In this overview study, we would like to present the basic constructivist approaches that have affected or influenced the current concept of education. The teacher-student interaction is reflected by personality, psychological traits, attitudes and cultural capital of the participants of the educational process as well as the teacher's effort to mediate the didactic content to the students. Concerning the changing roles of the teacher and the student, which is followed by a concept based on pedagogical constructivism, it is also important to accept the need for adequate training of undergraduate teachers and further education of teachers in practice. The present discourse analysis will focus on the implementation of constructivist theory in educational theory and didactics.
