The professor at the Institute for Educational Psychology at the Technical University of Braunschweig divides her book into a theoretical and a practical part. In the theoretical part, she defines the concept of disciplinary conflicts against the backdrop of today's school conditions. She discusses their manifestations and prevalence. To explain the emergence of disciplinary conflicts, she draws on numerous relevant research findings, which she presents in a very clear format and interprets regarding their significance. In doing so, she critically examines - always based on established knowledge - commonly expressed assumptions about the causes of disciplinary conflicts: student issues such as violence, ADHD, or learning difficulties; the general increase in behavioral disorders among students; and the growing heterogeneity.
