Interactive Stratified Attribute Tracking Diagram for Learning Analytics

Abstract

Interactive Stratified Attribute Tracking Diagram (iSAT) is a data visualization and tool to assist interactive visual analytics of multi-attribute learning dataset. The present work reports the evolution of this diagram through a design based research methodology following its three design iterations. There are two output at the current stage i) iSAT and its Web-based interaction. ii) A Learning Analytics method suitable for both researchers and practitioners to trace student attribute value. We received satisfactory user testing score for Pre-test and post-test marks visualization through a two-phase iSAT.
