Automated Assessment of Students’ Conceptual Understanding: Supporting Students and Teachers Using Data from an Interactive Textbook

摘要

Online, interactive textbooks utilizing multimedia are continually gaining popularity in computer science courses. We present a system for automated analysis that can harness the power of these textbook and practice systems to provide information about high-level conceptual understanding to educators. The system presents a visualization using data logged by an interactive textbook to provide numeric estimates of a student's knowledge of course concepts. This information can be used to support teachers and individual students. The basis of our system is a Concept Graph, an artifact representing the concepts to be taught during the course, and their interrelations. We describe the manner in which our system uses these Concept Graphs to provide useful information to educators and students.
