Peer Help for Problem-Based Learning

This paper describes the I-Help peer help network, where helpers and helpees are paired according to the contents of their user models. Although originally designed for large groups, in this paper we suggest ways in which I-Help may be used in a small group, problem-based learning curriculum. The use of I-Help will be very different in this context: it is not expected to be necessary for all students. However, some learners may experience difficulties with some aspects of problem-based learning, such as: scheduling of meetings; involvement in discussions; understanding roles; acquiring skills for problem-based learning; different interaction preferences; differences in cognitive styles. We describe how I-Help may be used to alleviate some of these difficulties, in particular: by putting groups into contact with other groups; or putting individuals into contact with someone outside their group who can advise, or who is facing similar problems, and would like to explore the issues jointly. At the same time, group cohesion is not disrupted.
