Most of the comments are focused on the supply of education. But I don't think the supply side is the problem, irrespective of teachers and high schools. There is more and cheaper education available than ever before. Nearly every highschooler has more access to learning that kings and emperors would have fought wars for less than 200 years ago. However,the United States, particularly in the last 50 years, seems to h…

The problem with that “culture” explanation is that white kids in America do fine in international educational comparisons. In the 2018 PISA assessment, 15 year old white american students were near the top in reading (behind only Singapore and some Chinese SEZs) and in the top echelon in science (comparable to Japan). Their weakest performance was math, where they’re around the middle, behind the top asian countries…

If you compare a country where most people are one ethnicity or where wealth and race are not as correlated as in the US, then it's a bit of an unfair comparison.

Does the comparison hold if you segment the white Americans, Chinese, Singaporeans, Japanese, etc. by economic class?

The majority of the public school system has devolved into day-care, not education. Most parents just watch TV, stare at their phones and don't want to be bothered by anything that requires effort. A major societal shift needs to happen for this to be reversed. It's many factors... the parents, the food system, various inequalities, social media, technology, healthcare... the solution is multi-pronged. But if I had t…

> The majority of the public school system has devolved into day-care, not education. I resisted that narrative for years, thinking it was just a media-hyped scare tactic to get clicks. However, my niece started high school a few weeks ago (in mid-August, which is weird to me); her experience blew my mind. Her new high school is considered one of the better public high schools in the area. When I asked her how it was…

Either this is a bizarre backwards school, or your niece is exaggerating for effect.

> kids in the US are doing active shooter drills and staring at the Ten Commandments. USA! USA! USA!

Not a thing at public schools (despite some attempts to force it)

Between this and the prayer comment, I suspect this comment is either exaggerated or mixed with internet anecdotes rather than actual experience.

Culture argument can be argued effectively as follows: If a cohort in Japan has a median score of X at median household income Y, the American cohort with same median score X has income closer to 1.25Y or 1.5Y. Whether you want to define your American cohort based on geography or ethnicity doesn't really matter-the result will be preserved up to a point.

That’s just because Americans are richer across the Board than Japanese. But would we expect PISA scores to track absolute income across different developed countries? I don’t think that follows. For example, Sweden’s median household income (PPP) is 2.6x higher than Poland’s. But the two countries had very similar scores on the 2018 PISA: http://hechingerreport.org/what-2018-pisa-international-rank...

I think one of the biggest factors comes down to single parent vs intact families.

Just look at HN. Nominally an educated crowd, but talk about physics, and you immediately see terms like "ivory towers" or "return on investment", despite the fact that most on HN doesn't understand in fundamental science works.

A lot of the complaints here about physics have to do with focusing so heavily for decades on string theory (or M-theory) which hasn't produced much in the way of practical results. At some point we have to quit throwing good money after bad and redirect funding towards other lines of inquiry.

Is the purpose of life purely to seek a monetary return on investment?

Is the purpose of theoretical physics purely to seek mathematical innovations with no connection to objective reality?

The racial achievement gap is probably one of the most significant problems educators in the US think about. I think one of the biggest obstacles to improving it (not causing the problem, but making solutions difficult or ineffective) is that low-performing urban school districts tend to correlate strongly with strong teachers' unions and big, mismanaged school administrations where things are too bureaucratic and in…

At least near me the biggest problems facing the "urban" district compared to suburban ones is declining student populations as long time homeowners age in place and the maintenance costs of 100 year old buildings compared to 10-20 year old ones in the suburbs. Teachers tend to get paid the same or less in the city district and administration counts are higher but fairly close on a per student basis compared to the b…

Wouldn't a declining student population mean more money per student? And it seems like it would often (but not always) be cheaper to maintain existing buildings vs building new ones? I'm also wondering how much of the new suburban buildings are financed with debt, and the costs just haven't really caught up to them yet.

I doubt much changed. American STEM education has always been pretty mediocre. I've been hearing about my whole life.

Mediocre by what metric? American STEM education seems to objectively be doing pretty well in terms of Nobel prizes, scholarly journal articles, patents, technology product revenue, etc. Of course there's always room for improvement.

> American STEM education seems to objectively be doing pretty well in terms of Nobel prizes, scholarly journal articles, patents, technology product revenue, etc.

I hate to break it to you, but a lot of our most valuable research is produced by people who did their primary education outside the US. Just go to a STEM research lab at any US university connected to a Nobel prize or Fields medal in the last 10-20 years, and it will be almost completely made up of internationally educated students / professors / etc.

This isn't a culture argument or even a sound/good argument for anything. Americans are just wealthier and you can't compare like that.

When you compare groups of students within the same country and adjust for both household income and intelligence you find that (again, even within the same intelligence brackets and income levels) some ethnic groups simply study more while others spend more time on things like unprovoked violence.

It’s culture led by phones and other screens. Most teens are addicted to the screens. The need them for school and for socialization with friends and they end up on TikTok or another network and zombie there for most of their best brain years. They lack the ability to focus necessary to learn because the brain is used to constant screen simulation. Letting your child be babysat by a screen is absolutely the worst thi…

I'm pretty sure the same argument was made for television, movies, radio and fiction books.

And? Maybe those things had an impact also? And maybe this is the last straw our backs can bear?

Like if you take a bunch of steps running from a road to the edge of a cliff, only after the last one over the edge do you experience all the problems

> However,the United States, particularly in the last 50 years, seems to have fostered a culture averse to education. I always find it interesting that the anti-schooling mentality is so prevalent here on HN, too. It’s most obvious in threads about cheating, where a popular topic of discussion is to defend cheating as a rational reaction because school doesn’t matter, a degree is “just a piece of paper”, and you’ll l…

I noticed a weird disdain for education too.

I once posted in support of general education and it didn’t go so well.

I suppose the people on HN are a certain demographic.
