A Study of the BBS Communities which Assist Practice Classes by Using Network Analysis

Abstract

We proposed the bulletin board system which assists classes with practices. Our system does not obstruct communication among students so that they can utter their opinions freely. Our system extracts useful information and provides them to students to dissolve their questions. We managed our system in the information education classes. But in some classes, students rarely used our system and there were few utterances. We thought that it was necessary to find out the features of the community on the bulletin board system and to mange the system effectively. So we focus on the relationship between users and topics and visualize the community on the bulletin board system by the network analysis. We analyze the features of the visualized communities. We find out that there are some factors such as acknowledgment among users, students who utter positively and teacher’s role to promote them to utter.
