The American Physical Society calls on its members to improve the diversity of physics by supporting an inclusive culture that encourages women and Black, Indigenous, and people of color to become physicists. Introductory physics courses provide opportunities for recruiting and retaining diverse students or enacting policies and cultural practices that disproportionately harm students from minoritized groups. Introductory calculus-based electricity and magnetism courses have received far less attention from researchers than introductory mechanics courses. To better understand the role introductory electricity and magnetism courses play in the lack of diversity in physics, we investigated the intersecting relationships between racism and sexism in inequities in student conceptual knowledge using a quantitative critical framework. The analyses used Bayesian hierarchical linear models to examine students' conceptual knowledge as measured by the Conceptual Survey of Electricity and Magnetism. The data came from the LASSO database and included 3,686 students from 83 calculus-based courses at 16 institutions. The model indicated society owed educational debts in conceptual knowledge due to racism, sexism, or both to Black, Hispanic, Asian, and White Hispanic students and White women. Of these groups, society owed the largest educational debts to Black students. The courses, of which almost all used collaborative instruction (81 of 83) supported by learning assistants (66 of 83), added to the educational debts owed to Black students, maintained the debts owed to Hispanic and White Hispanic students and White women, and mitigated the debts owed to Asian students.

Educational debts incurred by racism and sexism in students’ beliefs about physics
The American Physical Society calls on its members to improve the diversity of physics by sup- porting an inclusive culture that encourages women and people of color to become physicists. Becoming a physicist demands a set of beliefs about what it means to learn and do physics. Rather than physics courses and degree programs supporting students in developing these beliefs, evidence shows that physics education filters out students without sufficient beliefs. To better understand the role of beliefs in the lack of diversity in physics, we investigated the intersectional nature of race/racism and gender/sexism in inequities in student beliefs towards learning and doing physics using a critical quantitative intersectionality framework. The analyses used hierarchical linear models to examine students’ beliefs as measured by the Colorado learning attitudes about science survey. The data came from the LASSO database and included 1248 students in 29 calculus-based mechanics courses. Like prior studies, we found that beliefs either did not change or slightly decreased for most groups. Results identified large differences across intersecting race and gender groups. White students, particularly White men, tended to have more expert-like beliefs than any other group of students. Physics instruction must address these educational debts to move toward an inclusive culture supportive of diverse students and professionals.

Abstract We investigated the intersectional nature of race/racism and gender/sexism in broad scale inequities in physics student learning using a critical quantitative intersectionality. To provide transparency and create a nuanced picture of learning, we problematized the measurement of equity by using two competing operationalizations of equity:
Equity of Individuality andEquality of Learning . These two models led to conflicting conclusions. The analyses used hierarchical linear models to examine student's conceptual learning as measured by gains in scores on research‐based assessments administered as pretests and posttests. The data came from the Learning About STEM Student Outcomes' (LASSO) national database and included data from 13,857 students in 187 first‐semester college physics courses. Findings showed differences in student gains across gender and race. Large gender differences existed for White and Hispanic students but not for Asian, Black, and Pacific Islander students. The models predicted larger gains for students in collaborative learning than in lecture‐based courses. The Equity of Individuality operationalization indicated that collaborative instruction improved equity because all groups learned more with collaborative learning. The Equality of Learning operationalization indicated that collaborative instruction did not improve equity because differences between groups were unaffected. We discuss the implications of these mixed findings and identify areas for future research using critical quantitative perspectives in education research. -
https://peer.asee.org/27950 This paper presents results of work completed on our project, Intersectionality of Non-normative Identities in the Cultures of Engineering (InIce). The overarching focus of this project is on how students who hold non-normative identities position themselves, grow through their education, and navigate the cultures of engineering they experience in college. Our goal is to investigate ways to engage students who hold non-normative identities to become more active and lifelong participants in engineering disciplines. Our work is proceeding in three phases: 1) Identify, through a quantitative instrument, the attitudinal profiles of normative and non-normative students in engineering; 2) Characterize students’ normative and non-normative identities through in-depth interviews and analysis of differences between students with normative and non-normative identities in engineering; and 3) Drawing from our findings, develop a workshop and set of courses to incorporate diversity topics into engineering programs to enhance the culture of engineering to be more responsive towards, and inclusive of, a diverse range of student identities. We have completed the first phase of the project in which we quantitatively measured and characterized student groups with normative and non-normative identities in engineering. Our definitions of normative and non-normative for this project are developed through Topological Data Analysis (TDA) of a set of multi-institution survey data (n = 2916). TDA allows identification of groups without imposing a priori hypotheses on how the attitudes of students may group together (nor how they may distinguish between demographic groups). This approach allows the underlying structure of the data to emerge rather than imposing pre-defined definitions of normative attitudes or identities. Our TDA results revealed one group that contains a relatively large number of students (the “normative” group) and a total of seven other distinct, but relatively populated, groups (the “non-normative” groups). We have compiled a summary of the most salient attitudinal constructs in terms of characterizing and distinguishing between all these groups including: motivation (value, goal orientation, future time perspective), engineering and physics identities (performance/competence and recognition beliefs for each), personality traits (neuroticism, extraversion, belongingness) and grit (consistency of interest). We are currently in Phase 2 of our study in which we are conducting a series of qualitative, longitudinal interviews with students selected from normative and non-normative groups to understand how they navigate their engineering experiences and define their educational trajectories over the first two years of college. This data will be deductively analyzed based on our existing attitudinal frameworks as well as inductively coded for emerging themes on how students feel belongingness within engineering culture. This project promises to move traditional measures of demographic data beyond socially constructed perceptions of others and allows for the representation of student diversity from the perspective of each participant. This more accurate reflection of diversity provides novel insight into the experiences of students who might otherwise be ignored or unjustifiably lumped in with other students with whom they share some demographic indicator and how residing at the intersection of multiple measures of diversity can influence students’ experiences in engineering culture.more » « less

