Prospect for Communication-Satellite-Based Refresh Education and its Teaching Form

本研究的目的是在基于通信卫星的远程教育系统上进行实验，将面向工程师的教育计划交付给私营公司，并从学生的反馈中进行评估。1993年，在哈佛大学商学院的合作下，进行了辩论课堂实验，辩论课堂是辩论的常用手段。1994年，对实验进行了进一步评价。此外，我们还对刷新教育的信息传递系统进行了调查，得出以下结论：实际课堂由j.h eskett教授从波士顿送到东京（T.I.T.），其有效性得到了证实。提出了一种评价国际卫星通信音视频时延的新方法。对录音课堂进行分析，提炼出5个主导因素。63%的学生认为辩论课堂是一种更好的选择。针对辩论课堂的评价目的，开发了基于计算机的会话分析系统，并验证了其有效性。利用Internet链路，开发了一套适用于刷新教育的信息数据库系统。针对不同的情况，开发了两种有效的系统。

The aim of this research is to perform the experiments on communication-satellite-based distant education system, to deliver the engineer-oriented educational programs to private companies, and to make their evaluation from students'reponses.In 1993, a debate classroom experiment was made under the co-operation of Harvard University Business School where debate is commonly used. In 1994, further evaluation of the experiment was performed. In addtion, we investigated the information-delivery system for refresh education, and had the following conclusions :1. The actual classroom was delivered by Prof.J.Heskett from Boston to Tokyo (T.I.T.), and its effectiveness was confirmed.2. A new method was developed for the evaluation of audio and video delay at the international satellite commuication.3. The recorded classroom was analyzed to extract 5 dominant factors. 63 percents of students chose the debate classroom as a preferable one.4. The computer-based conversation-analysis system was developed for the evaluation purpose of the debate classroom, and its effectiveness was confirmed.5. An information detabase system suitable for refresh education was newly developed by using Internet link. Two types of system were effectively developed for different cases.
