What works in education: the lessons according to McKinsey

THE British government, says Sir Michael Barber, once an adviser to the former prime minister, Tony Blair, has changed pretty much every aspect of education policy in England and Wales, often more than once. "The funding of schools, the governance of schools, curriculum standards, assessment and testing, the role of local government, the role of national government, the range and nature of national agencies, schools admissions"—you name it, it's been changed and sometimes changed back. The only thing that hasn't changed has been the outcome. According to the National Foundation for Education Research, there had been (until recently) no measurable improvement in the standards of literacy and numeracy in primary schools for 50 years.

England and Wales are not alone. Australia has almost tripled education spending per student since 1970. No improvement. American spending has almost doubled since 1980 and class sizes are the lowest ever. Again, nothing. No matter what you do, it seems, standards refuse to budge (see chart). To misquote Woody Allen, those who can't do, teach; those who can't teach, run the schools.

Why bother, you might wonder. Nothing seems to matter. Yet something must. There are big variations in educational standards between countries. These have been measured and re-measured by the OECD's Programme for International Student Assessment (PISA) which has established, first, that the best performing countries do much better than the worst and, second, that the same countries head such league tables again and again: Canada, Finland, Japan, Singapore, South Korea.

Those findings raise what ought to be a fruitful question: what do the successful lot have in common? Yet the answer to that has proved surprisingly elusive. Not more money. Singapore spends less per student than most. Nor more study time. Finnish students begin school later, and study fewer hours, than in other rich countries.

Now, an organisation from outside the teaching fold—McKinsey, a consultancy that advises companies and governments—has boldly gone where educationalists have mostly never gone: into policy recommendations based on the PISA findings. Schools, it says*, need to do three things: get the best teachers; get the best out of teachers; and step in when pupils start to lag behind. That may not sound exactly "first-of-its-kind" (which is how Andreas Schleicher, the OECD's head of education research, describes McKinsey's approach): schools surely do all this already? Actually, they don't. If these ideas were really taken seriously, they would change education radically.

Begin with hiring the best. There is no question that, as one South Korean official put it, "the quality of an education system cannot exceed the quality of its teachers." Studies in Tennessee and Dallas have shown that, if you take pupils of average ability and give them to teachers deemed in the top fifth of the profession, they end up in the top 10% of student performers; if you give them to teachers from the bottom fifth, they end up at the bottom. The quality of teachers affects student performance more than anything else.

Yet most school systems do not go all out to get the best. The New Commission on the Skills of the American Workforce, a non-profit organisation, says America typically recruits teachers from the bottom third of college graduates. Washington, DC recently hired as chancellor for its public schools an alumna of an organisation called Teach for America, which seeks out top graduates and hires them to teach for two years. Both her appointment and the organisation caused a storm.

A bias against the brightest happens partly because of lack of money (governments fear they cannot afford them), and partly because other aims get in the way. Almost every rich country has sought to reduce class size lately. Yet all other things being equal, smaller classes mean more teachers for the same pot of money, producing lower salaries and lower professional status. That may explain the paradox that, after primary school, there seems little or no relationship between class size and educational achievement.
AP Asian values or good policy?

McKinsey argues that the best performing education systems nevertheless manage to attract the best. In Finland all new teachers must have a master's degree. South Korea recruits primary-school teachers from the top 5% of graduates, Singapore and Hong Kong from the top 30%.

They do this in a surprising way. You might think that schools should offer as much money as possible, seek to attract a large pool of applicants into teacher training and then pick the best. Not so, says McKinsey. If money were so important, then countries with the highest teacher salaries—Germany, Spain and Switzerland—would presumably be among the best. They aren't. In practice, the top performers pay no more than average salaries.

Nor do they try to encourage a big pool of trainees and select the most successful. Almost the opposite. Singapore screens candidates with a fine mesh before teacher training and accepts only the number for which there are places. Once in, candidates are employed by the education ministry and more or less guaranteed a job. Finland also limits the supply of teacher-training places to demand. In both countries, teaching is a high-status profession (because it is fiercely competitive) and there are generous funds for each trainee teacher (because there are few of them).

