Abstract
This thesis is part of the pilot project “Disorder in Schools”. Professor Liv Duesund leads the project. It is a case study, which aims to identify the characteristics of disruptive behavior of one student during class. The focus in this study is laid on what is ranged as the highest frequent disruptive behavior in schools today. I have found it relevant to elaborate on interactions between the Informant and other participants in his school environment. Based on my observations, it may be said that peer interactions and peer relationships, and therefore poor self-esteem of the student may be influencing the behavior.
