The ultimate goal of all education is, or at least ought to be, to teach the individual how to learn. In my mind, what they learn is less important than that they learn how to learn. why? Because if you know how to learn, there is no limit to what you can learn!
Not only is there no limit to what you can learn, but you will have the skills to teach yourself what you need to know. Part of that process, at least in my mind, is learning how to question what you see or hear, to challenge your own assumptions, and to have a desire to seek out answers to the questions you have.
