Virtual Nerd is developing some very interesting video tutorials. The videos are primarily symbolic and procedural but they are thorough , organized, and model notes accompany the videos.
they are in the process of developing physics videos.
I'm no slouch at maths, but this site has taught me lots. See videos of maths theories at the forefront of research presented in an understandable way.

"resources for understanding how Common Core will shift high school math classrooms, with example videos, articles about assessment and lists of tech tools for educators."
A great maths video tutorial site that covers all the basics. Great to use for extra support or home study guides.

"While it's true that most people in math class don't learn much math, most kids in French class don't learn much French. But, we don't say that they are not "French-ly minded." We don't say that they don't have a head for French because we know that if they grew-up in France, they would learn French perfectly well. And I think that my image of learning mathematics is that if we all learned mathematics in "Mathland," we would all learn mathematics perfectly well. "
This is a series of videos about doodling in math class. They relate, although sometimes loosely, to topics from geometry, algebra, trigonometry, and precalculus. Very fun to show students as a side-note to regular lessons.
