This document discusses factors that are important for sustaining educational innovations over time. It outlines five essential components of the cooperative learning model developed in Durham, England, including teachers attending training voluntarily and in teams, administrators attending, teachers applying what they learned within two weeks, training being an ongoing process, and communication between educators. Key factors for maintaining innovations include strong leadership at all levels, continuous training to review basics and learn new strategies, communication among educators in learning communities, and keeping the original moral purpose of improving student outcomes at the center.
