Educational Data Mining Visualization: Watching Students Learn


EDM Vis is a visualization software tool for visualizing log-data from either intelligent tutoring systems, computer aided instructional tools, or even digital games. As a person uses one of the above softwares, typically the user’s interactions are logged, and EDM Vis is used to read those logs and visualize the behavior a person has demonstrated within one of those tools.

EDM Vis was originally designed for visualizing data from the logic domain, with the main contributor of log-data coming from a logic tutor Dr. Barnes had developed during her doctoral research, and is still used today. However EDM Vis has also been used to visualize data gathered from Marvin Croy‘s Deep Thought Logic Tutor as well.


Below are some screen shots of EDM Vis during various stages of its development.
