For years, advocates for students in NYC have argued that using high-stakes tests on 4-year-olds to determine their school placement for the entire K-12 experience is unfair. It disadvantages students who didn’t attend academic-style pre-K or early enrichment programs.

Any test administered at age 4 will quickly cease to provide useful information, as students develop at different rates. Some accelerate during the elementary or high school years, while others who initially looked precocious settle into average achievement.

3. It limited which students fully realize their potential

But research shows that many students start the school year performing well above grade level and are left to become bored and not reach their full potential.

By failing students with advanced academic needs who come from underrepresented groups, New York City’s Department of Education risks losing the entire gifted program.

An overhaul is possible, but it has to start with evidence-based practices, not quick fixes.

transportation experts are scrambling to figure out how to better adapt public transit to the needs of riders as cities begin to emerge from the pandemic.

In India, a company that sells secondhand cars online saw sales swell in 2020 and its own value as a company jump to $1 billion, according to news reports. Elsewhere, bike sales have grown, suggesting that people are pedaling a bit more.

Both London and Paris sought to use lockdowns to expand bike lanes.

ridership was just over half of normal in the first two months of this year.

Most importantly, if transit systems continue to lose passenger fare revenues, they will not be able to make the investments necessary to be efficient, safe and attractive to commuters.

The city transit agency, which had once projected a budget surplus for 2020, has instead been relying on government bailouts since the pandemic hit.

The quality of mathematics research in the United States today is the envy of the scientific world. This is a direct result of the openness and inclusivity of the profession.

Can Americans maintain this unmatched excellence in the future? There are worrisome signs that suggest not.

The Organization for Economic Cooperation and Development compares mathematical proficiency among 15-year-olds by country worldwide. According to its 2018 report, America ranked 37th while China, America’s main competitor for world leadership, came in first.

This is despite the fact that the United States is the fifth-highest spender per pupil among the 37 developed OECD nations

This massive failure of our K-12 education system trickles through the STEM pipeline.

At the undergraduate level, too few American students are prepared for higher-level mathematics courses. These students are then unprepared for rigorous graduate-level work

According to our own experiences at the universities where we teach, an overwhelming majority of American students with strong math backgrounds are either foreign-born or first-generation students who have additional support from their education-conscious families. At all levels, STEM disciplines are more and more dependent on a constant flow of foreign talent.

There are many reasons for this failure, but the way that we educate and prepare teachers is particularly influential. The vast majority of K-12 math teachers are graduates of teacher-preparation programs that teach very little substantive mathematics

This has led to a constant stream of ill-advised and dumbed-down reforms. One of the latest fads is anti-racist mathematics. Promoted in several states, the bizarre doctrine threatens to further degrade the teaching of mathematics.

Another major concern is the twisted interpretation of diversity, equity, and inclusion (DEI).

Under the banner of DEI, universities are abandoning the use of standardized tests like the SAT and GRE in admissions, and cities are considering scrapping academic tracking and various gifted programs in schools, which they deem “inequitable.”

such programs are particularly effective, when properly implemented, at discovering and encouraging talented children from disadvantaged backgrounds.

The new 2021 Mathematics Framework, currently under consideration by California’s Department of Education, does away “with all tracking, acceleration, gifted programs, or any instruction that involves clustering by individual differences, without expressing any awareness of the impact these drastic alterations would have in preparing STEM-ready candidates.”

These measures will not only hinder the progress of the generations of our future STEM workforce but also contribute to structural inequalities, as they are uniquely detrimental to students whose parents cannot send them to private schools or effective enrichment programs.

These are just a few examples of an unprecedented fervor for revolutionary change in the name of Critical Race Theory (CRT), a doctrine that views the world as a fierce battleground for the narratives of various identity groups.

This will only lead to a further widening of racial disparities in educational outcomes while lowering American children’s rankings in education internationally.

