This text is a companion to Wienstein and Mignano's "Elementary Classroom Management". The book is a core text in classroom management courses for secondary majors and can be assigned with the elementary text for courses enrolling both elementary and secondary majors. Like its companion volume, it combines what research has to say about effective classroom management with practical knowledge culled from real teachers at different grade levels and in different subject areas. This is done by integrating into the research discussions case studies of four practising teachers. The research discussions comprise approximately two-thirds of most chapters and the case studies one-third.
