In the university forest of Tokyo in Chichibu, two video recording robot cameras for forests (hereinafter “robot camera”) with stereophonic microphones are recording forest images and acoustic data on a daily basis. We believe that these video data, which include movies and sound recordings, can be used for making a new learning environment for children that will help them to feel the forest phenology intuitively. In this study, which targeted an audience at or older than the third grade in primary schools, we aimed to make a prototype multimedia resource for environmental education. We used video data from 6th January 2003 to 5th January 2004 from our video data archives and digitalized them. The media we produced were; i) printed cards, where one card expresses one climatic season, and its associated PDF file, ii) the DVD, which consists of the climatic seasonal chapter and temperature graphs with natural sounds, and iii) the website from which the audience can download the PDF and DVD files and which includes further information about the robot cameras. We introduced the Japanese traditional seasonal expression as a calendar, which contains 24 seasonal periods and 72 climatic seasons. The 24 seasonal periods and 72 climatic seasons are effective when organizing forest transition images ; therefore we produced the printed calendar and the DVD following these traditional seasonal units. In the printed calendar, one card represents one climatic season. One chapter on the DVD corresponded to one climatic season and each chapter has daily video images and sounds with temperature graphs associated with this period. Additionally, we built the website as a complement to the calendar and the DVD. Here children can also easily learn about robot cameras as well as downloading all the contents of the calendar in PDF format and the DVD. Consequently, we examined the effective design of these multimedia resources through the process of making a prototype. For example, there are useful techniques such as watching the DVD while using the printed calendar cards as an index of contents or for checking more details about the calendar contents while watching and listening to the DVD. It is necessary for each set of contents to be designed in a complementary way. In the future, it is expected to use this prototype with collaboration of schools so that we can evaluate with school teachers if it is a useful resource for environmental education.東京大学秩父演習林では,1995年より2台の森林映像記録ロボットカメラによる森林景観のビデオ記録が続けられている。定点定時の記録動画と音声は,森林の日々の様子を直感的に感ずることのできる環境学習コンテンツになると考えた。本研究では,小学校の総合学習において,環境教育の映像教材を利用する可能性のある3年生以上の小学生を視聴者と想定し,2003年1月6日から2004年1月5日の1年間の森林映像データと気象データをデジタル化し,24節季72候の暦に従って,候単位で映像記録をとりまとめたデジタルコンテンツを試作した。メディアは,1候を1枚のカードにレイアウトデザインした印刷物とPDFファイル,1候を1チャプターとして日々の映像と音声,及び気温の時間変化グラフを視聴できるビデオ再生画面レイアウトをデザインしたDVDを作成した。またPDFファイルとDVDファイルをダウンロードできるWeb サイトには,森林映像記録ロボットカメラについて視聴者に理解できるように平易な文章で解説を掲載し,デジタルコンテンツを配信できるようにした。試作を通じて,印刷物とDVDを一緒に視聴することで,印刷物を見ながらDVDで映像を選択して視聴する方法や,逆にDVD映像を見ながらその前後をカードで一覧するなどの使い方があることが分かった。森林の日々の様子を擬似的にでも感じる際に,印刷物とDVDとが相互に補完するメディアとしてデザインすることが必要だと思われる。本研究での試作を通じて明らかになったデザインを踏まえ,さらに洗練したデジタルコンテンツを新たに制作し,森林環境の変化を子供達が感じ取れるデジタルコンテンツの評価実験を小学校の教員との共同で進めたい
