Newton’s three laws of motion. In 2013-2014 grant

year, there were 753 possible participants identified as teachers of record for sixth grade science,

seventh grade science, eighth grade science, integrated physics and chemistry, or physics

courses. Of the 753 identified participants, 368 participants were included in the study. Of the

participants excluded, 235 participants did not have any pre-test instrument information available

and 150 participants did not complete the pre-test instrument in its entirety.

Instrumentation

Study One

Content Knowledge Instrument One

The Force Concept Inventory (Hestenes, Wells, & Swackhamer, 1992), referred to as the

FCI for the remainder of this study, was administered to identify teacher content knowledge

(Jackson, 2016). The FCI is a vetted instrument to identify student conceptual knowledge of

physical science (Hestenes & Halloun, 1995). Sadler et al. (2013) suggested using similar tests

designed to determine student content knowledge as a more appropriate measure to determine

teacher knowledge than other measures like college course, GPA, degrees, or certifications. The

FCI is used in its entirety. FCI questions that identify conceptual knowledge of Newton’s three

25

laws of motion are extrapolated to identify teacher content knowledge to each law. These

divisions are consistent with Poutot and Blandin (2015) use of the FCI to determine student

misconceptions, with an analysis of the overall concept and not individual scores (see Table 3.1).

Table 3.1. FCI Question Breakdown by Newton’s Laws

Newton’s First Law of Motion 10, 11, 13, 23, 24

Newton’s Second Law of Motion 17, 21, 22, 25, 26, 27, 29

Newton’s Third Law of Motion 4, 15, 16, 28

Demographic Survey One

A demographic survey, referred to as the DS, collected further information for teacher

characteristics comparison. Data was collected on the following characteristics: participant’s sex,

years of service, current teaching position, highest earned degree, undergraduate majors and

minors, type of degree program, and Texas certifications. The DS was modeled after the

National Census survey to convey confidence and accuracy in data collection. The DS is 10

questions in length with multiple choice and free response when appropriate (see Appendix C).

Study Two

Demographic Survey Two

Participants who wish to fully participate in the TRC must complete a participant profile

that identifies the following teacher characteristics: participant’s sex, ethnicity, highest degree

earned, years of service, if the participant has a STEM major, type of certification program, years

26

of participation in the TRC, teaching position for the 2013-2014 school year, grades or subjects

taught by the participant in the 2013-2014 school year, and demographic information about the

student population taught by the participant. The TRC location is also recorded by region. For

this study, the following teacher characteristics were assessed: region, participant’s sex, highest

degree earned, years of service, STEM major, and grades or subjects taught by the participant.

Questions are multiple choice and free response when appropriate (see Appendix D).

Content Knowledge Instrument Two

The TRC requested that Dr. Mary Urquhart of The University of Texas at Dallas, A TRC

Science Collaborative Project Director and physics educator, create a pre/post assessment for

assessing teacher content knowledge of force and motion. Dr. Urquhart recommended the use of

the FCI, but the TRC required the assessment to align to specific middle school physics Texas

Essential Knowledge and Skills [TEKS] identified as low performing on the eighth grade State

of Texas Assessment of Academic Readiness [STAAR] test for the spring 2013 administration

(see Table 3.2).

Table 3.2. TEKS Identified as low performing

Grade Level TEKS

Sixth Grade Science 6.8 A 6.8 C

Eighth Grade Science 8.6 B

For a complete description of the TEKS, see Appendix E

27

Each of the TEKS had been identified by the Texas Education Agency as low performing on the

middle school (eighth grade) science STAAR. Dr. Urquhart created the TRC Physics

Assessment as requested, with the understanding that the two month development time frame did

not allow for validity and reliability testing (Urquhart, M., e-mail, April 4, 2017).

