i was asked to video myself for forty five minutes and then fill out this score sheet, essentially fill out a classroom observation protocol on my own class. Stephen brookfield has been doing research nd what he calls the critical incident questioner for decades now. He invites students to take about five minutes to respond to questions about the most recent class. And you think about this kind of question, this series of questions, is going to help him inform his own teaching but also help the learners.
