There’s a massive amount of duplicated effort in curriculum creation.
If the really gifted are documenting their lessons and publishing the framework other really good teachers can pickup where they left off.
Having those curriculums in a standard format would go a long way to making components interchangeable and remixable.
Just like in learn-by-doing, I believe some of it has to be done by the teacher themselves — by feeling where the pain is, they'll better focus on what matters.
Obviously, this starts mattering with more advanced education — not sure I can offer good insight for early education though :)
