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

我们使用课程管理系统(CMS)进行了自学式程序设计课程的实践，并取得了一定的教育效果。我们设计了一个包括同行评议过程的小组讨论模式，在这个过程中，学生们相互展示他们的产品(方案和报告)，评论他们的产品，并改进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，因此很难使用它来执行我们的讨论模型。我们开发的讨论板系统具有专门为小组讨论设计的一些功能。我们的小组讨论模型的步骤如下。(1)上交方案和报告，(2)相互评审其他成员的方案和报告，(3)回应评估，通过参考评论改进他们的方案，并再次讨论，(4)上交最终版本。我们已经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)上交自己的产品，(2)相互评价自己的产品。我们实现了对学生评价结果进行汇总的功能，这样教师就可以减少工作量来对学生的评价结果进行汇总。此外，我们还制作了讨论板，学生可以通过公开的名字或匿名的方式在他们的产品上进行讨论，并使其不对其他学生开放，直到他们完成评估。基于本研究开发的讨论板工具，实现了对学生评论内容自动添加评论的代理的研究，并有进一步发展的可能。

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.
