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…

The purpose of this study was to examine the impact of a behavioral based intervention program on minority student behavior. The Breakfast Club was an intervention created with the goal of improving the negative behavior of minority adolescent students. The participants in this study were minority, high school students who displayed frequent…

Colleges across the United States have shown a commitment to advancing diversity in the STEM fields by creating programs aimed at improving outcomes of women and/or racially and ethnically minoritized students. However, most existing literature focuses on the successes of singular college programs rather than comparing these STEM interventions…

Background: Substance use in minoritized youth is associated with negative long-term health and life outcomes. The present study explores perspectives of school stakeholders at urban minority-serving schools regarding integration of an evidence-based intervention, screening, brief intervention, and referral to treatment (SBIRT) into existing…

Due to the impacts of overrepresentation of historically marginalized middle school student suspensions on the prison pipeline, there is urgency in addressing disproportionality in suspensions in school districts nationwide. Although Multi-Tiered Systems of Support (MTSS) and Positive Behavior Interventions and Supports (PBIS) models have shown an…

Certain introductory engineering courses have been termed gateway courses, due to high failure rates resulting in many students leaving engineering altogether. In one such course, thermodynamics, instructors intentionally formed peer-led study groups (PLSGs) with an undergraduate teaching aide (UGTA) playing a supportive facilitator role instead…

"Social Belonging" interventions for college students aim to reduce the impacts of negative stereotypes that may burden students in underrepresented groups and affect their persistence in college. This What Works Clearinghouse (WWC) report, part of the WWC's Supporting Postsecondary Success topic area, explores the effects 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…

Behavior specific praise (BSP) is widely regarded as an evidence-based classroom management strategy, with decades of research supporting its use. However, relatively few studies have examined the effect of BSP as a "targeted" intervention strategy, particularly for traditionally underrepresented students. The present study evaluated the…

This research aimed to (1) develop interventions for enhancing executive functions (EFs) and (2) examine the effects of participatory EF enhancement in ethnic preschool children. The researchers sampled 197 preschool teachers and parents from 7 Border Patrol Police Schools in northern Thailand using simple random sampling. The research instruments…

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…

Schools in the United States are becoming more diverse with respect to race, ethnicity, gender, and sexuality, but many minority students experience disconnection from school for a variety of reasons. Longstanding research on the jigsaw method suggests that it has been an effective intervention for increasing interdependence among students and…

This research aimed to test Difference-Education Intervention (DEI) to determine the impact of this intervention on first-generation students' sense of belonging, mindset, and hope in Hispanic Serving Institutions. Social Learning Theory was used to understand that individuals must internalize what is learned and perceived socially, as learning…

Early intervention is a method institutions use to identify and support students who are having academic difficulty and might be designated as "at-risk", or more likely to leave an institution (Villano et al., 2018). Institutions often adopt early alert systems to support early intervention efforts and student retention (Barefoot et al.,…
