A classroom revolution is overdue, not only for improving learning but for the health of our democracy. In this inspirational talk Katherine Cadwell shares how after 30 years in education she completely flipped her classroom and teaching style. The Harkness method puts the focus of learning back onto the students: teaching them how to ask critical questions and the skills of civil discourse. Katherine has been a teacher at Harwood Union High School since 1981 she is a 2016 recipient of a Rowland Fellowship, the 2016 Foundation for Excellence in Education Award and the 2016 Gilder Lehrman Vermont Teacher of the Year. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
