Dialogue based educational approach, which was put forward by Paulo Freire (1921 – 1997), one of the most significant thinkers of radical education approach, was designed in such a way to enable teachers and students to carry out research together. Freire proposes this educational approach as an alternative to the traditional educational model which he calls as banking education. Therefore, the criticism of the banking model of education by Freire is provided in the first place in the study. The central concept in the educational model put forward by Freire is dialogue. Dialogue also constitutes the main concept of this study. Therefore, the study comprehensively focuses on the concept of dialogue, which is one of the techniques to be used in problem posing education according to Freire. As Freire emphasizes, dialogue is not only an educational technique, but also a style of confrontation that is peculiar to humans and must be used by all humans. Considering this fact, the concept of dialogue was examined in both dimensions in this study.
