School is about to get longer for 20,000 students across the country. The hope is that it'll boost achievement and make us more globally competitive.

Sam Chaltain is a senior fellow at the Institute for a Democratic Education in America. He is also the author of American Schools. We ask him how longer days might help make a student more productive.