The TRC Physics Assessment is a multiple choice instrument without the option to select

multiple answers to specific questions (see Appendix F for sample questions from the

instrument). The TRC permitted Dr. Urquhart to include short answer explanations of a subset of

multiple choice selections. Only answers to the multiple choice questions were analyzed in this

study. The author created questions in the instrument from her experience with the FCI, the

Force and Motion Conception Evaluation [FMCE] (Thornton & Sokoloff, 1998), and conceptual

questions used in the context of her own Master of Arts in Teaching Conceptual Physics I: Force

and Motion course for think-pair-share or homework assignment (Urquhart, M., e-mail, April 4,

2017). The TRC also requested additional questions that reflected content in the Making Sense

of Science: Force and Motion (Daehler, K. R., Shinohara, M., & Folsom, J., 2011) professional

development course used by most 2013-2014 TRC Science Collaboratives in their Summer

Institutes. Dr. Urquhart vetted the instrument through Master Teachers in the UTeach Dallas

Secondary Science and Mathematics Teacher Preparation program, a local high school physics

teacher, and other UT Dallas physics faculty. At least one content expert affiliated with the TRC

and the TRC staff also vetted the TRC Physics Assessment before administration to the TRC

participants (Urquhart, M, e-mail, April 4, 2017). TRC Physics Assessment questions that

identify conceptual knowledge of physics and Newton’s three laws of motion are extrapolated to

identify teacher content knowledge to each law (see Table 3.3).

The TRC administered this test twice, initially as a pre-test before the initiation of the TRC

professional development programs and again as a post-test at closing of the collaborative grant

year. For this study, only pre-test data is analyzed.

Data Analysis

Study One

Participants were awarded one point for each correct answer on the FCI. Overall scores

were averaged to determine individual participant’s scores. Scores were recorded to two

significant figures to correspond with traditional numerical grade point scales. Scores for

Newton’s first, second, and third law were extrapolated and averaged as a subset to determine

individual participants’ scores for each category. Participants’ were also divided into knowledge

groups based on average FCI score. Hestenes and Halloun (1995) divide student scores using the

FCI into three knowledge categories; mastery threshold for scores 85 percent or higher, entry

threshold for scores between 60 percent and 85 percent, and scores below 60 percent outside of

29

these ranges. Using this model, participants who earned an overall average of 85 percent or

higher showed sufficient content knowledge in Newtonian mechanics and the participants mostly

likely have few misconceptions. Participants who earned between 60 percent and 85 percent

showed a general understanding of Newtonian mechanics but the participants mostly likely have

some misconceptions. Participants who earned less than 60 percent have insufficient knowledge

of Newtonian mechanics and most likely have major misconceptions.

Teacher characteristics fall into ten categories: participant’s sex, years of service in

teaching, current school district, current teaching position, highest earned degree, undergraduate

major, undergraduate STEM course work, earned graduate degree, teaching certification type,

and teaching certification subject as identified by the demographic survey one. Participants’

recorded majors and minors were combined to determine undergraduate STEM course work.

Participants’ degree program is excluded due to the wide variety in degree programs offered at

each university. Years of service in teaching are classified as one to five year, six to ten years, or

eleven or more years. Current teaching positions are classified as sixth grade, seventh grade,

eighth grade, and high school. Highest earned degrees are classified as bachelor, masters, and

doctorate. Undergraduate majors are categorized as STEM (science, technology, engineering, or

math), education, or other not listed. Undergraduate STEM course work is categorized as a

major or minor in a STEM field or other. STEM coursework is identified as a field of natural

science, for example veterinarian science, physics, or biology. Teaching certification type is

categorized as traditional or alternative. Teaching certification subject is categorized as general

science, general education, or other not specified. Education coursework is identified as a field of

30

education including science education, for example middle school science education or bilingual

education.

