The intention of this diploma thesis is to investigate how the selection of teaching activities and their realization in Music education classes influence students' behaviour. In the first (theoretical) part of the paper, a literature review was performed, which encompasses the problem of student behaviour and an overview of pedagogical model for assessing behaviour disorders. Also, educational activities stemming from the psychological and cultural-aesthetic principles that can be achieved through Music education are systematically presented, and are usually classified in two categories: practical and theoretical activities. The second part of the paper was based on empirical research carried out in three elementary schools in Zagreb. The research consisted of two parts: the first part was carried out using the questionnaire filled in by students, while the second part was carried out using the semi-structured interview, in which Music education teachers participated. The results of the research showed that each type of behaviour of students, at a certain point, is conditioned by numerous factors. Music activities certainly affect the behaviour of students, but do not cause major deviations from the acceptable pattern of behaviour, unlike external factors causing greater deviations, i.e. negative patterns of behaviour.
