I wanted to try my hand at making one. I discovered VideoScribe which is a web based program you can download- free for 7 days and then purchase. It is very intuitive and easy to use.
I can really see this an effective tool to tap into for both students and teachers to create meaningful projects and presentations.
Check out my new VideoScribe that I hope to make into a series: SOS Skills of Studying 2 Minute Tutorials on the SQ3R Method which is an organized approach reading text and articles and studying to get the most out of the material.
