When it’s taught right, learning math teaches you logic and how to organize your brain, how to take a problem one step at a time and make sure every step can bear weight before you move to the next one. Most adults don’t need to know integrals, but goddamn if I don’t wish everyone making arguments on the internet understood geometric proofs.
Scientific concepts broaden our understanding of how the world is put together, which does not mean that most adults ever really understand how light is refracted through a lens or why spinning copper wire creates electricity–and they don’t need to. But science classes in general are meant to teach the scientific method: how to make observations and use them to draw conclusions, how to test those conclusions, how to be wrong and grow stronger from it.
History isn’t about dates and names of battles, it’s about people, patterns, things we’ve tried before and ought to learn from. It’s about how everything is linked, how changing one circumstance can lead to changes in fifty others, cascading infinitely. Literature is about critical thinking, pattern recognition, learning to listen to what somebody is saying and decide what it means to you, how you feel about it, and what you want to do with it.
Some facts matter: every adult should know how to read a graph, how global warming works, some of the basic themes and symbols that crop up in every piece of fiction. But ultimately, content is less important later in life than context.
The good thing is, students who learn the content are likely to pick up at least some of the context, some of the patterns of thinking, even if they don’t realize it. (The unfortunate thing is how the current educational system prioritizes content so much that a lot of students, and a lot of adults, don’t see the point in learning either, and teachers are overworked and held to standardize test grading scales such that it’s hard for them to emphasize patterns of thinking over rote memorization, etc etc etc, but that is a whole different discussion.)
