Purpose: "In this paper, we present a generic CT assessment scheme and propose metrics for evaluating correctness of computational and domain-specific constructs in computational models that students construct in CTSiM – a learning environment that combines CT with middle school science. We report a teacher-led, multi-domain classroom study using CTSiM and use our metrics to study how students’ model evolution relates to their pre-post learning gains."
Findings: "The intervention produced significant learning gains overall, and for both domains and CT skills, measured separately . All learning gains were significant at the p<0.0001 level and effect sizes were high (in the range of 0.4-0.7)."
Recommendations: "Our results lay the framework for online evaluation and scaffolding of students in CTSiM."
