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 …
