This book is about different ways of seeing; different ways of seeing supervision, different ways for supervisors and those they work with to see themselves, and different ways for supervisors and other classroom observers to see classrooms. In an effort to expand thinking about supervision, this book takes a broad view of the field, its practitioners and their practices. There are many types of supervisors to be sure: university supervisors, central office supervisors of all types, local schoolbased supervisors-principals, assistant principals, media specialists and teacherleaders-and many more who perform some supervisory tasks. This book is applicable to all of those and to others who are involved in instruction and instructional leadership, whether primarily school-based, university-based, centraloffice based, or based in a state department of education or a regional education service agency. In short, I do not want what is written here to be dismissed out-ofhand by a reader who might think the findings and implications of this book are only applicable to someone else. I invite anyone who works in/on instruction to read it and to make the proper applications, as they fit one’s local situation.