Giving a voice to marginalized groups and understanding the double bind is critical, especially after the Charlotte, VA protests and the white supremacist discourse that has pervaded our country. The result of the discourse, more subtle beliefs about white superiority and institutional barriers is an overrepresentation of women of color (WOC) in the leaky STEM pipeline and thus the loss of their presence and expertise. The absence of WOC hinders knowledge production and innovation that is essential for societal advancements and scientific discovery. The “chilly climate” is often cited as an explanation for the loss of WOC from STEM. However, interactions that allow the “chilly climate” to persist have yet to be characterized. This lack of understanding can inhibit the professional engineering identity construction of WOC. Additionally, engineering education research typically focuses on a single identity dimension such as gender or socio-economic status. These studies connect an identity dimension to student outcomes and few studies clarify how the identity is situated within the social context of the engineering culture. Consequently, a need exist to examine how the engineering culture impacts multiple components of identity and intersecting identities of WOC. To address this gap, our study illuminates the intersections of identity of WOC and how they perceive the double bind of race and gender within the context of their engineering education. The data reported here are a part of a larger, sequential mixed-methods study (N=276) of undergraduate female engineering students at a large Midwestern research university. This project applies the framework of intersectionality with the following scales: Engineering Identity, Ethnic Identity, Womanist Identity, Microaggressions, and Depression. We use intersectionality to investigate the interaction between intersecting social identities and educational conditions. We introduce the Womanist Identity Attitude scale to engineering education research, which provides an efficient way to understand gender, racial, and intersecting identity development of WOC. We utilize the microaggressions scale, in order to develop quantitative measures of gender-racial discrimination in STEM and compare to previous research. We also included the Patient Health Questionnaire (PHQ-9), an instrument for measuring depression, to assess health outcomes of respondents’ experiences of gender-racial microaggressions. Our three emergent findings suggest instrument accuracy and provide insight into the identity and depression subscales. Factor analysis established a basis to refine our quantitative survey instruments, and indicated that 23 items could offer greater accuracy than the original 54 items instrument. Second, the majority of participants report a high level of identification with engineering. This result rebuffs the long-held stereotypes that females are less interested in engineering. Third, a significant portion of female respondents self-reported PHQ-9 scores in the 15-19 range, which corresponds with a “major depression, moderately severe” provisional diagnosis, the second-highest in severity in the PHQ-9 provisional diagnosis scale. These elevated levels of depression correlated significantly to frequent instances of microaggressions. These preliminary findings are providing never-before seen insight into the experiences of WOC in engineering. Our results suggest a path to accurately describe the experiences of WOC in engineering, while revealing options for improving inclusion efforts.more » « less
