In this 10th anniversary edition of an Association for Supervision and Curriculum Development (ASCD) best seller, the author reflects on his revolutionary ideas in the context of today's emphasis on school accountability and high-stakes testing. The author relates how his innovative approach--where teachers learn to work with students, rather than do things to them--has withstood the test of time and helped educators create positive learning environments that prevent discipline problems from occurring. Using examples of real teachers dealing with common behavior problems, the author explains: (1) why classroom management approaches that rely on rewards and punishments actually prolong behavior problems; (2) how to turn misbehavior into teaching opportunities; and (3) why changing one's curriculum can solve discipline problems. Following an introduction, this book presents the following chapters: (1) The Nature of Children; (2) Blaming the Kids; (3) Bribes and Threats; (4) Punishment Lite: "Consequences"; (5) How Not to Get Control of the Classroom; (6) A Classroom of Their Choosing; (7) The Classroom as Community; and (8) Solving Problems Together. This book concludes with two appendices: (1) Ten Questions; and (2) Assertive Discipline: A Glossary. Also included are a list of references; an afterword; and information about the author.
