I do not always know the answer or specific subject that a student needs to learn. Helping a student find the answer, access the necessary texts or other materials is more valuable than telling them the answer. I try to help students access all available texts, whether they are in libraries, or the internet, or elsewhere. We discuss the topic and I try to help them get a better understanding. As Noam Chomsky says in this video:
where to look, how to look, how to question, how to challenge, how to proceed independently to deal with the challenges that the world presents to you and that you develop in the process of your self education and inquiry and investigations in cooperation and solidarity with others. That’s what an educational system should cultivate.
