Tool#6 Web Tools for Discussion
I use Edmodo frequently with my students. They submit some of their assignments/projects to me through Edmodo.
A couple of years back I was asked to try out Voice Thread with my students for a short period of time and I posted pictures and comments for my class to discuss. It was a very good way for them to practice written and oral communication in English. They were shy at first with the video option. I was disappointed when funding wasn't there to continue, but it looks now that like the district has subscribed. Thanks!
