Environmental education is a theoretical course included in elementary teaching programs in Turkey. Considering the importance of the practical application of theoretical knowledge, it is asked prospective teachers enrolled in this course to make a short film to raise their future students' environmental awareness. A total of 68 prospective teachers participated in this study. Data was collected from short films, as well as the written forms completed by the participants explaining the idea behind the films. The data evaluated in terms of filming location, characters, topics, skills involved, messages conveyed and goals targeted for the audience. The results showed that the prospective teachers mostly focused on the dispersal of waste materials into the environment and importance of keeping the environment clean. In addition, the prospective teachers employed the technical skills of shooting the videos and editing footage, and presentation skills related to elaboration (narration-verbal expression), demonstration (description of tools), and exemplification. Based on the results, it is suggested that Technological Pedagogical Content Knowledge of prospective teachers on environmental education should be developed through future implementations.
