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…

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…

Disparities in gifted representation across demographic subgroups represents a large and persistent challenge in U.S. public schools. In this paper, we measure the impacts of a school-wide curricular intervention designed to address such disparities. We implemented Nurturing for a Bright Tomorrow (NBT) as a cluster randomized trial across…

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…

The purpose of this study was to implement a redesign of developmental education at Delaware Technical Community College and to evaluate its effectiveness in improving overall First Time Ever in College (FTEIC) student success through gateway English and math completion, fall-to-fall persistence, and narrowing or closing of opportunity gaps…

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…

This study provides a typological analysis of public, four-year institutions implementing programs for men of color (MoC). The purpose of the study is to expand our understanding of the institutional context and conditions in which these interventions operate. As more of these programs emerge, it is important to understand if and how institutional…

About 1 in 20 K-12 students are suspended from school each year. Students from marginalized groups -- including Black and Latinx students and students with individualized education plans (IEPs) -- experience suspension much more frequently than their peers. Empathic Instruction reduces the racial gaps in suspensions, but it does not close them…

Rationale: Few communication interventions for Latino Spanish-speaking (LSS) families with young children with language impairments and autism have been experimentally tested. "EMT en Espanol" is a culturally and linguistically adapted language intervention that has been effectively implemented by LSS caregivers of children with…

As open-access institutions serving diverse student populations, community colleges are perfect settings for broadening participation in computing efforts in higher education. The very nature of open access, however, places students with a wide variety of previous experience in the same introductory computer science classroom, intimidating the…

Considering the extensive social and private benefits that higher education generates, ensuring inclusive access and success is essential to achieve social justice and economic efficiency. With this premise in mind, this article reviews current knowledge about equity promotion policies in higher education and what is known about the effectiveness…

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…

Exclusionary school discipline practices and policies have contributed to the racial disparities in discipline for certain demographic of students, particularly Black students. As a result, many schools have adopted the school-wide positive behavioral interventions and supports (SWPBIS) framework to identify and address disproportionality, despite…

This thesis examines why, despite extensive research, women are underrepresented in engineering courses in many countries, including Ireland. The reasons for this underrepresentation are not well-understood. This study seeks to contribute to the understanding of women's decision-making regarding their studying engineering, through the application…

There is a need for rigorous experimental research on restorative practices in schools as a means to reduce exclusionary discipline and the disproportionate sanctioning of Black students, male students, and students with disabilities. The current study addressed this need in its evaluation of Morningside Center for Teaching Social Responsibility's…
