Development of a Discussion Board Tool Designed for the Collaborative Learning that Includes Peer-Review Process

我们一直在使用课程管理系统（CMS）的自学风格的程序设计课程，我们已经报告了一些教育效果已经从这些做法。我们设计了一个小组讨论的模式，其中包括同行评议的过程中，学生展示他们的产品（程序和报告），审查他们的产品，并提高他们的产品的完美性。然而，由于CMS工具的讨论功能不具有评分功能，因此使用它来执行我们的讨论模型是非常困难的。我们开发了讨论板系统，该系统具有一些专门为小组讨论设计的功能。我们的小组讨论模型的过程如下。(1)交程序和报告，（2）互相审阅其他成员的程序和报告，（3）对评估作出回应，通过参考意见改进他们的程序，并再次讨论，（4）交最终版本。我们实现了一些功能来执行小组讨论。在讨论板系统上，学生可以：（1）提交他们的产品，（2）相互评价他们的产品。实现了学生评价结果的汇总功能，使教师可以减少汇总的工作量。此外，我们还制作了一个讨论板，学生可以通过一个揭示性的名称或匿名来讨论他们的产品，并使其不对其他学生开放，直到他们完成他们的评估。利用这些功能，可以管理各种同行评议和讨论。基于本研究开发的讨论板工具，进行了对学生的评论内容自动进行评论的Agent的研究，今后也有开发的可能性。

We have been practicing the programming course in the self-learning style using Course Management System (CMS), and we have already reported that some educational effects have been obtained from those practices. We have designed a model of a group discussion which includes peer-review process in which students show their products (programs and reports) to each other, review their products, and improve their products' perfection. However, because the discussion function of CMS tools doesn't have the grading function, it is very difficult to perform our discussion model using it. We have developed the discussion board system with some functions designed specially for the group discussion.The procedures in our group discussion model are as follows. (1) hand in programs and reports, (2) review the other members' programs and reports to each other, (3) respond to the evaluation, improve their programs by referring the comments, and discuss about them again, and (4) hand in the final version. We have implemented some functions to perform the group discussion. On the discussion board system, students can : (1) hand in their products, and (2) evaluate their products to each other. We have implemented the function to total the student's evaluation result, so that teachers can reduce their work to total them. In addition, we make discussion board that students can discuss on their product by a revealing name or by anonym it, and make it un-open to the other students until they finish their evaluations. Various peer-reviews and the discussions were able to be managed by using these functions.The research of the agent who automatically applies the comment to the content of the students' remarks are done based on the discussion board tools made in this research, and there is a possibility of developing in the future.
