Interesting views about the future of our libraries. The use of videos such as these can be powerful in the classroom. The informative, sharing aspect between peers is extremely helpful. There is also the ability to share with students things they would otherwise not experience in their learning environment. Whether it be a discussion or presentation, a visual, or a lab demo as modeled here....students' learning can be enhanced by watching first hand what is being talked about.
It goes without saying that the younger generation is a HUGE fan of the YouTube site. Bring that into your classroom and it can't help but create curiousity and interest in a student.
