The Fourth Edition of Principles of Classroom Management provides a theoretically-based but practical system for helping teachers prevent disruptive behavior and influence appropriate behavior while continuing to provide a positive learning environment for their students. This concise text presents an array of decision-making options that guides teachers in thinking about how to approach particular classroom management situations and choose from a range of options designed to prevent, cope with, and solve a variety of problems. A variety of theoretical perspectives, each fleshed out with cases taken from actual classrooms, gives students many choices in how to handle issues that may arise in their own classrooms.
