YouTube is working now on a new feature which would be great for us in education. The current project is called " Video Questions Editor Beta " which is a way for " multiple questions to be displayed on top of your video during playback that a viewer can answer."
Can you imagine how interactive it would be able to add little quizzes to your videos for your students to work on. I am sure this will make a huge inroad in education. Just keep in mind that for you to benefit from this new feature, you need to have your own channel there which is free of course and most of you have since you have a Google account. You can access this feature through the video edit page on the the edit bar. Type in the questions you want to ask and choose the point in video when it should appear, and the answers that a viewer can choose from.
Anyway, you should also keep in mind what YouTube said at about " Video Questions Editor Beta " :
" The feature represents work in progress, there is no plan for long-term support of the feature and may be removed at any time without prior notification. Your comments will help us improve and perfect the mixtures we're working on."
