Freire describes the traditional "banking" model of education as problematic because it treats students as empty vessels to be filled by the teacher. He argues this approach does not truly educate students and prevents them from developing their own ideas. Freire proposes an alternative "problem-posing" model where both teachers and students learn from each other through dialogue. In this model, students are active participants in their education rather than passive recipients, allowing them to gain a deeper understanding of concepts and relate learning to real life. Freire believes this approach better facilitates true knowledge and liberation of thought.
