Development of the groupware for mobile computer supported collaborative learning.

本研究旨在建构不限制儿童活动领域的移动电脑支援的合作学习环境。开发了由next元素组成的学校教育群件原型系统。由个人数字助理运行的学校教育群件客户端程序。移动在WindowsNT服务器上的学校教育群件的服务器程序。使用2.4GHz频段无线电波的IEEE802.11无线局域网。小学的孩子和老师在课堂上使用了原型程序，并进行了现场测试。结果证明了下面两个事实。在无线局域网中，与有线局域网不同，在不利的条件下，数据传输可能会失败。有必要改进程序，以便即使在这种情况下数据也不会消失。由个人数字助理运行的客户端程序具有简单有效的用户界面，即使是小学生也可以简单有效地使用。开发反馈了上述结果，并对程序进行了改进。然而，它不能充分地完成程序的现场测试。

The purpose of this study was to construct mobile computer supported collaborative learning environment which does not restrict field of activity of the children. The prototype system of the groupware for school education composed of next element was developed.1. The client program of the groupware for school education which runs by the Personal Digital Assistant.2. The server program of the groupware for school education which moves in the WindowsNT server.3. Wireless LAN of IEEE802.11 using the 2.4GHz band radio wave.Children and teacher of the elementary school used the prototype program in the class, and the field test was carried out. As the result, next two fact was proven.1. In wireless LAN unlike the wired LAN, it may fail in the transfer of the data in case of the adverse condition. It is necessary to improve the program so that the data may not disappear even in such case.2. Client program which runs by the Personal Digital Assistant has the user interface that it can be simply used efficiently even in primary school child.The development fed back the above result, and the program was improved. However, it could not be sufficiently done to the field test of the program.
