I have put all of my PowerPoints for World History on YouTube. It was hard to find the images and some of them are pretty basic summaries of the chapters. However, some of the kids are using them now. With most of the chapters from the book now done, I have about 30 World History videos up and running.
I have doen some with my Non-Western Culture class but not enough. I did more with a site called WallWisher to have the students post what they know and what they want to know about the different topics. Shockingly many of them want to eat food from different countries.
In both of these classes I am just starting to use Google Forms to give the students practice tests to prepare them for the real thing. So far the students seem to like it and appreciate the extra practice.
I am greatly looking forward to starting up the kid directed wiki this semester. We just upgraded our bandwidth and now it should be much easier to have the students all working on the different parts of the wiki with video, links, and images than it was before.
