This is a partial list of what’s out there based on a non-exhaustive survey of the Internet. No promises are made about the accuracy of the material; some of the videos were spot-checked for comprehensibility, but no fact-checking has been done. It is up to users to review the films and videos and decide on their suitability. A few that I have used myself are framed by questions I asked students to answer. 
We would appreciate feedback on these videos.
