Khan Academy

Thousands of FREE, short, online videos that are focused on explaining and modeling the learning of specific topics in math (basic arithmetic and math to calculus), statistics, biology, physics, chemistry, finance, and other topics. The topics cover K-12 levels and higher education. The simple and clear presented information enables learners to see and review the topics and how to solve the problems at their pace with as much practice as they wish.  In particular there are over a thousand videos just for mathematics.  The site also contains a handful of interactive mathematics learning objects that are of the drill and practice type.

Khan Academy is perhaps one of the best-known free educational websites. For the Educational Theorists and its students, this resource is a great example of Cognitivistic layering in practice. Excel in one area? Khan academy will move you to the next. Or, perhaps you need some help along the way, the resource will help you there too. Students love the site, and I would have to say, as a mathematics educator I am a fan. Set up an account as a Teacher and direct your students to some of its materials. In fact, why don't you give the World of Math a turn and see how you fare swimming through the entire math curriculum, from kindergarten to undergrad.

I absolutely love this website. It is suitable for students of all ages since it covers everything from basic math to calculus. I also really like that it had test prep (eg SAT). The mode of instruction is great for visual and audio learners, as he talks through every step he is writing.

Awesome! This site is a great help to everyone because we all struggle with one concept or another... well, everyone except Khan :) Thanks for posting this site. I plan to use it in the near future.

This is GREAT! I think students who are visual learners like myself could really beneift from this website. I liked that it provides help for multiple subjects, including science.
