Value of Higher Education Is in the Signaling, Not the Learning

(p. A13) Mr. Caplan, an economist at George Mason University, argues that most of the value of education–especially higher education–comes from “signaling,” not from the content of learning. As a result, Americans are “overeducated,” and it’s time to stop spending so much money (both private and public) on schools.
. . .
After surveying the research on the “transfer of learning,” Mr. Caplan concludes: “Students learn only the material you specifically teach them . . . if you’re lucky.” Generally, they don’t know how to transfer their reasoning from one topic to a related one. As to informal reasoning–the ability to come up with arguments for or against a particular proposition–education’s effect, he says, has been “tiny.” He similarly dispenses with the claim that schools teach common values or civic education. As college attendance has skyrocketed, he notes, voter turnout has declined.

Cognitive Abilities Highest After Waking in Morning

(p. A15) A raft of studies in disciplines ranging from medicine to economics have yielded all sorts of data on the science of timing. Daniel Pink, an author who regularly applies behavioral science to the realm of work, has handily distilled the findings in “When: The Scientific Secrets of Perfect Timing.”
. . .
For a slim book, “When” brims with a surprising amount of insight and practical advice. In amiable, TED-talk-ready prose, Mr. Pink offers scheduling tips for everything from workouts to weddings. Exercise, for example, is best done in the morning for those who hope to lose weight, build strength and boost their mood through the day.
. . .
Moods are not the only things that shift every 24 hours. Our cognitive abilities also morph in foreseeable ways. We are often sharpest in the hours after waking up, which makes morning the best time to take exams or answer logic problems. Researchers analyzing four years of test results for two million Danish schoolchildren found that students consistently scored higher in mornings than afternoons.

Kid Paid $100,000 to Skip College and Mine Asteroids

(p. 18) As I sat down for lunch at a restaurant in Los Angeles, I placed a copy of “Valley of the Gods,” by Alexandra Wolfe, on the table, and a waitress walking by stopped to peer at the cover. . . .
“It’s about Silicon Valley,” I began. “It follows this young kid, John Burnham, who gets paid $100,000 by this weird billionaire guy, Peter Thiel, whom you’ve probably heard of; he’s a big Trump supporter and spoke at the Republican National Convention?” — a blank stare from the waitress. “Anyway, Thiel pays him (and a bunch of other kids) to forgo college so Burnham can mine asteroids, but he doesn’t actually end up mining the asteroids and. . . .”
. . .
The book begins with the protagonist, Burnham (or antagonist, depending whose side you’re on), who isn’t old enough to drink yet but is debating dropping out of college to follow the Pied Piper of libertarian and contrarian thinking, Peter Thiel, to Silicon Valley. As Wolfe chronicles, Thiel, who has a degree from Stanford University and largely credits where he is today (a billionaire) to his time at that school, started the Thiel Fellowship, in 2011, which awards $100,000 to 20 people under 20 years old to say no to M.I.T., Stanford or, in Burnham’s case, the University of Massachusetts, to pursue an Ayn Randian dream of disrupting archetypal norms.
It won’t be giving away the ending by pointing out that it doesn’t end well for Burnham.

For Jane Jacobs, “Self-Certainty” Was Better than a Doctorate

(p. 17) Like the critic Pauline Kael and the conservative activist Phyllis Schlafly, Jane Jacobs arrived to churn the fertile soil of American cultural ideology in the 1960s, brandishing a disciplined populist intellect and a comfort with courting enmity. All three were middle-aged mothers by the time they would shake things up. That Jacobs, nee Butzner in 1916, would force a reconsideration of the nature and purpose of cities was an outcome her young adulthood would have hardly suggested. An unexceptional student at Central High in Scranton, Pa., she later studied at Columbia before failing to gain formal admission to Barnard and abandoning the pursuit of a degree entirely. These experiences, Robert Kanigel maintains in his biography “Eyes on the Street: The Life of Jane Jacobs,” left her with a distaste for the academy that she carried throughout her career.
Where others had doctorates, Jacobs had a self-certainty that was manifest early on. In a chronicling of her childhood so thorough it includes the number of times she was late for homeroom during her first semester of high school (seven), Kanigel recounts an incident in which Jane was expelled from third grade for urging her classmates to dismiss the entreaties of a hygiene instructor, who asked them to pledge to brush their teeth twice a day for the rest of their lives. In Jane’s view, the promise would be impossible to keep, making the request absurd.

