YouTube is fun, and the choices are endless. I watched at least 30 different videos about librarians, some funny, some not so funny, some that were inappropriate, some that were boring, and some that were actually okay for a school assignment. The one I chose shows a young librarian defending the Dewey decimal system.
On Teacher Tube I found a video on Metaphors: Star Wars Metaphors. I am teaching metaphors to my ESL students right now, so I will use the video myself.
There is just about anything a teacher or librarian could possibly be looking for. To make it even more perfect, links to worksheets, lesson plans, assessments, and more are provided at the upper edge of the video.
