"Learning Recorder" that Helps Lesson Study of Collaborative Learning

Renovation of education requires students to engage in a newer style of learning, or collaborative learning and teachers to implement lesson study of that learning. Such learning, however, creates a situation wherein multiple student groups simultaneously engage in dialogues in a noisy classroom. Thus, we developed a “Learning Recorder” system, which has a 360-degree video camera to record students when set in the center of the group, and sends the voice data to an Automatic Speech Recognition system for immediate transcription. This paper explains how this system has evolved from our practical experiences with AI-powered lesson study and how it helped even a novice teacher look back and learn from the student dialogue. We propose that an information appliance like the Learning Recorder draws teachers’ attention to student learning, solicits multiple interpretations, and brings about collaborative learning among teachers. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
