Using the LENA in teacher training: Promoting student involvement through automated feedback
Abstract and Figures
As part of professional development training for mathematic teachers, we used a speech recognition recorder (Language ENvironment Analysis, LENA) to create an automated teacher feedback system to help teachers monitor and limit the time they talk and to increase students’ active participation in mathematics lessons. Teachers got feedback with a 12h turnaround which allowed them to see how much they and their students talked on a daily basis. In this study, we wanted to know whether a) the system indicated change in the talk pattern, b) whether more complex indicators can be developed that are useful for professional development. Based on a pilot study we were able to implement an automated feedback of quality discussion episodes which was effective in increasing the amount of teacher-student discussion.