Significance of results is established using a variety of statistical tools. A t-test is applied

for the following teacher characteristics tests versus FCI percentage score to determine a p-value:

participant’s sex, school district, highest earned degree, undergraduate STEM course work, and

teaching certification type. Significance of results is established using an ANOVA test for the

following teacher characteristics tests versus FCI percentage score to determine a p-value: years

of service, current teaching position, undergraduate major, and teaching certification subject (see

Appendix G). A Chi-squared contingency table is applied to teacher characteristics tests versus

knowledge groups to determine a p-value. The null hypothesis in all categories is there is no

relationship between teacher characteristics and FCI score.

An original alpha value of 0.05 is established. However, when calculating large amounts

of statistical tests using the same data, it is more likely to reject the null hypothesis when it is in

fact true (Abdi, 2010). To compensate for this risk, a Holm Bonferroni Sequential Correction

post-hoc statistical test is applied to adjust the p-values to compensate for the large number of

comparisons. The adjusted p-values are then compared against the original alpha to determine

statistical significance. An excel calculator developed by Gaeteno (2013) is used to determine the

adjusted p-value.

Study Two

Participants were awarded one point for each correct answer on the TRC Physics

Assessment. Overall scores were averaged to determine individual participant’s scores. Scores

31

were recorded to two significant figures to correspond with traditional numerical grade point

scales. Scores were extrapolated using only questions about conceptual forces and averages as a

subset to correspond with the makeup of the FCI. Scores for Newton’s first, second, and third

law were extrapolated and averaged as a subset to determine individual participant’s scores for

each category.

Teacher characteristics fall into seven categories: region, participant’s sex, years of

service in teaching, current teaching position, highest earned degree, undergraduate STEM

degree, and certification method as identified by demographic survey two. Region is defined by

the twenty regions established by Texas Education Agency [TEA]. Any TRC Science

Collaborative housed at a college or university was identified by physical location and included

in the appropriate region. Region type is defined as rural, independent, and urban based off

population size provided by Public Education Information Management System [PEIMS] (Public

Education Information Management System, 2017) for the 2013-2014 school year. Rural regions

have less than 100,000 students, independent regions have at least 100,000 but less than 300,000

students, and urban regions have at least 300,000 students. Years of service in teaching are

classified as zero to four years, five to nine years, ten to fourteen years, fifteen to nineteen years,

twenty to twenty four years, twenty five to twenty nine years, or thirty to thirty five years.

Current teaching positions are classified as sixth grade, seventh grade, eighth grade, middle

school science, integrated physics and chemistry, physics, two or more high school subjects, two

or middle school subject, or both middle and high school subjects. Middle school subjects are

defined as sixth grade science, seventh grade science, and eighth grade science. High school

subjects are defined as integrated physics and chemistry and physics. Highest earned degrees are

32

classified as bachelor, masters, and doctorate. Teaching certification type is categorized as

traditional and alternative.

Significance of results is established using a variety of statistical tools. A t-test is applied

for the following teacher characteristic tests versus TRC instrument percentage score to

determine a p-value: participant’s sex, highest earned degree, undergraduate STEM major, and

teaching certification type. Significance of results is established using an ANOVA test for the

following teacher characteristic tests versus TRC instrument percentage score to determine a p-

value: region, years of service, and current teaching position (see Appendix H). The null

hypothesis in all categories is there is no relationship between demographic information and

TRC instrument score. As with Study 1, an original alpha value of 0.05 is established and a

Holm Bonferroni Sequential Correction (Abdi, 2010) is applied to adjust the p-values to

compensate for the large number of comparisons. An excel calculator is used to determine the

adjusted p-value (Gaeteno, 2013).

The following statistical tests proved significant after the Holm Bonferroni Sequential

Correction: Overall FCI vs Grades Taught ANOVA, Newton’s third Law vs Grades Taught

ANOVA, and Newton’s Third Law vs Grades Taught Chi-squared Continencey Table.

