How Can We Form Eeective Collaborative Learning Groups? | T H E Oretical Justiication of \opportunistic Group Formation" with Ontological Engineering |

Our research objectives include constructing a collaborative learning support system that detects appropriate situation for a learner to join in a collaborative learning session, and forms a collaborative learning group appropriate for the situation dynamically. In this paper, we describe a system of concepts concerning learning goals expected to attain by learners through collaborative learning process with justi cation by the learning theories. With the ontology, it will be possible to compare and synthesize the learning theories to design the collaborative learning
