I am not sure which StackExchange to ask this question but I am interested in the relative underperformance of Western countries such as Australia, US, UK compared to other higher performing countries in the world. More specifically whether there are specific areas of mathematics of underperformance that have been discussed or highlighted before.
The PISA testing results that I have found online are very broad and generic but does not break down into the usual specific areas of maths for example, like this report from the OECD.
I am aware that another test TIMSS is problematic when comparing the "West" versus the rest but I wonder if there are specific subjects areas that are linked to underperformance rather than a general pedagogical approach issue.
