Their book is an inspiring guide to current and future school teachers and to college and university professors—indeed to everyone who teaches anything to anyone else.   Arguing that teaching is an art, Banner and Cannon help teachers understand its components. They analyze the specific qualities of successful teachers and the ways in which these qualities promote learning and understanding. Throughout, they illustrate their discussion with sharply etched portraits of fictional teachers who exemplify—or fail to exemplify—a particular quality. Neither a how-to book nor a consideration of the philosophy, methods, or activities of teaching, this book, more precisely, assesses what it takes to teach. It encourages teachers to consider how they might strengthen their own level of professional performance.
