This action research study investigated how a community college faculty member can improve completion rates in introductory computer science (CS1) courses. Some students think the CS1 course is challenging or non-interesting after taking the class midway and then dropping out. Others would fail the exams repeatedly. Since the exams are mostly…

To realize more equitable technology futures, it is not enough to simply adapt technology to be more inclusive "after" it is created. We will also need to equip technology creators with the skills they need to critically reflect upon bias and exclusion "during" the technology design process. The question of how to best to…

Contributing to a growing body of research on broadening participation in computing for historically underrepresented racial communities (e.g., Black and Latinx), this qualitative study describes the knowledge (content and sources) six antiracist Computer Science (CS) teachers have about examples (and counterexamples) of modern techno-racism, a…

The rise in children's media use (Rideout & Robb, 2020) and the prioritization of STEM learning (Fayer et al., 2017) has led to the development of new STEM-related apps, TV shows, and other media for young children. One topic in this area gaining popularity is computational thinking (CT). Researchers refer to CT as an approach to problem…

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…

There is a significant gap in the number of women who go into college as computer science majors and decide to pursue the field in the workforce. There are challenges present for female students since the start of their education that their male counterparts do not face, which ultimately contributes to this gender gap. Such challenges include a…

This dissertation investigates the issue of gender stratification within engineering and other STEM-related fields. The dissertation is divided into three articles that address different aspects of the problem and propose potential solutions. Article 1 explores the persistent gender imbalance within STEM fields, particularly in engineering and…

This study aimed to examine the impact of cultural capital (Bourdieu, 1973; Bourdieu & Passeron, 1977) on the access and equity of C-STEM learners of color under the following four tenets of Yosso's (2005) Community Cultural Wealth model: aspirational, familial, social, and navigational capital. A theoretical framework of Critical Race Theory…

Computer Science (CS 1) offerings in most universities tend to be notoriously difficult. Over the past 60 years about a third of students either fail or drop out of the course. Past research has focused on improving teaching methods through small changes without changing the overall course structure. The premise of this research is that…

This research seeks to introduce concepts for programming, a key element of computing, to K-12 students. A central goal is to better understand the benefits of concept-integrated game mechanics in teaching basic programming concepts. The context of this research is also one of broadening participation. Thus the studies have been conducted in…

This dissertation uses a multi-case study approach to investigate teachers' use of computer science (CS) tools and pedagogical approaches in the classroom following their participation in a computer science integration professional development (PD) program. Seven teacher participants took part in a weeklong PD program and received follow up…

The cybersecurity landscape in the United States has rapidly evolved, marked by risk and novel threats (Georgescu, 2021; Siraj et al., 2021). Today, security mindsets are "widely accepted in the computer security community as … essential … for successful cybersecurity practice" (Peterson, 2021, para. 1), valuable to aspiring…

This dissertation presents the results and outcomes of an effort to design educational tools and curriculum to improve student learning in introductory programming courses. The work was conducted at the University of California, Merced (UC Merced), situated in the Central Valley of California, and home to a diverse student population. The findings…

The growth in the Latino population counts for half of the national population growth in the U.S, and that growth continues. Nevertheless, the gap in post-secondary educational attainment for Latinos is wide compared to whites and other non-Hispanics. Fewer Latino males are enrolling in science, technology, engineering, and mathematics…

Self-efficacy is seen as a barrier for youth, females in particular, to enter computer science (CS). In this study, I presented a near-peer mentoring model that focused on changing the mentee's self-efficacy in CS. The present study had three objectives: (a) to design a near-peer mentoring model (i.e., a conceptual model) around the sources of…
