Academics--not for everyone

I knew that this perspective would emerge soon. A colleague recently sent me an article that appeared in the Wall Street Journal that basically challenges the "myth" that college, rather scholarly academic work, is suitable for everyone. And the author is correct that "For Most People, College Is a Waste of Time" but it has become so ingrained in American culture that we begin to truly believe that a university education applies to all much like the myth that all people should own a house for which now we are seeing that home ownership is not for everyone simply because it is not affordable in purchasing and maintaining that has been exacerbated by greedy and creative money lenders in an economy where the ratio of a non-incremental wage is disproportional to inflation or price indexes of a bloated commodity's value. I began to see this over 40 years ago when I discovered that the academics and learning value [a "liberal education" if you like] became diluted by a huge influx of students that struggled to stay afloat and understand that a higher education was more than receiving a piece of paper that declared a BA, MA, or Ph.D. A higher degree to many meant better jobs and more money and not the balance of knowledge and scholarship. Many who had those degrees had no knowledge of ancient literature or even construct a decent sentence. Communication skills were poor. Many students then and especially now would be better off attending separate entities of vocational or proprietary educational sources where a skill is pursued. Just look at the television programs from ABC to XYZ Universities offering degrees in paralegal services, nursing, or business administration. Those establishments are interested in providing real skills for the students and make money. The traditional university still maintain academic standards but they too are interested in making money. Some accomplish this through high entrance fees, government and private grants of research [usually scientific with the ultimate goal of technology in mind], and athletics. It is a pity to see students and families become financially in debt from university education expenses when alternatives are available and to realize that not all students are university material.

"For Most People, College Is a Waste of Time"

The Wall Street Journal

Imagine that America had no system of post-secondary education, and you were a member of a task force assigned to create one from scratch. One of your colleagues submits this proposal:

First, we will set up a single goal to represent educational success, which will take four years to achieve no matter what is being taught. We will attach an economic reward to it that seldom has anything to do with what has been learned. We will urge large numbers of people who do not possess adequate ability to try to achieve the goal, wait until they have spent a lot of time and money, and then deny it to them. We will stigmatize everyone who doesn't meet the goal. We will call the goal a "BA."

You would conclude that your colleague was cruel, not to say insane. But that's the system we have in place.

Finding a better way should be easy. The BA acquired its current inflated status by accident. Advanced skills for people with brains really did get more valuable over the course of the 20th century, but the acquisition of those skills got conflated with the existing system of colleges, which had evolved the BA for completely different purposes.

Outside a handful of majors -- engineering and some of the sciences -- a bachelor's degree tells an employer nothing except that the applicant has a certain amount of intellectual ability and perseverance. Even a degree in a vocational major like business administration can mean anything from a solid base of knowledge to four years of barely remembered gut courses.

The solution is not better degrees, but no degrees. Young people entering the job market should have a known, trusted measure of their qualifications they can carry into job interviews. That measure should express what they know, not where they learned it or how long it took them. They need a certification, not a degree.

The model is the CPA exam that qualifies certified public accountants. The same test is used nationwide. It is thorough -- four sections, timed, totaling 14 hours. A passing score indicates authentic competence (the pass rate is below 50%). Actual scores are reported in addition to pass/fail, so that employers can assess where the applicant falls in the distribution of accounting competence. You may have learned accounting at an anonymous online university, but your CPA score gives you a way to show employers you're a stronger applicant than someone from an Ivy League school.

The merits of a CPA-like certification exam apply to any college major for which the BA is now used as a job qualification. To name just some of them: criminal justice, social work, public administration and the many separate majors under the headings of business, computer science and education. Such majors accounted for almost two-thirds of the bachelor's degrees conferred in 2005. For that matter, certification tests can be used for purely academic disciplines. Why not present graduate schools with certifications in microbiology or economics -- and who cares if the applicants passed the exam after studying in the local public library?

Certification tests need not undermine the incentives to get a traditional liberal-arts education. If professional and graduate schools want students who have acquired one, all they need do is require certification scores in the appropriate disciplines. Students facing such requirements are likely to get a much better liberal education than even our most elite schools require now.

Certification tests will not get rid of the problems associated with differences in intellectual ability: People with high intellectual ability will still have an edge. Graduates of prestigious colleges will still, on average, have higher certification scores than people who have taken online courses -- just because prestigious colleges attract intellectually talented applicants.

But that's irrelevant to the larger issue. Under a certification system, four years is not required, residence is not required, expensive tuitions are not required, and a degree is not required. Equal educational opportunity means, among other things, creating a society in which it's what you know that makes the difference. Substituting certifications for degrees would be a big step in that direction.

The incentives are right. Certification tests would provide all employers with valuable, trustworthy information about job applicants. They would benefit young people who cannot or do not want to attend a traditional four-year college. They would be welcomed by the growing post-secondary online educational industry, which cannot offer the halo effect of a BA from a traditional college, but can realistically promise their students good training for a certification test -- as good as they are likely to get at a traditional college, for a lot less money and in a lot less time.

Certification tests would disadvantage just one set of people: Students who have gotten into well-known traditional schools, but who are coasting through their years in college and would score poorly on a certification test. Disadvantaging them is an outcome devoutly to be wished.

No technical barriers stand in the way of evolving toward a system where certification tests would replace the BA. Hundreds of certification tests already exist, for everything from building code inspectors to advanced medical specialties. The problem is a shortage of tests that are nationally accepted, like the CPA exam.

