Duncan wants a "revolutionary change" in teacher training

Education Secretary Arne Duncan is calling for "revolutionary change" in college programs that train teachers for the classroom -- responsible for educating at least 80% of the country's teachers. In a speech prepared for delivery today, Duncan said that traditional teacher-preparation programs do not give educators enough classroom experience and do not guide them in using data properly. Officials are predicting about 1 million teaching vacancies over the next four years as veteran baby boomer teachers retire, and teacher training must become a priority, Duncan said.
