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

本研究以同一水系中的“流域”为研究对象。研究了流域内各地的物理、化学、生物和地质等环境因素，以制定教材和活动方案。在黑泽河流域(广岛县)取得了以下成果：(1)收集了有关黑泽河流域的基础资料。的水生动物种类得到了认可。根据黑泽河流域的基础数据设计了水环境研究的学习方案，并在该流域的两所学校进行了实践活动的尝试。在上述研究结果的基础上，构建了水环境地图网页。(4)根据试行活动的结果，对活动内容进行了评估和改进。合作学校是从黑泽河流域培育而来的，并选出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，通过交流两所学校的信息，实现了基于更广泛观点的讨论。然而，为了利用互联网作为信息交流的媒介，在这一领域的一些学校，环境方面的考虑是不完整的。

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.
