Pages 1-69 are the starting point for anyone interested in DDDM.

Pages xi-xiv, 1-83, 135-164, and 225-254 will ground educators well in basic concepts of DDDM.

Discusses the large gaps between effective instructional practice and what is present in most classrooms.

Contains numerous examples of how schools find time and make structural changes in order to implement professional learning communities (PLCs).

The Introduction and Chapter 6 are the most valuable. The Introduction describes Reeves' Leadership for Learning framework. Chapter 6 describes the DDDM lessons that can be learned from the Norfolk (VA) school district, winner of the Broad Prize for Urban Education. Chapter 7, which discusses effective grading in schools, is also pretty interesting and would be good discussion fodder for classroom teachers.
