Development of the Learning Environment with Multimedia Communication

本研究的目的是阐明多媒体通信，特别是利用互联网进行通信的潜力和风险，并利用多媒体通信技术开发一些学习环境。首先，我们回顾了美国和日本互联网的教育应用情况。关于日本的现状，我们对100所接入互联网的学校进行了问卷调查，并考察了这项技术引入的问题。其次，我们对电子邮件沟通对日本一所小学的儿童和教师的影响进行了长期研究。我们发现，很少有孩子会自动使用电子邮件，并观察到各种因素。再次，我们对无线局域网系统的应用进行了开发研究。美国政府现在正在规划使用5 GHz无线局域网的信息基础设施。这些都对互联网的教育使用产生了强烈的影响。为此，我们开发了无线局域网电视会议系统的测试系统，并对该系统进行了评估。
