Here's a good diagram that explains the thinking behind the concept of the flipped classroom. The principle is that by using recorded lectures and examples the teacher can set the input as homework and use classroom time for practice, discussion and tutoring. In the traditional setting the pupils practice at home and when they get stuck the teacher is not there to help. Parents are not always a reliable option!
Of course this assumes that the pupils will actually watch the input at home at all. Then again the traditional set-up is not working either so it's well worth seeing if the flipped model can raise motivation.
