In analyzing human psychological behavior or action, multiple-choice question methods are quite effective means. Especially the questionnaire method in accordance with the rating scale method is frequently used because of its simplicity and reliability. The structural analysis method is a mean for analyzing the consciousness structure of evaluators from ordering structure of questionnaire items, and interval rating method is considered to reflect ambiguity of evaluators' consciousness better than fixed-point rating method. In this structural analysis method, a hierarchical structure graph (hereafter just called the structure graph) of the item group is constructed in order to visualize the related structure of the item group. Then in this paper, the structural analysis method for interval rating scale data to investigate consciousness concerning the environment education/environmental problems. On the other hand by providing the evaluators with some stimulus, by performing the same consciousness survey before and after the conduct, and by computing the similarity (difference) of these structure graphs, metamorphosis of the consciousness structure of the evaluators' group have been analyzed. As a result, problematic points of the environment education or effects of video teaching aids have been verified.
