Study on Evaluation of School Network Environments

为科普全国中小学计算机网络化的需要，规划并实施了“百校联网工程”等多项研究。虽然这些项目积累了各种实际的研究结果，但它们不能提出替代性的教育政策。也就是说，他们没有收集足够的基础数据，在全国范围内引进计算机网络在日本的学校，也没有找到和评估一个现实的解决方案，在各个方面，如技术，成本，制度，教师的素养。在本研究中，我们开发并评估了一些解决方案，分析了（a）利用各种计算机网络的教育效果，（B）Internet和学校LAN的组合，（c）与外部连接的操作团队和网络拓扑结构，（d）与外部连接时选择适当的通信模式，（e）中小学和高等教育机构在网络建设和管理方面的有效合作：首先，研究了实时多媒体通信的必要性，为了比较几种电视会议系统、ISDN直接连接、第二，为了调查中小学与高等教育机构之间的有效合作，在一所学校引进互联网时进行了参与性观察。第三，测量和分析了网络和多媒体对儿童的教育和心理影响。

To cope with the nation-wide introduction of computer network in elementary and secondary schools, several researches, such as "100 Schools Networking Project" have been planned and carried out. Although these projects accumulated various practical findings, they could not propose an alternative educational policy. That is, they did not collect sufficient basic data for the nation-wide introduction of computer network in Japanese schools, nor they found and evaluated a realistic solution in various aspects, such as technology, cost, institution, and literacy of teachers. In this study, we developed and evaluated some solutions for the goal, analyzing (a) educational effects of the utilization of various computer networks, (b) combinations of Internet and school LAN, (c) the operation team for the connection with the outside, and network topology, (d) selection of an appropriate communication mode in connecting with the outside, (e) effective cooperation between elementary/secondary schools and higher education institutions in constructing and managing the network.First, the necessity of real-time multimedia communications was examined, In order to compare their usability and effectiveness among several videoconferencing systems, ISDN direct connection, Internet connection and use of CATV network were examined.Second, in order to survey an effective cooperation between elementary/secondary schools and higher education institutions, a participatory observation was carried out when the Internet was introduced in a school. While supporting the connection with Internet, development of the school homepage, arrangements of international collaborative classrooms, the process was analyzed and some effective solutions were developedThird, educational and psychological influences of internet and multimedia on children were measured and analyzed.
