Free Technology For Teachers has a great post on how to create Choose Your Own Adventure Videos on Youtube. Looks like a fun way to engage students.
Create Choose Your Own Adventure Videos: "Earlier this week I was one of the instructors at the Ed Tech Teacher Teaching History With Technology workshop. Through one of the other instructors, Greg Kulowiec, I learned how to make videos that you upload to YouTube interactive. By using the spotlight annotation tool in the YouTube video editor you can insert into your videos a hyperlink to other videos or websites. By inserting multiple links into your videos you can create 'choose your own adventure' series of videos.
