- Abstract
Despite increasing demands for skilled workers within the technological domain, there is still a deficit in the number of graduates in computing fields (computer science, information technology, and computer engineering). Understanding the factors that contribute to students' motivation and persistence is critical to helping educators, administrators, and industry professionals better focus efforts to improve academic outcomes and job placement. This article examines how experiences contribute to a student's computing identity, which we define by their interest, recognition, sense of belonging, and competence/performance beliefs. In particular, we consider groups underrepresented in these disciplines, women and minoritized racial/ethnic groups (Black/African American and Hispanic/Latinx). To delve into these relationships, a survey of more than 1,600 students in computing fields was conducted at three metropolitan public universities in Florida. Regression was used to elucidate which experiences predict computing identity and how social identification (i.e., as female, Black/African American, and/or Hispanic/Latinx) may interact with these experiences. Our results suggest that several types of experiences positively predict a student's computing identity, such as mentoring others, having a job, or having friends in computing. Moreover, certain experiences have a different effect on computing identity for female and Hispanic/Latinx students. More specifically, receiving academic advice from teaching assistants was more positive for female students, receiving advice from industry professionals was more negative for Hispanic/Latinx students, and receiving help on classwork from students in their class was more positive for Hispanic/Latinx students. Other experiences, while having the same effect on computing identity across students, were experienced at significantly different rates by females, Black/African American students, and Hispanic/Latinx students. The findings highlight experiential ways in which computing programs can foster computing identity development, particularly for underrepresented and marginalized groups in computing.

- Abstract
The power of knowledgeable peers (in this case undergraduate learning assistants [LAs]) to scaffold learning in ways that can positively influence both cognitive and affective outcomes in science, technology, engineering, and mathematics (STEM), is explored in this study. In terms of the cognitive perspective, we use a metacognitive awareness (MA) framework for which the MA indicator predicts course performance. For the affective perspective, we use a disciplinary identity (DI) framework for which the DI indicator predicts discipline-specific persistence. A survey that included these indicators as well as students' experiences in STEM classes was administered to over 2000 students. Multiple regression models reveal student experiences (individually and socially) as predictors of MA and DI. Certain social learning experiences (e.g., explaining to others when the LA is present) were found to be more predictive of MA than individual learning experiences. This result provides evidence to suggest that collaborative environments may align with increased metacognitive processes. Social learning experiences (e.g., explaining to the LA) were also found to be positive and significant predictors of DI but with a smaller effect than for MA. Fully participating in group activities was found to be a significant and positive predictor of both outcomes. This study provides further evidence for the importance of active learning (both individually and socially) for both cognitive and affective outcomes as well as the growing role that LAs can play to enhance these outcomes.

- Abstract
Both in physics education and in science education more generally concerns exist that formal K-12 education structures limit and, in some cases, diminish students' interest and agency in these fields. Many stakeholders have turned to informal learning experiences as a means to inspire young people to pursue continual learning in these fields in ways that foster creativity and self-determination. While research exists on the effect of these informal science experiences on students' science identities and broader science, technology, engineering, and math (STEM) identities, little is known about how specific informal science education experiences relate to students' "physics identity"--a construct strongly associated with physics career choice. The current study contributes to the literature by examining the effect of several informal science experiences on students' physics identity. Drawing on data from a national survey administered to students in required English courses at 27 colleges and universities across the US (N=15 847), we used multiple regression to test the relationship between informal science experiences in various topical areas at two educational levels (K-8 and 9-12) and students' physics identity, while controlling for science background and demographics. The results reveal positive effects for stereotypic informal experiences in physical science (e.g., tinkering, competitions) as well as for talking science with friends or family. In addition, there were negative relationships between biology-related experiences (at both levels) and physics identity. Group comparisons further revealed that female students were more likely to report participating in biology-related activities and less likely to report participating in tinkering, STEM competitions, and talking science with friends or family. Students who identified themselves as Black or Hispanic were also less likely than those of other racial or ethnic groups to report tinkering and talking science with friends or family. We use this evidence to build the case that informal learning experiences in physics should move beyond stereotypic activities, increase accessibility, facilitate discourse with family or friends, and focus on interdisciplinary experiences that better engage young participants with a wide range of interests that are connected to physics.

