Successful turnarounds of struggling high schools hinge on fostering environments where teachers and students are supported, and parents and community members are engaged, suggests Charles Payne, a University of Chicago professor and affiliate of the university's Urban Education Institute. "You can create all the pockets of good instruction you want, [but] if the organizational environment doesn't support [the change], it is likely to destroy it," he said. Culture change requires a combination of teacher collaboration, community connections, rigorous instruction, supportive leadership and safe environment, he said.
