I used Edmodo this past year with a several groups of students, including a group of students who were working on independent, differentiated projects and it was a great way for them to check in and reflect upon their learning each day. They could also see what their classmates were doing and comment. The Facebook like format is more appealing than some of the other educational tools for kids but it is still, at the end of the day, an "educational tool," not a place where kids will go to "hangout" where authentic conversations could happen. That's what I am trying to figure out -- how to reach them where they really are...