Cohen, Susie M., Hazari, Zahra, Mahadeo, Jonathan, Sonnert, Gerhard, and Sadler, Philip M.
- Abstract
It is well known that women are underrepresented in science. technology engineering and mathematics (STEM) and that their interest declines more steeply over the schooling years. As such, this study uses a STEM identity theoretical framework to examine the effects of early STEM experiences, focusing particularly on experiences that may be more formative for female students. Given that early experiences are a form of capital, the study is also guided by nuanced perspectives on STEM capital and STEM identity capital. The data used were drawn from surveys administered to 15,725 college students. Blocked regression models were utilized and the results indicated a significant effect on STEM identity for students who reported encouragement in STEM from elementary school teachers, using STEM toys/kits, watching STEM-related TV programs or movies, playing STEM computer/video games, and observing or studying stars and other astronomical objects. Negative experiences included baking/cooking/kitchen chemistry and writing about STEM. To examine which of these experiences had long-lasting impact in the face of intervening experiences in middle/high school, controls were provided for middle/high school STEM interest. This indicated early experiences that translated to STEM identity capital in the future. Only observing stars became nonsignificant, while the other early experiences likely contributed to STEM identity capital. The findings highlight early experiences that can be formative for STEM identity years later (i.e., STEM identity capital) despite intervening years of changing STEM interest. As such, the results provide both practical and theoretical insight into understanding the development and maintenance of STEM identity.

6. College Students' Mathematics-Related Career Intentions and High School Mathematics Pedagogy through the Lens of Identity

Cribbs, Jennifer, Hazari, Zahra, Sonnert, Gerhard, and Sadler, Philip M.
- Abstract
We expand on prior qualitative research about mathematics identity development using data from a large national US survey of 10,437 students in 336 college calculus classes. Multinomial logistic regression models find that a stronger mathematics identity predicts higher student interest in pursuing certain STEM careers when compared with non-STEM careers, particularly those in physical and computer sciences, engineering, and mathematics, or in science or mathematics teaching. Multiple linear regression models identify that certain instructional practices employed by high school mathematics teachers predict higher levels of students' mathematics identity. These include a high amount of interaction within the classroom, a focus on mathematics connections, and activities involving conceptual learning. Surprisingly, the role of the textbook, ways of organizing students (individual, small group, whole class), forms of assessment, and use of calculators or computers did not significantly predict students' mathematics identity.

- Abstract
Understanding the rate at which STEM faculty move from traditional, lecture-intensive teaching practices to more effective, student-centered practices and the institutional conditions that favor this shift are crucial for supporting faculty change. This study investigated the instructional practices of biology, chemistry, and physics faculty at research-intensive institutions and explored the institutional structures that support student-centered instruction. Faculty members (N = 1,456) from 66 institutions reported on their frequency of use of a variety of instructional practices (at two time points within the last five years) and the support structures present at their institution using the Change in Implementation of Pedagogical Practices (ChIPP) survey. An index was created for measuring use of student-centered instructional strategies at these two time points, providing a measure of change over time. About 30% of all respondents reported increases in the frequency of student-centered teaching strategies over time. For all faculty, participation in institutional faculty communities was predictive of change toward student-centered pedagogies. Faculty teaching lower-division courses were more likely to use at a higher number of student-centered strategies every class, compared to their upper-division colleagues. Factors associated with greater use of student-centered strategies in lower-division courses were institutional financial opportunities for course reform, use of classrooms designed to promote active learning, and engagement in STEM education research. Only one factor, engagement in professional development, was associated with greater use of student-centered strategies in upper-division courses. These findings suggest that pedagogical change is occurring at research-intensive institutions and may be fostered through specific support structures.

Indorf, Jane L., Benabentos, Rocio, Daubenmire, Patrick, Murasko, Donna, Hazari, Zahra, Potvin, Geoff, Kramer, Laird, Marsteller, Pat, Thompson, Katerina V., Cassone, Vincent M., and Stanford, Jennifer S.
- Abstract
Despite decades of research indicating that active learning techniques (ALTs) are more effective than traditional lecture, ALTs are not widely implemented in STEM undergraduate classrooms. While ALT implementation is happening in a number of disciplines, including the geosciences, most STEM teaching remains lecture-based. Understanding the contexts that correlate with ALT adoption may allow expanded implementation. ALT use was documented among STEM pre-tenure and tenured faculty respondents across 66 research-intensive, U.S. universities, using the Change in Implementation of Pedagogical Practices survey. Personal, professional, and institutional/departmental factors were analyzed for association with ALT use. Most respondents reported using some ALTs in their teaching, with no significant distinctions between pre-tenure and tenured faculty. Teaching was perceived to carry less weight in practice (e.g., in tenure and promotion decisions) than the theoretical value stated by institutions (e.g., in faculty assignments and hiring). ALT use among tenured faculty was predicted by number of recent publications, their knowledge of education initiatives, and receiving informal feedback on their teaching. ALT use among pre-tenure faculty was predicted by the number of STEM education talks given. Perception of obstacles was a negative predictor of ALT use among tenured faculty only, though both pre-tenure and tenured faculty identified barriers to ALT use. Considering these identified barriers and how to remove them could potentially increase ALT use. The findings that ALT use by tenured faculty was predicted by number of recent publications and that grant funding was neither a positive nor negative predictor of ALT use suggest that ALT use does not hinder faculty research productivity.

