If you use YouTubes in the classroom and want to put one on continuous repeat mode just change the URL. I am teaching a film soundtrack unit and asking students to create their own soundtrack for a film. To practice as a group I was replaying the YouTube without sound and getting students to try out different concepts. One of my students suggested I use an easy trick to put the YouTube on loop.
Here is a screen shot of the URL on the original YouTube page.
All you have to do is replace the word “tube” of “youtube” in the URL with the word “repeat” so it looks like this and you will be taken to another page where when played the YouTube repeats itself in a loop. Pretty easy and useful!
