Practical Study on the River Environmental Education by School Participating Activity in the River Basin

本研究以某一水系中的“流域”为研究对象。考察了流域各地的物理、化学、生物、地质等环境因素，编制了教材和活动方案。在黑河流域（广岛县）得到了以下结果：(1)收集了黑河流域的基本资料。发现水生动物64种。收集了水质和地理特征数据。(2)基于黑河流域的基础数据，设计了水环境研究的学习方案，并进行了流域两大流派的实践活动尝试。因此，有人建议，通过修改节目内容，使其适合学校类型和学校，可以有效地开展活动。(3)基于上述结果，构建了“水环境图”网页。(4)根据尝试活动的结果，对项目内容进行评估和改进。合作学校是在黑河流域设立的，选择了一所小学和一所初中。水环境研究是由这些学校进行的。此外，通过交换双方的信息，实现了基于更广阔视野的讨论。然而，为了使用互联网作为信息交换的媒介，表明在这一地区的一些学校对环境的考虑是不完整的。

In the present study, "the river basin" in one river system was researched. The environmental factors including physical, chemical, biological and geological features of various places in the river basin were examined to develop the teaching materials and the activity programs. The following results were obtained in the Kurose river basin (Hiroshima Pref.).(1)Basic data was collected concerning the Kurose river basin. 64 kinds of the aquatic animals were recognized. The data of the water quality and the geographical features were collected.(2)The learning programs for the water environmental study were designed based on the basic data of the Kurose river basin, and practical activities were tried by two schools of the basin. As a result, it was suggested that the effective activities were possible by modifying the content of the program to be suitable for a school kind and a school.(3)Based on the above-mentioned results, the Web page "Water environmental map" was built.(4)The content of the program was evaluated and improved based on the results of tried activities. The cooperation schools were raised from the Kurose river basin, and one elementary school and one junior high school were selected. The water environmental study was carried out by these schools. Moreover, the discussion based on the wider view was achieved by exchanging information on both schools. However, in order to use the Internet as the medium of the information exchange, it was shown that environmental considerations were incomplete at some schools in this area.
