Ten years after its first publication, The Teaching Gap remains "a critical resource" (Publishers Weekly) for anyone involved in education. In paperback for the first time, it has been fully revised and includes a new preface and afterword by the authors. American schools have famously lagged behind foreign schools in all areas of academic achievement. When James W. Stigler and James Hiebert made their assessment of the Third International Mathematics and Science Study (TIMSS) ten years ago, they discovered that the problem with American education is neither one of testing nor curricula, but teaching. A clarion call for treating teaching like the craft it is, The Teaching Gap lays out a clear program for change that administrators, teachers, and parents can implement together. Newly updated with fresh teaching solutions drawn from new research, this educational classic is as vital a teaching tool as ever.