Yale President Defends Free Speech

(p. A23) In 1963, the Yale Political Union, one of the oldest collegiate debate societies in the United States, invited the defiant segregationist governor of Alabama, George Wallace, to Yale. Just a few weeks before his scheduled visit, Klansmen bombed the 16th Street Baptist Church in Birmingham, Ala., killing four African-American schoolgirls and wounding 22 others.
Wallace — the personification of Southern hostility to integration — had famously stood on the portico of the Alabama State Capitol and declared in his inaugural speech, “Segregation now, segregation tomorrow, segregation forever!” Many blamed Wallace for inciting the violence.
The provost and acting president of Yale, Kingman Brewster Jr., advised the students to withdraw their invitation. Mayor Richard C. Lee said Wallace was “officially unwelcome” in New Haven.
Not everyone agreed. Pauli Murray, a lawyer and civil rights activist pursuing her doctorate of jurisprudence at the law school, wrote to Brewster, urging him to send a clear message that Wallace should be allowed to express his views at Yale.
. . .
In linking the fate of the civil rights movement to Wallace’s speech, she reminds us that the Constitution makes for strange bedfellows. It applies to segregationists and integrationists, civil rights activists and self-proclaimed racists. All Americans can lay claim to its protections, but those, like Murray, who seek to change society and extend freedoms to the most marginalized may need it most.

Union Blocks Firing of Teachers Who Do Not Teach

(p. A1) Francis Blake has not held a permanent position in a New York City public school in at least five years. At his last job, in a Bronx elementary school, records show he was disciplined for incompetence, insubordination and neglect of duties — he had been caught sleeping in a classroom when he was supposed to be helping with dismissal.
Felicia Alterescu, a special-education teacher, has been without a permanent post since 2010, despite high demand for special education teachers. According to records, in addition to getting a string of unsatisfactory ratings, she was disciplined for calling in sick when she actually went to a family reunion. She also did not tell the Education Department that she had been arrested on harassment charges.
This month, Mr. Blake, Ms. Alterescu and hundreds of other teachers who are part of a pool known as the Absent Teacher Reserve could be permanently back in classrooms, as the city’s Education Department places them in jobs at city schools.
The reserve is essentially a parking lot for staff members who have lost their positions, some because of school closings and budget cuts, others because of disciplinary problems, but cannot be fired. It grew significantly as a result of a 2005 deal between the Bloomberg administration, which wanted to give principals control over hiring, and the teachers’ un-(p. A17)ion. Since then, the union has fiercely protected the jobs of teachers in the reserve, resisting attempts to put a time limit on how long a teacher can remain there.

High Demand for STEM Workers Is Mainly High for Workers in Info Tech

(p. 10) A working grasp of the principles of science and math should be essential knowledge for all Americans, said Michael S. Teitelbaum, an expert on science education and policy. But he believes that STEM advocates, often executives and lobbyists for technology companies, do a disservice when they raise the alarm that America is facing a worrying shortfall of STEM workers, based on shortages in a relative handful of fast-growing fields like data analytics, artificial intelligence, cloud computing and computer security.
“When it gets generalized to all of STEM, it’s misleading,” said Mr. Teitelbaum, a senior research associate in the Labor and Worklife Program at Harvard Law School. “We’re misleading a lot of young people.”
Unemployment rates for STEM majors may be low, but not all of those with undergraduate degrees end up in their field of study — only 13 percent in life sciences and 17 percent in physical sciences, according to a 2013 National Science Foundation survey. Computer science is the only STEM field where more than half of graduates are employed in their field.

University of Chicago Seeks Discourse, Not Deference

(p. A21) Several years ago Robert Zimmer was asked by an audience in China why the University of Chicago was associated with so many winners of the Nobel Prize — 90 in all, counting this month’s win by the behavioral economist Richard Thaler. Zimmer, the university’s president since 2006, answered that the key was a campus culture committed to “discourse, argument and lack of deference.”
. . .
The University of Chicago has always been usefully out of step with its peers in higher education — it dropped out of the Big Ten Conference and takes perverse pride in its reputation as the place where fun goes to die. It was out of step again last year when Jay Ellison, the dean of students, sent a letter to incoming freshmen to let them know where the college stood in respect to the campus culture wars.
“Our commitment to academic freedom,” he wrote, “means that we do not support so-called ‘trigger warnings,’ we do not cancel invited speakers because their topics might prove controversial, and we do not condone the creation of intellectual ‘safe spaces’ where individuals can retreat from ideas and perspectives at odds with their own.”
The letter attracted national attention, with cheering from the right and caviling on the left. But its intellectual foundation had been laid earlier, with a 2015 report from a faculty committee, convened by Zimmer, on free expression. Central to the committee’s findings: the aim of education is to make people think, not spare them from discomfort.

