项目摘要

Aiming at developing an environment for life-long learning to assist learners who share goals to learn collaboratively on wide-area networks, the following 4 objectives were persued and results were obtained as outlined:(1)In order to make learners compare knowledge and cases of the same or different categories, we proposed and prototyped a system which assists teachers and learners to annotate such positions of information resources as explaining or exemplifying use of knowledge units necessary in solving problems as well as those founding them, the repertoire of the problems being specified by the instructor. The system, on the other hand, creates a map representing the appearances of relationships in the resources between the knowledge units. The map helps learners retrieve resources, via annotations, explaining and exemplifying differences in usage of the same knowledge units or use of different knowledge units in different situations. Annotation system applied to assisting learnin … More g Japanese as the second language and a map system applied to our Share Media system in geography both turned out effective.(2)As an example of assisting the aged people in interacting with media-represented learning materials, we developed a software system for making icon pointing operation easier and faster. We are to develop a handwriting input system that can recognize written objects.(3)As for assistance of learners' problem-solving tasks, we worked for consolidating fundamental concepts of problem types in relation to knowledge units derived therefrom. And domain scalability was perused by assisting the authors easily to describe use of problem types in the solution plans for specific problems. On the other hand, algorithms were developed for assisting the learners in planning as well as redoing.(4)An electronic workplace was prototyped where a group of learners can collaborate with discussion to carry out such tasks as mentioned above. Devising a character-based streaming scheme enabling a process remotely to invoke methods of other processes, we could realize a server multi-client system in which a message or a string-coded method from a client given approval by the server is delivered to all of the clients, the coded method being interpreted for execution.

针对终身学习的环境，帮助有共同目标的学习者在广域网络上协作学习，追求了以下4个目标，并取得了如下结果：(1)为了让学习者将发展中的知识与案例进行比较针对相同或不同类别的问题，我们提出并原型化了一个系统，该系统可以帮助教师和学习者注释信息资源的位置，例如解释或举例说明解决问题所需的知识单元以及发现问题的知识单元、问题的全部内容另一方面，系统创建一个表示知识单元之间资源关系的地图，该地图通过注释帮助学习者检索资源，解释和举例说明相同知识的使用差异。用于辅助学习日语作为第二语言的注释系统和应用于地理共享媒体系统的地图系统都非常有效。（2）作为辅助学习的示例。与老年人交往时媒体代表的学习材料，我们开发了一个软件系统，使图标指向操作更容易和更快。我们将开发一个可以识别书写对象的手写输入系统。（3）在帮助学习者解决问题的任务方面，我们进行了工作。用于巩固与由此派生的知识单元相关的问题类型的基本概念，并通过帮助作者轻松地描述特定问题的解决方案中问题类型的使用来仔细研究领域可扩展性。学习者在规划以及(4)建立了一个电子工作场所的原型，其中一组学习者可以协作讨论来执行上述任务，设计一个基于字符的流方案，使一个进程能够远程调用其他进程的方法，我们可以实现一个。服务器多客户端系统，其中来自服务器批准的客户端的消息或字符串编码方法被传递到所有客户端，编码方法被解释为执行。