9. The Context Dependence of Physics Identity: Examining the Role of Performance/Competence, Recognition, Interest, and Sense of Belonging for Lower and Upper Female Physics Undergraduates

Hazari, Zahra, Chari, Deepa, Potvin, Geoff, and Brewe, Eric
- Abstract
While there is a growing body of work that examines disciplinary identity development, unlike qualitative work in this area, quantitative research has not fully incorporated the importance of different contexts, nor has it uniquely focused on underrepresented groups (in this case, women in physics). This study examines how the constructs posited by prior work as important for physics identity, as well as an additional theorized construct, may interrelate and affect female students' physics identity differently depending on the context. Context in this study refers to two different experiential levels in college. The constructs examined include performance/competence, recognition, and interest, as well as sense of belonging. In particular, we used structural equation modeling to examine the effect that these constructs have on the physics identity of two groups of female physics undergraduates: first year students and senior year students. The results reveal that the relationship of the theorized constructs with physics identity vary between the two groups as well as compared to prior research with broad college student populations (not just physics majors). Unlike broad college student populations, for our sample of female physics undergraduates, interest did not have a direct effect on physics identity while sense of belonging was significant only for senior year students. These results exemplify the importance of examining context or different types of student experiences when studying disciplinary identity development rather than generalizing previous frameworks to all contexts.

10. The Intersection of Being Black and Being a Woman: Examining the Effect of Social Computing Relationships on Computer Science Career Choice

Ross, Monique, Hazari, Zahra, Sonnert, Gerhard, and Sadler, Philip
- Abstract
Computer science (CS) has been identified as one of the fastest-growing professions, with demand for CS professionals far outpacing the supply of CS graduates. The necessity for a trained CS workforce has compelled industry and academia to evaluate strategies for broadening participation in CS. The current literature in CS education emphasizes the importance of social relationships and supports for individuals from underrepresented groups. Unfortunately, this literature has largely been limited to either the exploration of issues of women or that of underrepresented racial/ethnic groups. These limited views generalize characteristics of specific underrepresented groups without considering intersections between these groups. This quantitative study (n = 3,206) addressed that shortcoming by leveraging inferential statistical methods to examine (i) the similarities and differences between the social CS-related experiences of Black women, Black men, and non-Black women in the United States; (ii) the relationship between these experiences and CS career choices; and (iii) the activities during which significant social experiences might occur. The results indicate that Black women's social experiences are often different from the experiences of both Black men and non-Black women. In particular, both Black men and non-Black women had more CS friends than Black women, whereas having these friends was more significant for the CS career choice for Black women. Introductions to CS in school, before college, were negatively related to career choice for all groups, whereas home support was positive for both Black women and men. This work suggests that considering intersectionality is important to understanding the needs of different individuals, as well as the importance of social supports for persistence in CS.

11. Developing a Computing Identity Framework: Understanding Computer Science and Information Technology Career Choice

Mahadeo, Jonathan, Hazari, Zahra, and Potvin, Geoff
- Abstract
This paper expands on knowledge of computing identity by building on what is known about prior identity models in science and mathematics education. The model theorizes three primary sub-constructs that contribute to the development of a computing identity: belief in one's performance/competence, interest, and recognition in computing. Drawing on data from a nationally representative survey of more than 1,700 college students at 22 colleges and universities, the study tested the alignment of the theorized model to the measures on the survey. Confirmatory Factor Analysis was used to validate whether the appropriate measures loaded on the three separate sub-constructs. Criterion-related validity was also established by testing whether the computing identity measures predicted the choice of a computer science career. The results reveal that a computing identity proxy based on the theorized measures was a highly significant predictor of students' computer science and information technology career choice (p < 0.0001). In addition, this work also established criterion-related validity by showing gender differences that had been found by prior work in computing. Finally, the theorized measures were found to be reliable and internally consistent. The educational understanding of computing identities may provide an important tool to help researchers and practitioners improve student persistence in computer science.

