Classroom management is one of the main difficulties encountered by teachers. One way of improving this situation is to implement classroom management strategies that have been validated by scientific research. The purpose of this research is to study the classroom management strategies declared by a sample of novice teachers, and the sources of information on which they say they base their choice. To this end, semi-structured interviews were conducted with 42 French-speaking Belgian novice teachers. These interviews were subject to thematic content analysis. The teachers report implementing certain classroom management strategies considered effective in the scientific literature, as well as practices that are less effective according to the scientific literature. To choose their strategies, they say they mainly rely on the advice of colleagues, examples suggested on social networks, and/or their initial training. The results of this study can be used to formulate ways of improving teacher training both in French-speaking Belgium and more widely.
