alt Hacker NewsA kindergarten science education person suggested their kids have a human right to understand their world then, rather than a lifetime (for them) later. So atoms, etc.
I think that far far harder than they thought - "adapt later material for a younger audience" vs "wield lots and lots of research community domain expertise to craft largely novel content".
But I've found it an interesting probe question: How would you teach some domain differently, if you primarily cared about... what to call it... non-deferred epistemic agency and calibrated/unfiltered sense-making? No learning linear systems without learning how to do linear approximation of systems in a mostly non-linear world. Ideal Gas Law chapter questions still have numbers for solid argon, but the intended learning outcome is "nope!" not mindless "PV=nRT!". No "this course will leave you with lots of new misconceptions about the world, but we'll clean those up in later years for those who stay with us".

That's why Common Core trains kids on estimation from Grade 2. Instead of adding 12 + 23 = 35, you add 10 + 20 = 30 to get a number close to the right answer.
This plants the idea "I can simplified numbers to get the answer if I don't need the last digit, which lets me solve problems faster". Which gets generalized as "I can use the simplified Ideal Gas Law to model a complex system if I don't own a supercomputer".
Even in university I had this: my physics course heavily emphasized properties of linear systems to demonstrate why I'd want to use one and we ran linear regressions in other courses if we didn't "know" the true equations.