Federal and State Mandates Constrain “Creativity in the Classroom”

(p. A11) Mrs. DeVos sees choice as a means to the end of promoting educational innovation–including within traditional public schools. “Instead of focusing on systems and buildings, we should be focused on individual students,” she says. That means encouraging young people “to pursue their curiosity and their interests, and being OK with wherever that takes them–not trying to conform them into a path that everybody has to take.”
What stands in the way? “I think a real robust defense of the status quo is the biggest impediment,” Mrs. DeVos says. She doesn’t mention teachers unions until I raise the subject, whereupon she observes: “I think that they have done a good job in continuing to advocate for their members, but I think it’s a focus more around the needs of adults” rather than students.
Many of the adults are frustrated, too. Recently I met a veteran middle-school teacher who said his creativity in the classroom has been increasingly constrained by federal and state mandates on curriculum and testing. Another teacher I know, who wants to start a charter, complains that “it is getting harder and harder to work for the idiots in traditional schools.”
That sounds familiar to Mrs. DeVos. “I do hear sentiments from many teachers like that,” she says, “and particularly from many teachers that are really effective and creative themselves. I’ve also heard from many teachers who have stopped teaching because they feel like they can’t really be free to do their best, because they’re either subtly or not subtly criticized by peers who might not be as effective as they are–or by administrators who don’t want to see them sort of excelling and upsetting the apple cart within whatever system they’re in.”
She continues: “I talked to a bunch of teachers that had left teaching that had been Teachers of the Year in their states or their counties or whatever. I recall one of the teachers said he just felt so beaten down after being told repeatedly to have his class keep it down–that they were having too much fun, and the kids were too engaged. Well, what kind of a message is that?”

Nursing Unions “Keep Aides from Encroaching on Their Turf”

(p. B2) There are a few reasons long-term care is such a bad job. “Most people see it as glorified babysitting,” said Robert Espinoza, vice president for policy at PHI, an advocacy group for personal care workers that also develops advanced training curriculums to improve the quality of the work force.
The fact that most workers are immigrant women does not help the occupation’s status. Occupational rules that reserve even simple tasks for nurses, like delivering an insulin shot or even putting drops into a patient’s eye, also act as a barrier against providing care workers with better training.
. . .
. . . there are the powerful nursing unions, ready to fight tooth and nail to keep aides from encroaching on their turf. Carol Raphael, former chief executive of the Visiting Nurse Service of New York, the largest home health agency in the United States, told Professor Osterman that when the association tried to expand the role of home-care aides, the “nurses went bonkers.”

Soviets Expelled Math Innovator from High School, When He Denied That Dostoyevsky Was Pro-Communist

(p. A12) Vladimir Voevodsky, formerly a gifted but restless student who flunked out of college out of boredom before emerging as one of the most brilliant and revolutionary mathematicians of his generation, died on Sept. 30 [2017] at his home in Princeton, N.J. He was 51.
. . .
Vladimir was kicked out of high school three times, once for disagreeing with his teacher’s assertion that Dostoyevsky, who died in 1881, was pro-Communist. He was also kicked out of Moscow University after failing academically, having stopped attending classes that he considered a waste of time.
. . .
How do mathematicians know that something they prove is actually true?
This question became urgent for him as mathematicians were discovering — sometimes decades after publication — that proof after proof, including one of his own, had critical flaws.
Mathematical arguments had gotten so complicated, he realized, that other mathematicians rarely checked them in detail. And his stellar reputation only made the problem worse: Everyone assumed that his proofs must be right.
Dr. Voevodsky realized that human brains could not keep up with the ever-increasing complexity of mathematics. Computers were the only solution. So he embarked on an enormous project to create proof-checking software so powerful and convenient that mathematicians could someday use it as part of their ordinary work and create a library of rock-solid mathematical knowledge that anyone in the world could access.
Computer scientists had worked on the problem for decades, but it was territory only a few mathematicians had ever ventured into. “Among mathematicians, computer proof verification was almost a forbidden subject,” Dr. Voevodsky wrote.
The problem was that these systems were extraordinarily cumbersome. Checking a single theorem could require a decade of work, because the computer essentially had to be taught all of the mathematics a proof was built on, in agonizing, inhuman detail. Ordinary mathematicians intent on expanding the borders of the field could not possibly devote that kind of effort to checking their proofs.
Somehow, computers and humans needed to be taught to think alike.
Dr. Voevodsky developed a stunningly bold plan for how to do so: He reformulated mathematics from its very foundation, giving it a new “constitution,” as Dr. Hales put it. Mathematics so reformulated would be far friendlier to computers and allow mathematicians to talk to computers in a language that was much closer to how mathematicians ordinarily think.
Today, Dr. Voevodsky declared in 2014, “computer verification of proofs, and of mathematical reasoning in general, looks completely practical.”
