What does engagement actually mean?
If a teacher is talking, and all the students are looking at them and seem to be listening, presumably they are engaged.
Also, if students are writing, the room is silent, and the ones who aren’t writing are clearly thinking about what to write, presumably they are engaged.
Does engagement really just mean, on task? Is it just another way of saying, ‘The students were all doing what they were told, to the best of their ability?’
If that’s the case, then it seems to me that a good, or ‘Good’ school, should have this as a minimum expectation.*
*And sorry, I do feel that the way to get near 100% of students doing this all the time is to give sanctions when they pen tap or look out of the window.
