"There is a new #1 in Visible Learning – teachers’ collective efficacy. This book gets to the heart of working together to build the confidence that teachers and school leaders can change the learning lives of all learners, that they then do change their learning lives, and that they collaborate in this endeavour. Donohoo and Velasco ensure we focus on the right problems to collaborate about, that the process can be scaled, and that thinking is provoked to maximise impact. A most worthwhile book that shows the why, the how, and the impact of collaborative inquiry."

John Hattie, Professor of Education & Director of the Melbourne Education Research Institute, University of Melbourne

"The concept Collaborative Inquiry is increasingly bandied about these days with little precision. In one fell swoop Donohoo and Velasco change all that with this succinct, hard hitting, complete, powerful and above all accessible book on Collaborative Inquiry. It’s all there: research, practice, theory, examples and crystal clear charts and guides to comprehension and deep action. _We learn what high quality Professional Learning is, and what it is not (13 comparisons); the 6 Lynchpins of Collaborative Inquiry, the distinction between Professional Development and Professional Learning, and each chapter starts with a ‘Cardwork Map’ that contains the 4 key ideas in each chapter. The Transformative Power of Collaborative Inquiry is as it promises: you can transform learning in your school and district by examining and employing the ideas in this book!"

Michael Fullan, Professor Emeritus, OISE/University of Toronto

"The power of collaboration is evident throughout this book as Jenni and Moses guide readers through an inquiry process that can strengthen every professional learning community. They provide the “how” to the oft-asked question about teacher collaboration and shine light on the path that will get us all there. Their goal is clear – learning – and they hold teachers in the highest esteem as they help us all improve our interactions with our peers to benefit students."

Douglas Fisher, Professor, San Diego State University

"Perhaps the greatest lesson we can learn from The Transformative Power of Collaborative Inquiry is that growth and development involves being open to challenges on the way to learning, leading and authentic collaboration. This book is a must read and a wonderful guide!"

Ann Lieberman, Senior Scholar, Stanford University

"By focusing on the importance of teachers as drivers for school improvement, Donohoo and Velasco highlight an important element that is often overlooked in this crucial learning process. Realizing that school improvement is not an event, they help us engage in the collaborative inquiry process in a way that changes culture in schools, leading to improved outcomes for students. Teachers in classrooms, principals in schools and leaders in central offices all play a significant role in creating the conditions for learning and improvement that are outlined in this very timely work."

John Malloy, Director of Education, Toronto District School Board

"The Transformative Power of Collaborative Inquiry is a quest for educators to learn collaboratively in order to improve student achievement while improving individual and shared educational practices. It blends what collaborative inquiry is with researchers’ work that supports the importance of inquiry as a productive mindset with practical tools, processes, and structures. Donohoo and Velasco build a case that collaborative inquiry can serve as a productive school improvement structure."

Larry Thomas, Executive Director, Oakland Schools Michigan

"Donohoo and Velasco's book provides an engaging, informed and practical call to action for placing educators as the leaders of their own, their peers' and their students' learning through The Transformative Power of Collaborative Inquiry. Vitally they go beyond merely calling for action to providing examples from schools and educators, their own professional experiences, and from latest research evidence. There are many authors who advocate for collaborative inquiry; where Donohoo and Velasco stand out is in a providing a timely must read book with useful resources to support facilitators develop conditions and practices for depth of quality collaborative inquiry to benefit educators and students."

Carol Campbell, Associate Professor, Ontario Institute for Studies in Education, University of Toronto

"Robust and ongoing collaborative inquiry at every level — among teachers but also among school and system leaders —has been shown to improve schools and school systems. Yet such collaborative inquiry remains relatively uncommon. This book enables collaborative inquiry “at scale” by combining an informed and nuanced grasp of relevant research with astute and practical guidance derived from the authors’ own extensive experience."

Judith Warren Little, Professor, University of California, Berkeley

"The Transformative Power of Collaborative Inquiry is a fantastic resource for anyone interested in realizing the enormous potential of collaborative inquiry to substantially deepen the learning of students, adults, and educational systems. With a rich collection of guidelines, tools, and examples, Jenni Donohoo and Moses Velasco bring clarity and precision to the what, the how, and the why of effective collaborative inquiry. A valuable and timely book for change agents in schools and districts."
