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 IndividualityandEquality 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.more » « less

Engineering educators in many contexts are increasingly being called to contribute to equity. The focus of our CAREER project is to investigate the ways in which engineering faculty, staff and administrators think about the cause of gender- and race-based minoritization in engineering. Specifically, we investigate the beliefs they express about why women and people of color remain minoritized in engineering and how they arrive at those beliefs. Long term goals of the work include designing evidence-based professional development that can support faculty at any stage in their development as change agents for equity in engineering. The overarching project design includes a series of four one-on-one interviews with participants. The first two interviews are focused on their beliefs about gender- and race-based minoritization, respectively. The third interview will explore their narrative, and the fourth interview (or some type of interaction) will be designed based on how the project evolves and what we learn. We are currently in the second year of the project. To start, our research team used crowdsourcing as a method of recruiting our participants. We asked students to identify engineering educators that they considered to be inclusive based on their lived experience. We oversampled for students from minoritized groups (non-male, non-white). We also allowed those nominated by students to refer to any peers that they felt were inclusive. This resulted in the following participant pool with at least one majority identity (race or gender): 11 white men, 11 white women, and 5 men of color. After piloting our initial interview protocol, we completed gender beliefs interviews with all 27 participants during the 2020-2021 academic year. We had the interviews transcribed, and members of our research checked them for accuracy and de-identified them. The clean transcripts were then sent back to the participants for review. We began data condensation by generating a summary sheet for each participant, which includes the main concepts captured in each section of their gender beliefs interview. We are currently (2021-2022) conducting race beliefs interviews with those same participants. We published the results of piloting the use of our methodological framework, Thinking as Argument (TaA) in the 2021 ASEE proceedings. In short, we believe the framework shows promise for studying beliefs at a deeper level by inviting participants to work through the types of evidence they draw on to commit to their beliefs about the cause of minoritization in engineering. In this paper, we offer some insights that are emerging at this early stage of the project: Different participants draw on diverse ways of knowing to commit to their beliefs, including lived experience and scholarship. These ways of knowing seem potentially related to their own identities. For example, several participants who identify as men of color leverage their own experiences with racism to explain the cause of sexism. This insight has given us pause on the ways in which our framework, TaA, privileges academic or argumentative ways of knowing. We are gaining awareness of the incredible complexity that exists within trying to characterize or evaluate someone's contributions to equity as they relate to their ways of thinking. This finding has given us a pause about the ways in which we, as researchers, assign value to ways of being or acting. At this current stage, we are exploring further by engaging ourselves in reflection of other ways in which beliefs in this context are formed and we are inviting others to do the same. Future work will include ongoing analysis and sensemaking. With the race beliefs completed, we will be able to use data display techniques to explore any patterns between the participants’ beliefs and positionalities. We look forward to honing our protocol for the narrative interviews and are soliciting feedback in terms of how to use the fourth and final interaction of the project in a more participatory way to encourage and give back to our participants.more » « less

Education researchers often compare performance across race and gender on research-based assessments of physics knowledge to investigate the impacts of racism and sexism on physics student learning. These investigations' claims rely on research-based assessments providing reliable, unbiased measures of student knowledge across social identity groups. We used classical test theory and differential item functioning (DIF) analysis to examine whether the items on the Force Concept Inventory (FCI) provided unbiased data across social identifiers for race, gender, and their intersections. The data was accessed through the Learning About STEM Student Outcomes platform and included responses from 4,848 students posttests in 152 calculus-based introductory physics courses from 16 institutions. The results indicated that the majority of items (22) on the FCI were biased towards a group. These results point to the need for instrument validation to account for item bias and the identification or development of fair research-based assessments.more » « less

Is there a relationship between mathematics ability beliefs and STEM degrees? Fields such as physics, engineering, mathematics, and computer science (PEMC) are thought to require talent or brilliance. However, the potential effects of difficulty perceptions on students’ participation in STEM have yet to be examined using a gender and race/ethnicity intersectional lens. Using nationally representative U.S. longitudinal data, we measure gender and racial/ethnic variation in secondary students’ orientation towards mathematics difficulty. We observed nuanced relationships between mathematics difficulty orientation, gender, race/ethnicity, and PEMC major and degree outcomes. In secondary school, the gap between boys’ and girls’ mathematics difficulty orientations were wider than gaps between White and non-White students. Mathematics difficulty orientation was positively associated with both declaring majors and earning degrees in PEMC. This relationship varied more strongly based on gender than race/ethnicity. Notably, Black women show higher gains in predicted probability to declare a mathematics-intensive major as compared to all other women, given their mathematics difficulty orientations. This study’s findings show that both gender and racial/ethnic identities may influence the relationship between mathematics difficulty orientation and postsecondary STEM outcomes.more » « less
