Teachers are NOT all knowing anyway. But a teacher who promotes an atmosphere of trust and open-mindedness invites students to engage in an inquiry-based classroom. He also learns along the way, identifies his own misconception and works together with the students in rediscovering knowledge through heuristics. Such happened to me during the semester 1 this school year. As a generalist, I discovered that students developed a kind of confidence to take charge of their own learning when the teacher seemed to or appeared to know less of a certain relevant question that surfaced during a class discussion. And there is also one incident when I learned a lesson from a student which I would not probably forget throughout life in doing a laboratory activity.