Ill-conceived DEI policies, often informed by CRT, and the declining standards of K-12 math education feed each other in a vicious circle

Regarding minorities, in particular, public K-12 education all too often produces students unprepared to compete, thus leading to large disparities in admissions at universities, graduate programs, and faculty positions. This disparity is then condemned as a manifestation of structural racism, resulting in administrative measures to lower the evaluation criteria. Lowering standards at all levels leads eventually to even worse outcomes and larger disparities, and so on in a downward spiral.

A case in point is the recent report by the American Mathematical Society that accuses the entire mathematics community, with the thinnest of specific evidence, of systemic racial discrimination. A major justification put forward for such a grave accusation is the lack of sufficient representation of Black mathematicians in the professio

the report, while raising awareness of several ugly facts from the long-ago past, makes little effort to address the real reasons for this, mainly the catastrophic failure of the K-12 mathematical educational system.

The National Science Foundation, a federal institution meant to support fundamental research, is now diverting some of its limited funding to various DEI initiatives of questionable benefit.

Meanwhile, other countries, especially China, are doing precisely the opposite, following the model of our past dedication to objective measures of excellence. How long before we will see a reverse exodus, away from the United States?

The present crisis can still be reversed by focusing on a few concrete actions:

Improve schools in urban areas and inner-city neighborhoods by following the most promising education programs. These programs demonstrate that inner-city children benefit if they are challenged by high standards and a nurturing environment.

Follow the lead of other highly successful rigorous programs such as BASIS schools and Math for America, which focus on rigorous STEM curricula, combined with 21st-century teaching methods, and recruit talented teachers to help them build on their STEM knowledge and teaching methods.

Increase, rather than eliminate, tailored instruction, both for accelerated and remedial math courses.

Reject the soft bigotry of low expectations, that Black children cannot do well in competitive mathematics programs and need dumbed-down ethnocentric versions of mathematics.

Uphold the objective selection process based on merit at all levels of education and research.

For Coates, true equality means “black people in this country have the right to be as mediocre as white people,” he says. “Not that individual black people will be as excellent, or more excellent, than other white people.”

he came to see black respectability—the idea that, to succeed, African-Americans must stoically prevail against the odds and be “twice as good” as white people to get the same rights—as deeply immoral.

He is no soothsayer, telling people what to think from on high, but rather is refreshingly open about what he doesn’t know, inviting readers to learn with him. Coates is not merely an ivory-tower pontificator or a shiny Web 2.0 brand. He is a public intellectual for the digital age.

we miss the real question of why there is a systemic, historical difference in the way police treat blacks versus whites.

Another term for that road is “white supremacy.” This refers not so much to hate groups, but, as Coates defines it, a system of policies and beliefs that aims to keep African-Americans as “a peon class.”

To be “white” in this sense does not refer merely to skin color but to the degree that someone qualifies as “normal,” and thus worthy of the same rights as all Americans

The pool where all these ideas eventually arrive is a question: “How big-hearted can democracy be?” he says. “How many people can it actually include and sustain itself? That is the question I’m asking over and over again.”

it is a question of empathy. Are humans capable of forming a society where everyone can flourish?

there was the coverage of Michael Brown (or Jordan Davis, or Renisha McBride, or Eric Garner): unarmed African-Americans killed by police or others under controversial circumstances. In each case, the storyline was that these horrific encounters were caused either by genuine provocation, or by race-fueled fear or hatred. Either way, they were stories of personal failings.

When an event becomes news, there is often an implication that it is an exception—that the world is mostly working as it should and this event is newsworthy because it’s an aberration. If the race-related stories we see most often in the media are about personal bigotry, then our conception of racism is limited to the bigoted remarks or actions—racism becomes little more than uttering the n-word.

he cites research that in 1860 slaves were the largest asset in the US economy. “It is almost impossible to think of democracy, as it was formed in America, without the enslavement of African-Americans,” he says. “Not that these things were bumps in the road along the way, but that they were the road.”

a lack of historical perspective in the media’s approach to race. “Journalism privileges what’s happening now over the long reasons for things happening,” he says. “And for African-Americans, that has a particular effect.”

