I agree entirely. I'd also say that in a large school you will have teachers who use the system more than others. And some will be using it to cover their own weaknesses in teaching/behaviour management. However this is normal and nothing about that will change, so no point fretting/sulking about it. Newer teachers won't be so used to the old regime of total chaos in the classroom and so probably do use the room more. Good for them for having high ideals about how things will be in their classroom.