South Korea shows how the two systems produce different results. Its primary-school teachers have to pass a four-year undergraduate degree from one of only a dozen universities. Getting in requires top grades; places are rationed to match vacancies. In contrast, secondary-school teachers can get a diploma from any one of 350 colleges, with laxer selection criteria. This has produced an enormous glut of newly qualified secondary-school teachers—11 for each job at last count. As a result, secondary-school teaching is the lower status job in South Korea; everyone wants to be a primary-school teacher. The lesson seems to be that teacher training needs to be hard to get into, not easy.
Teaching the teachers

Having got good people, there is a temptation to shove them into classrooms and let them get on with it. For understandable reasons, teachers rarely get much training in their own classrooms (in contrast, doctors do a lot of training in hospital wards). But successful countries can still do much to overcome the difficulty.

Singapore provides teachers with 100 hours of training a year and appoints senior teachers to oversee professional development in each school. In Japan and Finland, groups of teachers visit each others' classrooms and plan lessons together. In Finland, they get an afternoon off a week for this. In Boston, which has one of America's most improved public-school systems, schedules are arranged so that those who teach the same subject have free classes together for common planning. This helps spread good ideas around. As one educator remarked, "when a brilliant American teacher retires, almost all of the lesson plans and practices that she has developed also retire. When a Japanese teacher retires, she leaves a legacy."

Lastly, the most successful countries are distinctive not just in whom they employ so things go right but in what they do when things go wrong, as they always do. For the past few years, almost all countries have begun to focus more attention on testing, the commonest way to check if standards are falling. McKinsey's research is neutral on the usefulness of this, pointing out that while Boston tests every student every year, Finland has largely dispensed with national examinations. Similarly, schools in New Zealand and England and Wales are tested every three or four years and the results published, whereas top-of-the-class Finland has no formal review and keeps the results of informal audits confidential.

But there is a pattern in what countries do once pupils and schools start to fail. The top performers intervene early and often. Finland has more special-education teachers devoted to laggards than anyone else—as many as one teacher in seven in some schools. In any given year, a third of pupils get one-on-one remedial lessons. Singapore provides extra classes for the bottom 20% of students and teachers are expected to stay behind—often for hours—after school to help students.

None of this is rocket science. Yet it goes against some of the unspoken assumptions of education policy. Scratch a teacher or an administrator (or a parent), and you often hear that it is impossible to get the best teachers without paying big salaries; that teachers in, say, Singapore have high status because of Confucian values; or that Asian pupils are well behaved and attentive for cultural reasons. McKinsey's conclusions seem more optimistic: getting good teachers depends on how you select and train them; teaching can become a career choice for top graduates without paying a fortune; and that, with the right policies, schools and pupils are not doomed to lag behind.

Nobel's de 2007.

Me preguntaron hoy porque le doy importancia a los premios Nobel.
Es el premio que a nivel internacional reconoce los logros de le humanidad en varias áreas como medicina, física, química, economía , literatura....

El comité que vota son los Nobel's y expertos en esa área- solo los de física votan y analizan los logros de los que merecen ese premio!

El Nobel de la paz- que dieron a Al Gore en 2007 - es !00 % político: lo vota el parlamento Noruego....y lastima que no sean un poco mas abiertos a la PAZ real ... Darfur, Congo, Somalia....
pero YO no tengo voto!

Todos los periódicos usan la mitad o mas de su papel para narrar de deportes ...y/ o cine y sus actores.... sus amores ...y sus divorcios
Vale Beckham los US $ millones que se le paga ?
Yo opino que no! Ertl vale mucho mas del $1.5 millones que le da el Nobel!

Pero pocos periódicos narran en lo que trabajo Ertl por décadas...y eso influye mas en NUESTRAS vidas que el gol de Beckham! El que se molestan en leer lo que logro Ertl me dará la razón....
Como en muchas otras cosas, los valores reales no se aprecian........pero si preocupa el gol que metió...el otro!

eBay & Spyke..

