I recently came across this resource when reviewing some of Edmodo's top apps of 2013. This resource is similar to Edmodo's Blendspace app, NextLesson lets teachers transfer a variety of material into one place. Teachers can upload video clips, documents, links, and more. This site does do something Blendspace does not, it tracks student movement on the site. For instance, students cannot move on to task two without completing task one. Like Blendspace teachers can use and edit other teachers projects or create their own project from scratch.
