If you haven't heard of Khan Academy, it's an excellent teaching tool. Salman Khan started by making You Tube videos for his cousins to remotely teach them. He has tutoring videos on many subjects including calculus which you can view at no charge. He went from being a hedge fund analyst to working full time on his teaching videos at the Khan Academy with the help of Bill Gates and the Gates Foundation.
Salman Khan wants to Build a Better University and encourage the use of different teaching tools.
