Men score better than women on standardized tests in math in some countries, while in other countries women score better (http://www.econ.ucsb.edu/~kelly/gap_sept09.pdf).

It's almost as if the culture you are surrounded by somehow affects you. In fact the countries with more gender equality that encourage women in the sciences have higher test scores for women!

Thanks for that link. After looking through Appendix Table 2 (page 25), it's pretty obvious that the only big outlier is the gap in Israeli high-school students.

Here's a link to the (gated) paper with the data: http://www.sciencedirect.com/science/article/pii/S0047272708...

From the abstract:

  This paper tests for the existence of gender stereotyping and
  discrimination by public high-school teachers in Israel.
  
  Using data on test results in several subjects in the humanities 
  and sciences, I found, contrary to expectations, that male
  students face discrimination in each subject. These biases
  widen the female–male achievement difference because girls
  outperform boys in all subjects, except English, and at all levels of
  the curriculum. The bias is evident in all segments of the ability and
  performance distribution and is robust to various individual controls.

Ok, that was surprising. Does anyone have any more information about this?

Sure, if "gender equality" is a euphemism for school grades being biased towards girls:

“If, as the data suggest, young girls display a more developed ‘attitude toward learning’ and teachers (consciously or subconsciously) reward these attitudes by giving girls higher marks than warranted by their test scores, the seeds of a gender gap in educational attainment may be sown at an early age, because teachers‘ grades strongly influence grade-level placement, high-school graduation and college admission prospects.”

Wow, I never knew that the male-female Math gap was so robust. Look at the tables in the last three pages you linked. Except for Israel, nearly every country has a male-biased Math score gap on standardized tests.

It's called progressive-splaining [1]:

A condescending, inaccurate explanation delivered with rock solid confidence of rightness and that slimy certainty that of course they are right, because the are the progressive in this conversation
