The gender gap is TEM-only

Here’s the percentage of Bachelor’s degrees conferred to women, by major (1970-2012) courtesy of Randal S. Olson.

More than 80 percent of degrees in health and public administration are earned by women, he notes. Nearly 80 percent of education and psychology degrees also go to women. In biology, women earn 58 percent of degrees.

Even in math, statistics and physical sciences, women earn more than 40 percent of degrees. Business is close to 50-50.

He flips the chart to show that men are lagging in everything but engineering, computer science, physical science, math and statistics. Women are close to parity in everything but engineering and computer science.

‘Brain Busters’ win First Lego

A tornado, hurricane or earthquake has devastated a town and wiped out communications. Where can people go for help? Look for the giant balloon.

The Brain Busters — a team of six boys from Sherborne, Massachusetts — has won FIRST LEGO League’s global innovation award for their idea: After a natural disaster, suspend a large sign from a helium balloon that can be seen at long distances.

The Brain Busters’ “love math, computer programming, engineering, and problem solving,” they write. “We built a full scale (100’ high!), working model that we have deployed in high winds, snow storms, and extreme cold.”

State emergency management officials hope to put the idea into use.

More than 500 FIRST LEGO League teams submitted their ideas.

Runners up were the Robotic Raiders of Williamsburg, Iowa, who devised the Cyclone Survivor board game to teach how to prepare for, survive and recover from a tornado, and RobotTec of Santiago, Chile, who designed the Tsunami Evacuation System, which uses retro-reflectors and three-color LED lights on major streets.

‘College premium’ is inflated

The “college premium” has been exaggerated by high-profile studies, write Andrew G. Biggs and Abigail Haddad in The Atlantic. So has the payoff for majoring in a STEM field.

Smarter people are more likely to earn a college degree and to major in engineering, science and math, they write.

Only 58 percent of new college students who began in 2004 had graduated six years later, according to federal data. “Dropout rates are even higher at less selective colleges, whose students are presumably most on the margin between attending college following high school and entering the workforce.”

Calculating returns to education only for those who attend college and graduate is like measuring stock returns for Google while ignoring those for General Motors.

High school students who go on to college are quite different from those go directly to the workforce, they write.

(The collegebound) took a more rigorous high school curriculum, scored better on tests of reading and math, came from higher-income families, were in better physical and mental health, and were less likely to have been arrested. These are all correlated with higher earnings regardless of whether a person attends college . . .

Controlling for “both the risk of not graduating from college and differing personal characteristics” cuts the “earnings boost attributable to college attendance” in half, write Biggs and Haddad.

Graduates in technical fields earn significantly more than graduates in “softer” majors, studies have shown. “High school graduates aiming for high-earning majors such as engineering enter college with higher average SAT scores, according to the National Center for Education Statistics, while those aiming for lower-paying majors have lower average SAT scores,” write Biggs and Haddad. “High-paying jobs also entail longer work hours.”

Students like STEM but don’t succeed

Nearly half of  students say they’re interested in STEM (science, technology, engineering and math) fields — including health care — when they start college, but few will earn a STEM degree, according to a Complete College America report.

Forty-eight percent of recent ACT takers express interest in a STEM major, reports ACT. Forty-one percent of new four-year students and 45 percent of two-year students choose a STEM major, including health sciences, according to National Center for Education Statistics data. Four-year students favor health science, biological science and engineering, while two-year students are interested in health sciences and computer science.

Most don’t make it.

Among 4-year students, 57% of students who choose health sciences and 59% who choose computer science never complete a credential in that field.  The problem is more profound at 2-year colleges where 58% of health science and 72% of computer science students leave the program without a credential.

Those who stick with STEM complete college-level math in their first year, the report finds. Quitters don’t. They also complete few science courses.

Complete College America proposes scheduling college-level math and a majority of STEM courses in the first year to keep students on track. That will help only if students are prepared to pass college math, which many are not.

Nursing is a dream career for many young women from working-class families. Perhaps their brothers dream of being computer techs. It takes a strong foundation in math and science to turn those dreams into reality.

Is the STEM shortage a myth?


On the Big Bang Theory, physicist Sheldon visits neuroscientist Amy in her lab.

The shortage of scientists and engineers is a myth, writes Michael S. Teitelbaum in The Atlantic.  If there were a real shortage, wages would be rising, he writes. To the contrary, “real wages in many—but not all—science and engineering occupations have been flat or slow-growing, and unemployment as high or higher than in many comparably-skilled occupations.”

U.S. students earn mediocre scores on international exams because large numbers of high performers are balanced by lots of low performers, he argues. 

. . . there continues to be a large pool of top science and math students in the U.S. OECD data on “high-performing” students suggests that the U.S. produces about 33 percent of the world total in this category in the sciences, though only about 14 percent in mathematics.

