"Boo, that's not fair to say. From which media source was it taken?"
Oh that's from the very same source that very fairly tells us nearly every day that all our children are absolutely rubbish at everything including the chunking, all teachers are blobby Marxist slackers in thrall to their unions, we must hand over state assests to their friends and financial backers [presumably so they can stuff yet more tax-payers money in off-shore accounts] and that yet another country has the solution to all our woes.

So the new fashionable exemplar is top-table Shanghai, a quite special part of a rather blobby nation which ermm.. has more than a passing association with Marxism. That they top the league tables is akin to skimming off the results from Kent's grammar schools and calling that entirely representative of England.
Follow my earlier link to that Tom Loveless trilogy of articles re. Shanghai and PISA. Go read about the effect of the language on maths (the Welsh apparently have it worst). Seek and you will find lots more to tell you what happens in school is only a fraction of the story there, but that's also a universal truth i.e. we hugely over-state the influence of schools and teachers on outcomes. Still I suppose it all keeps enough people scared and thus paying for private education, tutors and the like.
Also contemplate why we do well enough in TIMSS maths but not so well on PISA maths. You have to look at real questions for that research to work effectively and I trust that any competent secondary maths teacher who has done the same will agree that TIMSS is more direct school-stuff whereas PISA is tilted towards comprehension with it's little stories and multi-step problems. If we want league-table success we could decide to teach to PISA style maths-literacy at the expense of this or that (I wouldn't miss some of the flowery literary analysis or teaching children to write acres of empty prose on the off-chance they get a job in marketing), but then we might end up like another top-table country Finland where if you look closely you can find people whispering about the cost of their success in PISA maths, the Peter behind the Paul.
I really don't care whether people agree with me about the complexity behind the simplistic, trite headlines, but surely we're not so credulous to believe that is isn't complex and a few Chinese teachers spending a little time in a few of those schools with the ambitious celebrity HTs will make a difference?
