Edmodo is a FREE, safe and secure social networking site designed specifically for education. Teachers can share ideas, files and assignments. Once you have an account, you can create groups for both classroom and professional needs. Edmodo provides tools for grading and polling. Teachers can also share resources in their library.
Teachers have control over the groups they create, managing the group members (teachers and students). Groups can also have co-teachers for a particular class. Messages and web links can be sent to one or more groups or members.
You’ll be surprised how easy Edmodo is to use. Read more about it Edmodo’s press link or just sign up for an account and try it.
