When I first sat down to read Dr. Robert Mason’s The Puncturing of Space: a Developing Pedagogical Tool, I could not have imagined the impact it would have on me as an educator. As an English teacher I wondered how his work on teaching mathematics might apply to my own pedagogy. It was a game changer.

While working with Doc at The Dalton School in Manhattan, I always valued our conversations about curriculum and how students learn best—when I read his book, it all came together. He articulated what I had always been striving to achieve with my students; he was able to create a visual with his metaphor of puncturing space that any teacher of any subject can call to mind when trying to get optimal engagement and learning from his/her students. Dr. Mason’s work is deeply grounded in a theoretical framework that he makes accessible to even a beginning teacher by connecting theory to practical application.

As reflective practitioners we know that true learning happens when we are pushed just the right amount out of our comfort zones—we cannot learn if pushed too far into fear or remaining entirely at our ease. Dr. Mason explores how to achieve this balance and find that zone—it is not too easy, it is not too hard, it is not comfortable; it is where growth and student ownership begins. “Doc” (as his colleagues and students at Dalton call him—a testament to his humility and approachability) has written an important book on education—his approach creates continued active learning on the part of teacher and student and is a must read for anyone interested in advancing student learning and agency.

Dr Robert E. Mason's Teaching Mathematics might seem far removed from productive pedagogical reading that would be assigned to an incoming Ph.D. teaching assistant in a History department. Indeed, this book should be mandatory for teachers in all disciplines at both the beginning and more advanced levels. ...
