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…

Supporting underrepresented students in STEM majors is critical for student retention. The Collegiate Science and Technology Program (CSTEP) grant has the purpose to build community among participants, help them feel connected, provide supportive programming, and retain them both in college and within STEM majors. This study used a mixed-methods…

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…

Purpose: While women earn an equal proportion of undergraduate degrees in biomedical engineering, there is a significant decline in female representation at the graduate and faculty levels. Prior studies suggest that an inclusive environment could increase female retention in engineering, and there has been increased interest in adding elements of…

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 &…

Gaps in advanced high school coursework by socioeconomic status and geography persist in the United States, even among students with the ability and access to succeed in them. Lack of information on course availability and inaccurate self-perceptions may contribute to these inequities. We report on a large-scale experiment designed to increase…

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…

Female teachers in Mathematics and Science often face persistent challenges related to limited content knowledge, low self-efficacy, and underrepresentation in STEM fields. These barriers hinder their professional growth and impact on the quality of STEM education. This study aimed at investigating the contribution of Continuous Professional…

African American (AA) male youth across the United States are often detained or committed to juvenile facilities at a higher rate than most population groups due to criminal or delinquent behavior. The research explored the risk and protective factors associated with delinquency for this population while bringing awareness to delinquency and vital…

Current childhood obesity treatment programs do not address medically underserved populations or settings where all members of an interdisciplinary team may not exist - either within one organization or within the community. In this paper, we describe the use of a community-academic partnership to iteratively adapt Epstein's Traffic Light Diet…

This study examines the impact of an alternative to suspension program on second semester office discipline referrals for participating students. The study compares students who completed the intervention program with those who would have qualified during the school year prior to the program being available at the school district. The study was…

The problem addressed in this study is the disproportionality in office discipline referrals (ODRs) for Black students at a Northeast Florida Middle School despite the implementation of School-wide Positive Behavioral Interventions and Supports (SWPBIS). The purpose of this qualitative case study was to understand middle school teachers'…

The gap in achievement and discipline between White and Black students is a significant problem in education across the nation. The objective of this study was to determine if the achievement gap increases once schools decrease suspension rates and offer alternatives to out-of-school suspension. The purpose of this study was to determine the…

The United States higher education system has developed strategies to prepare students for Science, Technology, Engineering, and Math (STEM) careers as the STEM labor market expands. One set of educational interventions, known as STEM Intervention Programs (SIPs), employs extracurricular activities to engage and retain STEM major students. These…
