I think this model is wrong. The so-called understanding is a realized pattern matching that comes from deep memory of many things. I have a very good memory (I recall my car's VIN) and it mostly comes from practice at reading large volumes of material. Understanding came rapidly for me as I grew up - arising primarily from seeing repeated patterns. Isomorphisms are natural to pick up once sufficient data is shoved into the mind. I will try the same with my children. The real lack in the US is that most children here consume small quantities of information. The few who are pushed or permitted to push themselves succeed greatly.
