InVis: An EDM Tool For Graphical Rendering And Analysis Of Student Interaction Data

InVis is a novel visualization tool that was developed to explore, navigate and catalog student interaction data. InVis processes datasets collected from interactive educational systems such as intelligent tutoring systems and homework helpers and visualizes the student data as graphs. This visual representation of data provides an interactive environment with additional insights into the dataset and thus enhances our understanding of students’ learning activities. Here, we demonstrate the issues encountered during the analysis of large EDM data sets, the progressive features offered by the InVis tool in order to address these issues and finally establish the effectiveness of the tool with suitable examples.
