Abstract: A considerable number of Internet-based computer supported collaborative learning (CSCL) environments have been or are currently being developed. This paper aims to a) assure the basic collaborative conditions of learning processes; b) ease the collaborative overhead of knowledge-building communities; c) reduce the limiting structure of the CSCL environments while retaining the information needed. Based on the personal concept maps, individual students discuss potential collaborations; the information of the collaborative learning is retained while the students’ efforts are presented in a meaningful context. A heterogeneous agent approach is proposed to help students cope with large amounts of information. One possible advantage of the proposed agent approach is minimizing the likelihood of superfluous or redundant effort, which is beneficial in terms of both collaborative learning and the formation of knowledge-building communities.
