The topic of this thesis is Debate as a creative stimulus for the development of speaking skills in children of younger school age. As the name itself suggests, in this paper I will focus on encouraging debate in classes through its implementation. Offering the student the opportunity to develop his critical thinking and argumentation is extremely important. Therefore, the debate, as a structured and argumentative discussion about a predetermined thesis, encourages the student to state his position in an argumentative manner, respecting others'. It is important to point out that communicative competence is an important prerequisite for any form of discussion, i.e. it is important to know the structure of language and the principles of using these structures in different situations and activities. The aim of this paper is to make students of younger school age, as well as their teachers, aware of the importance of implementing debate in the teaching of the Croatian language. All important determinants of the debate are emphasized, which are presented at the end of this work and through the conducted research. The research was conducted at the Hrvatski Leskovac Elementary School from February 2 to February 8, 2024. Eleven fourth-grade students participated in the research, of which 54.5% were girls and 45.5% were boys, that is, six girls and five boys. The research instrument was a questionnaire composed of 23 statements that was given to the students before and after the three debates. Also, during the debate, the students' non-verbal communication between the two opposing sides was observed. The main goal of the research was to examine how much debate helps in the development of speaking skills of students of younger school age.
