In the U.S. we force children to sit still through hours of classes, wonder why they get distracted, and then medicate them. In other countries kids get more breaks to expend energy and are then more attentive - e.g., http://www.theatlantic.com/education/archive/2014/06/how-fin... "In every one of the experiments, students were more attentive after a break than before a break. They also found that the children were less attentive when the timing of the break was delayed—or in other words, when the lesson dragged on."
