EDpuzzle allows user to make any video a lesson by embedding teacher-created questions and comments, while also monitoring to make sure that students are actually watching the videos. As the administrator, you can see how many times a section of a video was watched and how many times a student attempted to answer a question. And students have to watch the video; if a new tab is opened, the video automatically stops and waits for the student to return to the EDpuzzle tab to resume viewing.
Below is the training deck that I created and used as part of a presentation at my local Regional Office of Education's Tri-County Institute, a day of professional development for educators throughout the three counties, which includes a lot of content developed for teachers by teachers. My presentation was interactive, so participants were able to watch pre-made EDpuzzles and make their own resources.
