Since 1988, this landmark publication has given thousands of teachers timeless advice on not only how to prevent and solve discipline problems but also how to teach discipline as an affirming approach that promotes respect for self and others. Now this expanded 20th Anniversary Edition extends the authors' wisdom to new principles for coping with the reality of your world, including: (1) How to address in-school and out-of-school causes of discipline problems; (2) Why to emphasize to students the reasons for your rules; (3) How three internal forces--connection, competence, and control--motivate students to act inappropriately; (4) The importance of conveying that you respect students' ideas and opinions; and (5) The power you have to reframe problems as positive opportunities. Along with the authors' tried-and-true methods--the Three Dimensional Framework for Discipline, the Social Contract, and dozens of proven prevention and intervention tools--discover how to confront newer challenges you face, such as dealing with special needs students in mainstream classrooms, working with difficult parents, and helping students in high-poverty urban areas.
