Think of this as a "how-to" for educators, professional developers, teachers, principals, etc. who seek to establish Professional Learning Communities in their organization. The book is a compilation of some of the best practices related to PLC's.
In professions such as engineering, medicine, law, etc., collaboration between colleagues about the results being obtained from specific practices, and what effects changes/refinements to those practices can have on results, is nothing new or controversial. In education, it seems the hardest thing to do is to hold professional and collegial discussions about classroom practice and its effect on student achievement. This book provides a practical "how to." Good reading.
