"I have suggested that our educational systems (both in the USA and in India) are in a real mess - and that the 'stakeholders in the system' don't have a clue about how to 'clear up' that mess. (Again, my apologies for using that much-disliked term "stakeholders" - I'm unable to find another suitable one that 'encompasses' the group I need to describe). "
You're comparing a train wreck to our attempt to fine tune a Boeing 777 which is actually flying at almost the speed of sound. There's nothing either country can learn from such a comparison. Even if anybody in India ever thought OPMS could gain a 1 point increase in your PISA math score, from 321 to 322 (still 5 points lower than Kyrgyzstan), the odds are less than zero that it could be applicable to any country with a score 2 standard deviations higher, like the US, much less a school system which scores 3 standard deviations higher, like Shanghai.
It certainly could make perfect sense to you in India to try this. And it might even make sense to the 80% who apply to CUNY who are illiterate, or the 99% in Highland Park who are illiterate, but the ROW already knows that if we ever were to adopt it, it would be even worse than NCLB.
