Here’s a great rubric for getting you started on implementing online discussions in an accountable way.

As far as what works best in the classroom, I use Schoology.com. You can create rubrics, grade from your smart phone, post content in a meaningful and wonderful way, and keep kids in the loop and prepared for college. It is definitely a step up from Edmodo, but a very worthy and intelligent one if you are needing to add more to your classroom’s online presence.
Let me know if you have any questions!
