Sal Kahn has built a tremendous collection of over 1800 open-licensed videos offering instruction in math and science. They cover topics in arithmetic, algebra, geometry, statistics calculus, and more. These videos are licensed under CC BY SA which means you can use them free of charge and even host them on your own web site, as long as you agree to share (use a CC BY SA license) on any derivative products you build.

Up until now, the videos have only been available on YouTube, which has posed problems for educators. Now, however, the Khan videos are available elsewhere! Curriki has them available as both embeddable and downloadable files. They have also created a group to “organize, extended and build a community of practice around this content.” This is a great opportunity to collaboratively remix this content and add to it. (I have some ideas myself to to remix some of this into a series of middle school math courses in Moodle.)

Another site has collected the Khan videos for download onto a USB drive or server.

There are sure to be more creative uses of this great collection of content to come.
