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

我们利用课程管理系统（CMS）进行了自学式的编程课程实践，并取得了一定的教学效果。我们设计了一种小组讨论的模式，其中包括同行评审过程，学生们相互展示他们的产品（程序和报告），审查他们的产品，并改进他们的产品的完美性。但是，由于CMS工具的讨论功能没有分级功能，使用它来执行我们的讨论模型非常困难。我们开发了讨论板系统，并为小组讨论设计了一些功能。我们小组讨论模式的流程如下。(1)上交节目和报告；(2)互相审阅其他成员的节目和报告；(3)对评价作出回应，参考意见对自己的节目进行改进，并再次讨论；(4)提交最终版本。我们实现了一些功能来进行小组讨论。在讨论板系统中，学生可以：(1)提交自己的产品，(2)互相评价自己的产品。我们实现了对学生评价结果进行汇总的功能，从而减少了教师对学生评价结果进行汇总的工作量。此外，我们制作了讨论板，学生可以用公开的名字或匿名的方式讨论他们的产品，并且在其他学生完成评估之前不向其他学生开放。通过使用这些功能，可以管理各种同行评审和讨论。自动将评论应用到学生评论内容的代理的研究是基于本研究中制作的讨论板工具完成的，未来有发展的可能。

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.
