How important is homework? A vital part of a good education? Or an increasingly old fashioned and irrelevant practice? In this episode of Learning World, find out how teachers in Finland make homework a rich learning experience.Teachers start lessons by checking their homework. "This gives me the opportunity to really know what's going on inside their heads. It is a different thing from what I say in class and what I think is going on in their heads", says a teacher. The philosophy is that all learning should happen in school and that daily homework should not exceed 30 minutes. Some youngsters can do it in less. "One important thing in learning is motivation. If the workload is not overwhelming then it is fun, too much repetitive work would discourage them," says a teacher.