Even the very existence of racism is questioned: A recent study published by the Association of Psychological Science has shown that whites think they are discriminated against due to race as much if not more than blacks.

“So when you’re talking about something like institutional racism and prejudice, how do you talk about that as an objective reality?”

Coates’ strength is in connecting contemporary problems to historical scholarship. “I think if I bring anything to the table it’s the ability to synthesize all of that into something that people find emotionally moving,” he says. The irony of the reparations piece, as unoriginal as it may have been to scholars, is that it was news to many people.

Reporting on race requires simultaneously understanding multiple, contradictory worlds, with contradictory narratives. Widespread black poverty exists; so do a black middle class and a black president

Progress is key to the myth of American Exceptionalism, and the notion that America is built on slavery and on freedom are discordant ideas that threaten any simple storyline. Coates, together with others who join him, is trying to claim the frontier of a new narrative.

reading Coates is like building a worldview, piece by piece, on an area of contemporary life that’s otherwise difficult to grasp.

“To come and tell someone may not be as effective in convincing them as allowing them to learn on their own. If you believe you come to a conclusion on your own, you’re more likely to agree.”

It’s brave to bare yourself intellectually on the Web, and to acknowledge mistakes, especially when the capital that public intellectuals appear to have is their ability to be “right.”

Coates is equally demanding of his followers. Online he is blunt, and willing to call people out. He cares enough to be rigorous

despite being a master of online engagement, Coates insists he does not write for others, an idea he explained in a recent post: “I have long believed that the best part of writing is not the communication of knowledge to other people, but the acquisition and synthesizing of knowledge for oneself. The best thing I can say about the reparations piece is that I now understand.”

To him, it’s an open question whether or not America will ever be capable of fostering true equality. “How big-hearted can democracy be? It points to a very ugly answer: maybe not that big-hearted at all. That in fact America is not exceptional. That it’s just like every other country. That it passes its democracy and it passes all these allegedly big-hearted programs [the New Deal, the G.I. Bill] but still excludes other people,

In a 2010 post about antebellum America, Coates mentioned feminist and abolitionist Angelina Grimke. “Suffice to say that much like Abe Lincoln, and Ulysses Grant, Angelina Grimke was a Walker,” he wrote. “What was the Walker reference?” Rosemartian asked in the comments section. “Just someone who spends their life evolving, or, walking,” Coates replied. “Grant and Lincoln fit in there for me. Malcolm X was another Walker. Walkers tend to be sometimes—even often—wrong. But they are rarely bigots, in the sense of nakedly clinging to ignorance.”

one of the leading modelers, Gabriela Gomes, suggested the entire area of research was being effectively blackballed out of fear it might encourage a relaxation of pandemic vigilance. “This is the very sad reason for the absence of more optimistic projections on the development of this pandemic in the scientific literature,” she wrote on Twitter. “Our analysis suggests that herd-immunity thresholds are being achieved despite strict social-distancing measures.”

Gomes suggested, herd immunity could happen with as little as one quarter of the population of a community exposed — or perhaps just 20 percent. “We just keep running the models, and it keeps coming back at less than 20 percent,” she told Hamblin. “It’s very striking.” Such findings, if they held up, would be very instructive, as Hamblin writes: “It would mean, for instance, that at 25 percent antibody prevalence, New York City could continue its careful reopening without fear of another major surge in cases.”

But for those hoping that 25 percent represents a true ceiling for pandemic spread in a given community, well, it almost certainly does not, considering that recent serological surveys have shown that perhaps 93 percent of the population of Iquitos, Peru, has contracted the disease; as have more than half of those living in Indian slums; and as many as 68 percent in particular neighborhoods of New York City

overshoot of that scale would seem unlikely if the “true” threshold were as low as 20 or 25 percent.

