Do parents seek to maximize the social value of their children?

Let’s say a genetic test indicated a 90% chance that a child-to-come would be troubled with obsessions and unhappy and unsuccessful, and a ten percent chance that the child would grow up to be one of America’s leading entrepreneurs.  Or more modestly, in the positive scenario the child would be comparable to a worker or a scientist who creates $5 million in social value a year.  I believe most parents would feel uneasy about this genetic lottery, even though its expected social value is unambiguously high.  Telling the parents that the expected value of the child for society would be high would not distract them very much from the costs of the risk.

As I see it, many upper middle class parents desire their child to be slightly more successful than they are, and in related but not identical fields and ways.  They certainly would be happy if their child turned out to be the next Bill Gates (and more secure in their retirement), but not that much happier from a parental point of view.  Parents qua parents can get only so happy, and if your kid turns out well by your standards you are already pretty close to that maximum.

Notice how children differ from money.  Big dollar prizes induce risk-taking, at least from some entrepreneurs who have a strong desire for more and more money.  But big “parental prizes,” such a siring a true genius, might not induce much risk-taking with the identities or natures of children.

This is one possible institutional failure if there were “market-based” eugenics, namely that parents would be too risk-averse a social point of view.  We would end up with too much sameness, both across children and across the generations, and not enough monomaniacal creators.

Who needs eTexts and portals when you have drones?

From Down Under, one of the few countries to allow commercial drone deliveries:

Australian textbook rental startup Zookal will begin utilizing drones to make its deliveries in Australia next year, with ambitions of bringing the unique, unmanned delivery method to US customers by 2015. The company says this marks the first commercial use of fully automated drones worldwide. It will fulfill deliveries in Sydney using six drones to start, dropping off textbook purchases at an outdoor location of the customer’s choosing. To wipe away any potential privacy or surveillance fears, the drones aren’t equipped with cameras. Instead, built-in anti-collision technology keeps them clear of trees, buildings, birds, and other potential obstacles.

Both the location of the user and the drone’s GPS coordinates are transmitted via a smartphone app, and Zookal claims deliveries can be completed in as little as two to three minutes once a drone takes flight. You can track the drone’s progress from the app (which will only be available on Android at launch) and head outside once it’s getting close. The drone never fully lowers itself to ground level, but rather hovers overhead and lowers its textbook delivery with the tap of a button on your smartphone.

Online Education and the Tivo Revolution

Here’s a TV schedule from 1963. If you wanted to watch Hootenanny you needed to be in front of the television on Saturday night between 7:30 and 8:30 pm. Have something else to do that night? Too bad. No pause or rewind either.

Here’s a college class schedule from 2010  If you want to learn Accounting with Ms. Gettler you need to be in class on Mondays and Wednesdays between 11:25 am and 12:50 pm (bring your lunch). If you need another class that’s scheduled at the same time, too bad. No pause or rewind either.

A TV Guide looks quaint. Tivo has liberated us from the dictates of the networks. Today we can get entertainment on demand. Next up, education on demand.

Getting beneath the Veil of Effective Schools: Evidence from New York City

That is a new paper by Will Dobbie and Roland G. Fryer Jr., here is the abstract:

In this paper, we collect data on the inner-workings of 39 charter schools and correlate these data with school effectiveness. We find that traditionally collected input measures—class size, per-pupil expenditure, teacher certification, and teacher training—are not correlated with school effectiveness. In stark contrast, we show that an index of five policies suggested by qualitative research—frequent teacher feedback, the use of data to guide instruction, high-dosage tutoring, increased instructional time, and high expectations— explains approximately 45 percent of the variation in school effectiveness. The same index provides similar results in a separate sample of charter schools.

The culture that is England

England is the only country in the developed world where the generation approaching retirement is more literate and numerate than the youngest adults, according to the first skills survey by the Organisation for Economic Co-operation and Development.

In a stark assessment of the success and failure of the 720-million-strong adult workforce across the wealthier economies, the economic thinktank warns that in England, adults aged 55 to 65 perform better than 16- to 24-year-olds at foundation levels of literacy and numeracy. The survey did not include people from Scotland or Wales.