“Every high school graduate should be competent in science and mathematics — essential to success in almost any 21st century occupation and to informed citizenship as well,” he writes. But that doesn’t mean there’s a huge unmet demand for scientists and engineers.  

The STEM shortage myth is a myth, responds Robert D. Atkinson in the Washington Monthly‘s College Guide. Science and engineering graduates are finding jobs — not just in tech-based industries — at higher wages.

As the Brookings Institution’s Jonathan Rothwell shows, the earnings premium for STEM skills (controlling for experience, education and sex) has grown from around 22 percent in 1990 to 30 percent in 2012. Dartmouth’s Matt Slaughter and UC San Diego’s Gordon Hanson found that “the inflation-adjusted wages of major STEM occupations grew over the last decade while real wages for most other U.S. occupations fell.” Hardly evidence of surplus.

STEM shortage denial is rooted in a desire to keep out high-tech immigrants, Atkinson argues.

You can’t go wrong with a computer science major, writes Yahoo’s Rick Newman, looking at PayScale’s 2014 College Report. 

Only two of 288 schools that offer computer science — Indiana University-Purdue and Virginia Commonwealth — produced a return below the median for their graduates. At the top of the scale, meanwhile, more than a dozen computer-science schools returned $1 million or more over 20 years, making this the top-performing field.

By contrast, the return-on-investment for business majors varies depending on the college, he points out. “At nine schools, including Fayetteville State in North Carolina, the University of Montevallo in Alabama and Colorado Mesa University, students studying business actually earned a negative return, according to PayScale. That means they would have done better, on average, if they went to work right out of high school and never spent money on college.”

The earnings data relies on self-reporting, so be wary.

In This is Not Your Father’s STEM Job, Jessica Lahey looks at women who are “forging novel, interdisciplinary, STEM-based careers that blur categories and transcend agenda.”

But are they typical of female STEM workers? Probably not.

LEGO kid builds cheap Braille printer

The Braigo, a low-cost Braille print, was built out of a $350 set of LEGO MINDSTORMS.A California seventh grader has built a low-cost Braille printer out of LEGOs, reports the New York Daily News.

Shubham Banerjee, 12, used a $350 LEGO Mindstorms set, modifying a robot model to make a “Braigo” printer. Basic Braille printers retail for about $2,000 online.

“This is so easy, even my little sister can do it,” Shubham says in a YouTube video.

When his family received an appeal to help the blind, Banerjee decided to get creative. He plans to be an engineer, scientist or surgeon.

Where the money is — and isn’t

NPR charts The Most (And Least) Lucrative College Majors.

Erin Ford graduated from the University of Texas two years ago with a bachelor’s degree in petroleum engineering. Recruiters came to campus to woo her. She got a paid summer internship, which turned into a full-time job after she graduated. Now, at age 24, she makes $110,000 a year.

Michael Gardner just graduated from City College in New York with a degree in psychology. He applied for more than 100 jobs, had trouble getting interviews and worked at Home Depot to make ends meet. “Every single day while I was at work, I’m thinking, ‘I just hope I really don’t get stuck.’ ” Gardner just got a job earning $36,000 a year as a case worker — and he feels lucky to have it.

There are no surprises in the high-earnings chart. On the low side, a health/medical prep degree doesn’t pay well because it requires graduate work.

Why does Mr. Snuffleupagus snuffle?

Sesame Street is trying to teach nature, math, science and engineering ideas to preschoolers, reports the New York Times.

. . . (A cow) made it up the stairs to the beauty parlor but now, her bouffant piled high, she’s stuck. Cows can go up stairs, she moans, but not down.

Enter Super Grover 2.0. Out from his bottomless “utility sock” comes an enormous ramp, which, as the cow cheerily notes before clomping on down, is “a sloping surface that goes from high to low.”

It’s not about the letter C or the number 7  any more. Now Sesame Street is tackling “topics like how a pulley works or how to go about investigating what’s making Mr. Snuffleupagus sneeze,” reports the Times.

Murray Monster, shown here attending Robo Fun School, appears in science-focused segments with children.

Super Grover 2.0 “uses magnets, springs and ‘superpowers’ of investigation, observation and reporting to solve problems through trial and error. Before settling on a ramp for the stuck cow, for instance, he tries a trampoline.”

Last season, Elmo began starring in a daily musical that incorporates math.

On Sept. 24, Sesame Workshop will launch “Little Discoverers: Big Fun With Science, Math and More” on the web site. “In one game, little fingers manipulate a virtual spring to launch pieces of trash into Oscar the Grouch’s trash can, a Sesame Street version of ‘Angry Birds’.”

Higher ed pays — for engineers, nurses

Higher education pays — for technical graduates, concludes a new study. However, “The S in STEM (Science, Technology, Engineering, and Mathematics) is oversold,” the report found. Biology and chemistry majors can expect to earn as little as liberal arts majors.
