Description
Introductory programming courses, also known as CS1, have a specific set of expected outcomes related to the learning of the most basic and essential computational concepts in computer science (CS). However, two of the most often heard complaints in such courses are that (1) they are divorced from the reality of application and (2) they make the learning of the basic concepts tedious. The concepts introduced in CS1 courses are highly abstract and not easily comprehensible. In general, the difficulty is intrinsic to the field of computing, often described as "too mathematical or too abstract." This dissertation presents a small-scale mixed method study conducted during the fall 2009 semester of CS1 courses at Arizona State University. This study explored and assessed students' comprehension of three core computational concepts - abstraction, arrays of objects, and inheritance - in both algorithm design and problem solving. Through this investigation students' profiles were categorized based on their scores and based on their mistakes categorized into instances of five computational thinking concepts: abstraction, algorithm, scalability, linguistics, and reasoning. It was shown that even though the notion of computational thinking is not explicit in the curriculum, participants possessed and/or developed this skill through the learning and application of the CS1 core concepts. Furthermore, problem-solving experiences had a direct impact on participants' knowledge skills, explanation skills, and confidence. Implications for teaching CS1 and for future research are also considered.

Description
To meet the increasing demands for more STEM graduates, United States (U.S.) higher education institutions need to support the retention of minoritized populations, such as first-generation Latinas studying engineering. The theories influencing this study included critical race theory, the theory of validation, and community cultural wealth. Current advising practices, when viewed through a critical race theory lens, reinforce deficit viewpoints about students and reinforce color-blind ideologies. As such, current practices will fail to support first-generation Latina student persistence in engineering. A 10-week long study was conducted on validating advising practices. The advisors for the study were purposefully selected while the students were selected via a stratified sampling approach. Validating advising practices were designed to elicit student stories and explored the ways in which advisors validated or invalidated the students. Qualitative data were collected from interviews and reflections. Thematic analysis was conducted to study the influence of the validating advising practices. Results indicate each advisor acted as a different type of validating “agent” executing her practices described along a continuum of validating to invalidating practices. The students described their advisors’ practices along a continuum of prescriptive to developmental to transformational advising. While advisors began the study expressing deficit viewpoints of first-generation Latinas, the students shared multiple forms of navigational, social, aspirational, and informational capital. Those advisors who employed developmental and transformational practices recognized and drew upon those assets during their deployment of validating advising practices, thus leading to validation within the advising interactions.

Description
One of the primary aims of this action research study was to understand what happens when engineering faculty, staff, and faculty mentors engage in a professional development opportunity focused on improving instructional practices and faculty-student interactions. Since action research is aimed at using innovation to engage with a local problem of practice, for this research a Teaching Community of Practice Virtual Book Study (TCPVBS) innovation was designed, implemented, and studied. This study utilized a qualitatively driven Mixed Methods Action Research (MMAR) approach. Using Communities of Practice and Expectancy Value Theory as the primary guiding theoretical frameworks, the TCPVBS innovation was designed to prioritize a learner-centered approach, fostering collaborative knowledge construction among participants on book study topics through learning materials designed to promote an inclusive lens. Participants in the study included faculty, faculty mentors, and staff at Southwest University, primarily in the College of Engineering. Data was collected in the form of pre- and post-surveys, meeting artifacts, a focus group, semi-structured individual interviews, and reflection journals. A thematic analysis was conducted using codebooks. The study concluded that a faculty book study was a valuable learning opportunity for teaching professional development. Further research is needed to understand how instructional practices and student outcomes are impacted by the TCPVBS innovation. Implications for future research related to engineering faculty culture and embedding an inclusive lens are presented and discussed.
