The vast majority of academia currently employs the 'banking model' of education. Knowledge is conceived as a big pile of data that students need to absorb and then spit back out onto their exams, tests, and essays.
However, knowledge can be thought of in other ways. Knowledge can be transformative, and rather than 'training' people, it can be a genuine exchange between people. It's hard for a lot of academics to appreciate this approach because it doesn't seem to serve a function. You won't get hired as a dentist because you learned to think critically.
Critical thought and progressive pedagogy is crucial for the future. We need to find ways to be more creative and to demolish power imbalances. Students can go through all of elementary, high school and even university without ever having to think critically about racism, sexism, poverty, colonialism, heterosexism or homophobia.
Thinking about these things is problemetic if we use the banking model, because it's often not a question of getting MORE knowledge. It's about questioning our assumptions and examining the knowledge we've already received, and the ways we come to know about things. bell hooks wrote a great book on this topic called Teaching to Transgress; check it out if you're interested
If we don't start practicing progressive pedagogy in academia, we will continue to be unable to confront oppression except through ineffective policy. Academia is great at producing knowledge that tells governments, corporations, or 'the world' what to do. It's not so great at grappling with the same issues at the personal or group level. What's needed is alternatives that transform us and force us to think about how WE fit into these problems and what WE can do about them.
