“We are prisoners of the pictures and experiences of education that we had,” says Tony Wagner, expert-in-residence at Harvard’s educational innovation center and author of The Global Achievement Gap. “We want schools for our kids that mirror our own experience, or what we thought we wanted. That severely limits our ability to think creatively of a different kind of education. But there’s no way that tweaking that assembly line will meet the 21st-century world. We need a major overhaul.”
