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 …

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 …