- Abstract
Several avenues are open to students who wish to study advanced science or mathematics in high school, which include Advanced Placement courses and teacher-designed courses unaffiliated with organized programs. We employ a retrospective cohort study of 4,691 nationally representative college students at 34 randomly selected, colleges and universities to examine the relationship between taking advanced high school courses and students' interest in pursuing a STEM career, while controlling for prior interests and experiences. We are able to distinguish between those students choosing to take an additional year in a science or math subject from those taking Advanced Placement (AP), which is most commonly taken as a second year course, but is increasingly taken as a first year course. We find that the number of years of a science or math subject taken in high school is associated with significant increases in STEM career interest, with results differing by subject. Taking AP courses in science or calculus appear to have no significant impact on STEM career interest over that of other advanced, non-AP courses. Taking calculus, a second year of chemistry, or one or two years of physics all predict large increases in STEM career interest. Additional years in biology and other subjects show no such relationship.

13. Early Informal STEM Experiences and STEM Identity: The Importance of Talking Science

Dou, Remy, Hazari, Zahra, Dabney, Katherine, Sonnert, Gerhard, and Sadler, Philip
- Abstract
In this paper, we examine the relationship between participants' childhood science, technology, engineering, and mathematics (STEM) related experiences, their STEM identity (i.e., seeing oneself as a STEM person), and their college career intentions. Whereas some evidence supports the importance of childhood (i.e., K-4) informal STEM education experiences, like participating in science camps, existing research does not adequately address their relationship to STEM career intention later in life. Grounding our work in identity research, we tested the predictive power of STEM identity on career intention (N = 15,847). We found that for every one-point higher on our STEM identity scale, participants' odds of choosing a STEM career in college increased by 85%. We then tested whether a variety of childhood informal experiences predicted participants' STEM identity. While controlling for home environment, gender, and other relevant factors, only talking with friends and family about science, and consuming science and science-fiction media (i.e., books and television) were predictive of STEM identity in college.

- Abstract
Sexual harassment occurs more frequently in male-dominated fields and physics is a more male-dominated field than most other science, technology, engineering, and mathematics (STEM) fields. Thus, it is important to examine the occurrence and impact of sexual harassment on women in physics. A survey of undergraduate women, who attended a conference for undergraduate women in physics, revealed that approximately three quarters (74.3%; 338/455 ) of survey respondents experienced at least one type of sexual harassment. This sample was recruited from a large fraction of undergraduate women in physics in the United States. We find that certain types of sexual harassment predict a negative sense of belonging and exacerbate the imposter phenomenon. The types of sexual harassment that predict these outcomes, both forms of gender harassment, while seemingly less severe types of harassment, have been found to have substantially negative personal and professional consequences. These findings are important since prior work has found that sense of belonging and the imposter phenomenon are related to students' persistence in STEM fields. Our results have implications for understanding and improving persistence in physics by informing the community about the occurrence of sexual harassment and its effects so that we can begin to work towards reducing its occurrence and mitigating its effects.

15. Impact of Out-of-Class Science and Engineering Activities on Physics Identity and Career Intentions

Lock, Robynne M., Hazari, Zahra, and Potvin, Geoff
- Abstract
The number of physics bachelor's degrees that are awarded in the United States annually is small compared to most other science, technology, engineering, and mathematics fields, and only about one-fifth of these degrees are awarded to women. Understanding the influence of students' science and engineering experiences on career choices is critical in order to improve future efforts to increase the number of physics majors and the participation of women. In this work, we use a physics identity framework to examine the impact of out-of-class science and engineering activities on three identity dimensions and the relationship between these dimensions and physics career choice. Through structural equation modeling of survey data from 5541 college students, we find that out-of-class science and engineering activities have the largest influence on physics performance/competence beliefs, but the association of performance/competence beliefs to overall physics identity and physics career choice is primarily mediated through recognition beliefs and physics interests. Furthermore, out-of-class science and engineering activities have a larger effect on recognition beliefs for men than for women, which is a challenging finding in light of the fact that recognition beliefs are the most influential identity dimension for women. The results of this work begin to highlight the need for out-of-class science and engineering activities that focus on not only enhancing students' performance/competence beliefs but also students' interests, particularly those students not previously interested, and women's recognition beliefs with respect to physics.

