   CSAwesome is a new approved curriculum and professional development (PD) provider for the Advanced Placement (AP) Computer Science (CS) A high school course. AP courses are taken by secondary (typically ages 14-19) students for college placement and/or credit. CSAwesome's free curriculum and teacher resources were developed in 2019 by adapting the CSA Java Review ebook on the open-source Runestone platform. The goals of CSAwesome are to broaden participation in the AP CSA course and to support new-to-CS students and teachers as they transition from the AP Computer Science Principles (CSP) course to the AP CSA course by using inclusive teaching practices and curriculum design. The AP CSP course is equivalent to a first course for non-majors at the college level, while the AP CSA course is equivalent to a first course for majors. Currently, AP CSA attracts a much less diverse student body than AP CSP. This new curriculum supports student engagement and scaffolded learning through an interactive ebook with embedded executable and modifiable code (Active Code), a variety of practice types with immediate feedback, and adaptable mixed-up code (Parsons) problems. Collaborative learning is encouraged through pair programming and groupwork. Our pilot Professional Development (PD) incorporates inclusive teaching strategies and active recruitment with the goal of broadening participation in CSA. This paper presents the design of the CSAwesome curriculum and teacher professional development and initial results from the curriculum use and pilot PD during the first year of CSAwesome.

2. Computer Science Principles for Teachers of Blind and Visually Impaired Students

   https://doi.org/10.1145/3287324.3287453  

   Stefik, Andreas; Ladner, Richard E.; Allee, William; Mealin, Sean (January 2019, Proceedings Article published 2019 in Proceedings of the 50th ACM Technical Symposium on Computer Science Education - SIGCSE '19)

   The College Board's AP Computer Science Principles (CSP) content has become a major new course for introducing K-12 students to the discipline. The course was designed for many reasons, but one major goal was to broaden participation. While significant work has been completed toward equity by many research groups, we know of no systematic analysis of CSP content created by major vendors in relation to accessibility for students with disabilities, especially those who are blind or visually impaired. In this experience report, we discuss two major actions by our team to make CSP more accessible. First, with the help of accessibility experts and teachers, we modified the entire Code.org CSP course to make it accessible. Second, we conducted a one-week professional development workshop in the summer of 2018 for teachers of blind or visually impaired students in order to help them prepare to teach CSP or support those who do. We report here on lessons learned that are useful to teachers who have blind or visually impaired students in their classes, to AP CSP curriculum providers, and to the College Board.

3. Engaging Black Female Students in a Year-Long Preparatory Experience for AP CS Principles

   https://doi.org/10.1145/3408877.3432560

   In 2020, over 116,000 students took the Advanced Placement Computer Science Principles (AP CSP) Exam. Although Black female students have participated in AP CSP at higher rates than for the AP CSA course, their representation is still disproportionately lower than the school population of Black females. In this Experience Report, we present the early results of an NSF-sponsored effort that provides an AP CSP preparatory experience and CS career awareness to Black female students from rural, urban, and suburban communities in the state of Alabama. At the project’s core is a peer-learning community (PLC) facilitated by Black female teachers with deep knowledge of AP CSP. An intensive summer experience prepares students for the AP CSP course through culturally-responsive, project-based learning experiences designed to connect advanced computing concepts to the students’ personal lives and career aspirations. Interactions and support continue throughout the academic year to facilitate AP exam readiness. Online interactions among the PLC members serve to mitigate the barriers that young women of color typically encounter when pursuing CS education, increasing their persistence and success in CS. We examined whether students’ project participation enhances self-efficacy and perceived competency in CS, increases positive attitudes, awareness, and desire to pursue CS studies and careers, and mitigates perceived socio-cultural barriers to pursue studies and careers in CS. Our initial findings include AP CSP examination qualifying rates (87.5%) that exceed the 2019 national/statewide rates for all subgroups (including Alabama White male students), increased perceptions of Black females as belonging in CS, and gains in computing self-efficacy throughout the academic year.

4. Why Do Students Enroll in AP CSP?

   https://doi.org/10.1109/RESPECT51740.2021.9620546

   CS4All initiatives nationwide have been working to increase and diversify student participation in computer science (CS). One intentional effort to broaden participation in CS was the launch of the Advanced Placement (AP) CS Principles (CSP) course, which sought to increase the number of students enrolling in CS overall as well as from groups historically underrepresented in CS. Early AP CSP implementation results are encouraging and have identified the need to better understand essential supports for quality implementation, differential student experiences and outcomes, and students’ motivations for course enrollment. In this paper, we explore the motivations that affect student decisions to take AP CSP using survey data collected during fall 2019 in the New York City public schools, the largest school district in the U.S. This work is part of an ongoing research-practice partnership that provides teacher and school supports for AP CSP implementation and aims to improve outcomes especially for female, Black, and Latinx students in high-need schools. In particular, we examine how students’ reasons and influences for enrolling in AP CSP may differ based on self-identified gender and race/ethnicity. Our findings indicate that while most students shared an interest in learning more about CS, students from communities historically underrepresented in computing are more likely to report being placed in the course and to be influenced by guidance counselors. The implications of these results highlight the importance of understanding why students choose AP CSP in developing recruitment resources, student engagement strategies, and supports for implementation.

5. Broadening Participation and Success in AP CSA: Predictive Modeling from Three Years of Data

   https://doi.org/10.1145/3408877.3432421

   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.
