Abstract
This research positions image media expression involving relationships and interactions with others as “image media expression based on collaborative learning.” The ultimate goal of this research is to clarify the educational effects of “image media expression based on collaborative learning” from the perspectives of students’ learning behavior, social behavior, and human development. In this article, the principle of collaboration was outlined, and some results from the practice of “Mobilemovie” for high school students and the verification of its educational effect were reported. A questionnaire survey was conducted concurrently with practice, and students’ perceptions about learning were analyzed. As a result, the four-factor structure consisting of “Endogenous learning by collaboration,” “Promotion of creative activities by inspiration from others,” “Understanding others,” and “Individual-oriented” was shown as the actual state of learning of students. The research also demonstrated that this practice caused positive and negative effects.
