The assessment of mobile computational thinking

This paper introduces a rubric for analyzing \"mobile computational thinking\" (MCT) as represented in App Inventor work products. To demonstrate its efficacy, this rubric was used to evaluate and compare student work from the CS and non-CS student cohorts in a mixed-major app design undergraduate course. Our analysis showed some significant differences between the cohorts, which were expected, as well as more subtle differences. The rubric demonstrated that it was sensitive to significant and subtle variations of MCT. The instrument is available for download and use.
