Online classes and new sites for classes

Today for my online classes, I gave the students between my two classes and the four high schools that they are in a different kind of assignment. Each group has a different website to learn and create a presentation on how to use it. When they are done, I will put the presentations in one place so the students in any of the classes and schools will have access to them. The sites I chose to use are bighugelabs, blabberize, glogster, voicethread, toondoo, and dipity. Not sure how this will work but I did find out today that I need to write instructions more exactly and clearly. Hopefully this doesn't totally flop, am interested to see how it turns out.
