Easton, a former middle school teacher, consultant, coach, and author who was a professional development director at a high school, argues that professional learning communities should be self-organized and focused on learning. She describes how professional learning communities are developed, structured, matured, and sustained. The text follows a fictional middle school in the process of creating such a community over the course of a year, commenting on the process and providing ideas and tools for teachers to use in their own environments. The accompanying CD-ROM contains surveys, articles, templates, activities, worksheets, and many other resources. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
