Paulo Freire was a Brazilian educator who developed critical pedagogy. He was born into poverty and experienced hunger as a child due to the economic impacts of the Great Depression on his family. This influenced his view that education should empower the oppressed and poor. He argued that teaching should reject the "banking system" where students are treated as empty accounts to be filled by teachers. Instead, it should recognize that students have their own knowledge and life experiences. The goal of education, according to critical pedagogy, is to lessen human suffering and promote justice and equality.