16. High School Experiences and Climate Change Beliefs of First Year College Students in the United States

Shealy, Tripp, Klotz, Leidy, Godwin, Allison, Hazari, Zahra, Potvin, Geoff, Barclay, Nicole, and Cribbs, Jennifer
- Abstract
Climate change has not been well understood by high school students in the US and the topic is often connected to misconceptions, which is especially damaging since accurate understandings of the concepts are strongly predictive of intent to do something about it. We use data from a national (US) survey of first year college students to identify high school experiences which correlate with the belief that climate change is caused by human activities. In-class coverage of climate change is less predictive of belief than time spent on science homework or science-themed extracurricular activities. These correlations suggest that simply covering climate change in class may not necessarily lead to greater belief in the scientific consensus. While deeper understanding is a worthy goal, the results indicate that, when it comes to high school science education, social factors such as the process and culture of education are also important for belief in climate change. These finding aligns with previous research about college students, which suggest student activities are more strongly correlated with student viewpoints than professor beliefs. Given the potential for curricula to become politicized these finding suggests an alternative route to achieve climate change education goals.

Schwartz, Marc S., Hazari, Zahra, and Sadler, Philip M.
- Abstract
Interview data from secondary and postsecondary science instructors explored their in-depth views on preparing students for college science. Professors expressed a high level of consensus concerning two factors: general student skills and mathematics preparation. Teachers, who expressed lower levels of consensus, did agree on the importance of mathematics, but also highlighted a variety of factors that promote active pedagogy in the classroom as well as the importance of technology, textbooks, other materials, and assessments. Given this divergence, the authors explored the research supporting the value of these factors as well as highlighted possible strategies for narrowing the gap. (Contains 5 figures and 3 tables.)

- Abstract
Given the historic and continued underrepresentation of women in physics, it is important to understand the role that high school physics might play in attracting female students to physics careers. Drawing on data from over 900 female undergraduates in physics, we examine when these women became interested in physics careers and different sources of recognition (important for physics identity development) that may have affected their choices at certain time points. The results provide optimism since many of these female students, even those not previously intending science careers, began to intend physics careers in high school and recognition from high school physics teachers had a significant effect on predicting these intentions.

- Abstract
Using data from the first National study on high school preparation for college calculus success, the Factors Influencing College Success in Mathematics (FICSMath) project, this article connects student high school instructional experiences to college calculus performance. The findings reported here reveal that students were better prepared for college calculus success by high school instructional experiences that emphasized mathematical definitions, vocabulary, reasoning, functions, and hands-on activities. These findings serve to inform high school mathematics teachers about promising instructional practices. They can also inform teacher education programs about how to better prepare secondary mathematics educators to discuss conceptual understanding on the widely used Educative Teacher Performance Assessment (edTPA).

Godwin, Allison, Potvin, Geoff, Hazari, Zahra, and Lock, Robynne
- Abstract
Background: Prior to college, many students have no experience with engineering, but some ultimately choose an engineering career. Women choose engineering at lower rates than men. This article uses critical engineering agency (CEA) to understand first-year students' attitudes and self-beliefs to predict the choice of an engineering career. Purpose/Hypothesis: We investigated how first-year students' math and physics identities and students' beliefs about the ability of science to improve the world predict choice of engineering as a career and whether these beliefs differ by gender. Design/Method: The data were from the Sustainability and Gender in Engineering survey distributed during fall 2011 (N = 6,772). Structural equation modeling was used to understand first-year students' affective beliefs for predicting engineering career choice. Results: Math and physics identities are important for predicting engineering choice at the beginning of college. Recognition from others and interest in a subject are positive predictors of physics and math identities. Students' performance/competence beliefs alone are negative predictors of engineering career choice but are mediated by interest and recognition from others. Student identities and agency beliefs are significant predictors of engineering career choice, explaining 20% of the variance. We also found gender differences in students' math and physics identities and agency beliefs. Conclusions: This article emphasizes the importance of students' recognition beliefs and the importance of agency beliefs for women in predicting engineering career choice.

21. Student Evaluations of Physics Teachers: On the Stability and Persistence of Gender Bias
- Author

Potvin, Geoff and Hazari, Zahra
- Abstract
There is a long history of research which confounds the simple interpretation that evaluations in an educational context are purely measures of competency. One such issue is that of gender bias in student evaluations of their teachers. In our prior work, we found that male students underrated female high school teachers in biology and chemistry while all students underrated female high school teachers in physics. In the current work, we independently checked and extended this earlier work to examine the effect of physics identity on student evaluations and gender bias. Employing multiple regression on survey data from a representative sample of 6772 college students across the U.S., attending both 2-year and 4-year post-secondary institutions (including STEM and non-STEM majors), we find the core physics effect is unchanged despite a gap between studies of nearly 10 years. Namely, both male and female students underrate their female high school physics teachers, even after controlling for physics grades and classroom experiences. Our new focus on physics identity reveals that students with a strong physics identity show a larger gender bias in favor of male teachers than those with less of a physics identity. These results may help to explain how structures that privilege certain groups and marginalize others are prevalent amongst the youngest members of a defined physics community and may serve to uphold the status quo as these young members traverse to higher levels of physics community membership. Furthermore, biased evaluative feedback structures may be one of the propagators of women's lower competency beliefs in physics, a result that has been found by many prior studies.

