This case study investigated whether teachers could improve cooperative learning of physical education lessons through the development and trial use of a video annotation system. The study also sought to shed light on how the video annotation system was perceived by the target teachers. Use of a video annotation system was found to increase the awareness of the teachers, leading to concrete improvements in their instruction. The results of this study suggest the possibility of perceiving the teaching materials, objectives, content, students, and the setting as an integral whole. Video annotation also enabled the teachers to grasp the difference in difficulty between clarifying concrete teaching problems and actually improving those problems to achieve results in daily classes.
