Ed Puzzle for Youtube videos
EdPuzzle – There are several tools available to add questions to a YouTube video, but EdPuzzle remains one of my favorites. It has one of the best video libraries to search for the content that you want to use with students. You can trim the video to the length you need, add quiz questions for students that are timestamped to specific points in the video, add your own audio narration or voice notes, and even upload your own screencasts. Teachers can also prevent students from skipping ahead in the video to get to the questions, if required. Data from student responses are stored in the teacher dashboard.