The OECD study also finds that a quarter of adults in England have the maths skills of a 10-year-old. About 8.5 million adults, 24.1% of the population, have such basic levels of numeracy that they can manage only one-step tasks in arithmetic, sorting numbers or reading graphs. This is worse than the average in the developed world, where an average of 19% of people were found to have a similarly poor skill base.

When the results within age groups are compared across participating countries, older adults in England score higher in literacy and numeracy than the average among their peers, while younger adults show some of the lowest scores for their age group.

The Adult Skill Gap

From the NYTimes reporting on the OECD Skills Outlook 2013, a study of adult skills.

The study, perhaps the most detailed of its kind, shows that the well-documented pattern of several other countries surging past the United States in students’ test scores and young people’s college graduation rates corresponds to a skills gap, extending far beyond school. In the United States, young adults in particular fare poorly compared with their international competitors of the same ages — not just in math and technology, but also in literacy.

More surprisingly, even middle-aged Americans — who, on paper, are among the best-educated people of their generation anywhere in the world — are barely better than middle of the pack in skills.

Competency-based education comes to Wisconsin (hi future)

From The Chronicle:

Later this year Wisconsin’s extension system will start a competency-based learning program, called the Flexible Option, in which students with professional experience and training in certain skills might be able to test out of whole courses on their way to getting a degree.

Competency-based learning is already famously used by private institutions like Southern New Hampshire University and Western Governors University, but Wisconsin will be one of the first major public universities to take on this new, controversial form of granting degrees. Among the system’s campuses, Milwaukee was first to announce bachelor’s degrees in nursing, diagnostic imaging, and information science and technology, along with a certificate in professional and business communication. UW Colleges, made up of the system’s two-year institutions, is developing liberal-arts-oriented associate degrees. The Flex Option, as it’s often called, may cost the Wisconsin system $35-million over the next few years, with half of that recovered through tuition. The system is starting with a three-month, all-you-can-learn term for $2,250.

If done right, the Flex Option could help a significant number of adults acquire marketable skills and cross the college finish line—an important goal in Wisconsin, which lags behind neighboring states in percentage of adults with college diplomas. There are some 800,000 people in the state who have some college credits but no degree—among them Wisconsin Gov. Scott Walker, who dropped out of Marquette University. He had pushed the university system to set up the Flex Option early last year, when he was considering inviting Western Governors to the state to close a statewide skills gap in high-demand fields like health care, information technology, and advanced manufacturing.

The article seems to suggest that some professors in the Wisconsin system are opposed to this innovation.  Developing…

*David and Goliath*

Quite possibly it is Gladwell’s best book.  His writing is better yet and also more consistently philosophical.  For all the talk of “cherry picking,” the main thesis is that many qualities which usually appear positive are in fact non-monotonic in value and can sometimes turn negative.  If you consider Gladwell’s specific citations of non-monotonicities to be cherry-picking, you’re not understanding the hypothesis being tested.  Take the book’s central message to be “here’s how to think more deeply about what you are seeing.”  To be sure, this is not a book for econometricians, but it so unambiguously improves the quality of the usual public debates, in addition to entertaining and inspiring and informing us, I am very happy to recommend it to anyone who might be tempted.  It also shows Gladwell’s side as a regional thinker like never before.  And the moral lesson of the work — don’t write people off — is very important indeed and we are far from having fully absorbed it.  The same can be said for the second moral lesson of the book which is don’t overrate your power.

Accrediting individual courses (hi future)

A growing clamor is calling for an accreditor to oversee the quality of college-level learning that occurs outside of college.

The challenge could be taken on by an existing accrediting agency — or a new one — that develops a specialty in non-institutional providers like StraighterLine and Udacity. Or, with more of a trailblazing approach, an accreditor could approve individual courses rather than degrees.

If either idea becomes a reality it would add a seal of approval for a constellation of online course providers and, perhaps, open the door for them to federal financial aid.

Here is further information.  On the down side, note that the fixed cost of monitoring and enforcing ongoing standards on a stand-alone individual course may be fairly high, at least relative to the value of that course.

Can we sell a good undergraduate degree for $10,000?

