The purpose of this graduate research was to encourage positive interpersonal relationships in the class community through the development of moral values by introducing a more significant educational aspect of teaching. The problem from which this research started is the high presence of violent behavior in primary schools in Zagreb. Therefore, the goal of this research was to find out how to encourage students' moral responsibility towards their peers and teachers by means of students' artistic expression. The results of the research answered the research question: To what extent is violence present in primary schools in Zagreb? What are the most common causes of violent behavior in primary schools? How to encourage students to offer ways of solving violence in their art and visual works? The research was conducted using the following methods: Quantitative, which started from the hypothesis - it was noticed that there is a high level of violence in elementary schools in Zagreb. The hypothesis was confirmed by the results collected by the following instruments: analysis of previous research, literature analysis, questionnaire for schools in Zagreb. Quantitative research determined the extent to which violence is present in primary schools in Zagreb and which forms of violence are most common. Through action research, it was determined that there would be possible solutions to the problem of violence. Students offered solutions to the problem of violence through artistic expression. The action research was conducted according to the descriptive model in a class community in an elementary school. The research instruments were: an interview with an art teacher; notes with observations of the causes and solutions of violence that the students indicated; artistic and visual works of students; photos of students' works. In the first action step, students did art work illustrating the causes of violence in schools. In the second action step, the students, using art, proposed possible solutions to the problem that would affect the cause recorded in the previous step. The usefulness of this research was finding possible ways to solve the problem of violence in elementary schools, offered by the students themselves. 91% of students from 5th to 8th grade admit that violence is present in their schools. 36% of students hear about violence sometimes, 16% often, and 10% always. 57% of students answered that they had witnessed violence in their school, while 32% of respondents stated that they were victims of violence. 14% of students come to school with the fear of violent behavior of their colleagues, 37% feel fear while staying at school, of which 16% regularly. The most common causes of violent behavior in schools, which were mentioned by students, are: bad education and problems in the family and school; dissatisfaction with oneself; people are insecure about themselves and therefore pass it on to other people; non-acceptance of diversity; discord in human opinions and beliefs. The students' answers pointed to unsatisfied needs for love and acceptance and self-esteem. The ways in which the students were encouraged to propose solutions to problems in their visual works are deductive and inductive research, collaborative learning (work in pairs and groups, brainstorming, graphic organizers), visual work with ready-made objects taken from the environment and presentation of their own visual work.
