Last week YouTube announced that the popular annotations option in the YouTube editor is going to be removed at the end of April. While annotations will be missed by many, it was a great tool for creating a "choose your own adventure" series, there is still a similar option available. End screens in the YouTube editor will let you link the end of one of your videos to the beginning of another video or playlist. In the video embedded below I demonstrate how to create interactive end screens in your YouTube videos.
Applications for Education
If you're making a bunch of tutorial videos for your students, using end screens can help you direct them to watch your series of videos in the proper sequence.
