Outline of Final Research Achievements	The purpose of this study is to develop and evaluate a system for teachers to collaboratively engage in class research and analysis at schools. In this study, we developed a system that, in addition to recording classroom speech, visualizes and displays the amount of speech by the teacher and students, the position of the first occurrence of the focus word, the tendency of the appearance of the focus word, and the breakdown of the classroom scene (segmentation) based on this information. We also developed a prototype version of a method that uses images from a spy camera (a video camera worn next to the eyes) attached to the teacher to obtain the teacher's position in the classroom, and then displays the results of what the teacher is doing at that moment (speaking, writing, listening, or other).

Academic Significance and Societal Importance of the Research Achievements	本研究は、発言記録をもとに授業を構造的に解明する点に意味がある。これにより、教師が鍵となる語の初出を発言した人、全体的な発言のバランス、意識的・無意識的な教師の行動などを手がかりに振り返ることが可能になる。とくに子どもの発言を再確認することで、発言内容はもちろん、発言の背景や理由を考える契機を教師に与えることができる。授業研究は教師一人でするには困難な点もあるが、学校全体で協働することで文字起こしや討議を、印象論ではなく、同じデータ・結果を見ながら話すことができる。
