YouTube has some great content, the tools described in this video will make it much easier to use YouTube in the classroom.
QuietTube – To watch web videos without the comments and stuff, just drag the button below to your browser’s bookmarks bar. On any of the supported video pages, click the bookmark button to watch in peace.
Tube Chop – TubeChop allows you to easily chop a funny or interesting section from any YouTube video and share it.
The final tool in the video, Keep Vid isn’t to be recommended as I explain in this blog post.
