Knowledge is constantly created and recreated. Nobody can know everything, as the corpus of knowledge is always in flux. How, then, can we go about providing any sort of comprehensive education?
Simply, we can’t. Instead, we have to be learners while we are teachers, and teachers while we are learners. Paulo Friere understands this, writing, “To teach is not to transfer knowledge, but to create the possibilities for the production or construction of knowledge” (“There Is No Teaching without Learning”). All those in a classroom (however defined) are both teachers and learners, collaborators in the production of knowledge.
The duty of teachers is not necessarily to impart knowledge, transmitting it from the instructor’s mouth to the students’ ears, but to draw out knowledge– to connect ideas with what already exists, to foster growth of new ideas.
