That call and response is given between the teacher and their class to remind the kids that they need to behave well. This small group of kids is part of the preschool class at the carepoint in Oditel. Much of the education is done by rote learning so the teachers fall into a rhythmic delivery as they repeat things again and again. It was soothing to listen to and I can't imagine learning that way here in the states. I'd fall asleep in my chair.
