A research study of eight schools that won the U.S. Department of Education’s National Award for Model Professional Development has been distilled into this brief and compelling story of successful school reform. Teacher voices and vignettes give life to the guiding principles that researchers identified across these disparate sites. Annotated lists of resources provide concrete help in putting these principles into practice. And profiles of each school’s journey demonstrate that extraordinary results can be achieved from even modest beginnings.
