授業映像への手書きアノテーションによるピア・レビューシステム

摘要

To improve lectures in elementary and secondary education, it is common practice that a few evaluators observe a lecture, and then have their observations discussed in meetings. While we can expect similar practice to improve lectures in higher education, it is difficult to schedule for all participants to come together, due to various reasons, for both lectures and meetings. In this paper, we propose a peer-reviewing system, which allows the users to add handwritten annotations on video images, both during recording or at a later time. This way, peer review of lectures can be done flexibly. Evaluation studies, conducted in undergraduate and graduate courses, indicated that recorded movies with annotations promoted meaningful discussion and collaboration between teachers and staffs for faculty development.%初等および中等教育では，授業観察により，授業を改善するための情報共有と議論が行われている．高等教育においても，授業観察の教育効果が期待されるが，特定の時間に観察者全員が出席して授業観察し，議論する場を設けることは難しい．そこで，授業風景をその場で収録しながら，もしくは後日再生しながら手書きでアノテーションを加えることにより，柔軟にピア・レビューを行えるシステムを開発した．大学院および学部の授業において実際に使用した結果，動画記録とアノテーションの提示がは授業の記録や教員とFD担当者による授業後の振り返りレビューにおいて．有効に利用できるとの評価が得られた．
