Before reading too much into China's scores, there reason to believe there is selection bias in who they are testing. In 2017, applying the same rules to the US would have resulted in it shooting up to first and second place in some subjects, which shows that methodology has a bigger impact than what we actually want to measure.

- nopinsight 7y agoMath results of the best performing US state, Massachusetts, was actually 20th and 9th in the world for PISA 2015 and 2012, respectively, according to the links below. Moreover, MA's population of ~7 million is only ~2% of US population, whereas the four provinces' 180 million is about 13% of China's population. "for the Program for International Student Assessment, or PISA. It shows the state is tops in the country in math, but when you zoom out and look globally, Massachusetts ranks 20th in the world." https://www.wbur.org/edify/2017/04/10/massachusetts-math-education-workforce https://www.wbur.org/edify/2017/04/10/massachusetts-math-edu... "I found that if Massachusetts were allowed to report subject scores independently ... the Bay State would rank 9th in the world in Math." https://www.forbes.com/sites/jamesmarshallcrotty/2014/09/29/if-massachusetts-were-a-country-its-students-would-rank-9th-in-the-world/ https://www.forbes.com/sites/jamesmarshallcrotty/2014/09/29/... I think there should be a clear-eyed view toward China's progress in education as well as advanced research. For example, based on some measures of publications in top AI conferences, among the top 10 academic institutions in the world, 4 are in China, 4 in the US, and 2 in Singapore. http://csrankings.org/#/fromyear/2018/toyear/2019/index?ai&vision&mlmining&nlp&ir&world http://csrankings.org/#/fromyear/2018/toyear/2019/index?ai&v...
- cpitman 7y agoI think the population density was one of the points. The current system allows countries to pick the schools within a selected region, and in a high population region they can focus on top performing schools. > that the sampling done on mainland China (Beijing, Jiangsu, Guangdong and Shanghai) and other cities was not taken from a wide variety of schools. Rather, the very best schools were chosen and the very best students were cherry-picked from those schools. So this is more than just focusing on Massachusetts, this is picking only the best students from the best schools in Massachusetts.
