This study aimed to examine the effects of educational films on the second-grade elementary school teacher candidates' attitudes and awareness towards environmental problems. In this study, two pre-existing groups were randomly assigned to experimental and control groups, so the study was designed according to the pre-test post-test control group quasi-experimental design. Participants from whom data were gathered were identified through purposive sampling. The awareness scale towards environmental problems and the attitude scale towards environmental problems were used as data collection tools in the study. According to the results there was a significant difference between the awareness scale mean post-test scores in favor of the experimental group. Also, the attitude scale mean post-test scores of the teacher candidates were compared and there was no difference between the attitudes mean scores of the teacher candidates.
