"It's amazing what you can do with boxes and junk," he says.
That could almost be the slogan of the New York Coalition for Play, which provided the boxes and junk. The nonprofit association ran one of the two dozen booths at the Ultimate Block Party, an event last fall that brought together companies like Disney, Crayola, and Lego, along with researchers from Columbia and MIT, and attracted thousands of parents and children. The goal was to "celebrate the science of play" and to push back against the notion that education happens only when students are seated at their desks, staring at chalkboards, and scribbling furiously in their notebooks.
