A secure social network just for your classroom
Jeff Dunn posted recently on Edudemic about Edmodo:
"There is a social network designed just for your classroom and it's called Edmodo. You may have heard of it during a conference or perhaps in the hallways. However, like any new technology it can be challenging to find the time to explore and adequately integrate it into your classroom."
His post features a one page "cheat sheet" for getting started on Edmodo.
