I frequently check YouTube for videos for my classes. I’ve found some gems, but I’ve also waded through some dreck. This video shows how to use YouTube Playlists to find quality videos much more quickly, curate videos for your classes, and to use playlists in lesson plans.
Other video tips, use EdPuzzle to further edit YouTube videos. As FCS teachers, we all have the extension added to YouTube. Just click Edit with edpuzzle.
Finally, if concerned about distracting thumbnails for other videos and content, use a tool like safeyoutube.
