The market leading Canadian edition of Principles of Classroom Management balances theory and research with practical tools to help teachers make sound decisions in their classrooms. It remains, like the previous edition, focused, relevant, and well-written, with pertinent Canadian details and language. The new edition continues to show new Canadian and international research, and contains reference to the Canadian Charter of Student Rights and Freedoms, relevant sections of the Canadian Youth Justice Act, new part-opening iterative cases, new kaleidoscope cases which present a classroom situation from a variety of perspectives, a new decision-making model (CALM), and a Companion Website with multiple-choice self-study questions and complex cases.
