In his book, The Back Of The Napkin, author Dan Roam asserts that that everyone is born with a talent for visual thinking, but that we — especially in the business world — are never encouraged to develop it. In this video, Roam shows us how anyone with a pen and a scrap of paper can exercise their imagination and work through any business problem by creating pictures.
Teachers may find his suggestions useful for imagining how to work through ways to use Tablet PCs in classrooms in order to increase student learning rates.
