EDpuzzle

EDpuzzle is easily Bellmore-Merrick Central High School District's latest technology obsession. Most of our teachers are using EDpuzzle's to enhance their flipped video content (either content that they created on their own or content taken from the Web). They can add questions right into the video, creating a much more interactive experience for their students. 

From the EDpuzzle website: "The easiest way to engage your students with videos. Pick a video, add your magical touch and track your students' understanding.

• Save time: Take already existing videos from Youtube, Khan Academy, Crash Course, etc. or upload your own.
• Engage students easily: Enable self-paced learning with interactive lessons, add your voice and questions along the video.
• Reinforce accountability: Know if your students are watching your videos, how many times and see the answers they give."

This website is free and there is an iOS app, Android app, Chrome app and a YouTube extension.