22. Discussing Underrepresentation as a Means to Facilitating Female Students' Physics Identity Development

Lock, Robynne M. and Hazari, Zahra
- Abstract
Despite the fact that approximately half of high school physics students are female, only 21% of physics bachelor's degrees are awarded to women. In a previous study, drawn from a national survey of college students in introductory English courses, five factors commonly proposed to positively impact female students' choice of a physical science career were tested using multivariate matching methods. The only factor found to have a positive effect was the explicit discussion of the underrepresentation of women in physics. In order to explore this further, a case study of the classes of one teacher reported to discuss the underrepresentation of women was conducted. Two classroom underrepresentation discussions were recorded, students and teacher were interviewed, and relevant student work was collected. Analyzing the case study data using a figured worlds framework, we found that discussing the underrepresentation of women in science explicitly creates an opportunity for students' figured worlds of professional and school science to change, and facilitates challenging their own implicit assumptions about how the world functions. Subsequently, the norms in students' figured worlds may change or become less rigid allowing for a new openness to physics identity development amongst female students.

23. Establishing an Explanatory Model for Mathematics Identity

Cribbs, Jennifer D., Hazari, Zahra, and Sonnert, Gerhard
- Abstract
This article empirically tests a previously developed theoretical framework for mathematics identity based on students' beliefs. The study employs data from more than 9,000 college calculus students across the United States to build a robust structural equation model. While it is generally thought that students' beliefs about their own competence in mathematics directly impact their identity as a "math person," findings indicate that students' self-perceptions related to competence and performance have an "indirect" effect on their mathematics identity, primarily by association with students' interest and external recognition in mathematics. Thus, the model indicates that students' competence and performance beliefs are not sufficient for their mathematics identity development, and it highlights the roles of interest and recognition.

- Abstract
Background: Sustainability is increasingly a vital consideration for engineers. Improved understanding of how attention to sustainability influences student major and career choice could inform efforts to broaden participation in engineering. Purpose: Two related questions guided our research. How do career outcome expectations related to sustainability predict the choice of an engineering career? Which broader sustainability-related outcomes do students perceive as related to engineering? To address both questions, we compared effects for engineering and nonengineering students while controlling for various confounding variables. Design/Method: We conducted a survey to collect responses about sustainability and other variables of interest from a national sample of college students in introductory English classes. Data were analyzed using descriptive statistics and correlational analysis. Results: Students who hope to address certain sustainability issues such as energy, climate change, environmental degradation, and water supply are more likely to pursue engineering. Those who hope to address other sustainability issues such as opportunities for women and minorities, poverty, and disease are less likely to do so. Students hoping to address sustainability-related outcome expectations with obvious human relevance are less likely to pursue engineering. Yet those students who perceive "improving quality of life" and "saving lives" as associated with engineering are more likely to pursue the profession. Conclusions: Our results suggest that showing students the connection between certain sustainability issues and engineering careers could help those striving to increase and diversify participation in engineering. A broader range of engineers would likely bring new ideas and ways of thinking to engineering for sustainability.

- Abstract
This study explores students' self-perceptions across science subjects (biology, chemistry, and physics) by gender and underrepresented minority group membership. The data are drawn from the Persistence Research in Science and Engineering (PRiSE) project, which surveyed 7,505 students (enrolled in college English courses required for all majors) from 40 colleges and universities across the United States about their backgrounds, high school science experiences, and science attitudes. We compared the responses for three focal items on the PRiSE survey that asked students: "Do you see yourself as a biology/chemistry/physics person?" The results indicate that students' overall self-perceptions toward science are less than ideal. For many students in college, even those pursuing science-related careers, frequencies fell well below the midpoint of the scale. Consistent with other research, females had significantly lower self-perceptions toward physics, and Hispanic females tended to be the most disempowered in their views of themselves with respect to science.

