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…

Researchers have studied children's exposure to television and the impact it has on children's academic development, and have discovered that educational television programs may positively influence children's vocabulary growth (Fuenzalida, 2017; Heintz & Wartella, 2012; Larson & Rhan, 2015; Linebarger, Moses, Liebeskind, & McMenamin,…

I situate computer programming as a cultural practice. I develop this perspective in two ways: exploring how programming practices can support intercultural learning, and examining how programming tools themselves embed cultural assumptions and values. For the former, I study how relationships across difference are formed over computing activities…

This dissertation presents the first Systemic Functional Linguistics-based analysis of the teaching/learning of computational thinking through computer programming and comprehensive analysis of discourse of a whole computer programming course at any educational level. The current educational research raises questions about the nature of authentic…

Most existing autograders used for grading programming assignments are based on unit testing, which is tedious to implement for programs with graphical output and does not allow testing for other code aspects, such as programming style or structure. We present a novel autograding approach based on machine learning that can successfully check the…

This dissertation follows a manuscript-style format, beginning with an introduction and literature review, followed by three distinct studies and a concluding section. All three studies use "Lucky Codes," an educational board game designed to foster computational thinking skills in elementary students, as the intervention. The first…

This qualitative study explored high school students' engagement with a unit where video games and video game materials were incorporated into an English Language Arts classroom. Over several weeks, students engaged with video game content and composed their own video games using the free online platform, Scratch. The purpose of the study was to…

Computational thinking (CT) has been supported as an important skill every young person should possess for the 21st century, with possible implications for problem-solving, self-expression, and creativity. Numerous initiatives, both within and outside classroom settings, have been developed in response to policy mandates aiming at broadening…

While there is high demand for university computer science (CS) courses, students often struggle when learning to program. Prior work has identified that student perceptions of their programming ability may contribute to these challenges. For example, studies show that students often perceive that they do not belong, are not capable of succeeding,…

The rise in demand for computer programming jobs has created a significant need for computer programming training. Online learning can be an effective tool for meeting the needs of these job demands. The challenge for universities is that computer programming is perceived as a difficult course by many students (Askar & Davenport, 2009; Baser,…

The problem that inspired this study is that Turkish students' mathematics rankings on global exams such as The Program for the International Students Assessment (PISA) and Trends in International Mathematics and Science Study (TIMMS) had been below the average for many years, a problem that may have rooted in children's early experiences with…

The STEAM (Science, Technology, Engineering, Arts, and Mathematics) learning model is touted by its proponents for its potential in broadening access and participation in STEM learning through deep, authentic engagement in integrated STEM and arts practices. One location STEAM learning occurs is the new media arts classroom, where learners use…

With ongoing concerns in undergraduate computer science education like growing enrollment and broadening participation, there is a need for reform. While there are many stakeholder perspectives to consider in reforms, students deserve to be prioritized because they face a variety of environmental challenges that lead to negative outcomes like…

The overarching theme of this research project is to build a machine-accessible and mathematically precise abstraction of human body movement through experiments in programming an articulated puppet that imitates the human body structure and mobility within a "Real-Time Interactive Computer Animation" (RTICA). Human movement has been the…

Data science encompasses the most prominent collection of methods for creating scientific knowledge in the 21st century. Currently, data scientists must navigate a wide-ranging and often incoherent ecosystem of tools, in addition to organizing sociotechnical interactions with colleagues across many fields of expertise. This predicament motivates…
