Methods to estimate the causal effects of interventions are increasingly used in clinical medicine, public policy and social science. Using observational data, researchers can obtain causal treatment effect estimates without the ethical risks and time constraints that typically burden randomized experiments. The three studies in this dissertation…

Disproportionate rates of behavioral problem reporting and consequences for African American males have occurred for decades. With the consequences surrounding problem behaviors typically removing the student from the classroom, whether to the principal's office or for an in-school or out-of-school suspension, time spent in the classroom for…

This quantitative study examines the outcomes of the Pre-Matriculation program at the University of Kansas Medical Center's School of Medicine, a pipeline initiative designed to equip students from historically underrepresented groups in medicine (HURM) with the skills and knowledge necessary for success in medical school. A student is considered…

U.S. school achievement has been the subject of much discussion. In the case of science, technology, engineering, arts, and mathematics (STEAM), the national underperformance across the country, as well as the underrepresentation of minorities are key issues (Anderson et al., 2023; Handelsman & Smith, 2016; National Research Council, 2015; The…

This qualitative study aims to explore the lived experiences of Black principals, focusing on the intersectionality of race and educational leadership. Through purposive sampling, the study delves into the challenges encountered by Black principals, including limited preparation provided by principal programs, racial biases undermining their…

Disproportionality in special education is a complex issue adversely impacting African-American students. African-American students experience disproportionality in referral to special education and identification with a disability, removing them from the general education setting and resulting in denial of access and socialization with their…

Leadership, teachers, and parents have observed significantly disproportionate discipline of African American students at urban elementary schools located in Ohio, despite the implementation of positive behavior intervention supports (PBIS). This basic qualitative study explored teacher perceptions of the overrepresentation of disciplinary actions…

Zero-tolerance in school disciplinary procedures impacts or contributes to the nationwide school-to-prison pipeline (STPP). According to the American Bar, school prison incarceration rates in the United States (U.S.) have been correlated to the excessive practices of school disciplinary policies. The U.S. incarcerates more citizens than any other…

Marginalized students often feel a greater sense of detachment from their schools in comparison to non-marginalized peers (Bottiani et al., 2017). Mentorship programs provide positive experiences that enhance adolescents' social, behavioral, and academic development. These programs help disconnected students establish a stronger connection within…

The purpose of this mixed-methods study was to explore the impact of informal STEM education on underrepresented middle school girls. The study took place within the context of the EUREKA! summer program, a collaboration between Drexel University's Department of Civil, Architectural, and Environmental Engineering and Girls Inc. of Philadelphia and…

Science, Technology, Engineering, and Mathematics (STEM) areas are one of the fastest-growing majors in the nation, engineering, is projected to add the second largest number of new jobs from 2016 to 2026 with 140,000 new jobs (Torpey, 2018). Unfortunately, there is a disparity between enrollment and graduation rates (Chen, 2015; Lucas &…

Severe inequities for underrepresented student groups (URGs) in Science, Technology, Engineering, Mathematics, and Medicine (STEMM) fields has remained a topic of national concern for several decades. Research has demonstrated the efficacy of STEMM intervention programs (SIPs) in addressing disparate STEMM outcomes. However, there is a dearth of…

Black women undergraduates are represented in low numbers in science, technology, engineering, and mathematics (STEM) fields. Research studies have lacked data outlining the compounding effects of the intersectional, gendered, and racialized experiences they often face in their programs of study. Participation in kinship networks may be a critical…

African American males receive a disproportionate number of referrals that result in punitive and exclusionary consequences. These referrals are often more subjective and include reasons such as disrupting class, disrespect, and refusal to obey. In- and out-of-school suspensions lead to a loss of instructional time for students, as well as a…

Higher education has long recognized women's numerous challenges in undergraduate engineering programs. Several factors contribute to this lack of belonging, including a lack of diversity among student populations, microaggressions, prejudices, and traditions still rooted in male customs. An overlooked factor that may help foster a sense of…
