Whatever the field, as far as I know, students learn real science only when they start their PhD. Sometimes even later. I would love to see a real science course, where students come up with theories and discard them, again and again, until they come up with something probably correct (or not). That would teach them to accept being wrong (I hope). Today, it's hard to do for anything but open questions, which tend to be pretty difficult.
