The study on visualization systems for computer-supported collaborative learning

In this study, we developed a Visualization tool that shows learners' interactive activities graphically during computer-supported collaborative learning (CSCL). The tool helps teachers to monitor and evaluate the interaction activities among Students, and thus it makes it easier to develop more effective instructional design for CSCL. For experiments, we used a web-based discussion group of 112 students. We investigated the effects of visualization of interactions on web discussion CSCL. Also, in lesson practice with this tool, we verified the effects through questionnaire and interviews. Our result show that the visualization tool provides a teacher with patterns of collaborative activities very clearly and insights of how to promote Students' interactions more efficiently.
