Existing research consistently indicates that Black girls are assigned disproportionately exclusionary disciplinary consequences such as, suspension and expulsion rates, surpassing their White counterparts and Black boys. According to the Report to Congressional Requesters, (United States Governmental Accountability Office, 2018), exclusionary…

Background: The underrepresentation of women in science, technology, engineering, and mathematics (STEM) remains a persistent international challenge with complex causes. This study draws on five complementary theoretical perspectives--theory of circumscription and compromise, situated expectancy-value theory, the internal/external frame of…

A complex web of factors can influence whether students participate in computer science (CS) during high school. In order to increase participation in CS for all students, there is a need to better understand who is currently participating and what factors might be hindering participation. This study utilized a large-scale, student-level dataset…

Graduation from high school is a commonly accepted measurement of academic achievement within the PK-12 education system. Failure to meet this academic milestone is well noted to result in unfavorable outcomes in the transition to, and throughout, adulthood; negatively impacting individuals' health and employment opportunities, while increasing…

First-generation college students (FGCS), nearly 50% of which identify as Hispanic, are an underserved population. The psychosociocultural theoretical framework posits that individual, environmental, and cultural factors contribute to the academic success of Hispanic students. This study examined the relationship between these factors (i.e.,…

This dissertation investigates whether dual credit students' academic performance in subsequent university courses is comparable to that of non-dual-credit students. The study uses data from a Midwest regional public university over a ten-year period and employs propensity score matching and proportional odds ordinal logistic regression to create…

High school is a critical period for science identity development. Teacher influences are important but under-researched. Teachers' growth-mindset practices may help students meet the growing challenges to their ability, achievement, and identity in science and have long-term influences, especially for underrepresented students. We explored U.S.…

Racial and ethnic achievement gaps contribute to the lack of underrepresented minorities in STEM-related careers. This research is grounded in the expectancy-value model of achievement motivation which posits that motivation is influenced by social-cognitive variables such as self-efficacy and beliefs about the usefulness or utility of the task.…

Discipline disproportionality is the overuse of exclusionary discipline, such as suspension and expulsion, on Black students in American schools. This study adds to the literature by examining how parental involvement affects racial disparities in disciplinary outcomes in in-school suspension and by theoretically analyzing how parents' social and…

My study seeks to explore the extent that select secondary and postsecondary indicators predict STEM student enrollment and persistence particularly for Hispanic students. Identifying postsecondary STEM success and college readiness indicators with special focus on malleable indicators that can assist educators, administrators, and policymakers in…

The Advanced Placement Computer Science Principles (APCSP) course was introduced in 2016 to address long-standing gender and racial/ethnic disparities in the United States among students taking Advanced Placement Computer Science (APCS) in high school, as well as among those who pursued computing majors in college. Although APCSP has drawn a more…

Women continue to be under-represented in science fields in Australia and internationally. Efforts to fix the 'leaky pipeline' producing this inequality are frustrated by declining enrolments in higher-level school science subjects. Researchers and policymakers need a better understanding of the factors which influence girls' decisions to take…

While demand for computer science and information technology skills grows, the proportion of women entering computer science (CS) fields has declined. One critical juncture is the transition from high school to college. In our study, we examined factors predicting college persistence in computer science- and technology-related majors from data…

This study examines the relationship between students' perceptions of teacher treatment, school suspensions, and school climate in three high schools in Central New York (N = 1,444). Students completed an anonymous questionnaire about their perceptions of school climate and school disciplinary practices. Results showed racial and ethnic…

This study examined the extent to which disparities in Black and White students' risks of receiving office discipline referrals (ODRs), and out-of-school suspensions (OSSs) were related to differences in implicit and explicit racial biases assessed at the community level. The sample consisted of discipline records for 1,354,010 students enrolled…
