This not only disrupts teachers and classmates but also the ongoing learning process. Using typical case studies, this compact handbook provides you with concrete action patterns, training opportunities, and measures for direct and quick responses to disruptions. You will learn to present yourself more effectively, draw meaningful consequences from students' behavior, and handle disruptions confidently and assertively.
