I saw this linked passed through Twitter from Dennis Callahan, it’s 10 Free Online Educational Video Options. The list was compiled by Ace Online Schools blog.
“Ace Online Schools is a guide to useful online resources for students and professionals. In addition to our own tips and tutorials, we recommend websites and applications that help you work and live more productively.”
I was aware of the first few as they are quite mainstream but am grateful to see the remaining fantastic options. I’m not a school teacher, but there definitely appears to be some great resources here for instructors in general.
