So you're going w/ B) A subtle entreaty to focus the brunt of America's educational efforts on specific ethnic subgroups so that the entire nation can have better results. The upside is that it's possible that whatever procedural improvements are made will probably improve all of the student body, so it's a win-win!
Unless, of course, you're also positing that these sub-groups can't be taught??
Unless you can demonstrate that this is cost effective, I'm certainly not.
And yes, I do generally posit that most educational interventions are ineffective. If you disagree, please point to one which can reliably and scalably increase the score of any group by an amount proportional to the black/white (or white/asian) gap.
So are you saying that the current methods of education can't be improved?
I'm not referring to an intervention, which, like dieting, will not be useful in the long term. I'm giving you credit for hitting upon the idea that education itself can be altered in a manner which is not only far more effective, but evenly distributed improvements across all tested populations.
That's a great idea, and we all look forward to hearing of your progress in this endeavor.
