I was able to get a preview of Google Classroom and in the beta form it looks MUCH easier to work with than the old method of assigning folders.
When you can assign, comment, grade, and review all from one portal. It shows who has turned in and all the normal google stuff is there. It is basically on top of the Google Drive structure.
I wish it had more of a messaging capability and some of Edmodo's quiz and poll stuff. I also wish we could get some iTunesU content involved. Until then I think I need a melding of all three.
