项目摘要

This project focuses on methods to assist learners in learning by discussion through computer network. We investigated effect of exchanging information against learners' attitude towards discussion by experiments, and proposed a tool for cooperative learning that visualizes contents of discussion from different viewpoints. We also proposed a method of promoting discussion by introducing pseudo learner agents.We investigated effects of expressions of participants, effects of feedback of eye movement by a remote control camera and roles of a common work field against learners' attitudes. As a result, we found that feedback of eye movement by a monitor increases learners feeling about existence of opponents, and a common work field to share materials is important for discussion.Learning by discussion improves learner's understanding about topics by interaction with each other. During this process, learners need to grasp similarity and difference between opinions and to grasp development of discussion. Thinking about streams of discussion and causes of participants' changes of opinions etc. after the discussion is also useful to improve discussion skills. We developed a discussion tool that visualizes structure of discussion and changes of opinions etc. in order to assist these kinds of learning. We evaluated the effectiveness of the tool by experiment.We proposed a method to activate discussion by introducing pseudo leamer agents. The agent doesn't understand meanings of discussion but it gets causal relations between utterances from the discussion tool.The roles of the agent are to introduce leamers of few utterances into discussion and to pay attention to buried opinions by using these relations.

该项目的重点是通过计算机网络帮助学习者通过讨论进行学习的方法。我们通过实验研究了信息交换对学习者对讨论的态度的影响，并提出了一种合作学习工具，可以从不同的角度可视化讨论内容。我们还提出了一种通过引入伪学习者代理来促进讨论的方法。我们研究了参与者表情的影响、遥控摄像头眼动反馈的影响以及共同工作领域的角色对学习者态度的影响。结果，我们发现显示器的眼球运动反馈可以增加学习者对对手存在的感觉，并且共享材料的共同工作领域对于讨论很重要。通过讨论学习可以通过彼此的互动提高学习者对主题的理解。在这个过程中，学习者需要把握观点之间的异同，把握讨论的进展。讨论结束后思考讨论的脉络、与会者意见变化的原因等，也有助于提高讨论技巧。我们开发了一种讨论工具，可以将讨论结构和意见变化等可视化，以协助此类学习。我们通过实验评估了该工具的有效性。我们提出了一种通过引入伪学习代理来激活讨论的方法。智能体不理解讨论的含义，但它从讨论工具中获取话语之间的因果关系。智能体的作用是将少数话语的学习者引入讨论中，并利用这些关系来关注隐藏的观点。
