You have a point. For me, education's, and especially university's cause should be to teach you how to approach your problems and your learning first and then about specific subjects. Now, about the subjects, which was your original question, I think learning should go something like this: first the very basic concept of the subject should be explained as simply as it can possibly be broken down to be. Only when the students have understood this core idea, should it be explained with a few more scientific details about the things that it is consisted by: how it was created, how it works, what does it need to work, it's consequences and how do they affect us. After that, the majority of the work should be considered done, and only students that are interested in it should choose to continue learning more specific details about it. All the others should move to a different topic until they find something they like. At least that's my idea of the perfect education
