Interesting video, what kind of classes do you teach? Would that be called a visual aid?
I teach tactics classes. When the guys come through the course they sit throug a LOT of classes (about 10 a day) for 3 weeks. They are BEAT. Half the challenge is keeping them interested. So, we (the instructors) usually throw "attention gainers" at the front of the video...as with this one, they often have NOTHING to do with anything.
One of the classes I am going to start teaching in the fall is "Teaching Techniques". I will use this one somehow as a funny example of whta not to do in front of your class.
With any of these videos, if they ain't working, right click on the link, select Save As and try to run it from your computer. TOO Many possibilities as to why they aren't working, too many software combinations, etc.
Sometimes they work when you save them to your machine though.
