Objective: Evidence suggests the increased prevalence of diabetes among South Asian (SA) adolescents is due to their genetic risk profile. The South Asian Adolescent Diabetes Awareness Program (SAADAP) is a pilot intervention for SA youth in Canada with a family history of type 2 diabetes mellitus (T2DM). We sought to investigate changes in (1)…

Establishment of online communities in distance education has been linked to improved engagement, retention, and learning outcomes. This study investigates how online community building was fostered in the text-based Discussion Board (DB) and multimodal VoiceThread (VT) in one of the postgraduate units offered by Open Universities Australia.…

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…

The Charles A. Dana Center at the University of Texas at Austin launched the Dana Center Mathematics Pathways (DCMP) in 2011. The initial version of DCMP diversified developmental and college-level math course content, separating it into distinct pathways that better aligned with students' career interests. It also streamlined the developmental…

The Illinois Department of Children and Family Services (DCFS) contracted with three child welfare providers that operate transitional living (TLP) or independent living (ILO) programs (or both) to implement LifeSet, an intensive case management program developed by Youth Villages, for youth in care who are 17.5 to 21 years old. LifeSet helps…

First-generation college students may experience a mismatch between their cultural backgrounds, which tend to emphasize interdependent cultural norms (i.e., group achievements, connection with others, and taking actions that foster fitting in) and universities, which tend to emphasize independent cultural norms (i.e. individual achievements,…

This dissertation examined the relationship between participation in an academic coaching program and retention for community college students enrolled in developmental education courses. With low retention and completion rates for students beginning in developmental courses, support programs to improve student success are needed. This…

This dissertation presents two essays on econometric methods for program evaluation and policy choice. In Chapter 1, I develop a statistically optimal way of using data to make policy decisions when the performance of counterfactual policies is only partially identified. Specifically, I consider a class of statistical decision problems in which…

Background: Community colleges have the potential to be powerful vehicles for social mobility in the United States. As institutions with tuition rates that are a fraction of the cost of four-year public and private colleges, they are a critical resource for students looking for a relatively less expensive and more flexible option to attain a…

Dual enrollment allows high school students to participate in college courses, earning both high school and college credits. Although many high schools offer dual enrollment to all students, past research has demonstrated a significant gap in the participation of low-income students and students of color compared to their White and Asian…

Federal legislation for students with disabilities mandates that all students receive appropriate and relevant instruction across environments to improve postsecondary outcomes across domains. Teachers and parents alike have found that one way to meet individual student needs and increase instructional opportunities for students with disabilities…

Since professional learning is about shifting adult mindsets and behavior, it is work that frequently challenges assumptions, expectations, beliefs, instructional practices, and long-standing habits. To have meaningful and productive conversations about evaluation and data, educators must be equipped with effective practices and tools that allow…

Unsafe and violent schools are a widespread problem in South Africa. This paper argues that Adverse Childhood Experiences (ACEs) contribute to this phenomenon. While various individual and community-level interventions to address ACEs have been reported on, the contribution of safe parks towards preventing school violence has not yet been…

Background: Undergraduate research programs have been shown to have positive effects on student outcomes like retention and academic achievement. This study contributes to the very limited body of causal research on mentored undergraduate research programs (also known as apprentice-style research experiences, or AREs) by measuring the short- and…

The COVID-19 pandemic has catalyzed the widespread adoption of distance learning, necessitating a comprehensive understanding of how teacher knowledge evolves within the context of Teacher Professional Education (TPE) programs. Some research endeavors may employ evaluation methodologies that inadequately capture the nuanced dimensions of…
