The influence on the thought process of children through the environment learning program on the river using benthic invertebrate

An environmental learning program for fourth grader was carried out using benthic invertebrate in three spots of Asuka River. We analyzed the changes of class level and individual reaction level using 20 children's composition data. As a result, it was found that the class level has advanced reaction level from interest to understanding, from understanding to thinking as a whole. According to an analysis of the children’s reaction level individually, 8 children reach thinking, 18 children reach understanding, certain effects of this learning program are seen, and understanding of "relationship of space and creatures" was shown to be possible even in the development stage of fourth grader.
