Organization of solution knowledge graph from collaborative learning records

Abstract

In collaborative learning, participants generate their own answers by exchanging their opinions through a discussion. Since the discussion in a collaborative learning includes knowledge for solving an exercise, the collaborative learning record is useful for other learners who tackle the same exercise. We propose a method for organizing solution knowledge in collaborative learning records as a solution knowledge graph. In this method, utterance collections of the same answering method are extracted and structured from a viewpoint of their effectiveness based on annotations attached by participants. In addition, the structure of the solution knowledge graph is refined by learning records of self-learners who use it as knowledge for solving exercises. © 2009 Springer Berlin Heidelberg.
