Pico Projectors and the Psychological Edge
If you have not yet checked out Evan Powell's excellent post on pico projectors read it here. While he primarily talks about an intimate sales scenario, the psychological component he discussed was highly applicable to the classroom environment.
I have been watching pico projectors from their inception and was especially excited for the possibilities they have always held for collaborative learning. These devices help facilitate learning and communication among students raised on social media and the notion that to share is to exist. In a classroom environment,the value of a pico goes far beyond its lower cost. In Evan's words, among other things, a pico projector "eliminates the huge pie-chart on the wall with all its authoritarian affectations." Love it.
