This study investigated patterns in the development of computational thinking and programming expertise in the context of the Exploring Computer Science (ECS) program, a high school introductory CS course and professional development program designed to foster deep engagement through equitable inquiry around CS concepts. Prior research on programming expertise has identified three general areas of development — program comprehension, program planning, and program generation. The pedagogical practices in ECS are consistent with problem solving approaches that support the development of programming expertise. The study took place in a large urban district during the 2016–17 school year with 28 ECS teachers and 1,931 students. A validated external assessment was used to measure the development of programming expertise. The results indicate that there were medium-sized, statistically significant increases from pretest to posttest, and there were no statistically significant differences by gender or race/ethnicity. After controlling for prior academic achievement, performance in the ECS course correlated with performance on the posttest. With respect to specific programming concepts, the results also provide evidence on the progression of the development of programming expertise. Students seem to develop comprehension and planning expertise prior to expertise in program generation. In addition, students seem to develop expertise with concrete tasks prior to abstract tasks.

Equal Outcomes 4 All: A Study of Student Learning in ECS
This study investigated patterns in the development of computational thinking practices in the context of the Exploring Computer Science (ECS) program, a high school introductory CS course and professional development program designed to foster deep engagement through equitable inquiry around CS concepts. Past research indicates that the personal relevance of the ECS experience influences students' expectancy-value towards computer science. Expectancy-value is a construct that is predictive of career choices. We extended our research to examine whether expectancy-value influences the development of computational thinking practices. This study took place in the context of two ECS implementation projects across two states. Twenty teachers, who implemented ECS in 2016–17, participated in the research. There were 906 students who completed beginning and end of year surveys and assessments. The surveys included demographic questions, a validated expectancy-value scale, and questions about students' course experiences. The assessments were developed and validated by SRI International as a companion to the ECS course. Overall, student performance statistically increased from pretest to posttest with effect size of 0.74. There were no statistically significant differences in performance by gender or race/ethnicity. These results are consistent with earlier findings that a personally relevant course experience positively influences students' expectancy for success. These results expanded on prior research by indicating that students' expectancy-value for computer science positively influenced student learning.

With college advisory boards and potential employers consistently voicing their desire for engineers and scientists who can communicate well, work effectively in teams, and independently problem-solve, the Colleges of Engineering & Computer Science (ECS) and Natural Sciences and Mathematics (NSM) at Sacramento State University, a large, public, primarily undergraduate institution, have deployed two programs to explicitly address these skills for undergraduate science, technology, engineering, and mathematics (STEM) students. The goals of the NSF-funded Achieving STEM Persistence through Peer-Assisted Learning and Leadership Development (ASPIRE) project are to increase retention and decrease time to graduation for STEM students, as well as increase retention of women and underrepresented minorities (URM) in the STEM workforce by implementing evidence-based practices to promote student success during two critical transitions: 1) from lower-division to upper-division coursework in engineering; and 2) from upper-division coursework to an entry-level STEM career. ASPIRE aims to achieve these goals by: 1) adapting and implementing the NSM Peer Assisted Learning (PAL) program in gateway engineering courses; and 2) developing the Hornet Leadership Program which includes scaffolded opportunities for students to explore their leadership capacity and develop leadership skills. The main research questions for this study include: (1) Will the ECS PAL model and Hornet Leadership Program result in increased persistence and workforce readiness in STEM majors at a large, diverse university? (2) What attitude changes will this project have on students and faculty and the relationships between them? The first question is addressed through pre- and post-implementation student surveys and student course/GPA data. The second question is addressed through faculty surveys, faculty focus groups/interviews, and pre- and post-data from a faculty professional development workshop. In general, preliminary results from this study indicate the new ECS PAL program successfully attracts URM students and thus has the potential to support their persistence and STEM workforce readiness. Additionally, undergraduate students across both Colleges who participated in the inaugural Hornet Leadership Program gained non-technical skills and experiences directly linked to competitiveness and preparation for workforce entry and graduate programs. Finally, faculty surveys and the faculty professional development workshop indicate that faculty value student leadership development, but identify barriers to accomplishing this work.more » « less

