Evidence and Decision Making illuminates the crucial roles that teachers, administrators, and other education professionals play in constructing and using evidence to make decisions that support learning. Authors analyze different practices of constructing and using evidence in classrooms, teacher communities, schools, and school districts; consider the roles that district, state, and federal education agencies can play in supporting sound practice; and provide historical contexts, theoretical resources for studying evidence use, and epistemological resources for warranting different types of decisions. The volume provides a realistic and complex vision of what counts as evidence and how evidence is or might be used to inform professional learning and decision making across levels of the educational system.
