Want to hang out with a bunch of really smart people? Spend a day at a convention of school librarians. That's what I did on Friday, November 15 in Hartford, Connecticut at the biannual convention of the American Association of School Librarians.What makes them so smart? They are exemplars of what the Opening Session speaker, Tony Wagner, author of Creating Innovators: The Making of Young People Who Will Change the World, says the country needs if we are going to produce the many young innovators needed for our technology-driven new world order. According to Wagner, it is play, passion and purpose that drive young innovators.
