Development of a system which leads easygoing conversations to logical discussions

本研究开发了一个名为“建构性会话支持系统”（CCSS）的计算机系统，该系统通过将学生的陈述引导到其他学生的逻辑连接中，从而将“轻松”会话（YOU模式）引导到逻辑讨论（THEY模式）。学生必须选择其中一个连词句，例如，“我只是在想：“，“我有同样的想法：“，“我有不同的想法：“，（在你模式下），“我同意你，因为：“，“我不同意你，因为：“和“给我们看证据：该系统不仅支持学生在课堂上的“聊天”（非正式的、轻松的对话），而且还支持学生对目标语句的“辩论”（“赞成”和“反对”之间的逻辑讨论）。该系统被用于初中科学课，鼓励学生的对话。结果显示，该系统促进了低成就，精神萎靡的学生谁通常很少参加课堂讨论，在正常的班级参与。该系统进一步开发，使用PDA（个人数字助理）作为终端，通过它的学生可以输入报表，并看到在一个类的所有报表的整体网络配置。这一扩展进一步促进了非参与性学生参与课堂讨论，将他们的“随和”对话引导到更具建设性的讨论中。

The present study developed a computer system, called "Constructive Conversation Support System (CCSS), which leads "easygoing" conversations (in YOU-mode) to logical discussions (in THEY-mode) by channeling students' statements to other students in logical connections indicated by labeled link in a network shown in the display. Students must select one of the conjunctional sentences, such as, "I am just thinking : ", "I have the same idea : ", "I have a different idea : ", (in YOU-mode), "I agree with you, because : ", "I don't agree with you, because : " and "Show us the evidence : " (in THEY-mode), and so on. The system not only supports students' "chatting" (informal, easygoing conversation) in classroom, but also "debating" (logical discussions between "pros" and "cons") over a target statement. The system was used in Science class in a junior high school, encouraging students' conversations. Results show that the system facilitated the participation of low-achievement, spiritless students who usually seldom join classroom discussions in regular classes. The system is further developed to use PDA (Personal Digital Assistant) as an terminal through which students can input statements and see the overall network configurations of all the statements in a class. This extension further facilitates non-participatory students to participate in classroom discussions by leading their "easygoing" conversations to more constructive discussions.