A one-way between subjects ANOVA was conducted to compare the effect of grade level

taught on FCI overall average in sixth grade, seventh grade, eighth grade, and high school

conditions. There was a significant effect of grade level taught on FCI overall average at the p

<.05 level and adjusted by Holm-Bonferroni Sequential Correction for the four conditions [F (3,

12) = 11.9, p = 0.00107, p’ = 1.63E-6] (see Table 4.9).

Post hoc comparisons using the Tukey post-hoc test indicated that the mean score for High

school (M=0.792, SD = 0.14) is significantly different from the mean score for sixth grade

(M=0.253, SD = 0.12), the mean score for high school is also significantly different from the

mean score for seventh grade (M=0.338, SD = 0.13), and is significantly different from the mean

score for eighth grade (M=0.524, SD = 0.186). Eighth grade is significantly different from mean

score for sixth grade. However, there is no significant difference in means between sixth grade

0.008 (see Table 4.15).

The most common score is 44 percent with a range of nine percent to 91 percent. The frequency

of scores is slightly skewed to the right (see Figure 4.5), which shows that more participants

scored below 50 percent.

The average for conceptual force questions of TRC Physics Assessment is 47 percent

There is no significant difference in means between any other conditions. Region type has a

limited correlation with physics knowledge in reference to the TRC Physics Assessment overall.

Those teachers who teach in urban regions in this sample have more physics knowledge than

teachers who teach in independent regions. However, there is no significant effect for teachers

who teach in rural regions.

An independent-samples t-test was conducted to compare the TRC Physics Assessment

overall averages in male and female conditions. There was a significant difference in scores for

males (M=0.500, SD =0.16) and females (M=0.430, SD=0.13) conditions after Holm-Bonferroni

correction; t (108) = -3.488, p = 3.53E-4, p’ = 0.0162 (see Table 4.24 and 4.25).

These results suggest that participant’s sex in this sample correlates with physics knowledge in

reference to the TRC Physics Assessment. Specifically, male teachers in this sample have more

physics knowledge than female teachers.

An independent-samples t-test was conducted to compare the TRC Physics Assessment

overall averages in STEM major and non-STEM major conditions. There was a significant

majors, although both averages are below 50 percent.

A one-way between subjects ANOVA was conducted to compare the effect of grades

taught on TRC Physics Assessment overall average in middle school science, high school

science, and both middle school and high school science condition. There was a significant effect

statistically more knowledgeable than other subjects, and combined middle and high school

teachers are statically more knowledgeable than middle school science teachers. This suggests

that teaching at least one high school science course is related to increased teacher physical

science knowledge.

A one-way between subjects ANOVA was conducted to compare the effect of grades

than eighth grade science teacher, even those eighth grade science teachers who also teach at

least one high school science course. This suggests that teaching only high school is related to an

increase in physics knowledge over teaching eighth grade science.

physics and chemistry teachers. This suggests that teaching at least one physics course in a high

school only setting is related to increased conceptual knowledge of physics.

An independent-samples t-test was conducted to compare Newton’s first law questions

from the TRC Physics Assessment in STEM major and non-STEM major conditions. There was

a significant difference in scores for STEM major (M = 0.507, SD = 0.23) and non-STEM major

(M = 0.433, SD = 0.22) conditions after Holm-Bonferroni correction, t (346) = 3.087,

p=0.00109, p’=0.0448 (see Table 4.46 and 4.47).

teachers in this sample have a better understanding of Newton’s second law than eighth grade

Grade level taught correlates with understanding on Newton’s second law in reference to the

TRC Physics Assessment Newton’s second law questions averages. Taken together, physics

teachers in this sample have a statistically better understanding of Newton’s second law than

sixth grade, seventh grade, eighth grade, integrated physics and chemistry, and teachers

responsible for two or more subject courses. Teachers who teach integrated physic and chemistry

and physics have a statistically better understanding of Newton’s second law than teachers who

only teach integrated physics and chemistry and teacher who teach more than two middle school

sciences. This suggests teaching only physics correlates with an increase in teacher

understanding of Newton’s second law while teaching at least one physics course in high school

has a limited impact.

