A superhighway is being built across today's education landscape, extending from preschool to graduate school, writes Armstrong. This superhighway bypasses all the byways, narrow routes, and winding paths that have traditionally filled the road from early childhood to early adulthood. As schools race to move students through the curriculum at breakneck speed, they ignore the needs that they should address at several developmental stages--early childhood, middle childhood, early adolescence, and late adolescence. Armstrong describes the kind of instruction that is developmentally appropriate at each of these stages. He asserts that educators must dismantle the curriculum superhighway to preserve students' right to grow and develop.
