In a 1968 study of daily life in classrooms, Philip W. Jackson wrote that students spend as much as 50 percent of their time waiting for something to happen. They wait for teachers to pass out papers. They wait for slower students to get their questions answered. They wait for the lunch bell to ring. Alas, forty-five years after Jackson published his book, millions of American students are still waiting. They’re waiting for all of the old reasons, and one relatively new one: they’re waiting for our education system to catch up with their lives.
