The purpose of this study was to determine the effectiveness of a positively-oriented instructional program in developing a positive attitude toward environmental problems in selected preservice elementary teachers. In order to more accurately discern factors involved in attitude change the number of subjects was limited to three and a descriptive approach was utilized. It was anticipated that this approach might lead to the generation of hypotheses concerning the alteration of environmental attitudes. Analysis of the test instruments permitted the following conclusions: participation in the program was effective in developing positive environmental attitudes and the subjects displayed a change in or reinforcement of attitude toward specific environmental issues. In addition, it was implied from data collected that (1) environmental materials utilized were effective in producing a positive attitude, (2) active participation aided in the development of a positive attitude, (3) the subjects displayed a greater comprehension of ecological principles, and (4) the students in the subjects' classes were influential in causing attitude change. Recommendations derived from the study are also included. (Author/BL)
