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，在这个环境中，学习者小组在软件代理的协助下，制定出他们认为有助于解决相关问题的计划，并将其传授给另一个知识不足的代理。协作学习平台被实现为一个服务器进程，支持学习者通过网络进行协作工作和通信，并作为服务器的后端进程，正在实施一名助教代理和一名配偶代理。 TA 代理拥有一系列问题类型，并向学习者提供解释，以及每个问题类型的计划列表以及如何使用基本知识单元。学习者组通过客户端流程运行的 HCI，在TA Agent的建议和指导下，根据TA Agent提供的知识协作制定计划并将其提供给Mate Agent，尝试解决与Mate Agent交互中的问题，而Mate Agent则可以。利用该过程实现了边教边学的隐喻。为了支持不同问题解决计划的差异化使用的有效习得，我们研究了这样的假设：这种习得仅发生。通过比较和对比不同的问题解决情节，为了验证电路理论领域的假设，实施了一个系统，其中解决方案的问题数据库按计划和子计划进行索引，学习者可以检索问题解决情节。共同/不同的计划。进行的实验与电子工程课程的学生一起发现，只有当允许学习者通过共同的规划窗口观察多个解决方案片段时，才会发生习得。
