The purpose of this study is to portray conflict managing associated with children in a small class and what problems they may face each day at school. What types of conflicts and what consequences do teachers practice? This study is based on these following questions: Is there any difference for solving/measure for students with psychosocial problems or ADHD in a conflict or does teachers still works with the same methods? What types of conflict solving does schools use? What is important to consider with students in a small class who has psychosocial problems and ADHD to prevent conflicts? Summary: To answer my questions in this study, I´ve used qualitative methods, interviews and observations. I have used my cellphone for recording the interviews so that all content from the informers are accurate. My theoretical points concerns on having strict rules both inside and outside the classroom. Teachers in school use first one method in conflict solving, a need based approach, which means that teachers first listens to the involved students and interacts thereafter. Every school in Sweden has a document called Plan for equal treatment, which guides teachers on how to deal with conflicts. They also use other rapports such as arrangement plan and incident rapport. The conclusion of my study is that children with psychosocial problems do feel better harmony with strict rules. They need guidance and goals so they know what to do and what is expected of them. If the rules bend, it is more likely that conflicts and other disorder in the classroom emerges.
