This is the story of how four of the largest and most successful reform organizations in the United States--Education Development Center (EDC), School Development Program (SDP), Harvard Project Zero (PZ), and Coalition of Essential Schools (CES)--came together to form a unique partnership known as ATLAS (Authentic Teaching, Learning, and Assessment). This ground-breaking volume provides a detailed glimpse of the individual workings of these influential organizations and, more importantly, how they combined efforts to uncover the craft of school reform--what teachers, administrators, and staff developers actually do to provoke and support change. Through personal interviews with Janet Whitla, James Comer, Howard Gardner, Theodore Sizer, and others, you will hear the voices of renowned reformers telling another side of the school reform story to complement the policy side. It's about networks of people working behind the scenes--working closely with teachers and schools over many years. This honest account, by reformers on the "inside," is essential reading for anyone who wants to understand American school reform at the end of the twentieth century.
