EDM Vis

We built EDM Vis, a software tool for visualizing student problem-solving in learning environments such as computer-aided instruction (CAI) or intelligent tutoring systems (ITS). EDM Vis can be used by educational researchers, instructional designers, and educators to better understand student learning. EDM Vis can help educators understand student learning because it displays how students have progressed through procedural problems in either an ITS or CAI tool. Problems are discretized into states, with the initial parameters described by the problem as the starting state. Consecutive states are obtained based on the actions students have performed in an ITS or CAI tool. Educators can use the tool to explore and discover information regarding student progress. This talk will address some of the design issues and considerations we have made and open up to the audience to provide thoughtful feedback to improve the quality of another great UNC Charlotte visualization tool
