Projects are described that emphasize broad-based or comprehensive approaches to educational change, and are the result of a communitywide planning process designed to identify and then address core educational problems. Projects included in this publication are divided into "Changing Schools," which contains descriptions of projects whose primary intent is to alter the organization, norms, curriculum content, or structure of a single institution (generally a school building); "Changing School Systems," which includes projects that address in some way systemwide or multiple-school problems; and "Change Through Dissemination and Training." These projects present several creative approaches for disseminating information on promising educational practices and for helping teachers adopt new materials and instructional techniques.
