Good point. Now that you say it, I can see that we tend to rush kids through the basics to get to those higher levels and I had not thought baout how that can hurt people ever really getting the basics down.
But you just described one of the major reasons i think this focus on having the best math and science test scores (or even better than we have now--which is still pretty dang good, really 14th in the WORLD is not shabby) is bad. The focus is so strongly centered on math and science and only those things that there is less and less opportunity for kids to find out about those other things like poetry that they might excel at if exposed to them.
I think there's a lot of STEM talk for a couple of reasons.
First, because we're so far behind it's shocking. Fourteenth in the world is horrific when you consider that the U.S. is one of the richest countries in the world, with a national education system, the infrastructure to support education, etc. There aren't that many nations that SHOULD be competing at that level. I mean if you just say 'hey, there are 200 or so countries in the world and we rank 14th!' that sounds good. If you say there are 20 or 30 or so nations that could realistically be on the same level (as there are more places than not that just do not have the money, infrastructure, etc.), and we're 14th despite being in the top five or so probably when it comes to $$, it doesn't sound not too bad anymore imo.
Second, it's hard to compare other types of knowledge across nations. You can globally rank kids if you're measuring their ability to do algebra. Algebra is what it is, no matter where you grew up or what language you speak.
History, however, is harder to rank in terms of knowledge because the base isn't the same. I certainly took world history in h.s. and while I have some knowledge, I don't know the history of, to stick with a theme, Indonesian politics, any more than the average Swede would probably be able to name the U.S. Constitutional amendments or tell you what the Monroe Doctrine was.
In addition, as the world depends more on various forms of technology, and as populations grow, STEM becomes more important.
I'll add that I dunno where social studies etc., are being cut, but I think art is in a different category. I'm all for art education and practical art being done in schools, but I wouldn't sacrifice math class for it.
I also agree there's not, perhaps, enough focus on mastering fundamentals in some places but that's part of what a focus on this stuff is supposed to correct - making sure kids have the correct knowledge at all levels.
