These questions represent an act of mental violence against educators who have been engaged in acts of mental violence against children since the introduction of compulsory education. Students should not accept subject matter that has been taken out of its natural context. Mathematics, for example, should never be taught as a study of isolated numbers and formulas. Mathematics should be taught while building a boat or constructing a house where it is used in its natural context. Educators take subject matter out of its natural context and then expect students to figure out how and where that subject matter will fit into their lives.
Students have to try to put the subject matter back into context inside of their own heads.
This is done, of course, after students have been taken out of their homes and away from natural physical reality, and have been isolated in classrooms where they have no opportunity to learn how any school subjects fit into a natural context. For example, high school students who are required to take a chemistry course should not have to figure out in their beads how chemistry will be useful to them someday. Even high school students who want to become physicians some day and who might use chemistry in their lives should study chemistry only in the context of learning how to become a physician. High school students should not have to take courses that are not directly relevant to their life plans. A high school student who wants to become a physician should already be involved in direct patient care in some way.
