I have also used podcasts in the Sped class. They are a neat tool that allows you to watch something on your own time. I didn't know itunes had them for free, and that there were so many of them available. This is something I am going to check out more thouroughly.
I knew a little about wikis, but not to the extent of what we learned in class. I knew they were sites that all or some peolple could add to and change, but I had only seen them as an informational source. They way we used them in class was way cool!
