Many middle school students come to Computer Science (CS) classes without any previous CS instruction or any Computational Thinking (CT) skills that are needed to be successful. To overcome this, many curriculums and programming environments have been used to engage students and to instill a love of CS. Which curriculum should be used to develop…

Software vulnerabilities in commercial products are an issue of national importance. The most prevalent breaches are input validation vulnerabilities, and these are easily avoidable. This dissertation contributes to cybersecurity education with a set of hands-on interventions tailored for three CS courses, a set of reflection prompts to encourage…

Quantum mechanics is notoriously challenging, and research has found that students struggle with many common difficulties when learning it. It is also proving to be a critical piece of many exciting fields that are all but assured to see great development and expansion in the coming years; the Second Quantum Revolution is upon us. Quantum…

Impending climate crises, profound wealth inequality and unprecedented vulnerability to global catastrophe at the hands of technology make working towards justice a necessity, and a desperate one at that. However, engaging in work towards justice requires deconstructing the dominant narratives and norms that restrict what actions are permissible…

Block-based programming environments have become increasingly commonplace in computer science education. Despite a rapidly expanding ecosystem of block-based programming environments, text-based languages remain the dominant programming paradigm outside of educational contexts, motivating the transition from block-based to text-based programming.…

The national conversation about STEM education continues. While math and science have been a constant in K-12 and higher education, curriculum in technology and engineering have not been consistently part of the tapestry of American education. As such, there is a dearth of qualified candidates for the ever-growing number of computer science and…

Initiatives geared toward broadening participation in computing research have addressed the longstanding underrepresentation of various populations - including women, Black people, Latinx people, and persons with disabilities. Although there has been an increase in underrepresented populations participating in computing, building upon these…

This dissertation focuses on strategies and techniques to enhance code comprehension skills among students enrolled in introductory computer science courses (CS1 and CS2). We propose a novel tutoring system, "DeepCodeTutor," designed to improve the code comprehension abilities of novices. DeepCodeTutor employs scaffolded self-explanation…

This study explored the role of faith in the motivation of undergraduate computer science students and considered the implications for Christian Higher Education in the United States, by reviewing the existing literature on the subject. Academic motivation of computer science students is a global concern evidenced by studies around the world that…

Transgender and gender nonconforming (TGNC) students are underrepresented in CS education and have been found to leave the field at higher rates than their counterparts. While there is a great deal of Computer Science (CS) education research focused on other underrepresented groups, it rarely includes those who are TGNC. Overall, there is a dearth…

The meteoric rise in software and technology has altered the paradigm of information security and privacy. Classified information, stored earlier behind locked doors, is now stored on the internet on servers that can be accessed from anywhere on the globe. As a result of these advancements, we are now vulnerable to cyber-attacks. Cyber-attacks are…

The purpose of this study was to explore how elementary school teachers think about equity in relation to their goals in their computer science instruction, and to explore the strategies they articulated to make their practice more equitable. States are mandating computer science standards and instruction and requiring schools to teach the content…

Introductory computer programming (i.e. CS1) is the entry point into the computer science major at higher education institutions worldwide. It introduces foundational concepts to students that are then built upon in future courses. Computer science as a whole has struggled to attract and retain students in the major, particularly women and…

This convergent parallel mixed methods study with qualitative and quantitative content analysis was conducted to analyze and describe the cognitive complexity of the publicly released Advanced Placement Computer Science Principles Exam questions compared to the language of higher-order thinking found in research literature. Hess' Cognitive Rigor…

Efforts to increase the participation of groups historically underrepresented in computing studies, and in the computing workforce, are well documented. It is a national effort with funding from a variety of sources being allocated to research in broadening participation in computing (BPC). Many of the BPC efforts are funded by the National…
