Check out this website I found at classtools.netI love using videos in class. One of my goals for this semester is start making some more videos myself. I am thinking of using puppets to deal with the issue of privacy and avoid exposing children.
I was really amazed when I found out about interactive you tube videos http://preview.tinyurl.com/mbpo3p. The article I am quoting from classtoos.net not only features some videos but also has a guide teaching you how to make them.
I hope you enjoy it.
