actors of Developing Interest in Subjects from the Perspective of Students

Using a descriptive method, through an essay test, students' interests in subjects were explored, with the aim of improving the educational process. The results show that students develop situational and individual interest in subjects, predominantly due to the personality of the teacher who competently processes teaching contents, directly and indirectly encourages students to participate, achieves a positive relationship with students, contributes to a pleasant atmosphere. The development of interests is also influenced by the profit that students perceive for their own development, everyday life and further education; content of a specific subject; achieved a positive achievement. Possibilities for influencing the more intensive and wider development of students' interest in subjects are: introduction of continuous formative evaluation of teaching and learning, systematic instructive-pedagogical work; compulsory public lessons; regular control and instructional-pedagogical tour of classes; inclusion of training of pedagogical and methodological education in the portfolio of continuous professional development of teachers; choice of forms and methods of work that encourage active participation of students, with the inclusion of interesting, current examples of importance for everyday life and creating an opportunity for positive achievement of students.
