With the idea of "flip" teaching in mind, I have begun screencasting. You can view the screencasting by choosing the links in this page or by going to my YouTube Channel directly. If there are topics or specific examples that you wish to see, please contact me, mister.yim@gmail.com. Squeaky wheel gets the oil, so ask! I'll be adding more screencasts as time permits. In the meanwhile, you can find math lessons made by made by many capable people in the world wide web. You can start your search at Khan Academy.
