Sal Khan deserves a gold medal in my books, or at least some large wooden plaque.
Sal is teaching the world using a YouTube channel, a tablet computer, and 15 minute videos explaining a slew of topics in chemistry, physics, and math. He is easy to listen to, goes at a reasonable pace, and explains science and math in layman’s terms. New videos are constantly being added to both his site and YouTube channel. I prefer to use the website, as I find the layout very simple and easy to browse topics.
Personally, I use Sal’s site to give me a rundown of topics I may be teaching. It would also be useful to pass along to students for extra reinforcement, or if students are absent for numerous days.
Here is Sal’s way to explain the mole (“just a number”!):
