Abstract

Current Learning Management Systems generically provide virtual places to conduct interactions between students and educators.Chats, forums and other communication mechanisms usually are present in any LMS.In this paper, we propose a tool that can be embedded in any LMS that features some sort of hierarchical communication mechanisms.The proposed system is capable of depicting and analyzing online interactions in an easy to understand social graph.The vertex positioning algorithm is based on social network analysis statistics, taken from the collected interactions, and is able to smoothly present the temporal evolution in order to find communicational patterns and report them to the educator and the students.
