To promote democratic interactions between people, Freire suggests that teachers problematize the issue being discussed.  When issues or questions are problematized by teachers who work through critical pedagogy, readily made answers are not available.  Students realize that although some questions do have clear-cut answers, many of our deeper questions do not have obvious answers.  When students learn that teachers are human beings just as everyone else, and that teachers do not know everything but that they are also learners, students then feel more confident in their own search for answers and more comfortable to critically raise questions of their own.  The banking method denies the need for dialogue because it assumes that the teacher is the one who possesses all the answers and the students are ignorant and in need of the teachers’ knowledge. In order to problematize a subject, the teacher assumes a humble and open attitude.
