在本文中，基于基于练习的课程中伴随小组作业的课后作业是在在线线程公告板系统上完成的假设，作者提出了一种为教师提供支持的工具。具体来说，作者在关注构成在线公告板上讨论的因素、发表评论的用户、主题和要讨论的项目（关键词）的同时，尝试将这些因素之间的关系可视化为网络图。作者还提出了评论度和激活度的指标来评估那里形成的社区。我们的实验表明，使用所提出的工具实际实施小组工作表明，网络图和评估指标的使用有助于区分那些进行正常讨论的小组和那些没有进行此类讨论的小组之间的差异。作者证实，这可以使教师轻松发现那些不参与讨论的学生和讨论迟缓的小组。
In this paper, based on the assumption that after-class work in an exercise-based course accompanied by group work is done on an online threaded bulletin board system, the authors propose a support tool for the instructors. Specifically, while focusing on the factors that compose a discussion on the online bulletin board, the users who comment, the topics, and the items (keywords) to be discussed, the authors try to visualize the relationships among these factors as network diagrams. The authors also propose indexes, the comment degree and the activation degree, to evaluate communities formed there. Our experiments in which group work was actually implemented with the application of the proposed tool demonstrated that use of the network diagrams and the evaluation indexes served to distinguish the differences between those groups with properly-proceeding discussions and those without such discussions. The authors confirmed that this can enable the instructors to easily discover those students who do not participate in the discussion and groups with sluggish discussions.
