A liberal arts education is good and central planning is bad

by Grace

To the critics of “frivolous” humanities majors and advocates who want our government to push for more STEM college graduates, Virginian Postrel responds that a liberal arts education is good and central planning is bad.

The critics miss the enormous diversity of both sides of the labor market. They tend to be grim materialists, who equate economic value with functional practicality. In reality, however, a tremendous amount of economic value arises from pleasure and meaning – the stuff of art, literature, psychology and anthropology. These qualities, built into goods and services, increasingly provide the work for all those computer programmers. And there are many categories of jobs, from public relations to interaction design to retailing, where insights and skills from these supposedly frivolous fields can be quite valuable. The critics seem to have never heard of marketing or video games, Starbucks or Nike, or that company in Cupertino,California, the rest of us are always going on about. Technical skills are valuable in part because of the “soft” professions that complement them.

Chemists Struggle Too

The commentators excoriating today’s students for studying the wrong subjects are pursuing certainty where none exists. Like the health fanatics convinced that every case of cancer must be caused by smoking or a bad diet, they want to believe that good people, people like them, will always have good jobs and that today’s unemployed college grads are suffering because they were self-indulgent or stupid. But plenty of organic chemists can testify that the mere fact that you pursued a technical career that was practical two or three decades ago doesn’t mean you have job security today.

The skills that still matter are the habits of mind I honed in the classroom: how to analyze texts carefully, how to craft and evaluate arguments, and how to apply microeconomic reasoning, along with basic literacy in accounting and statistics. My biggest regret isn’t that I didn’t learn Fortran, but that I didn’t study Dante.

The most valuable skill anyone can learn in college is how to learn efficiently — how to figure out what you don’t know and build on what you do know to adapt to new situations and new problems. Liberal-arts advocates like this argument, but it applies to any field. In the three decades since we graduated, my college friend David Bernstein has gone from computing the speed at which signals travel through silicon chips to being an entrepreneur whose work includes specifying, designing and developing a consumer-oriented smart-phone app.

When he was an undergraduate, he wrote in an e-mail, his professors “stressed that they weren’t there to teach us a soon-to-be obsolete skill or two about a specific language or operating system … but rather the foundations of the field, for example: characteristics of languages and operating systems, how one deals with complex projects and works with others, what is actually computable, the analysis of algorithms, and the mathematical and theoretical foundations of the field, to pick just a few among many. That education has held me in good stead and I’ve often pitied the folks who try to compete during a lifetime of constant technological change without it.” Whether you learn how to learn is more a question of how fundamental and rigorous your education is than of what specific subject you study.

The argument that public policy should herd students into Stem fields is as wrong-headed as the notion that industrial policy should drive investment into manufacturing or “green” industries. It’s just the old technocratic central planning impulse in a new guise. It misses the complexity and diversity of occupations in a modern economy, forgets the dispersed knowledge of aptitudes, preferences and job requirements that makes labor markets work, and ignores the profound uncertainty about what skills will be valuable not just next year but decades in the future.

More jobs for STEM graduates who make technology than for those who use it

by Grace

People who make technology are better off than people who use technology.

That’s one conclusion of a Georgetown University report on College Majors, Unemployment and Earnings.

For recent graduates in Math and Computing unemployment is low for specialists who can write software and invent new applications (6%), but still comparatively high (11.2 percent) for those who use software to manipulate, mine and disseminate information.

The lower unemployment figure is for computer science and mathematics majors, and the higher one is for information systems majors.  All STEM majors are not created equal.

This chart is from Wikimedia.

UPDATE:  After reading Bonnie’s comment, I changed the post title from For job security it’s better to make technology than to use it to More jobs for STEM graduates who make technology than for those who use it.  “Job security” was a poor choice of words, given the cyclical nature of this industry.  In fact, the report predicted a recovery for information systems workers as the economy recovers.  The truth is that economic fluctuations affect all our jobs, although some are more cyclical than others.

Again, STEM college majors are too darn hard for kids these days

by Grace


Students are choosing the easy college majors.

… Although the number of college graduates increased about 29% between 2001 and 2009, the number graduating with engineering degrees only increased 19%, according to the most recent statistics from the U.S. Dept. of Education. The number with computer and information-sciences degrees decreased 14%. Since students typically set their majors during their sophomore year, the first class that chose their major in the midst of the recession graduated this year.

This student switched majors when she found an engineering lab project too darn hard.

To avoid getting an “incomplete” for the course, Ms. Zhou withdrew before the lab ended. Since switching majors she has earned almost straight A’s instead of the B’s and C’s she took home in engineering.

The issues:

  • … introductory courses are often difficult and abstract…
  • … high schools didn’t prepare them for the level of rigor in the introductory courses…
  • … Science classes may also require more time … math and science—though not engineering—students study on average about three hours more per week than their non-science-major counterparts.

Overall, only 45% of 2011 U.S. high-school graduates who took the ACT test were prepared for college-level math and only 30% of ACT-tested high-school graduates were ready for college-level science, according to a 2011 report by ACT Inc.

