This was really fun! I had no idea all this stuff existed. I created accounts on VoiceThread and Voxopop although the last one is for ages 13 and older.
I like the way the voice thread has so many choices of ways to respond and add to the discussion. Seems like that offers all students ways that they feel comfortable contributing.
As I stated before, we use Google docs quite abit already, but you can always find new ways!
