1. Coding Science Internships: Broadening Participation in Computer Science by Positioning Coding as a Tool for Doing Science

   https://doi.org/10.1145/3328778.3372632  

   Greenwald, Eric; Krakowski, Ari (February 2020, The 51st ACM Technical Symposium on Computer Science Education)

   Computational tools, and the computational thinking (CT) involved in their use, are pervasive in science, supporting and often transforming scientific understanding. Yet, longstanding disparities in access to learning opportunities means that CT’s growing role risks deepening persistent inequities in STEM [2]. To address this problem, our team developed and studied two 10-lesson instructional units for middle school science classrooms, each designed to challenge persistent barriers to equitable participation in STEM. The units aim to position coding as a tool for doing science, and ultimately, encourage a broader range of students, and females in particular, to identify as programmers. Students who participated (n=391) in a recent study of the units demonstrated statistically significant learning gains, as measured on an external assessment of CT. Learning gains were particularly pronounced for female students. Findings suggest that students can develop CT through instruction that foregrounds science, and in ways that lead to more equitable outcomes.

2. Examining the What, Why, and How of Multilingual Student Identity Development in Computer Science

   https://doi.org/10.1145/3500918

   Abstract: Developing student interest is critical to supporting student learning in computer science. Research indicates that student interest is a key predictor of persistence and achievement. While there is a growing body of work on developing computing identities for diverse students, little research focuses on early exposure to develop multilingual students’ interest in computing. These students represent one of the fastest growing populations in the US, yet they are dramatically underrepresented in computer science education. This study examines identity development of upper elementary multilingual students as they engage in a year-long computational thinking curriculum, and follows their engagement across multiple settings (i.e., school, club, home, community). Findings from pre- and -post surveys of identity showed significant differences favoring students’ experiences with computer science, their perceptions of computer science, their perceptions of themselves as computer scientists, and their family support for computer science. Findings from follow-up interviews and prior research suggest that tailored instruction provides opportunities for connections to out-of-school learning environments with friends and family that may shift students’ perceptions of their abilities to pursue computer science and persist when encountering challenges.

3. From superficial to foundational: Integrating cultural relevance into computer science curriculum (poster abstract)

   Nolte, A.; Codding, D.; Rolón-Dow, R.; Mouza, C.; Pollock, L. (January 2023, NARST)

   Female and racially minoritized groups continue to be underrepresented in computer science (CS) and STEM careers, despite ongoing efforts to diversify the field. One way to promote the success of minoritized students in CS education is to incorporate culturally relevant pedagogy (CRP) into CS curriculum and instruction. This work explores the ways that teachers integrated CRP in their lesson plans after participating in CRP-focused professional development (PD) sessions delivered during a week-long PD aimed at improving and diversifying CS education. Our analysis of the lesson plans reveals that teachers integrated CRP at levels ranging from superficial to foundational. At the superficial level, teachers treated CRP as an “add-on” strategy with minimal relevance to the lesson content. At the foundational level, CRP was central to student mastery of core content learning. This work contributes to our understanding about how teachers approach the concept of relevance when integrating CRP in CS education. Findings have implications for approaches to PD design that support teachers in integrating CRP in CS education, as well as other STEM classrooms.

4. Multi-Disciplinary Orientation Sessions for Fist-Year Students in Engineering, Engineering Technology, Physics, and Computer Science

   Novoa, C.; Martinez, Ortiz A.; Talley, K.G. (January 2016, ASEE Annual Conference proceedings)

   This work in progress is motivated by a self-study conducted at Texas State University. The study revealed that the average second year science, technology, engineering and math (STEM) student retention rate is 56% vs. 67% for all majors, and that 16% of STEM majors are female while 57% of all undergraduate students are female. Using these statistics, the authors identified the need to offer motivating experiences to freshman in STEM while creating a sense of community among other STEM students. This paper reports on the impact of two interventions designed by the authors and aligned with this need. The interventions are: (1) a one-day multi- disciplinary summer orientation (summer15) to give participants the opportunity to undertake projects that demonstrate the relevance of spatial and computational thinking skills and (2) a subsequent six-week spatial visualization skills training (fall 2015) for students in need to refine these skills. The interventions have spatial skills as a common topic and introduce participants to career applications through laboratory tours and talks. Swail et al.[1] mentions that the three elements to address in order to best support students’ persistence and achievement are cognitive, social, and institutional factors. The interventions address all elements to some extent and are part of an NSF IUSE grant (2015-2018) to improve STEM retention. The summer 2015 orientation was attended by 17 freshmen level students in Physics, Engineering, Engineering Technology, and Computer Science. The orientation was in addition to “Bobcat Preview”, a separate mandatory one-week length freshman orientation that includes academic advising and educational and spirit sessions to acclimate students to the campus. The effectiveness of the orientation was assessed through exit surveys administered to participants. Current results are encouraging; 100% of the participants answered that the orientation created a space to learn about science and engineering, facilitated them to make friends and encouraged peer interaction. Eighty percent indicated that the orientation helped them to build confidence in their majors. Exit survey findings were positively linked to a former exit survey from an orientation given to a group of 18 talented and low-income students in 2013. The training on refining spatial visualization skills connects to the summer orientation by its goals. It offers freshman students in need to refine spatial skills a further way to increase motivation to STEM and create community among other students. It is also an effective approach to support students’ persistence and achievement. Bairaktarova et al.[2] mention that spatial skills ability is gradually becoming a standard assessment of an individual’s likelihood to succeed as an engineer. Metz et al.[3] report that well-developed spatial skills have been shown to lead to success in Engineering and Technology, Computer Science, Chemistry, Computer Aided Design and Mathematics. The effectiveness of the fall 2015 training was assessed through comparison between pre and post tests results and exit surveys administered to participants. All participants improved their pre-training scores and average improvement in students’ scores was 18.334%.
