This research aimed to identify significant features of learning environment and teacher's support that facilitate students' interaction with natural surroundings. Students in my class often get enthusiastic to anything new and impressive to them but do not keep at them for long: they have never recognized the virtue of the natural surroundings, i.e. they are to them just plane or meaningless. In the class, children played with color cellophane and clay. There, three significant features of the environment and support were identified: generally speaking, to keep them interested in nature, the teacher should (1) provide his/her children with natural objects or has them get closer to and involved in nature, arising their consciousness of its virtue, (2) have them play with materials with which they can dream up their pieces they want, and (3) encourage them, at the end, to develop their plays by themselves. These features were singled out in only one practice of mine. For some more definite features, I am going to undertake a series of the same kind of researches.
