In preparing the database of free online classes, I’ve sorted through thousands of courses on the net. While text-based courses are the most common, there are some very well-made video classes out there.
You can find an online video course for just about every introductory-level topic. Consider these: basic cooking, Algebra, world history, Spanish, music, weight training, guitar, and salsa dancing. A special shout-out to Annenburg Media, in particular. They offer full-length streaming video courses on their website at no charge. Each course has multiple sessions and many hours of high-quality instruction.
There are so many video courses that I can only list a few here. But, you can browse through them all in the massive list of free online video courses.
