My wife is Asian and our daughter did quite well in school. However any racial component was cultural rather than genetic. We set and enforced standards. School work came first and what was learned was more important than grades as grades are often inflated so all can “succeed”. No means no and yes means yes. You love your kid by helping them achieve their full potential. This used to be American every bit as much as Asian.
An interesting observation:
Americans of German ancestry in the Midwest and German school kids in Germany and Austria have roughly the same test scores. This comes in spite of the fact that German-Americans live on a different continent and no longer speak their native language.
How is it possible that kids who live in the same town, go to the same public schools, speak the same language, celebrate the same holidays, and sit in the same classroom and get the same homework from the same teachers manage to consistently produce such intractable differences in average test scores by ancestral group whereas their peers abroad - their cousins - are so remarkably similar?
How do you know it was cultural and not genetic? All of these “culture only” people seem to believe what they want and ignore whatever possiblities they don’t like. There is pretty surely both a cultural AND a genetic component. There is NO evidence denying that likelihood.
