This dissertation is about a particular style of research. The philosophy of this style is that in order to scientifically understand deep learning, it is fruitful to investigate what happens when neural networks are trained on simple, mathematically well-defined tasks. Even though the training data is simple, the training algorithm can end up…

Piecewise latent growth modeling (PLGM) is a class of longitudinal models using a structural equation modeling framework to describe stage-like, discontinuous change of individuals over time. PLGM breaks the overall time window into non-overlapped segments where separate functions can be fitted to represent differential growth patterns for each…

Interest in Science, Technology, Engineering, and Mathematics (STEM) education is more important than ever since the Pandemic ravaged our nation's medical resources and personnel. This exploratory study, intended to establish and characterize potential identifiers and markers of student interest development in an inquiry-driven learning…

There has been extensive research into the underrepresentation of minoritized students in STEM disciplines since the 1990s with limited success in improving the representation of Black women in math-intensive STEM fields. This dissertation aims to address how the guiding tenets of critical quantitative (QuantCrit) methods work when used with…

In educational contexts, students often self-select into specific interventions (e.g., courses, majors, extracurricular programming). When students self-select into an intervention, systematic group differences may impact the validity of inferences made regarding the effect of the intervention. Propensity score methods are commonly used to reduce…

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…

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…

Most social communication tests used to measure change in young children with autism spectrum disorder have not undergone rigorous psychometric evaluation. Notably, and most relevant to the early intervention literature, there is little information on the sensitivity of these measures to change over time, despite their frequent use. Further, most…

This dissertation format includes three articles that each address a unique aspect of the current barriers to access that individuals with disabilities with intersectional identities experience in their academic and career paths to attainment of a doctoral degree. The first article contains an analysis of data drawn from the High School…

The purpose of this dissertation was to examine the successful implementation of social media strategies in multiple organizations. Examining the factors an organization used to implement social media can provide the understanding of the benefits and risks associated with this technology. Some businesses are considered successful using social…

Translational research (TR) is the process of bringing innovations from basic science into applied science, usually referring to the practice of medicine. It has been assumed that cross-disciplinary collaboration, or interdisciplinarity research (IDR), is essential to translation. Yet there is a gap in the literature regarding the interaction…

This dissertation contains a collection of essays centered on the relationship between theoretical model-building and empirical evidence-gathering in linguistics and related language sciences. The first chapter sets the stage by demonstrating that the subject matter of linguistics is manifold, and contending that discussion of relationships…

This dissertation draws on data from a quarter-long case study implementing a number of social science and humanities research methods. This study was conducted at the University of Washington in two sections of First-Year Composition and investigates the boundary-marking interactions that occur in a writing class by tracing the experiences of…

Undergraduate research is often regarded as the most powerful high impact practice because it encompasses several high impact practice strategies (e.g. faculty-student mentorship, collaborative learning, common intellectual experiences) within one experience. First-generation college Students of Color are often excluded from undergraduate research…

In recent years, efforts are being made at all levels of education to prescribe instructional actions that would optimize desired instructional outcomes. Component display theory (CDT), a micro level instructional design theory proposed by Merrill (1983), offers guidelines and prescriptions to present components of instruction to teach facts,…
