项目摘要

We tried to construct a collaborative learning environment in which the learners group, in collaboration and assisted by a software agent, works out such plans as they think useful for solving the problems concerned and teaches them to another agent having insufficient knowledge. And in this process the learners are expected to get insight into the problems and construct their knowledge for problem-solving.A collaborative learning platform was implemented as a server process which supports learners' collaborative works and communication via a network. And as the backend process of the server, a Teaching Assistant agent and a mate agent is being implemented. The TA agent is possessed of a repertoire of problem types with explanations to be provided to the learners and also a list of plans for each of the problem types and how to use basic knowledge units.The learners group, via HCI run by client processes, being provided with advices and guidances by the TA agent, collaborates to work o … More ut plans based on the TA agent-provided knowledge and supply them to the mate agent, try to solve the problems in interaction with the mate agent. And the latter can makes use of the plans thereafter for solving other problems. The process realizes the learning-by-teaching metaphor.In order to support efficient acquisition of differentiated usage of different problem-solving plans, we studied a hypothesis to the effect that such an acquisition only takes place by comparing and contrasting different problem-solving episodes. For verifying the hypothesis in the field of electrical circuit theory, a system was implemented in which the database of problems with solutions is indexed by plans and subplans and the learners can retrieve problem-solving episodes with common/different plans.The carried out experiment with students in an electronics engineering course revealed that acquisition takes place only when it is allowed for the learners to observe a multiplicity of solution-episodes through common windows of planning.

我们试图构建一个协作学习环境，在该环境中，学习者小组在协作和在软件代理的协助下制定了这些计划，因为他们认为对解决有关的问题有用，并向其他知识不足的代理人教导他们。在此过程中，希望学习者能够深入了解问题，并为解决问题解决方案构建知识。协作学习平台被作为服务器流程实现，该服务的过程支持学习者通过网络的协作工作和通信。作为服务器的后端过程，正在实施助教代理和伴侣代理。 The TA agent is assumed of a repertoire of problem types with explanations to be provided to the learners and also a list of plans for each of the problem types and how to use basic knowledge units.The learners group, via HCI run by client processes, being provided with advice and guidance by the TA agent, collaborates to work o … More ut plans based on the TA agent-provided knowledge and supply them to the mate agent, try to solve the problems in interaction with the mate agent.后来可以利用该计划来解决其他问题。该过程实现了通过教学的隐喻来实现的，以支持对不同问题解决计划的差异化使用的有效收购，我们研究了一个假设，即仅通过比较和对比不同的解决问题的情节才能进行这种收购。为了验证电路理论领域中的假设，实施了一个系统，在该系统中，解决方案问题的数据库由计划和子计划索引，学习者可以检索使用常见/不同计划的问题解决问题的情节。在电子工程课程中，与学习的范围内有关，可以在学习过程中与学习者进行综合范围，以观察到综合范围的学习范围。较少的
