Massachusetts-based science writer Elizabeth Kolbert has a provocative proposal: kill school sports.
She argues dropping sports would help U.S. students focus — and improve their test scores. She cites a new book, "The Smartest Kids in the World." It tells success stories of places like Poland. Test scores in the eastern European country have risen from below the developed world's average to significantly above it. Polish schools, like many in Europe, simply don't have sports.