Dylan Matthews has an interesting discussion of a plan by Anya Kamenetz, you can read an outline of the plan here.  The upshot of her approach is that an entire degree can be done for 10k per student.  There is much in the plan I have sympathy for, and I do think higher education could be much cheaper and still serve most of its useful functions.  That said, I consider this specific proposal to involve some overselling.

Let me just pick up on the single sub-proposal closest to my life:

She [Kamenetz] would also abolish the major of “business,” the single most popular undergraduate major, but perhaps also the least rigorous, and which produces relatively poor-achieving students. Instead, she’d fold practical business classes into the economics major.

Let’s just, for the sake of argument, accept the premise of the business major being less rigorous at many schools.  I would not make such an incendiary claim myself, certainly not about my own school, but this is an exercise in logic, not empirics.

OK, so at many schools below the top, what would happen?  It would be simple: many of the former or would-have-been business majors would not be able to pass the mid- or upper-level classes of the economics major.  What then?

You can flunk out the less scholastically oriented business majors, which is probably not a good idea.

Or you could make all of those economics classes much easier, which is also probably not a good idea.  The better students lose out and the whole major becomes worth less money and also less prestigious for the school.  In essence you end up abolishing the economics major.

Or you can push the former business majors into some other easy major (communications? education?…those are againt purely hypothetical examples, please put aside the empirics).  That’s not the end of the world, but then the point of the exercise is less than clear.  If a lot of students want to be business majors, is it such a big educational gain to shovel them into some major they perhaps do not want and may also be less marketable?

The most likely outcome would be the creation of a multi-tiered economics major, with a harder track and easier track, labeled accordingly, a bit like the B.S. vs. the B.A., though different in the details.  Again, that is hardly the end of the world, and maybe the idea is worth considering, but at this point we must again ask where are the gains.  I have an idea: let’s call the less rigorous economics track the business major.  Or in the interests of the fig leaf producers, how about the business economics major?  The reality is that many schools do combine economics and business and they don’t seem to achieve major competitive or cost advantages in doing so; in fact they may be more likely to encounter clashes of mission and disagreements over what kind of faculty to hire.

(Are there big gains in overhead reduction from consolidating these two departments?  I don’t see it.  And note that some business schools which contain economics departments are broken down into “groups,” sometimes with semi-autonomous status to limit conflict and transactions costs, and that is going to bring back some overhead costs.)

And so on.  Many parts of such proposals cannot be readily translated into reality, at least not a reality where the cost of a four-year degree sinks to 10k total.  A big problem with a lot of “good ideas” for education is simply that (in various hypothetical universes) the students are not up to them.

The high price of land in Singapore, educational Morlocks edition

At N.T.U., a group of researchers has spent the past year gathering available data on the university’s surface topography and subsurface geology.

The preliminary survey, completed late last month, found that the campus, which is in western Singapore, offers opportunities for underground space development. Extensive investigations indicated that rock strata 20 to 30 meters, or 66 to 98 feet, below the surface, are suited for cavern construction with spans as wide as 20 meters wide.

“In the long term, the university may need to go underground” to accommodate projected increases in the student population, said Zhao Zhiye, one of four researchers who worked on the study.

…Designed for both learning and socializing, the learning complex — a group of interconnected caverns — would include the university’s main library, a museum, study rooms, cafeterias and conference halls. The sports hall, beneath the existing university sports complex, would house basketball, badminton and table tennis courts, swimming pools and spectator stands.

The site is here, and it presents recent macro discussions on an issue-by-issue basis in easy to use, easy to scan form.  Furthermore it covers links which I otherwise would not see.  I not only visit the site every day (or more), I use it every day, and there are no more than half a dozen aggregator sites where I would say that.

Markets in everything

University of Toronto students desperate for scarce seats in fully booked classrooms are offering cash to classmates willing to give up a spot, turning registration into a bidding war.

“$100 to whomever drops (History of Modern Espionage),” posted Christopher Grossi on Facebook Tuesday. “I really need this course.”

The third-year history student said the 180-person course filled up before his designated registration time. After talking to the professor without success, he said offering money was his last chance to coax someone to trade with him.

Here is more information, and supposedly, after some point in the process, a near-simultaneous drop and add will in fact allow the trade to take place.
