To me this video supports my thoughts about loose parts that encourage children to think creatively. We need to nurture in children the ability to think outside of the box, to think divergently. Saracho & Spodek explain divergent thinking as, "the ability to branch out from a starting point and consider a variety of possible solutions, involves fluidity of thinking, board scanning ability, and free association. It is thought to be a major cognitive process underlying creativity."
Going back to David Perkins - "it is never just problem solving it involves problem finding."
