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…

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…

A disproportionate number of European American male students are enrolled in cyberscience undergraduate degree programs, despite attempts to attract diverse student populations in the field. The purpose of the basic qualitative study was to gain a better understanding on how cyberscience academic experts perceive the challenges related to the…

Universities are reflections of our societies and are tasked with educating the next generation of experts. The computer science (CS) phenomenon, with its high-paying jobs, attracts more students than ever to the CS undergraduate major. One may wonder why women are underrepresented in the CS major if they constitute half of university enrollment…

Women are underrepresented in science, technology, engineering, and math (STEM) in higher education institutions and the technology field and vulnerable to attrition. The reviewed literature suggests that the impact of other factors, beyond students' academic performance, leading to well-being and success and affecting female students' retention…

This doctoral dissertation documents the experiences of women (student and faculty) in computer science programs. The research emerges from the literature on the gender gap in computing and video gaming. Thus, the author seeks to find the meaning that participants have granted to their experiences as undergraduate students and faculty, in a…

Assessments are some of the most common tools used to evaluate student learning. While exams have always been a part of evaluating how well students learn and retain information, the most effective way to administer them has always been debated. However, remarkably few studies have compared online and paper testing, and even fewer have examined…

This study sought to address the gap in knowledge about the effect of UDL features on asynchronous online postsecondary learners' achievement, engagement, and self-efficacy. The study also described a process for redesigning an online course to incorporate UDL components and provided specific examples of the implemented UDL guidelines. The study…

All engineering careers require some level of programming proficiency. However, beginning programming classes are challenging for many students. Difficulties have been well-documented and contribute to high drop-out rates which prevent students from pursuing engineering. While many approaches have been tried to improve the performance of students…

The opportunity to innovate, experiment, and take chances in the classroom should be accessible to all students regardless of the social identities they hold; however, white women and women of color (WOC) in male-dominated physics, engineering, math and computer science (PEMC) learning environments, and STEM broadly, have been expected to take…

All students studying Computer Science (CS) deserve to have their basic psychological need for belonging satisfied. In this dissertation, I present two studies of belonging among CS students at the University of Washington-Paul G. Allen School of Computer Science and Engineering. In the first study, my collaborators implemented a resubmission…

Software modeling is an integral practice for software engineers especially as the complexity of software solutions increase. There is precedent in industry to model information systems in terms of functions, structures, and behaviors. While constructing these models, abstraction and systems thinking are employed to determine elements essential to…

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…

Over the past 20 years, the field of computer science has experienced a growth in student interest. Despite this increase in participation rates, longstanding gender gaps persist in computer science. Recent research has examined a wide variety of individual factors (e.g., self-efficacy, sense of belonging, etc.) that impact student interest and…

The increase in distance learning offerings and the deficit in providing an equivalent engagement mechanism for haptic subjects for online learners is stimulating educators to seek new pedagogical methods to meet the needs of the curriculum. A quantitative quasi-experimental study deploying a two nonequivalent groups design was conducted to…
