InVis: An Interactive Visualization Tool for Exploring Interaction Networks.
Matthew W. Johnson, Michael John Eagle, Tiffany M. Barnes · 2013
We introduce InVis, a novel visualization technique and tool for exploring, navigating, and understanding user interaction data. In-Vis creates a interaction network from student-interaction data ex-tracted from large numbers of students using educational systems, and enables instructors to make new insights and discoveries about student learning. Here we present our novel interaction network model and InVis tool. We also demonstrate that InVis is an effective tool for providing instructors with useful and meaningful insights to how students solve problems. 1.