- Abstract
There are many hypotheses regarding factors that may encourage female students to pursue careers in the physical sciences. Using multivariate matching methods on national data drawn from the Persistence Research in Science and Engineering (PRiSE) project ("n" = 7505), we test the following five commonly held beliefs regarding what factors might impact females' physical science career interest: (i) having a single-sex physics class, (ii) having a female physics teacher, (iii) having female scientist guest speakers in physics class, (iv) discussing the work of female scientists in physics class, and (v) discussing the underrepresentation of women in physics class. The effect of these experiences on physical science career interest is compared for female students who are matched on several factors, including prior science interests, prior mathematics interests, grades in science, grades in mathematics, and years of enrollment in high school physics. No significant effects are found for single-sex classes, female teachers, female scientist guest speakers, and discussing the work of female scientists. However, discussions about women's underrepresentation have a significant positive effect. (Contains 3 tables and 1 figure.)

- Abstract
Many students enrolled in university physics have little interest in the subject matter, a trend more pronounced in females. This study assesses students' conceptual understanding and interest during the electrochemistry unit of a physics course for nonphysics majors that was revised in light of consistently low ratings from its students. The intervention, designed to improve the tutorials in a large lecture-based physics course, improved interest in the topic for which the new tutorials were implemented. However, no effect was seen for conceptual understanding, and the gender gaps persisted. (Contains 2 tables.)

- Abstract
What motivates individuals to embark on graduate careers in physics and chemistry and how could these motivations impact future productivity? This study examines gender differences in such motivations and their ability to predict select future success outcomes (publications and grant funding) for physical scientists. The data were obtained as part of Project Crossover, a national study of physicists and chemists. Overall, motivations for males and females were similar. Regression results indicate that individuals who chose a graduate career in the physical sciences primarily because they enjoyed thinking about science or were encouraged by significant others were more productive in terms of primary/first-author publications and generation of grant funding than those who were motivated by factors such as academic performance or desire to impact society.

- Abstract
Spurred by concerns about an inadequately sized science, technology, engineering, and mathematics (STEM) workforce, there has been a growing interest in out-of-school time (OST) science activities as a means to foster STEM career interest. This study examines the association between OST science activities and STEM career interest in university through a logistic regression model and the calculation of prototypical odds ratios. The analysis addresses two main research questions: What is the correlation among different forms of OST activities? And, controlling for student demographic and background variables, what specific forms of OST activities are associated with STEM career interest in university? The study uses data from the "Persistence Research in Science and Engineering" survey (n = 6882), which employs a nationally representative sample of university students enrolled in introductory English courses. Results indicate that students' participation in OST activities, as well as their middle school interest in science and mathematics and their gender, plays a significant role in university career interest in STEM. Conclusions suggest that making OST clubs and competitions and the inclusion of non-fiction and science fiction within English Language Arts programmes may be beneficial to the development of students in STEM careers. Limitations include the paucity of research examining which students participate in these activities and what specific features or characteristics benefit them.

30. Connecting High School Physics Experiences, Outcome Expectations, Physics Identity, and Physics Career Choice: A Gender Study

- Abstract
This study explores how students' physics identities are shaped by their experiences in high school physics classes and by their career outcome expectations. The theoretical framework focuses on physics identity and includes the dimensions of student performance, competence, recognition by others, and interest. Drawing data from the Persistence Research in Science and Engineering (PRiSE) project, which surveyed college English students nationally about their backgrounds, high school science experiences, and science attitudes, the study uses multiple regression to examine the responses of 3,829 students from 34 randomly selected US colleges/universities. Confirming the salience of the identity dimension for young persons' occupational plans, the measure for students' physics identity used in this study was found to strongly predict their intended choice of a physics career. Physics identity, in turn, was found to correlate positively with a desire for an intrinsically fulfilling career and negatively with a desire for personal/family time and opportunities to work with others. Physics identity was also positively predicted by several high school physics characteristics/experiences such as a focus on conceptual understanding, real-world/contextual connections, students answering questions or making comments, students teaching classmates, and having an encouraging teacher. Even though equally beneficial for both genders, females reported experiencing a conceptual focus and real-world/contextual connections less frequently. The explicit discussion of under-representation of women in science was positively related to physics identity for female students but had no impact for male students. Surprisingly, several experiences that were hypothesized to be important for females' physics identity were found to be non-significant including having female scientist guest speakers, discussion of women scientists' work, and the frequency of group work. This study exemplifies a useful theoretical framework based on identity, which can be employed to further examine persistence in science, and illustrates possible avenues for change in high school physics teaching.

