Now these are interesting regional patterns in terms science education and gender:
This visual is interactive so go click on the link above. It is interesting to see that the US is not the only Western country where boys score better than girls. Actually most Western European countries are the same category. On the other hand, see all the yellow dots on the right? Better test scores for girls in Eastern and Southern European countries as well as the Middle East. The same pattern applies to Asia and Pacific Islands.
Actually, it is almost exclusively in Western countries that boys lead over girls in these test scores. So, what’s wrong with Western countries? What is the big secret that Eastern and Southern Europe, the Middle East, Asia and Pacific Islands have discovered?
Also note the difference in scale between the “boys lead” side of the graph (from 0 to approximately 5 %) and the “girls lead” side of the graph (from 0 to almost 9%).
I am sure the explanation involves a multiplicity of interacting variables but I would still be interested to know whether someone actually did the research on this and figured out these variables and their impact. Unfortunately, the article does not really give an explanation.