(M=1.000, SD = 0.00) is significantly different from the mean scores for all other regions.

However, a standard deviation of zero suggests a duplication of scores. There is no significant

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

Summary of results

The statistical tests for both the FCI and the TRC Physics Assessment have averages

below mastery level, showing the majority of the teachers have misconceptions Newtonian

mechanics (see Figure 5.1).

Figure 5.1. Results Flow Chart

83

Newton’s Third law was found to be the lowest scoring section for both the FCI and TRC, with

the most frequent score of 25 percent for the FCI and 20 percent for the TRC Physics

Assessment. For both studies, grades taught were consistently statistically significant. Teachers

of physics out-performed teachers of other subjects except with regard to the TRC Physics

Assessment third law questions. Grades taught was significant only for overall averages and the

Newton’s third law questions of the FCI. However, for the FCI, the low participant number

meant teachers of physics and teachers of integrated physics and chemistry could not be

distinguished, which is less comparative to the TRC Physics Assessment.

Several teacher characteristics were significant for the TRC Physics Assessment but not

significant for the FCI: region, region type, participant’s sex, and STEM major. Although there

was no significant difference between school districts, participant’s sex, or STEM major for the

FCI, both school districts were part of Region 10, an urban region that had higher overall scores

on the TRC than other regions. Males scored higher than females on the TRC, which is

consistent with current research on gender in STEM fields as explained by Weinburgh (1995)

meta-analysis of gender attitudes in science, but also has a large difference in group size (male =

79; female =289), which could skew the results. The TRC Physics Assessment for third law

question was significant when comparing rural regions. However, this comparative is potentially

misleading. The region that scored significantly higher than other regions had a standard

deviation of zero, which may suggest duplicate responses and therefore not be representative of

the region as a whole.

84

Conclusion

Based on the findings of this study, the majority of Texas science teachers responsible for

teaching physical science have not mastered at least a portion of the physical science content

they are teaching. These findings appear state-wide and cross sex of teacher, location, years of

service, STEM education, and certification. Teachers in this study had particular difficulty with

questions on Newton’s third law of motion.

In this study, teachers of physics demonstrated a better understanding than teachers of

other science courses, but on average, did not reach the mastery level of conceptual knowledge

in Newtonian mechanics according to the FCI and TRC Physics Assessment. The lack of

knowledge corresponds to the Neuschatz and McFarling (2000) findings on the low number of

physics teachers who majored in physics. Without a large number of teachers with physics

degrees in the teacher population, there is a higher likelihood that misconceptions will be

embedded in the curriculum presented to the students (Burgoon et al., 2009).

Middle school teachers were the lowest performing group, suggesting this teacher

population has the most misconceptions. This corresponds with the finding of the Harrell (2010)

study on eighth grade science teachers in Texas, suggesting that the loophole in certification for

middle school science is allowing physical science to be taught by unprepared teachers. A

prevalence of misconceptions among middle school teachers is particularly concerning because

according to the TEKS, sixth grade science introduces force and motion in terms of Newton’s

three laws of motion and eighth grade science continues these concepts which are then tested on

the state assessment (see Appendix M). If these teachers have insufficient knowledge of physical

85

science content, then their students are likely to have major misconceptions that will have to be

addressed in physics before students are able to be successful (Berg & Brouwer, 1991).

Equally concerning is the impact of years of service. There is no indication in this study

that years of service impact overall knowledge of physical science. This suggests that teachers

are continuing to teach physical science with insufficient knowledge of the content. The students

of these teachers continue to build misconceptions year after year, as long as the teacher is active

in his or her career.