The Maker Partnership Program (MPP) is an NSF-supported project that addresses the critical need for models of professional development (PD) and support that help elementary-level science teachers integrate computer science and computational thinking (CS and CT) into their classroom practices. The MPP aims to foster integration of these disciplines through maker pedagogy and curriculum. The MPP was designed as a research-practice partnership that allows researchers and practitioners to collaborate and iteratively design, implement and test the PD and curriculum. This paper describes the key elements of the MPP and early findings from surveys of teachers and students participating in the program. Our research focuses on learning how to develop teachers’ capacity to integrate CS and CT into elementary-level science instruction; understanding whether and how this integrated instruction promotes deeper student learning of science, CS and CT, as well as interest and engagement in these subjects; and exploring how the model may need to be adapted to fit local contexts. Participating teachers reported gaining knowledge and confidence for implementing the maker curriculum through the PDs. They anticipated that the greatest implementation challenges would be lack of preparation time, inaccessible computer hardware, lack of administrative support, and a lack of CS knowledge. Student survey results show that most participants were interested in CS and science at the beginning of the program. Student responses to questions about their disposition toward collaboration and persistence suggest some room for growth. Student responses to questions about who does CS are consistent with prevalent gender stereotypes (e.g., boys are naturally better than girls at computer programming), particularly among boys.more » « less

The Exploring Computer Science (ECS) curriculum provides foundational knowledge of Computer Science (CS) to high school students as a stand-alone course. ECS began in the Los Angeles Unified School District in the late 2000s where it gained eminence for broadening participation in computing (BPC), with Latinx students representing over 70% of enrollment. This experience report describes a partnership that consists of three Universities, dozens of school districts, the ECS team, and other stakeholders to bring the ECS curriculum in mainly rural school districts in Alabama that have a majority African-American student population. Sixty in-service teachers (one teacher per school) have received professional learning opportunities to gain knowledge and skills to teach ECS. Signs of early broader impacts are emerging: 78% of our ECS enrollment are underrepresented minority (URM) students with nearly half of the cohort consisting of female students. Students reported they were engaged in working collaboratively and sharing responsibilities with others. Furthermore, students who reported being more involved in the ECS course had deeper confidence in their ability to succeed in CS, reported greater overall outcomes, had more confidence in development of 21st century skills, found the course more relevant, were more motivated to persist in CS, and exhibited increased interest in CS careers. We provide a comprehensive description of the partnership’s accomplishments and the evaluation findings on student CS experiences and on teacher self-efficacy in ECS preparation and instruction. Our findings contribute to the BPC literature, specifically for schools with predominantly African-American enrollment in rural communities.more » « less

null (Ed.)The AP Computer Science A course and exam continually exhibit inequity among over- and under-represented populations. This paper explored three years of AP CS A data in the Chicago Public School district (CPS) from 2016-2019 (N = 561). We analyzed the impact of teacher and student-level variables to determine the extent AP CS A course taking and exam passing differences existed between over- and under-represented populations. Our analyses suggest four prominent findings: (1) CPS, in collaboration with their Research-Practice Partnership (Chicago Alliance for Equity in Computer Science; CAFÉCS), is broadening participation for students taking the AP CS A course; (2) Over- and under- represented students took the AP CS A exam at statistically comparable rates, suggesting differential encouragement to take or not take the AP CS A exam was not prevalent among these demographics; (3) After adjusting for teacher and student-level prior experience, there were no significant differences among over- and under-represented racial categorizations in their likelihoods to pass the AP CS A exam, albeit Female students were 3.3 times less likely to pass the exam than Males overall; (4) Taking the Exploring Computer Science course before AP CS A predicted students being 3.5 times more likely to pass the AP CS A exam than students that did not take ECS before AP CS A. Implications are discussed around secondary computer science course sequencing and lines of inquiry to encourage even greater broadening of participation in the AP CS A course and passing of the AP CS A exam.more » « less
