We discuss how a system to support the facilitation efforts of inexperienced case leaders can be brought close to reality. We begin by considering methods to support facilitation efforts directed at novices. For this purpose, we conduct two tests. Using the test results, we propose that as one capability of a support system, the system should include some mechanism for recommending participants found by pretesting to already have a high level of knowledge, and that such recommended participants be given particular encouragement by the facilitator to externalize their discoveries. Also, the system should include some mechanism for recommending how to split up group members based on pretest results. By this mechanism, we can provide each group with a good balance of participant skill levels, including participants with a high skill level, and such an arrangement should encourage the groups in learning occurrence by letting them discover a new viewpoint.
