I was speaking with Marc Prensky last month lamenting about how interactive whiteboards were dumbing down instruction and sharing how teachers could be much more effective by ditching the boards and just using a laptop (or doc camera) and projector. Marc said, sometimes you need to show not tell.
That conversation came to mind as I ran across this slideshow from a presentation sponsored by Smartboard about using Smartboards in a 1:1 classroom. The presentation was filled with lots of examples of the dumb ways in which people use interactive whiteboards.
Even though Smartboard used these photos in a presentation to sell the device, they're their own worst enemy sometimes. I invite you to view this photo compilation which can serve as a model for what not to do when using IWBs.
