An instructor's resource book, developed with funds from the National Science Foundation and the Pew Charitable Trust, that presents an entirely new approach to teaching introductory physics, complete with a step-by-step guide for converting conventional lectures to a more interactive format and a ready-to-use set of classroom materials in print and on disk. FROM THE BACK COVER: Eric Mazur is Gordon McKay Professor of Applied Physics and Professor of Physics at Harvard University. He has taught introductory physics at Harvard since 1984. In addition to leading a research program in optical physics, Mazur maintains an active interest in educational innovation. In 1991, Eric Mazur developed Peer Instruction, a simple yet effective method for teaching science. His approach involves students in the teaching process, making physics significantly more accessible to them. His technique has been highly successful and numerous instructors are already using Mazur's approach in their classes. Many instructors have pointed out the benefits of teaching by questioning over the more traditional approach of teaching by telling. Here, at last, is a book that not only explains how to teach by questioning but also provides all the necessary tools to implement this new approach with a mimimum of effort.
