eduCanon is a free service for creating, assigning, and tracking your students' progress on flipped lessons. eduCanon allows you to build flipped lessons using videos from a variety of sources including YouTube, Vimeo, and TeacherTube. You can create questions to appear while your students are watching videos that you have assigned to them in your eduCanon online classroom. In the video embedded below I provide a demonstration of how to create a lesson in eduCanon.
Edmodo users will be happy to see that eduCanon offers an Edmodo app.
