During the summer, we interviewed Tony Bryk, Author of Learning to Improve: How America's Schools Can Get Better at Getting Better and head of the Carnegie Foundation for the Advancement of Teaching. His work was seminal in the creation of the Framework for Great Schools, which has spurred New York City schools to rethink the structures and processes that lead to student achievement. And, the NYC Department of Education is currently conducting a pilot using the tenets of improvement science to drive individual school efforts to improve their practice. Here are Dr. Bryk's responses to our questions about improvement science and NetworkED Improvement Communities (NICs).
