This video is a bit outdated, but I was assigned to watch it for another course, and I think it has some awesome reminders of the number of ways in which we can incorporate multimedia in the classroom. However, I would not do the Facebook group/page, as that would involve becoming "friends" with students online, and I also think that some of these methods are not integrative, which is not ideal.
This article was a reading assignment for the Science Teaching Methods course I'm also currently taking, and I thought that it had wonderful connections to Constructivist learning and the inquiry model, so I thought I would share. It has some good information and insight all the way to the end!
I love Prezi! I have wonderfully enhanced many individual and group projects with this software. It transforms the information into an animated, generative, sometimes interactive format, that creates a little temporary world in which the viewer is immersed into the learning of the material.
