Andrew Hacker: Is Algebra Necessary? (PUUUUUUUUKE)

About the author: Andrew Hacker is an emeritus professor of political science at Queens College, City University of New York, and a co-author of “Higher Education? How Colleges Are Wasting Our Money and Failing Our Kids — and What We Can Do About It.”

How did this stupid load of crap make it to the New York Times Sunday opinion page anyway? So let's just surrender math to the Chinese, Indians, and Norwegians while we Americans just have empty good feelings, this article is, essentially.

A TYPICAL American school day finds some six million high school students and two million college freshmen struggling with algebra. In both high school and college, all too many students are expected to fail. Why do we subject American students to this ordeal? I’ve found myself moving toward the strong view that we shouldn’t.

My question extends beyond algebra and applies more broadly to the usual mathematics sequence, from geometry through calculus. State regents and legislators — and much of the public — take it as self-evident that every young person should be made to master polynomial functions and parametric equations.

There are many defenses of algebra and the virtue of learning it. Most of them sound reasonable on first hearing; many of them I once accepted. But the more I examine them, the clearer it seems that they are largely or wholly wrong — unsupported by research or evidence, or based on wishful logic. (I’m not talking about quantitative skills, critical for informed citizenship and personal finance, but a very different ballgame.)

This debate matters. Making mathematics mandatory prevents us from discovering and developing young talent. In the interest of maintaining rigor, we’re actually depleting our pool of brainpower. I say this as a writer and social scientist whose work relies heavily on the use of numbers. My aim is not to spare students from a difficult subject, but to call attention to the real problems we are causing by misdirecting precious resources.

The toll mathematics takes begins early. To our nation’s shame, one in four ninth graders fail to finish high school. In South Carolina, 34 percent fell away in 2008-9, according to national data released last year; for Nevada, it was 45 percent. Most of the educators I’ve talked with cite algebra as the major academic reason.

And I found Hacker's take on my state's university entry requirements particularly offensive:

California’s two university systems, for instance, consider applications only from students who have taken three years of mathematics and in that way exclude many applicants who might excel in fields like art or history. Community college students face an equally prohibitive mathematics wall. A study of two-year schools found that fewer than a quarter of their entrants passed the algebra classes they were required to take.

“There are students taking these courses three, four, five times,” says Barbara Bonham of Appalachian State University. While some ultimately pass, she adds, “many drop out.”

The stupid keeps on hurting:

What of the claim that mathematics sharpens our minds and makes us more intellectually adept as individuals and a citizen body? It’s true that mathematics requires mental exertion. But there’s no evidence that being able to prove (x² + y²)² = (x² - y²)² + (2xy)² leads to more credible political opinions or social analysis.

Among the "NYT Picks" comments: one said: "Not one of my students ever told me that they were interested in doing anything with their lives that would involve algebra. But many dropped out because of algebra." (with 37 recommendations)

Another, with 92 recommendations: "Understanding algebra, geometry, and trigonometry shapes perception of the physical world and allows the young minds to grasp the other sciences more firmly. Beyond that, the processes needed to learn math teach young people mental discipline and shape their brain's pathways for higher learning."

(ETA) PZ Myers, a biology professor and atheist advocate, takes down Hacker:

We live in a technological society. Not learning algebra in the public school system means those kids will not be prepared, will not be qualified, to do anything in science and engineering. I’m serious: if you don’t know algebra, you can’t do basic quantitative chemistry, and if you can’t do that, you can’t do biology. At all. Not the molecular/biochemical/bench side, not the ecological/evolutionary/field side. You can’t do physics, that’s for sure. Forget math and statistics. If you’re not capable of grasping statistics, forget psychology, too.

You can probably still be a competent English major, I admit. But wouldn’t we be better off if all the English majors had an inkling of the foundations of science, as well as all the science majors having a touch of the humanities and social sciences? Shouldn’t we expect that even those people who choose not to pursue a college degree ought to have a bare minimum of competence in math and history and language and science and art, if we’re actually going to deem them educated?
