As US Schools Prioritize Diversity Over Merit, China Is Becoming the World’s STEM Leader

All three of us are mathematicians who came to the United States as young immigrants, having been attracted by the unmatched quality and openness of American universities. {snip}

The United States has been dominant in the mathematical sciences since the mass exodus of European scientists in the 1930s. Because mathematics is the basis of science—as well as virtually all major technological advances, including scientific computing, climate modelling, artificial intelligence, cybersecurity, and robotics—US leadership in math has supplied our country with an enormous strategic advantage. But for various reasons, three of which we set out below, the United States is now at risk of losing that dominant position.

First, and most obvious, is the deplorable state of our K-12 math education system. Far too few American public-school children are prepared for careers in science, technology, engineering, and mathematics (STEM). This leaves us increasingly dependent on a constant inflow of foreign talent, especially from mainland China, Taiwan, South Korea, and India. In a 2015 survey conducted by the Council of Graduate Schools and the Graduate Record Examinations Board, about 55 percent of all participating graduate students in mathematics, computer sciences, and engineering at US schools were found to be foreign nationals. In 2017, the National Foundation for American Policy estimated that international students accounted for 81 percent of full-time graduate students in electrical engineering at U.S. universities; and 79 percent of full-time graduate students in computer science.

That report also concluded that many programs in these fields couldn’t even be maintained without international students. In our field, mathematics, we find that at most top departments in the United States, at least two-thirds of the faculty are foreign born. (And even among those faculty born in the United States, a large portion are first-generation Americans.) Similar patterns may be observed in other STEM disciplines.

The second reason for concern is that the nationwide effort to reduce racial disparities, however well-intentioned, has had the unfortunate effect of weakening the connection between merit and scholastic admission. It also has served (sometimes indirectly) to discriminate against certain groups—mainly Asian Americans. The social-justice rhetoric used to justify these diversity, equity, and inclusion (DEI) programs is often completely at odds with the reality one observes on campuses. The concept of fighting “white supremacy,” in particular, doesn’t apply to the math field, since American-born scholars of all races now collectively represent a small (and diminishing) minority of the country’s academic STEM specialists.

Third, other countries are now competing aggressively with the United States to recruit top talent, using the same policies that worked well for us in the past. Most notably, China, America’s main economic and strategic competitor, is in the midst of an extraordinary, mostly successful, effort to improve its universities and research institutions. As a result, it is now able to retain some of the best Chinese scientists and engineers, as well as attract elite recruits from the United States, Europe, and beyond.

In a 2018 report published by the Organization for Economic Cooperation and Development (OECD), China ranked first in mathematical proficiency among 15-year-olds, while the United States was in 25th place. And a recent large-scale study of adults’ cognitive abilities, conducted by the National Center for Education Statistics, found that many Americans lack the basic skills in math and reading required for successful participation in the economy. This poor performance can’t be explained by budgetary factors: When it comes to education spending per pupil, the United States ranks fifth among 37 developed OECD nations.

There are numerous underlying factors that help explain these failures—including some that, as mathematicians, we feel competent to address. One obvious problem lies in the way teachers are trained. The vast majority of K-12 math teachers in the United States are graduates of programs that teach little in the way of substantive mathematics beyond so-called math methods courses (which focus on such topics as “understanding the complexities of diverse, multiple-ability classrooms”). This has been true for some time. But the trend has become more noticeable in recent years, as curricula increasingly shift from actual mathematics knowledge to courses about social justice and identity politics.

An even bigger problem, in our view, is that the educational establishment has an almost complete lock on the content taught in our schools, with little input from the university math community. This unusual feature of American policymaking has led to a constant stream of ill-advised and dumbed-down “reforms,” which have served to degrade the teaching of mathematics to such an extent that it has become difficult to distinguish a student who is capable from one who is not.

Those who find that last assertion difficult to accept should peruse the revised Mathematics Framework proposed by California’s Department of Education. If implemented, the California framework would do away with any tracking or differentiation of students up to the 11th grade. In order to achieve what the authors call “equity” in math education, the framework would effectively close the main pathway to calculus in high school to all students except those who take extra math outside school—which, in practice, means students from families that can afford enrichment programs (or those going to charter and private schools). {snip}

{snip}. The new goal is to eliminate disparities in representation by any means possible. This is why education officials in some school boards and cities—and even entire states, such as California and Virginia—are moving to scrap academic tracking and various K-12 gifted programs, which they deem “inequitable.” Operating on the same motivations, many universities are abandoning the use of standardized tests such as the SAT and GRE in admissions.

This trend, which reaches across many fields, is especially self-defeating in mathematics, because declining standards in K-12 math education are now feeding into a vicious cycle that threatens to affect all STEM disciplines. As already noted, low-quality K-12 public-school education produces students who exhibit sub-par math skills, with underprivileged minorities suffering the most. This in turn leads to large disparities in admissions at universities, graduate programs, faculty, and STEM industry positions. Those disparities are then, in turn, condemned as manifestations of systemic racism—which results in administrative measures aimed at lowering evaluation criteria. This lowering of standards leads to even worse outcomes and larger disparities, thus pushing the vicious cycle through another loop.

The short-term fix is a quota system. But when applied to any supposedly merit-based selection process, quotas are usually counterproductive. Various studies, which accord with our own experience in academia, show that placing talented students from underrepresented groups in math programs that are too advanced for their level of preparedness can lead to discouragement, and often even abandonment of the field. Typically, these students would be better served by slightly less competitive, more nurturing programs that accord with their objectively exhibited levels of performance.

Unfortunately, the trend is pointing in the opposite direction. In fact, at many of our leading academic and research institutions, including the National Academies of Sciences, the American Academy of Arts and Sciences, the National Science Foundation, and the National Institutes of Health, scientific excellence is being supplanted by diversity as the determining factor for eligibility in regard to prizes and other distinctions. And some universities, following the example of the University of California, are now implementing measures to evaluate candidates for faculty positions and promotions based not only on the quality of their research, teaching, and service, but also on their specifically articulated commitment to diversity metrics. Various institutions have even introduced pathways to tenure based on diversity activities alone. The potential damage such measures can bring to academic standards in STEM is immense. And the history of science is full of examples that show how performative adherence to a politically favored ideology, easily faked by opportunistic and mediocre scientists, can lead to the devaluation of entire academic fields.

Needless to say, China pursues none of the equity programs that are sweeping the United States. Quite the contrary: It is building on the kind of accelerated, explicitly merit-based programs, centered on gifted students, that are being repudiated by American educators. Having learned its lesson from the Cultural Revolution, when science and merit-based education were all but obliterated in favor of ideological indoctrination, China is pursuing a far-sighted, long-term strategy to create a world-leading corps of elite STEM experts. In some strategically important fields, such as quantum computing, the country is arguably already ahead of the United States.
