岡山大学大学院教育学研究科の理科教育専攻の講義として、教材開発・授業案開発をテーマとした新しい講義を試みたのでその報告を行う。本講義は、理科教育講座に所属する大学院生、理科教育講座の大学教員、附属学校の理科関係の教諭が三者協働で進めることが特徴である。課題設定、教材開発を含めた実践準備および実践を院生チームを組み遂行させ、さらに経験や専門性の異なる人材と論議を重ねて活動を進めることを通じ、将来、協働で学校現場の課題提案・解決を行うことのできる能力を養うことを目標とした。This is a report of the new type of lectures on the development of teaching plans and teaching materials attempted in the science class in the Master's Course, Okayama University. The lectures were conducted in collaboration of the graduate students and the academic staffs in the science education course, and the science teachers of the attached school of Okayama University. The graduate students were grouped into two teams of five or six people, assigned to decide on themes, prepare and practice the development of teaching plans and teaching materials. They conducted their activities discussing problems with people of different experience and specialty, thus developing the ability to jointly propose and solve problems at schools in future.