Limitations

It is important to note that Study One using the FCI has a small sample size (n=24) which

makes findings suggestive but not conclusive. A possible influencing factor is that teacher

participation in Study One for School Districts A and B was strictly voluntary without provided

incentives. In Study Two, the TRC Physics Assessment did not undergo reliability and validity

testing before implementation due to time constraints in its creation, although it assessed similar

concepts to the FCI. The TRC demographic survey identified participants as either earning a

degree with a STEM major or not, but did not give specific information as to the undergraduate

major. The TRC demographic survey also did not collect information about current teacher

certificates held by each participant. The participants in the TRC are not necessarily

representative of the entire Texas teacher population. The TRC requires 100 hours of

professional development over the school year, which deters some teachers from participating.

The TRC also offers incentives for joining, such as stipends, classroom supplies and resources,

free technology instruments, or scholarship money for graduate coursework. These incentives

86

create a self-selection bias in the sample, particularly with regards to motivation and amount of

prior professional development.

Recommendations

Based on the findings and conclusions in this study, the following recommendations are

offered.

1. Middle school science teacher certification should be limited to a science certification

that includes physical science.

2. Physical science curriculum presented should address specific facets on Newton’s third

law in order to correct teacher misconceptions.

3. Physics teachers can serve as mentors for physical science content knowledge, as they are

the most likely to understand it.

4. Teachers of record for middle school science, integrated physics and chemistry, and

physics should have specialized professional development in Newton’s laws from a

physics education expert to correct teacher misconceptions regardless of years of service.

Future Research

This study was able to show that the majority of science teachers do not understand at

least some of the physical science content they are teaching. However, this study is unable to

indicate what specific misconceptions regarding Newton’s laws of motion this teacher

population has and how best to combat them. Future research into why teachers chose specific

incorrect answers would be insightful for building a professional development to correct teacher

87

knowledge. This study focused on physical science, but similar trends may appear in other

subjects, specifically chemistry and earth science. Some research has suggested similar trends

(Kind, 2014), but these should be explored more thoroughly. Middle school science has the most

certification routes that do not require physical science knowledge, especially in sixth grade. A

study between specific middle school certifications and teacher knowledge needs to researched,

but is beyond the scope of this study.

TEXAS ESSENTIAL KNOWLEDGE AND SKILLS [TEKS] RELATED TO FORCE

AND MOTION IN MIDDLE SCHOOL AND HIGH SCHOOL

Sixth Grade Science

Grade 6 Strand- 6.4 C Force, motion, and energy.

Energy occurs in two types, potential and kinetic, and can take several forms. Thermal energy

can be transferred by conduction, convection, or radiation. It can also be changed from one

form to another. Students will investigate the relationship between force and motion using a

variety of means, including calculations and measurements.

Knowledge and Skills 6.8 Force, motion and energy

The student knows force and motion are related to potential and kinetic energy. The student is

expected to:

(A) compare and contrast potential and kinetic energy;

(B) identify and describe the changes in position, direction, and speed of an object when acted

upon by unbalanced forces;

(C) calculate average speed using distance and time measurements;

(D) measure and graph changes in motion; and

(E) investigate how inclined planes and pulleys can be used to change the amount of force to

move an object.

Seventh Grade Science

Grade 7 Strand- (C) Force, motion, and energy.

Force, motion, and energy are observed in living systems and the environment in several ways.

Interactions between muscular and skeletal systems allow the body to apply forces and

transform energy both internally and externally. Force and motion can also describe the

direction and growth of seedlings, turgor pressure, and geotropism. Catastrophic events of

weather systems such as hurricanes, floods, and tornadoes can shape and restructure the

environment through the force and motion evident in them. Weathering, erosion, and

deposition occur in environments due to the forces of gravity, wind, ice, and water.

89

Knowledge and Skills 7.7 Force, motion, and energy

Seventh Grade Science Continued

The student knows that there is a relationship among force, motion, and energy. The student is

expected to:

(A) contrast situations where work is done with different amounts of force to situations where

no work is done such as moving a box with a ramp and without a ramp, or standing still;

(C) demonstrate and illustrate forces that affect motion in everyday life such as emergence of

seedlings, turgor pressure, and geotropism.

