I took the videos that many of my colleagues use on a regular basis and made a Symbaloo (a really cool visual bookmarking tool that helps people keep their favorite links in order.) First, I converted each video into a link on SafeShare.tv - a wonderful site that generates a safe link for YouTube videos. It removes all the yucky stuff you don't want. You might have one ad pop up at the bottom of the video right when you hit play, but that's about it. No more questionable content on the sides and nothing comes up when the video ends. Woo hoo!
So, here it is!
When I find engaging videos, I add them to my Symbaloo which updates automatically. If you have a favorite that you'd like to suggest I include, just leave me a comment and I'll check it out. (My Symbaloo was updated in September '14 to include new videos, GoNoodle and many Kid President videos.)
