With EDpuzzle, teachers can make any video into their lesson. EDpuzzle combines simple video-editing tools with powerful analytics so that a teacher can take a video and make it personal, engaging and effective. Take already existing videos from Youtube, Khan Academy, Crash Course, etc., or upload your own; enable self-paced learning with interactive lessons, add your voice and questions along the video; and know if your students are watching your videos, how many times and see the answers they give. EDpuzzle is currently building a pool of the best video lessons for the classroom.
