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…

Background: STEM education providers increasingly use complex intervention models to redress persistent under-representation in STEM sectors. These intervention models require robust evaluation to determine their effectiveness. The study examines a complex, sustained intervention intended to build science capital in young people aged 11-15 over…

As postsecondary developmental education policy reforms are implemented, increased attention must be given to students with learning and attention disabilities. The purpose of this study was to bring these students into the conversation, by examining their representation in developmental education broadly, as well the effect of this intervention…

Gender imbalance in the technology sector is a long-standing issue. For several decades, Computer Science (CS) outreach activities have become an established strategy for encouraging girls to pursue courses and careers in the field of computing. However, it is not clear how impactful these initiatives are, or what elements make them valuable. A…

There is currently a lack of diversity in the discipline of statistics. In order to provide opportunities within the discipline of statistics to diverse groups, the present study presents a detailed description and evaluation of a one-credit workshop and mentoring program for undergraduate women interested in exploring opportunities within…

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…

Underrepresented minority (URM) faculty hold about 10% of tenured positions, despite URM comprising more than 30% of the United States population; thus, disparities remain in the recruitment, development, retention and promotion of diverse faculty in large part because of a lack of mentoring. Research suggests that mentoring from senior URM…
