Videonot.es – taking notes that are automatically synchronized
VideoNot.es is a great online application to explore if you wish students to make notes upon the contents of a video. The notes that are made are automatically synchronized with the video. So if a note is added about something mentioned 3 minutes into the video then they are time stamped at 3 minutes. Clicking on these notes (at a later point in time) with return to that part of the video.
