I have probably already understood why the teacher is so measured, strict and still admonishes the pupils and does not even let them flap. It is a protection against indiscipline, the disintegration of the clock, chaos. But I don't want to do it this way. I think it is possible to maintain discipline, even if we let the pupils create, express themselves on the topic, when we involve activities, games, etc. in the teaching.