31. For the Love of Learning Science: Connecting Learning Orientation and Career Productivity in Physics and Chemistry

- Abstract
An individual's motivational orientation serves as a drive to action and can influence their career success. This study examines how goal orientation toward the pursuit of a graduate degree in physics and chemistry influences later success outcomes of practicing physicists and chemists. Two main categories of goal orientation are examined in this paper: "performance" orientation or motivation to demonstrate one's ability or performance to others, and "learning" orientation or motivation through the desire to learn about a topic. The data were obtained as part of Project Crossover, a mixed-methods study which focused on studying the transition from graduate student to scientist in the physical sciences and included a survey of members of two national professional physical science organizations. Using regression analysis on data from 2353 physicists and chemists, results indicate that physicists and chemists who reported a "learning" orientation as their motivation for going to graduate school were more productive, in terms of total career primary and/or first-author publications and grant funding, than those reporting a "performance" orientation. Furthermore, given equal salary, "learning"-oriented individuals produced more primary and/or first-author publications than their nonlearning oriented counterparts.

32. Gender Differences in the High School and Affective Experiences of Introductory College Physics Students

- Abstract
The disparity in persistence between males and females studying physics has been a topic of concern to physics educators for decades. Overall, while female students perform as well as or better than male students, they continue to lag considerably in terms of persistence. The most significant drop in females studying physics occurs between high school and college. Since most female physicists report that they became attracted to physics and decided to study it further while in high school, according to the International Study of Women in Physics, it is problematic that high school is also the stage at which females begin to opt out at much higher rates than males. Although half of the students taking one year of physics in high school are female, females are less likely than males to take a second or Advanced Placement (AP) physics course. In addition, the percentage of females taking the first physics course in college usually falls between 30% and 40%. In other words, although you may see gender parity in a first high school physics course, this parity does not usually persist to the next level of physics course. In addition, even if there is parity in a high school physics course, it does not mean that males and females experience the course in the same way. It is this difference in experience that may help to explain the drop in persistence of females.

33. Gender Differences in Introductory University Physics Performance: The Influence of High School Physics Preparation and Affective Factors

- Abstract
The attrition of females studying physics after high school is a growing concern to the science education community. Most undergraduate science programs require introductory physics coursework. Thus, success in introductory physics is usually necessary for students to progress to higher levels of science study. Success also influences attitudes; if females are well prepared, feel confident, and do well in introductory physics, they may be inclined to study physics further. This quantitative study using a hierarchical linear model focused on determining factors from high school physics preparation (content, pedagogy, and assessment) and the affective domain that predicted female and male performance in introductory university physics. The data analyzed came from 1973 introductory university physics surveys that included variables used as controls for student demographic and academic background characteristics. The results highlight high school physics and affective experiences that differentially predicted female and male performance. These experiences include learning requirements, long-written problems, cumulative tests/quizzes, father's encouragement, and family's belief that science leads to a better career. There were also factors that had a similar effect on female and male performance among which mathematics preparation was the overall strongest predictor of university physics performance.

Previous research suggests strong connections between students' mathematics background and their persistence in engineering career aspirations. This study expands on that research by examining how mathematics identity impacts the choice of engineering careers for male and female students. Data used in this study were drawn from the Factors Influencing College Success in Mathematics project, a nationally-representative survey garnering responses from 10,437 college calculus students. Results from an exploratory factor analysis validated the mathematics identity framework proposed. Additionally, results from a logistic regression indicate that mathematics interest and recognition in mathematics significantly predict the choice of an engineering career, even after controlling for SAT/ACT mathematics scores and demographic background, such as parental education. Moreover, the interaction between recognition in mathematics and gender is also significant and indicates that being recognized in mathematics has a stronger positive impact on the choice of an engineering career for females than for males.

This retrospective cohort study characterizes how interest in science, technology, engineering, mathematics (STEM) careers changes during high school for more than 6,000 students in a representative national sample of 34 two- and four-year colleges taking mandatory college English courses. Overall, large gender differences in career plans were found, with males showing far more interest particularly in engineering, whereas females were more attracted to careers in health and medicine during their high school years. The key factor predicting STEM career interest at the end of high school was interest at the start of high school. There was an additional effect of gender, indicating both a lower retention of STEM career interest among females and a greater difficulty in attracting females to STEM fields during high school. During the high school years, the percentage of males interested in a STEM career remained stable (from 39.5 to 39.7), whereas for females it declined from 15.7 to 12.7. The students' initial specific (disciplinary) career interests were found to influence the stability of their interest in a STEM career, with those interested in physics careers at the start of high school having the highest retention in STEM. © 2012 Wiley Periodicals, Inc.

Higher education institutions collect information about students for countless reasons: analyzing demographics, evaluating programs, recruiting top students, and measuring learning outcomes, among others. As sustainability concerns are an increasingly central issue in many students' college selection process (Grummon 2008), there is a need to better understand students who exhibit prosustainability attitudes and behaviors-those students most interested in sustainability (MIS).
