In environmental education, the video is considered to be an effective teaching material to understand the change in the environment for a long term. However, to produce the effect really, it is necessary to use multi-year environment monitoring video. On this study, using digital archives of multi-year forest monitoring video (filmed by the Robot Camera in the university forest in Chichibu, the University of Tokyo), contents for environmental education are developed along the class idea that the teacher of the elementary school actually made. ISn the process, it is intended to clarify effectiveness of the digital archives and preferable contents for environmental education by the digital archives. As a result, it is clarified that digital archives of multi-year forest monitoring video are novel and effective in terms of becoming possible to produce contents for environmental education in response to the requests from educational sites swiftly and flexibly. And it is also clarified that contents, which emphasize video of diverse seasons (e. g. foliage season) and raise“awareness”, are preferable as contents for environmental education using the digital archives of multi-year forest monitoring video.