Eighth Grade Science

Grade 8 Strand- (C) Force, motion, and energy.

Students experiment with the relationship between forces and motion through the study of

Newton's three laws. Students learn how these forces relate to geologic processes and

astronomical phenomena. In addition, students recognize that these laws are evident in

everyday objects and activities. Mathematics is used to calculate speed using distance and time

measurements.

Knowledge and Skills 8.6 Force, motion, and energy.

The student knows that there is a relationship between force, motion, and energy. The student

is expected to:

(A) demonstrate and calculate how unbalanced forces change the speed or direction of an

object's motion;

(B) differentiate between speed, velocity, and acceleration; and

(C) investigate and describe applications of Newton's law of inertia, law of force and

acceleration, and law of action-reaction such as in vehicle restraints, sports activities,

amusement park rides, Earth's tectonic activities, and rocket launches.

Integrated Physics and Chemistry

Knowledge and Skills IPC.4 Science Concepts

The student knows concepts of force and motion evident in everyday life. The student is

expected to:

(A) describe and calculate an object's motion in terms of position, displacement, speed, and

acceleration;

90

Integrated Physics and Chemistry Continues

(B) measure and graph distance and speed as a function of time using moving toys;

(C) investigate how an object's motion changes only when a net force is applied, including

activities and equipment such as toy cars, vehicle restraints, sports activities, and

classroom objects;

(D) assess the relationship between force, mass, and acceleration, noting the relationship is

independent of the nature of the force, using equipment such as dynamic carts, moving

toys, vehicles, and falling objects;

(E) apply the concept of conservation of momentum using action and reaction forces such as

students on skateboards;

(F) describe the gravitational attraction between objects of different masses at different

distances, including satellites; and

(G) examine electrical force as a universal force between any two charged objects and

compare the relative strength of the electrical force and gravitational force.

Physics

Knowledge and Skill Physics (4) Science concepts.

The student knows and applies the laws governing motion in a variety of situations. The

student is expected to:

(A) generate and interpret graphs and charts describing different types of motion, including

the use of real-time technology such as motion detectors or photogates;

(B) describe and analyze motion in one dimension using equations with the concepts of

distance, displacement, speed, average velocity, instantaneous velocity, and acceleration;

(C) analyze and describe accelerated motion in two dimensions using equations, including

projectile and circular examples;

(D) calculate the effect of forces on objects, including the law of inertia, the relationship

between force and acceleration, and the nature of force pairs between objects;

(E) develop and interpret free-body force diagrams; and

(F) identify and describe motion relative to different frames of reference.

Knowledge and Skills Physics (5) Science concepts.

The student knows the nature of forces in the physical world. The student is expected to:

(B) describe and calculate how the magnitude of the gravitational force between two objects

depends on their masses and the distance between their centers;

(C) describe and calculate how the magnitude of the electrical force between two objects

depends on their charges and the distance between them;

(D) identify examples of electric and magnetic forces in everyday life;

(H) describe evidence for and effects of the strong and weak nuclear forces in nature.

are involved in this collision, which is producing the Himalayas. Both plates put a colliding

resistive force, FCR, on each other. The magnitude of the force FCR the Indian Plate exerts

on the Eurasian Plate is:

A) Greater than the magnitude of the force FCR exerted by the Eurasian Plate because the

Indian Plate is colliding into the Eurasian Plate.

B) Greater than the magnitude of the force FCR exerted by the Eurasian Plate because the

Indian plate is moving faster than the Eurasian Plate.

C) Less than the magnitude of the force FCR exerted by the Eurasian Plate because the Indian

Plate is thinner than the Eurasian Plate.

D) Less than the magnitude of the force FCR exerted by the Eurasian Plate because the

Eurasian Plate is more massive than the Indian Plate.

E) Equal to the magnitude of the force FCR exerted by the Eurasian Plate because the two

plates are pushing against each other.