One solution is to make STEM classes easier more accessible.

Educators have tried to tackle the attrition problem with new programs that they say make engineering more accessible. In 2003, Georgia Institute of Technology split its introductory computer-science class into three separate courses. One was geared toward computer science majors, another to engineering majors, and a third to liberal arts, architecture and management majors. The liberal arts course cut down on computer-science theory in favor of practical tasks like using programming to manipulate photographs, says computer science professor Mark Guzdial. Since the switch, about 85% of students pass, he says.

I don’t understand how this information supports the point that STEM-related jobs don’t pay enough:

That may partly be because the jobs don’t pay enough to attract or retain top graduates. Science, technology, engineering and math majors who stay in a related profession had average annual earnings of $78,550 in 2009, but those who decided to go into managerial and professional positions made more than $102,000, according to an analysis of U.S. Census data by the Georgetown University Center on Education and the Workforce.

What is the difference between a science grad who works in a “related profession” vs. one who is in a “professional position”?  In almost any line of work, managers and professionals earn more than other workers.

College students find that STEM majors are too darn hard

by Grace

College STEM students transfer to other majors at twice the attrition rate of all other majors combined.  This is a problem, according to this New York Times article.

 “We’re losing an alarming proportion of our nation’s science talent once the students get to college,” says Mitchell J. Chang, an education professor at U.C.L.A. who has studied the matter.


Some possible reasons

Poor preparation in grades 6 through 12 (and I’d also add K-5)  for the rigors of STEM courses.  Could it be that the extreme focus on “engagement” at the expense of actual learning in our public schools is a factor?

But, it turns out, middle and high school students are having most of the fun, building their erector sets and dropping eggs into water to test the first law of motion. The excitement quickly fades as students brush up against the reality of what David E. Goldberg, an emeritus engineering professor, calls “the math-science death march.” Freshmen in college wade through a blizzard of calculus, physics and chemistry in lecture halls with hundreds of other students. And then many wash out.

Related to poor preparation, students are unwilling to work hard.

Some students still lack math preparation or aren’t willing to work hard enough.

Lack of fun projects in lower level college STEM classes is another issue.

Other deterrents are the tough freshman classes, typically followed by two years of fairly abstract courses leading to a senior research or design project. “It’s dry and hard to get through, so if you can create an oasis in there, it would be a good thing,” says Dr. Goldberg, who retired last year as an engineering professor at the University of Illinois at Urbana-Champaign and is now an education consultant.

And then there’s grade inflation in non-STEM majors.

The latest research also suggests that there could be more subtle problems at work, like the proliferation of grade inflation in the humanities and social sciences, which provides another incentive for students to leave STEM majors. It is no surprise that grades are lower in math and science, where the answers are clear-cut and there are no bonus points for flair. Professors also say they are strict because science and engineering courses build on one another, and a student who fails to absorb the key lessons in one class will flounder in the next.

,,,
While all these factors play a role, I suspect the heart of the  problem is that students are simply poorly prepared for the academic rigors of STEM majors and have failed to develop good study habits while breezing through the American public school system.  I’ve seen this up close.

By contrast, students in China and India focus relentlessly on math and science from an early age.

“We’re in a worldwide competition, and we’ve got to retain as many of our students as we can,” Dean Kirkpatrick says. “But we’re not doing kids a favor if we’re not teaching them good life and study skills.”

This  general theme seems to dominate the more than 1,000 comments accompanying this article.  Here’s one of my favorites.

I have been teaching introductory college physics for fifteen years now. My observation is that for the most part students come to college excited about pursuing a science career, brimming with illusions and/or misconceptions about what that really entails, and as soon as they find out that it is not all about gazing at stars or looking through a microscope, that it is a lot of hard work and (ugh) algebra (the horror !) is involved, they run like the wind. Simple as that.

In my opinion, it is all about how they are brought up in High School. The seem to think that if something is difficult, someone should “make it easy” for them, that anything that they do not like (such as calculus) must surely be disposable and therefore should be simply removed from curriculum and never imposed on them again, that all it takes is the desire to do well. And it is very hard to change them by the time they get to college.

I know, I sound like an old fart.

Speaking as an authentic old fart, I would agree.

Romantic thoughts kill STEM ambition in college women

by Grace

The journal Personality and Social Psychology Bulletin is about to publish a series of research projects … that suggest that when college-age women think about romance, they become less interested in studying STEM fields. College-age men, however, can get interested in romance without any impact on their engagement with math and science.

The research, conducted by Lora Park at the State University of New York at Buffalo, may offer insight into the gender gap in STEM fields.

Another area of research she is pursuing may or may not be helpful to her efforts, Park said. Since the assumptions of many women appear to be that men find female STEM success unattractive, she hopes to find out whether this is in fact the case.

I’ll stay tuned for that.  From personal experience, I know some men find STEM success very attractive.
