Physics education research to date has predominantly focused on the undergraduate level. This has left critical avenues of research in graduate education relatively understudied and has motivated much of my research. Numerous studies across the education research landscape have analyzed undergraduate admissions practices, but few have critically…

Using the Trends in International Mathematics and Science Study Data (TIMSS) 2015 dataset, this study examines 30 different contextual indicators to determine significant predictors of girls' mathematics achievement globally. The study design employs three nested levels in the hierarchical linear model (individual, classroom, and nation) to…

Building off seminal works on community including McMillan and Chavis, Lave and Wenger, Graves, and Wenger et al, the Institutional, Program, and Professional (IPP) community framework for online allows students, faculty, administrators, and alumni the opportunity to consider how to support community beyond online courses into programs, the…

The present dissertation project investigated relationship enhancement following a brief self-disclosure task (i.e., the Fast Friends Procedure; FFP) via self-report and observational data. Thirty-three undergraduate couples dating for less than six months asked and answered questions that required increasingly higher levels of self-disclosure for…

The primary purpose of the current study was to predict the likelihood of enrollment in Graduate School based on three independent variables: cost, time-to-completion, and return on investment. To achieve this purpose, a Z-test for the hypothesis of two proportions was utilized to create a predictive model. The model aimed to help institutional…

This dissertation is composed of three studies linking general education astronomy to student performance, course-taking, graduation, and identity. The first study examined demographic and academic predictors of astronomy performance among a cohort of N=1,909 community college students enrolled in astronomy courses in a large suburban community…

The purpose of this ex post facto quantitative study was to examine the correlation between the scores of preservice teachers on 240 Tutoring STR practice tests and their scores on the actual STR exam and to explore the extent to which test preparation programs predicted performance on certification exams. In addition, this study compared the…

The prevalence of healthcare provider burnout is increasing globally, with medical trainees being especially susceptible. The purpose of this quantitative cross-sectional correlational study was to examine the relationship between the perceptions of the Clinical Learning Environment (CLE) and burnout among medical trainees within a single medical…

This study has provided insights into the factors that influence doctoral student quantitative course success but also increased the lens for further research. The current study explored the relationship between master's degree type, years since completing a master's degree, self-efficacy scores and cumulative GPA in Research I, Research II, and…

Objective: Collegiate-athletes are vulnerable to mental health disorders, such as anxiety and depression, yet very little is known about what variables might predict the use of on-campus mental health services among them. The purpose of this study was to investigate the utility of Andersen's Behavioral Model (ABM) in predicting the use of…

Institutions of higher education are under increased scrutiny as graduation rates decline while student loan debt soars. One proposed strategy to improve completion rates is to give additional support to those students who are most at-risk of leaving college before graduating. Research has shown that first-generation students are more likely to…

Professionalism is a required curricular component in accredited medical laboratory science (MLS) programs in the United States and is a critical element for career success and optimal patient care. A standardized definition of professionalism in MLS, however, has yet to be established. This poses a challenge to MLS programs when pertaining to…

Executive functioning (EF) is found to be a powerful predictor for children's school readiness and long-term school outcomes. However, the current research base indicates that children with autism may have an increased likelihood of experiencing deficits in EF or delayed developmental trajectories. Additionally, although there is ample evidence…

The number of students with autism spectrum disorder (ASD) rises each year, along with a demand for use of evidence-based intervention (EBI) in schools. Applied behavior analysis (ABA) is widely recognized as an effective EBI for students with ASD, making it a skill that contributes to school psychologists' (SPs) effectiveness. This study reviewed…

Purpose: The purpose of this scholarly project was to determine if GRE scores (verbal reasoning, quantitative reasoning, and analytical writing) predict first-time pass rate on the NCE. This project also investigated the correlation between first-time pass rate on the NCE and the individual covariates of age at program matriculation, sex, race,…
