One of the hottest topics in education is the flipped classroom which I have seen in use the last couple of years.
Instead of the usual teacher lecture model, students are given videos to watch at home. Most often I have seen math teachers offer this which I would have loved as a student. The best way I have seen flipped classrooms work is to give students a video one or two times a week - not as a daily lesson. It would be too much for anyone.
Khan Academy is one of the best websites for students to get some extra teaching help and anything can be searched in there.
