Ed Puzzle is a free to use web tool that enables you to transform videos into an active learning environment. You can use your own videos, or videos that you have found from another source, like YouTube or Khan Academy.
Ed Puzzle gives you the tools to crop the videos down to just the clips you want the students to watch, to add your own audio commentary and notes and also to slip in some questions for the students to answer – a great way to encourage some deeper thinking and to check how they are engaging with the subject.
To use EdPuzzle you will need to sign up for a free teacher account: Ed Puzzle Sign up
