The first thing that struck me was that they worked exclusively with the textbook in class. But of course I don't see anything wrong with that. Another thing that surprised me was that the teacher doesn't sing with the children at all, she just accompanies them. When students sing, he checks that they do not sing too loud and that they follow all the pauses and onset.
