Communication support visual interface for collaborative learning

Abstract

In computer-supported collaborative learning, learners focus on particular learners/utterances in discussing exercises. However, as the communication band of information networks is restricted, learners cannot acquire much information about the situations or the behaviors of other learners in the learning environment. In this paper, we describe an interactive interface where learners are aware of the conversation flow and visually acquire information. In our interface, utterance texts are moved toward the learner view from the transition information of utterances. Focusing utterances of the learner are detected based on the target learner of utterances and stressed in the represented in the interface. Experimental results showed that participants could intuitively grasp the conversation flow by observing the moving utterances. © 2010 Springer-Verlag.
