Where science teachers instruct their students about environmental matters, it is very important to consider how students acquire environmental cognition. In this study, two methods were adopted to facilitate the learning process : a control class using VTR teaching materials for instruction and an experimental class using hands-on experiments. The objective of this study was to measure the effect of experimental methods on students' learning process. To analyze the effects of such instruction, the "Hierarchical Graph Method" was employed. In order to estimate the impact of experimental instruction and the effect of audio-visual instruction, we defined the lack of change in students' cognition as "the rate of nonchange". Within this framework, the following facts were discovered : 1) The environmental cognition of the groups undergoing experimental instruction changed more than the control groups. 2) According to the results of the Hierarchical Graph Method, the experimental groups were able to relate the process of environmental pollution to the phenomenon of "the circulation of matter". 3) The Hierarchical Graph Method indicated that the experimental groups had acquired both "wide" and "deep" environmental cognition. 4) It became clear from the results of the Hierarchical Graph Method and the "rate of nonchange" that the experimental and interactive instruction aided the acquisition of environmental cognition. 5) The Hierarchical Graph Method provided clear visual cues which enabled us to estimate easily the merits of experimental instruction on the formation of environmental cognition.
