3. Moving around the classroom

The basic way to walk around the class and check how they are doing

The most usual way to move around the classroom is that you walk between the student's desks and check their notes quickly.
I've been observing a lot of classes, but I hardly see the teacher who can do this "walking between desks" in basic ways.
If I have to choose a word, most of the teachers do really nonsense ways that are so to speak "just stroll between desks".
