Collaborative Learning Support System for Discussing Presentation Skill Based on Presentation Slide

我们的研究目的是提出获得主题解释技能的学习方法，并开发支持学习方法的工具。我们提出的学习方法包括三个步骤：1)作者利用幻灯片在观众面前展示自己的想法，2)每个观众修改幻灯片作为他们的修改，3)作者和观众讨论在他们的修改中安排主题和排序主题的原因。为了便于第二步修正的生成，提供了幻灯片重建工具。在步骤3中，还开发了讨论导航工具，以支持作者和受众之间的有效讨论。实验表明，我们的学习方法和辅助工具在引导讨论方面是有效的。

The objective of our research is to propose the learning method for obtaining the topic explanation skill and develop support tools for the learning method. We have proposed the learning method which consists of 3 steps: 1) author presents his/her ideas using the slide in front of the audience, 2) each audiences modify the slide as their amendments, 3) author and audiences discuss the reasons for arranging topics and ordering topics in their amendments. For the purpose of supporting the generation of amendments easily in step 2, slide reconstruction tool is provided. Discussion navigation tool is also developed for supporting effective discussion among author and audiences in step 3. Based on the experiment, our learning method and supporting tools were effective in navigating discussion.
