In the last decade or
two, many have called for increased education in STEM fields (science, technology, engineering and math). As an engineer, I may hear more of it than others, or
perhaps I am more attentive to it. Math, particularly algebra, trigonometry and geometry, has been seen as a foundation of
STEM education with much support from the tech
industry that has made it central to the Common Core curriculum used in the
majority of states. However, this math requirement has become a stumbling block
for many on the road to high school and college graduation. As when I was in school, students ask, “Am I ever going to
need to use this?” The answer political scientist (and sometimes math professor) Andrew Hacker proposes in The Math Myth is no.
"This country has a
problems. But more math is mathematics is not one of the solutions,” Andrew
Hacker, The Math Myth and Other STEM
Delusions
One of the first myths
that Hacker tackles is this issue of the usefulness of algebra and other higher
math for STEM careers or adult life in general. Most people never need anything
more advanced than arithmetic (addition, subtraction,
multiplication and division), including most scientist, technicians and
engineers. In the 25 years since I graduated from engineering school, I have
never need to solve a differential equation. Easily 80 percent of the math I do
is arithmetic—possibly more. The rest is basic algebra and basic statistics. On
the rare occasion I’ve needed some more esoteric piece of math, I’ve learned or
relearned it on the job.
In spite of this, the
move in the U.S. has been to require four years of high school math
through Algebra II or beyond, plus a college level course in algebra or more
advanced math. This applies even to students who plan to study liberal arts,
humanities and other subjects that make practically no use of math. This
requirement is the number one academic reason people do not complete high
school or college (there are other reasons, of course, but they are not related
to a required class or subject). Even youth form affluent families with
educated parents can find algebra to be an insurmountable hill. Hacker wonders
how much human potential goes undeveloped because educational opportunities are
denied to people who do not need math beyond arithmetic, but must pass an
algebra course to get their diploma or degree.
Why is math, and
especially algebra, a near universal requirement? Hacker points to college math
professors and their influence on lower level curricula. They want prospective
students to be prepared to move to the advanced subjects they study, though
only on percent of undergraduates major in math, and that drops lower in
graduate schools. These same professors almost never teach the entry level (and
especially not remedial) math classes in their own colleges. For colleges
generally, math can be a weed-out course. Even if most students don’t really
need algebra, the requirement is a quick way to knock down the number of
students. (As an engineering student, my fellows and I understood the sequence
of calculus and math-heavy physics classes required of us as freshmen and sophomores was a way of persuading us to study
something else—I almost did.)
Tech companies also call
for a math intensive education and lots of STEM graduates. Hacker points out
that, in spite of the hype, there are actually not that many STEM jobs in the U.S., nor is there a lot of growth in these
fields. A glut of STEM graduates, in addition to the foreign tech labor market
opened up by H1-B visas, keeps wages low in the tech sector. If there was an
actual shortage, employers would respond with increased wages. Computer programmers don’t use much math and
great majority of them don’t earn high salaries. Sadly, the same is
increasingly true in engineering. My advice to someone interested in an
engineering career would be to pursue it if you find the work interesting, but
don’t do it with the expectation that you’ll get a high salary or rise quickly
because of the demand for your technical skills.
I’d like to mention one
more thing that Hacker brings up. Though the math people learn in school often
has no practical utility in their work or daily life, people have a knack for
math and often do complex mathematical things as part of their jobs. Hacker
uses the example of a carpet layer, but I have seen it in machinists,
carpenters and other skilled laborers. The use and shape materials in ways that
require some complex math, but they don’t write out a page full of equations.
They instead apply tools and methods they have learned on the job. I’m a little
fascinated by some of this tool-based, mechanical math, and it seems to be just
as effective and more understandable that school math, especially since very
few of us aspire to study math for its own sake.