But when so many of the players would benefit, a market opportunity exists. If a high-profile testing company such as the Educational Testing Service were to reach a strategic decision to create definitive certification tests, it could coordinate with major employers, professional groups and nontraditional universities to make its tests the gold standard. A handful of key decisions could produce a tipping effect. Imagine if Microsoft announced it would henceforth require scores on a certain battery of certification tests from all of its programming applicants. Scores on that battery would acquire instant credibility for programming job applicants throughout the industry.

An educational world based on certification tests would be a better place in many ways, but the overarching benefit is that the line between college and noncollege competencies would be blurred. Hardly any jobs would still have the BA as a requirement for a shot at being hired. Opportunities would be wider and fairer, and the stigma of not having a BA would diminish.

Most important in an increasingly class-riven America: The demonstration of competency in business administration or European history would, appropriately, take on similarities to the demonstration of competency in cooking or welding. Our obsession with the BA has created a two-tiered entry to adulthood, anointing some for admission to the club and labeling the rest as second-best.

Here's the reality: Everyone in every occupation starts as an apprentice. Those who are good enough become journeymen. The best become master craftsmen. This is as true of business executives and history professors as of chefs and welders. Getting rid of the BA and replacing it with evidence of competence -- treating post-secondary education as apprenticeships for everyone -- is one way to help us to recognize that common bond.

School Days--2008

Well, it's that time of the season when the youth of America return to the grind of academic studies. I always enjoyed my many years of university life and it wasn't all academics. There were a rash of imported films by Antononi, Bergman, Fellini, Godard, and Kourisawa...promptly followed by lively esoteric discussions at Mike's Tavern or Kelly's Bar in ole KC or a long forgotten pub in the "windy city". Take it from uncles Mercury and Tim that academics are fine and valuable, but have some fun too. Good wishes to all students. And special wishes of success to Bruna de Oliveria and Andie Byrnes...I expect to review those Ph.D. theses soon...physics and Egyptology.

The academics...future scholars

For no particular reason other than to champion an individual for meritorious endeavors in the arena of academics, I will spotlight individuals in the academic realm and wish them unqualified success.

Bruna De Oliveira

Bruna De Oliveira is from Natal, Brazil and currently working on her Ph.D. in "Adaptive Quantum Design" at USC in Los Angeles, California.

"Bruna is working on electron transport through semiconductor heterostructures. Her approach uses a propagation matrix method which she has generalized to include the effects of electron-phonon scattering in these structures."

We are developing tools for designing nano-scale devices in which quantum degrees of freedom play an important role. Quantum systems with made-to-order properties, such as filters, modulators, and switches, are constructed from the atomic level up. The guiding idea of our approach is that in order to achieve such desired system responses, symmetries such as the translational invariance of conventional crystals have to be broken. The core of adaptive quantum design is therefore the search for optimum configurations of the system constituents, such as atomic positions in an artificial synthetic solid, that enable a desired system response, e.g. optical absorption at certain frequencies.

As an illustrative example, let us consider interacting atoms described by a long-ranged tight-binding model,

Here the overlap integral is determined by the distance between the atoms and by the nature of the atomic orbitals. The dependence on inter-atomic spacing can be parameterized as a power-law,

where α = 1.5 - 3.0. By breaking the translational symmetry of this system, desired responses can be emulated, e.g. a flat spectral function, or quasi-2D or quasi-3D response in a 1D array.

The above left figure shows the resulting spatial configuration of atoms in a two-dimensional system with periodic boundary conditions. The chosen target function in this case is a top-hat density of states that is flat within a certain energy regime, and zero otherwise (shown in the right figure). Since this specific target is particle-hole symmetric, i.e. there are as many states above and below zero-energy, the dominant building blocks that are discovered by the numerical search of the best system configuration are dimer molecules. Other target functions that break particle-hole symmetry require more complicated building blocks, such as trimer and quadrumer molecules.

Another example for adaptive quantum design are photonic structures with dielectric rods of variable size and position. Existing devices based on ordered photonic crystals have only limited functionality. On the other hand, adaptive design tools enable new optimized broken-symmetry nano-photonic devices with greater sensitivity, such as mux, combiners, splitters, and channel dropping filters.

Effective numerical search algorithms are essential to find such configurations in the large phase space of possible solutions which includes collective many-body resonances. We have explored and tested several approaches, including guided random walk, simulated annealing, and genetic algorithms. Their convergence properties differ and depend strongly on system parameters. The plot below shows a comparison of these methods which were benchmarked on the same computer. The convergence criterion Δ in this case is the squared difference between a top-hat target density of states and the density of states achieved by adjusting the positions of the constituent atoms. Its is observed that some of the simpler search algorithms tend to get stuck in local minima, whereas the more sophisticated ones find a lower minimum.

Adaptive quantum design is an enabling method for future advances in nano-technology. It relies on realistic physical models and on efficient numerical search algorithms for global minima. It can be applied to microscopic systems in order to enable and enhance their functionality. The challenge is to solve the inverse problem where a target solution is given and the corresponding system configuration has to be found. On the way to matching such target, new building blocks of broken-symmetry configurations can be discovered. This approach enables us to design ultra-small devices and simultaneously to discover novel phenomena that are not found in conventional solids.

Andie Byrnes

Andie Byrnes is from Great Britain and is doing graduate work at UCL, London working towards her Ph. D. whose thesis is "Origins and development of Neolithic farming in the Faiyum and Cairo areas of Egypt."

As she has written:

"I trained as an archaeologist in Scotland many years ago, but lack of funds and lack of sun drove me into telecommunications (wireless, interactive TV and Internet) where I have been working for the last 15 years. However, once archaeology is in your blood, it never goes away, and I am now carrying out post-graduate studies in Egyptian Archaeology (prehistory) at UCL, London."
