I like this idea a lot....the videos and other visual representations I think help tremendously. Some students don't realize that visuals like videos, pictures, etc. actually are a good learning technique and help students remember and grasp the concept better. Students are learning when they think they are not.

This is a really new a exciting thing for teachers to do. Not only is it more fun for the students who get to "teach" it but it is also exciting for the groups that gets to listen. We all know that the best way to learn something is to teach it! I think it might also open the eyes of the students who might see that it isn't always easy for teachers to come up with exciting activities that will keep everyone’s attention.