But, of course, that threshold may not be the same in all places, across all populations, and is surely affected, to some degree, by the social behavior taken to protect against the spread of the disease.

we probably err when we conceive of group immunity in simplistically binary terms. While herd immunity is a technical term referring to a particular threshold at which point the disease can no longer spread, some amount of community protection against that spread begins almost as soon as the first people are exposed, with each case reducing the number of unexposed and vulnerable potential cases in the community by one

you would not expect a disease to spread in a purely exponential way until the point of herd immunity, at which time the spread would suddenly stop. Instead, you would expect that growth to slow as more people in the community were exposed to the disease, with most of them emerging relatively quickly with some immune response. Add to that the effects of even modest, commonplace protections — intuitive social distancing, some amount of mask-wearing — and you could expect to get an infection curve that tapers off well shy of 60 percent exposure.

Looking at the data, we see that transmissions in many severely impacted states began to slow down in July, despite limited interventions. This is especially notable in states like Arizona, Florida, and Texas. While we believe that changes in human behavior and changes in policy (such as mask mandates and closing of bars/nightclubs) certainly contributed to the decrease in transmission, it seems unlikely that these were the primary drivers behind the decrease. We believe that many regions obtained a certain degree of temporary herd immunity after reaching 10-35 percent prevalence under the current conditions. We call this 10-35 percent threshold the effective herd immunity threshold.

Indeed, that is more or less what was recently found by Youyang Gu, to date the best modeler of pandemic spread in the U.S

he cautioned again that he did not mean to imply that the natural herd-immunity level was as low as 10 percent, or even 35 percent. Instead, he suggested it was a plateau determined in part by better collective understanding of the disease and what precautions to take

Gu estimates national prevalence as just below 20 percent (i.e., right in the middle of his range of effective herd immunity), it still counts, I think, as encouraging — even if people in hard-hit communities won’t truly breathe a sigh of relief until vaccines arrive.

If you can get real protection starting at 35 percent, it means that even a mediocre vaccine, administered much more haphazardly to a population with some meaningful share of vaccination skeptics, could still achieve community protection pretty quickly. And that is really significant — making both the total lack of national coordination on rollout and the likely “vaccine wars” much less consequential.

At least 20 percent of the public, and perhaps 50 percent, had some preexisting, cross-protective T-cell response to SARS-CoV-2, according to one much-discussed recent paper. An earlier paper had put the figure at between 40 and 60 percent. And a third had found an even higher prevalence: 81 percent.

The T-cell story is similarly encouraging in its big-picture implications without being necessarily paradigm-changing

These numbers suggest their own heterogeneity — that different populations, with different demographics, would likely exhibit different levels of cross-reactive T-cell immune response

The most optimistic interpretation of the data was given to me by Francois Balloux, a somewhat contrarian disease geneticist and the director of the University College of London’s Genetics Institute

According to him, a cross-reactive T-cell response wouldn’t prevent infection, but would probably mean a faster immune response, a shorter period of infection, and a “massively” reduced risk of severe illness — meaning, he guessed, that somewhere between a third and three-quarters of the population carried into the epidemic significant protection against its scariest outcomes

the distribution of this T-cell response could explain at least some, and perhaps quite a lot, of COVID-19’s age skew when it comes to disease severity and mortality, since the young are the most exposed to other coronaviruses, and the protection tapers as you get older and spend less time in environments, like schools, where these viruses spread so promiscuously.

Balloux told me he believed it was also possible that the heterogeneous distribution of T-cell protection also explains some amount of the apparent decline in disease severity over time within countries on different pandemic timelines — a phenomenon that is more conventionally attributed to infection spreading more among the young, better treatment, and more effective protection of the most vulnerable (especially the old).

Going back to Youyang Gu’s analysis, what he calls the “implied infection fatality rate” — essentially an estimated ratio based on his modeling of untested cases — has fallen for the country as a whole from about one percent in March to about 0.8 percent in mid-April, 0.6 percent in May, and down to about 0.25 percent today.

even as we have seemed to reach a second peak of coronavirus deaths, the rate of death from COVID-19 infection has continued to decline — total deaths have gone up, but much less than the number of cases

In other words, at the population level, the lethality of the disease in America has fallen by about three-quarters since its peak. This is, despite everything that is genuinely horrible about the pandemic and the American response to it, rather fantastic.

there may be some possible “mortality displacement,” whereby the most severe cases show up first, in the most susceptible people, leaving behind a relatively protected population whose experience overall would be more mild, and that T-cell response may play a significant role in determining that susceptibility.

