Background and Context: While assessment of computational thinking concepts, practices, and perspectives is at the forefront of K-12 CS education, supporting student communication about computation has received relatively little attention.

Objective: To examine the usability of process-based portfolios for capturing students’ communication about their computational practices regarding the process of making electronic textile projects.

Method: We examined the portfolios of 248 high school students in 15 introductory CS classrooms from largely underserved communities, using a formal rubric (top-down) to code computational communication and an open-coding scheme (bottom-up) to identify computational practices described.

Findings: Students demonstrated stronger …

Communicating Computational Concepts And Practices Within High School Students’ Portfolios Of Making Electronic Textiles, Debora Lui, Justice T. Walker, Sheri Hanna, Yasmin B. Kafai, Deborah A. Fields, Gayithri Jayathirtha

Portfolios have recently gained traction within computer science education as a way to assess students’ computational thinking and practices. Whereas traditional assessments such as exams tend to capture learning within artificial settings at a single point in time, portfolios provide more authentic opportunities to document a trajectory of students’ learning and practices in everyday contexts. Furthermore, because communication itself has been defined as an important computational thinking practice, portfolios give students a place to practice this skill in the classroom. In this study, we report on the implementation of a digital portfolio with a class of 21 high school students …

Connecting With Computer Science: Electronic Textile Portfolios As Ideational Identity Resources For High School Students, Mia S. Shaw, Deborah A. Fields, Yasmin B. Kafai

The development of student identities—their interests in computer science, perceptions of the discipline, and sense of belonging in the field—is critical for broadening participation of underrepresented groups in computing. This paper reports on the design of portfolios in which two classes of high school students reflected on the process of making electronic textile projects. We examine how students expressed self-authorship in relation to computer science and how the use of reflective portfolios shaped students’ perceptions of computer science. In the discussion we consider how reflective portfolios can serve as ideational resources for computer science identity construction.
