School climate is a well-studied issue in educational research. However, surveys of school climate tend to be analyzed using item-centered as opposed to person-centered methods. The current study evaluated the 2018 South Carolina School Climate Survey using advanced applications of mixture modeling in an attempt to identify latent profiles at the…

The video game industry is a global multibillion dollar industry with millions of players. The process of developing video games is essential for the continued growth of the industry, and developers need to employ effective strategies that will help them to create successful games. The purpose of this explorative qualitative single case study was…

In this dissertation, I study those research practices and values which limit trans-disciplinarity among academics of science teaching & learning. I consider trans-disciplinarity an ethically imbued practice that enables thinking about the productivity of our research practices and makes possible flows of connectivity in the generation of our…

Mixed methods (MM) research is an emergent methodology that involves collecting, analyzing, and intentionally integrating qualitative and quantitative data in a study. MM is increasingly used by graduate students and scholars across contexts. These researchers? practices of MM research, however, have been found to be limited in the literature, and…

The goal of this project is to examine the development and current state of U.S. education research through the lens of computational social science. The dissertation comprises three studies which use distinct data--dissertations, library logs, patents--and methods-- topic models, navigational networks, semantic networks--to approach the field. In…

Background: Higher education is more diverse than ever with a drastic increase in college enrollment over the past two decades by those who have not traditionally sought undergraduate credentials, including students with disabilities (Espinosa, Turk, Taylor, & Chessman, 2019; Clouder et al., 2020). Despite the growing demographic diversity of…

The field of comparative and international education has followed methodological trends in social science research since the merging of the "twin" field after World War II. With increase in the use of mixed methods research about three decades ago, comparative and international education journals and scholars have worked rigorously to be…

This dissertation responds to two aspects of the homesickness literature: its characterization as a mental health concern, and its lack of empirical attention in the United States. The purpose of this study was to develop a theoretical understanding of homesickness oriented to an affirming and sociocultural lens, and to do so in the context of…

This dissertation sought to use PhotoVoice, an arts-based research method, as a way for pre-college and college students to decide on an area of study and career path. This study called upon the aid of student-participants to carry out the research and academic professionals to help in examining the research. Using a framework set in Strength…

Universities are increasingly encouraging their undergraduates to become mentors to others, yet relatively little research has been done to empirically understand the impact of this work on the mentors themselves. Therefore, the overall goals of this work were: (1) To evaluate the types of studies that have been conducted on the impacts of serving…

Implementation fidelity is considered an indicator of an intervention's internal validity. In reading research, while student outcome measures are often well described, measures of implementation fidelity have received far less attention. Although researchers have become interested in the relation between implementation fidelity and student…

Our institutional approaches to problems in the changing global landscape of internationalized higher education are being challenged, and many scholars call for new approaches for understanding and addressing the complex problems we face (e.g., la paperson, 2017; Lee, 2021; Patel, 2016; Stein, 2019, 2020). The COVID-19 pandemic has sped up the…

As the transactional perspective on occupation continues to evolve (Dickie, Cutchin, & Humphry, 2006; Bailliard, Aldrich, & Dickie, 2012; Cutchin, Dickie & Humphry, 2017), the epistemological advances toward a more communal/less individual-centered understanding of occupation beckon thoughtful methodological shifts, as well. Early…

The prevalence of adolescents and adults with autism spectrum disorder (ASD) is growing worldwide. There is a lack of services to support adolescents and adults with ASD in different areas including social-communication intervention. To fill these research gaps in the literature, the three studies in this dissertation extended the literature on…

This dissertation is aimed at investigating the impact of missing data and evaluating the performance of five selected methods for handling missing responses in the implementation of Cognitive Diagnostic Models (CDMs). The five methods are: a) treating missing data as incorrect (IN), b) person mean imputation (PM), c) two-way imputation (TW), d)…