That, again, is Balloux’s interpretation — the most expansive assessment of the T-cell data offered to me

The most conservative assessment came from Sarah Fortune, the chair of Harvard’s Department of Immunology

Fortune cautioned not to assume that cross-protection was playing a significant role in determining severity of illness in a given patient. Those with such a T-cell response, she told me, would likely see a faster onset of robust response, yes, but that may or may not yield a shorter period of infection and viral shedding

Most of the scientists, doctors, epidemiologists, and immunologists I spoke to fell between those two poles, suggesting the T-cell cross-immunity findings were significant without necessarily being determinative — that they may help explain some of the shape of pandemic spread through particular populations, but only some of the dynamics of that spread.

he told me he believed, in the absence of that data, that T-cell cross-immunity from exposure to previous coronaviruses “might explain different disease severity in different people,” and “could certainly be part of the explanation for the age skew, especially for why the very young fare so well.”

the headline finding was quite clear and explicitly stated: that preexisting T-cell response came primarily via the variety of T-cells called CD4 T-cells, and that this dynamic was consistent with the hypothesis that the mechanism was inherited from previous exposure to a few different “common cold” coronaviruses

“This potential preexisting cross-reactive T-cell immunity to SARS-CoV-2 has broad implications,” the authors wrote, “as it could explain aspects of differential COVID-19 clinical outcomes, influence epidemiological models of herd immunity, or affect the performance of COVID-19 candidate vaccines.”

“This is at present highly speculative,” they cautioned.

It isn’t clear how the American public-school system will survive the COVID years. Teachers, whose relative pay and status have been in decline for decades, are fleeing the field. In 2021, buckling under the stresses of the pandemic, nearly 1 million people quit jobs in public education, a 40 percent increase over the previous year.

These kids, and the investments that come with them, may never return—the beginning of a cycle of attrition that could continue long after the pandemic ends and leave public schools even more underfunded and dilapidated than before. “It’s an open question whether the public-school system will recover,” Steiner said. “That is a real concern for democratic education.”

The high-profile failings of public schools during the pandemic have become a political problem for Democrats, because of their association with unions, prolonged closures, and the pedagogy of social justice, which can become a form of indoctrination.

The party that stands for strong government services in the name of egalitarian principles supported the closing of schools far longer than either the science or the welfare of children justified, and it has been woefully slow to acknowledge how much this damaged the life chances of some of America’s most disadvantaged students.

Public education is too important to be left to politicians and ideologues. Public schools still serve about 90 percent of children across red and blue America.

Since the common-school movement in the early 19th century, the public school has had an exalted purpose in this country. It’s our core civic institution—not just because, ideally, it brings children of all backgrounds together in a classroom, but because it prepares them for the demands and privileges of democratic citizenship. Or at least, it needs to.

What is school for? This is the kind of foundational question that arises when a crisis shakes the public’s faith in an essential institution. “The original thinkers about public education were concerned almost to a point of paranoia about creating self-governing citizens,”

“Horace Mann went to his grave having never once uttered the phrase college- and career-ready. We’ve become more accustomed to thinking about the private ends of education. We’ve completely lost the habit of thinking about education as citizen-making.”

School can’t just be an economic sorting system. One reason we have a stake in the education of other people’s children is that they will grow up to be citizens.

Public education is meant not to mirror the unexamined values of a particular family or community, but to expose children to ways that other people, some of them long dead, think.

If the answer were simply to push more and more kids into college, the United States would be entering its democratic prime

So the question isn’t just how much education, but what kind. Is it quaint, or utopian, to talk about teaching our children to be capable of governing themselves?

The COVID era, with Donald Trump out of office but still in power and with battles over mask mandates and critical race theory convulsing Twitter and school-board meetings, shows how badly Americans are able to think about our collective problems—let alone read, listen, empathize, debate, reconsider, and persuade in the search for solutions.

democratic citizenship can, at least in part, be learned.

