Developing Virtual Tutors for online PBL Discussion Board Using Concept Map Scoring

Abstract

With the development of the information technology, digital learning is introduced to construct problem-based learning systems, such as online discussion. This paper investigated on-line PBL processes and designed intelligent tutors with pragmatics and semantic concept map. The tutors interact with students based on the observed concept map and provide guidelines for students’ on-line discussion. A preliminary experiment is carried out to exam the system implementation. The result shows the effectiveness of the proposed method and the possibilities of sharing the burden of instructors for online discussion.
