I attended a (public) middle school teacher meeting about two years ago. The 8th grade math teacher said "I am supposed to be teaching XYZ for the 8th grade statewide standardized math test. I can't do it. Around 1/3 of my students can't multiply two numbers. They don't know." (She went on in this vein--it wasn't laughing or flippant, it was a cry for help)

She didn't say 1/3 of her students struggled with some of their multiplication tables, or algebraic concepts, it was that they literally didn't know how multiplication works.

I used to quiz my kids every morning with short "head math" problems starting in K and 1st grade. I started simple "2+2" .. "5+5" ... "6+7". Eventually I added multiple steps "1 + 4 + 3 - 2" or "6 + 7 - 2 + 10". I did the same starting in maybe 3rd / 4th grade with multiplication tables.

One of my kids ended up being an academic high flyer. The other still, to this day, struggles with math. He somehow worked his way into an advanced math class, but he has to work his ass of in there for Bs and Cs.

I am very sympathetic to people who aren't mathematically inclined, but these problems are embarassingly easy.

So I have a serious question for you (this comes on the heels of me doing a deep dive on PISA testing results, and it honestly has been weighing heavily on my mind lately).

I 100% believe that socioeconomic factors are probably the single biggest factor in academic success.

Is there any possibility that average population-wide genetics play a role in academic success? (I very much do NOT want to use the word "race" because I think it's basically meaningless). Is it possible that, on average, Americans with a large Far East Asian genetic component perform academically better than, on average, American students with primarily Western European backgrounds? What about those with large sub-Saharan African genetic components? Etc.

The question really is--is it _possible_?

My answer is that yes, I think it's possible. I don't think academic achievement is the most important thing out there, but it's important.

And, if it's possible? What the heck do we, in a free and democratic society do about it?

It's bleak and dystopian to think about!

My oldest son goes to a high school on the other side of the country. It has an award winning Engineering magnet program. Every year multiple students from this school go to Ivies and other top 25 schools.

Simultaneously, ~55% of the school is poverty level, ~45% is low English proficiency, and about 30% of the students are considered habitually absent (meaning a minimum of 10 _unexcused_ absences).

My son is taking APs, very intensive engineering classes, and participating in multiple extracurricular activities.

In the same school building, more than half of the students regularly rank in less than the 30th percentile on both math and English end of grade tests.

What I commonly hear from teachers and administrators--if you're a teacher teaching classes of the poverty level non-English speakers, what good does it do to fail them? They're just going to drop out anyway. Maybe if you encourage the kids along, a few will get something out of it?

It's an awful situation to be in. The school has at least a dozen ELL teachers. The school offers pretty much all the standard freshman courses (English, US History, etc) in both Spanish and English versions. This drains so many resources from other parts of the school. The arts program operates on a shoestring and all the arts programs are constantly fundraising to keep the lights on.

The soccer team is damn good, though..

So everyone and everything is to blame except removing standardized testing as an admission criteria in California (2021), schools in CA being closed for in-person education for ~2 years due to Covid, and perhaps most importantly, California adopting a a radical new math curriculum that focused on equity and removing cultural barriers in math education. (See, e.g., EdWeek

Right, it's Republicans (all those nasty California Republicans who dominate state and local governments) that have put us in this mess!

Also, good for Homie the Clown from Living Color TV show.

... was how to disable it.

... please bring it back! I don't like huge and heavy iPhones!

I remember back in the 90s, search engines' web site(s) [don't remember which one(s)] used to show what people were searching.

imagine how many more thousands they could save by replacing 200k in toy computers with a real datacenter platform.

Or if it's even still readable. Intel when retrieving the 486 tape-in for the Edison project had to bake the tapes in an oven to remove moisture, and then had ONE CHANCE at imaging the tape as it crumbled to dust going through the reader.

Err, second half got weird and cool. Second episode was decent, but not good as the first.

... First half was slow, but the second episode got weird and cool. I am on its second episode. I think I will like it.

This would be perfect to sell for the movie's sequel!
