Education is not about what is simply relevant. Learning the theoretical foundations of how our world works is important for everyone.<quoted text>
Might be more practical to teach high schoolers auto mechanics or how to use a debit card for those who will not become biologists or continuing on into the medical field. Teach them the scientific method of course. Theory will be irrelevant to the majority of them.
I would hope we don't need to teach students how to use a debit card.
And anyway, if you're not continuing on into biology and are so opposed to learning the theory, then don't take a biology class in high school.
