The authors, whose work at Harvard Project Zero, the Coalition of Essential Schools, and the Annenberg Institute for School Reform has placed them at the forefront of new assessment strategies, have created a practical, user-friendly guide to provide teachers with strategies and resources for working together to examine and discuss student work such as science projects, essays, art work, math problems, and more. Written for teachers, administrators, curriculum coordinators, staff developers, and researchers, this book offers a clear process for starting and sustaining collaborative discussions of student work and student learning.
