The central theme of Principles of Classroom Management is the importance of the teacher-student relationship in fostering positive student behaviour and academic success. The authors focus on the critical nature of language and labelling, placing the onus on teachers to modify either their behaviour or the situation.   The other pillar of Principles of Classroom Management is its up-to-date Canadian content. It reflects Canadian values through its references to current Canadian research, discussion of changes in Canadian schools, and coverage of best practices across the country. The case studies have also been revisited to ensure they reflect real, current issues in Canadian schools.
