Edmodo is a free and secure social learning platform for teachers and students to collaborate and connect in the 24/7 classroom. The design and functionality of Edmodo is similar to Facebook, but the focus is on teaching and learning within a protected environment. Students don't even need an email account to sign up.
Teachers and students can extend the learning by posting messages, holding online discussions, picking up work and turning it in. Edmodo supports a variety of multimedia to provide students with flexible learning paths including links, images, video and interactive graphics created with ThingLink.