The history warriors build their metaphysics of national good or evil on a foundation of ignorance. In a 2019 survey, only 40 percent of Americans were able to pass the test that all applicants for U.S. citizenship must take, which asks questions like “Who did the United States fight in World War II?” and “We elect a President for how many years?” The only state in which a majority passed was Vermont.

he orthodoxies currently fighting for our children’s souls turn the teaching of U.S. history into a static and morally simple quest for some American essence. They proceed from celebration or indictment toward a final judgment—innocent or guilty—and bury either oppression or progress in a subordinate clause. The most depressing thing about this gloomy pedagogy of ideologies in service to fragile psyches is how much knowledge it takes away from students who already have so little

A central goal for history, social-studies, and civics instruction should be to give students something more solid than spoon-fed maxims—to help them engage with the past on its own terms, not use it as a weapon in the latest front of the culture wars.

Releasing them to do “research” in the vast ocean of the internet without maps and compasses, as often happens, guarantees that they will drown before they arrive anywhere.

The truth requires a grounding in historical facts, but facts are quickly forgotten without meaning and context

The goal isn’t just to teach students the origins of the Civil War, but to give them the ability to read closely, think critically, evaluate sources, corroborate accounts, and back up their claims with evidence from original documents.

This kind of instruction, which requires teachers to distinguish between exposure and indoctrination, isn’t easy; it asks them to be more sophisticated professionals than their shabby conditions and pay (median salary: $62,000, less than accountants and transit police) suggest we are willing to support.

To do that, we’ll need to help kids restore at least part of their crushed attention spans.

staring at a screen for hours is a heavy depressant, especially for teenagers.

we’ll look back on the amount of time we let our children spend online with the same horror that we now feel about earlier generations of adults who hooked their kids on smoking.

“It’s not a choice between tech or no tech,” Bill Tally, a researcher with the Education Development Center, told me. “The question is what tech infrastructure best enables the things we care about,” such as deep engagement with instructional materials, teachers, and other students.

The pandemic should have forced us to reassess what really matters in public school; instead, it’s a crisis that we’ve just about wasted.

Like learning to read as historians, learning to sift through the tidal flood of memes for useful, reliable information can emancipate children who have been heedlessly hooked on screens by the adults in their lives

Finally, let’s give children a chance to read books—good books. It’s a strange feature of all the recent pedagogical innovations that they’ve resulted in the gradual disappearance of literature from many classrooms.

The best way to interest young people in literature is to have them read good literature, and not just books that focus with grim piety on the contemporary social and psychological problems of teenagers.

We sell them insultingly short in thinking that they won’t read unless the subject is themselves. Mirrors are ultimately isolating; young readers also need windows, even if the view is unfamiliar, even if it’s disturbing

connection through language to universal human experience and thought is the reward of great literature, a source of empathy and wisdom.

The culture wars, with their atmosphere of resentment, fear, and petty faultfinding, are hostile to the writing and reading of literature.

W. E. B. Du Bois wrote: “Nations reel and stagger on their way; they make hideous mistakes; they commit frightful wrongs; they do great and beautiful things. And shall we not best guide humanity by telling the truth about all this, so far as the truth is ascertainable?”

The classroom has become a half-abandoned battlefield, where grown-ups who claim to be protecting students from the virus, from books, from ideologies and counter-ideologies end up using children to protect themselves and their own entrenched camps.

American democracy can’t afford another generation of adults who don’t know how to talk and listen and think. We owe our COVID-scarred children the means to free themselves from the failures of the past and the present.

Students are leaving as well. Since 2020, nearly 1.5 million children have been removed from public schools to attend private or charter schools or be homeschooled.

“COVID has encouraged poor parents to question the quality of public education. We are seeing diminished numbers of children in our public schools, particularly our urban public schools.” In New York, more than 80,000 children have disappeared from city schools; in Los Angeles, more than 26,000; in Chicago, more than 24,000.
