Development of Indexes to Grasp the Learnes' Activity on BBS.

Abstract

This study aims at examining what kind of indexes are applicable to grasp learners' condition of participation or tendency of learners' statement on BBS. Twelve indexes for grasping learners' condition of participation, and three indexes for grasping tendency of learners' statement are calculated automatically with a system we developed and displayed on the web browser. We calculated these indexes based on a log data of an e-learning class, and investigated their validity through questionnaire and interview. The result shows that the diversity of posted words is relatively appropriate to grasp learners' condition of participation, because it had strong correlation with assessment of learners' condition of participation by estimators who grasp the communication on BBS well. It is also implied that indexes of tendency of learners' statement are available to take a general view of discussion on BBS.
