Estimating the Local Size and Coverage of Interaction Network Regions

International Educational Data Mining Society, Paper presented at the International Conference on Educational Data Mining (EDM) (8th, Madrid, Spain, Jun 26-29, 2015)
Interactive problem solving environments, such as intelligent tutoring systems and educational video games, produce large amounts of transactional data which make it a challenge for both researchers and educators to understand how students work within the environment. Researchers have modeled the student-tutor interactions using complex network representations to automatically derive next-step hints, derive high-level approaches, and create visualizations of student behavior. However, students do not explore the complete problem space. The nonuniform exploration of the problem results in smaller networks and less next-step hints. In this work we explore the possibility of using frequency estimation to uncover locations in the network with differing amounts of student-saturation. Identification of these regions can be used to locate specific problem approaches and strategies that would be most improved by additional student-data. [For complete proceedings, see ED560503.]
