My Hero Academia 3: Villainous Interlude

[Ramza00]

Zone of Proximal Development. At certain ages a Bird can't fly, but at other ages Birds can fly.

And with the ages that a bird can fly, some of the time it is so natural and effortless like breathing but before the bird gains this level of skill flying was possible but it was still hard to perform.

Humans are the same way with learning skills, for example we can't crawl until a certain age, eventually we can stand up right and balance followed by walking.

Later skills (which the Zone of Proximal Development is all about) we must learn via instruction and we may figure out the skill set without instruction but via mimesis aka watching others, and via diegesis aka corrective narrative feedback of what we did wrong and what to do next time we can accelerate and learn things at a more rapid pace, and some skills we could never learn without the "superstructure" without the "prosthesis" that teaching and instruction provide.

What are the purpose of these heroes schools that start training at 15? And were there any instructions of quirk use from age 5 to 15 besides "counseling" telling a kid there life is going to be somewhat different compared to when the quirk first manifests at roughly 5?

Choosing quirk manifestation to happen at around 5 and at around 15 implies automaticity arguments about how automatic the utilization of quirk factors and other aspects of quirks are.
