Since 1994, Ron Ritchhart has been involved with Project Zero at the Harvard Graduate School of Education, aiming to understand how to develop, nurture and sustain thoughtful learning environments for both students and teachers. His books Making Thinking Visible and Creating Cultures of Thinking have not only put out a call for action for schools to become inspirational environments that bring out the best in all learners, but they have also offered concrete strategies and approaches to make that happen.
