If it's a disaster, why does the same curriculum work well for Asian Americans (raising their scores to east Asian levels), but badly for white Americans? First, it merely shows that when you select the highest performing group, you'll get a higher than average performance. Ok. What causes the variance between high and low performing groups? Since the school system seems the same, it doesn't seem to be educational techniques. Other factors can compensate for it, such as the known higher work ethic of Asian Americans and cultural valuation of intelligence and cognitive skills Correct me if I'm wrong, but you seem to be more or less agreeing with me here. Some trait which is very common among Asians appears to be the primary driver of test score deltas.
