The paper covers the concepts of optimal classroom atmosphere, discipline, classroom management, teaching authority and the use of teaching strategies and methods in classroom management and discipline in the classroom. All of the above concepts should be considered in a relationship that in a sense is a dependent line of these concepts, where no item can be observed separately if we take in consideration one classroom with students. The teacher's authority cannot be observed without effective classroom managing or classroom management, supplemented by certain rules of conduct and discipline. Everything is perceived through the prism of the methods and strategies that teachers use to effectively manage the classroom and establish a solid and credible authority. It is important for the teacher to achieve balance and harmony in maneuvering the establishment of authority and the pursuit of discipline in the classroom and to adopt methods and techniques that will be effective in practice. Since these concepts are very important for teaching praxis, the qualitative research of elementary school teachers in Zadar (grades 5 through 8) has been conducted in order to establish a teacher's opinion regarding classroom management, discipline, authority, and which methods teachers used to establish discipline in the classroom. Ten teachers participated in the survey, where teachers responded to questions in the form of a semi-structured interview. By conducting research, it was found that teachers use certain methods in setting up a discipline, such as setting behavior rules, warning, interrogating, discussing with the student, or the method of praise or punishment. Teachers also consider the factors of certain students inappropriate behavior manifestation, encouraging students to participate in drafting rulebooks and making decisions in the classroom as well as a democratic leadership style. The purpose of the paper is to see how effective methods are used by teachers in classroom management and to highlight and provide guidelines for improving certain teaching approaches in classroom teaching and guidance.
