Abstract
Collaborative learning is one of the effective learning methods because the learner is led to deep understanding and to nature broad views and the creative skill. These effects are due to the interaction of the member of the group like the discussion etc. Therefore, it is important to offer a collaborative environment where such interactions occur easily. We are developing a collaborative learning support system. The system provides the knowledge data base and the function of the web forum. The knowledge data base used CmapTools to show knowledge visually. To put a mathematical symbol and figure easily on CmapTools and web forum, we devised the system by use of mimeTeX.
