ALSB member Jason Mance Gordon from Georgia Gwinnett College maintains a YouTube site with a hundred or more short informative videos on BLAW topics. I find that sometimes it is important to stop prattling on in front of the class and show a video, even if it is just another professor talking. It is at least something different that causes students to look up from their computers. Also, links can be provided for students who need a quick explanation of a concept. As always with YouTube videos, you should screen the video first to make sure it is consistent with your own teaching.
