Description: Research shows a relative increase in pupils' misbehavior. Teachers often assume that pupils and their families are responsible for misbehavior and rarely acknowledge the fact that misbehavior can also be caused by circumstances connected with the school and teachers. The purpose of this study was to investigate future teachers' views about the role of the school and teachers in causing pupils' misbehavior and the willingness of teachers to prevent misbehavior. Specifically, the study attempted to answer these questions: - According to future teachers' opinion, who is to be blamed the most for pupils' misbehavior? - According to future teachers' opinion, in what way do the school and teachers most encourage pupils' misbehavior? - How confident are student teachers about their preparedness in terms of knowledge of and practical experience with misbehavior, and what additional knowledge would they like to acquire in this field? The research encourages future teachers to consider carefully their possible influence on pupils' misbehavior. If they become aware of such an influence, they can start decreasing it. The contribution of the study is also that it reveals which subjects deserve greater stress in the education of future teachers. Methodology: The research was based on descriptive and causal methods, rather than on an experimental method of empirical pedagogical research. Data were gathered via an anonymous individual questionnaire. The research project included third-year students at the Faculty of Education in Maribor (Slovenia). Conclusions: Research showed that future teachers are aware that misbehavior at school can be caused by different variables. In their opinion parents and society are the most responsible for pupils' misbehavior. Teachers and school mostly cause misbehavior with inconsistency, boring lessons and indulgent discipline. Future teachers would like to acquire more knowledge of and experience in facing pupils' misbehavior, especially in the field of working with difficult pupils, communication and working with parents.
