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.

旨在建立一个终身学习环境，以协助学习者分享目标在广阔的区域网络上进行协作的学习者，允许以下4个目标，并获得结果，如概述：（1）为了使学习者与相同或不同类别的知识和案例进行比较，我们提出了拟议的和原型来促进或原型的信息，以促进教师和学习的范围，以征服教师和学位，以征服教师和学习者的范围，以构成信息，以构成信息，以构成信息，以构建信息，以构成信息，以构建信息作为成立的人，讲师指定的问题的曲目。另一方面，该系统创建了一个图表，代表知识单位之间资源中关系的外观。该地图可以通过注释来帮助学习者检索资源，解释和示例相同知识单位的使用或在不同情况下使用不同知识单位的使用差异。注释系统应用于帮助学习……更多的日语作为第二语言和地理媒体系统应用于地理的股票系统。（2）作为协助老年人与媒体代表性的学习材料进行互动的一个例子，我们开发了一种软件系统，可以使图标指向操作更容易且更快。我们将开发一个可以识别书面对象的笔迹输入系统。（3）为了帮助学习者解决问题的任务，我们为巩固问题类型的基本概念与从那里得出的知识单位有关。通过协助作者轻松地描述解决方案计划中的问题类型的使用，可以仔细研究域的可伸缩性。另一方面，开发了算法，以协助学习者进行计划和重做。（4）电子工作场所是原型的，一组学习者可以与讨论进行协作以执行上述任务。设计基于字符的流方案，使过程远程调用其他流程的方法，我们可以实现服务器多客户系统，其中将消息或字符串编码的方法从服务器给予的客户端批准的客户端传递给所有客户端，并解释了用于执行的编码方法。较少的
