As a classroom teacher, I have often felt alone, isolated, and overwhelmed. After 12 years in education, I was searching to re-charge my batteries and re-connect to my initial core-beliefs and understandings about my content and my craft. Dr. Kolis' book reaffirmed my basic concepts of teaching and learning by providing a vivid, specific portrait of mastery-teaching and collaborative leadership using clear, precise and concise language and terms. Not only does this book define high-quality teaching and collaborative leadership and set it as goals we should all strive for, it provides the reader with a framework and process to achieve those goals. This book invites educators to become part of the process of revitalizing schooling on the personal, classroom, curricular, building, district, state, and national levels.
