I recently saw an interesting YouTube channel called PBS Presidents, that highlights each president in a very short video from 60-90 seconds. Not only are they fun to watch, but very informative. Check out the Gerald Ford sample (of course I had to honor the only President from Michigan).
What really got me thinking was how something like this could be reproduced by students in the classroom. There are loads of tech products that allow students to create audio slide shows that can be customized to any topic that's being covered in class. A few of my favorites are listed here.