The Skype hyper

Oct 4th 2007
From The Economist print edition
Meg Whitman's career at eBay suffers “an impairment write-down”

Reuters

AMONG the many lessons that Margaret (“Meg”) Whitman has picked up during her three decades as a businesswoman, three stand out, she told an audience at Stanford's business school last year. And those three lessons, she implied, explain why she, as boss of eBay, the world's largest online auctioneer, was right to buy an internet-telephone company called Skype for an astonishingly high price in 2005.

The first lesson, which she learned in 1979, was that attention to detail is all important. At the time, she was fresh out of Harvard Business School and just starting her first job at Procter & Gamble. She was charged with figuring out whether the nozzle on shampoo bottles should be half or three-eighths of an inch wide. Despite the tediousness of the task, “I decided I was going to do the very best job that had ever been done at the Procter & Gamble company”, on whose board she now sits. Bring that sort of “execution” to a firm with as much potential as Skype, she suggested, and the sky would be the limit.

The second lesson occurred in 2002. As boss of eBay, she had noticed that a lot of the sellers and buyers on its site were using an online-payment service called PayPal as a sort of virtual wallet, so she decided to buy it. She negotiated for a year, during which the price kept rising. She concluded that in the internet industry one bids early, boldly and pre-emptively high. That is what she did with Skype.

The third lesson was that in such a fast-moving realm “the price of inaction is far greater than the cost of a mistake.” In any case, mistakes can always be corrected. In other words, it did not matter that the “synergies” between a telephone service and an online flea-market seemed few and far between. In her view, eBay was right to buy first and look for the answers to such concerns later.

Collectively, these three lessons have led to disaster. On October 1st eBay conceded, in the language of book-keepers, that the purchase of Skype was just that. It had paid $2.6 billion up front, and agreed to cough up yet more if Skype met certain targets. It did not. This week eBay said that it would take a $1.4 billion charge in relation to the purchase. A portion of the payment is a settlement that absolves eBay of any further obligations to Skype's original owners. But the bigger part, a so-called “impairment write-down”, represents eBay's loss on its ill-fated investment.

Ms Whitman does not even seem to have remembered her own lessons. In terms of the first, eBay's “execution” in integrating Skype with its main business has been poor. Skype's service has deteriorated: it collapsed completely for two days in August. The second lesson—bid early and high—was observed to a fault. As for the third lesson, the mistake has now been admitted, but not fixed.

Ms Whitman should have known better, because Skype became and continues to be a revolutionary technology precisely because it does not extract much revenue from its customers. “We want to make as little money as possible per user,” Niklas Zennstrom, Skype's co-founder, has said. Skype's breakthrough, in his view, was to point the way towards a time when all voice communication would cost the consumer nothing at all. This week Mr Zennstrom stepped down as Skype's boss; he plans to spend more time on his next disruptive technology, called Joost, which brings television to computer screens.

The rest of Silicon Valley has greeted Ms Whitman's misfortunes with Schadenfreude. But the gloating may be short-lived. By buying Skype, the internet phenomenon of 2005, eBay started a bubble. Google, with its purchase of YouTube, the cyber-star of 2006, inflated it further. And Microsoft and Google now appear tempted to add more froth by investing a silly sum in Facebook, the latest big thing. All three—the internet telephone firm, the video site and the social network—make almost no money. EBay's disappointment with Skype is a timely reminder of where this fad might lead.
Down to earth, but with a thud

Until now, Ms Whitman has not faced serious public criticism. The press, The Economist included, has churned out many an unquestioning paean to her. In part, that is thanks to her sensible, down-to-earth demeanour, an endearing contrast to the self-aggrandising swagger of other Silicon Valley bosses. Ms Whitman loves to go fly-fishing with her sons; she also enjoys recounting how embarrassed they were when she was voted onto a list of “worst-dressed billionaires”. People want to love her, one analyst argues, which might explain why eBay's shareholders allowed her to throw a desperate “Hail Mary pass” at Skype, in the words of another.

Shareholders at eBay, at any rate, will surely now start asking what on earth Ms Whitman, a seasoned executive, was thinking. Certainly, she felt pressure from Wall Street to come up with a big idea to maintain the firm's breakneck growth. Its main business, brokering auctions, has been slowing. In the year to June, product listings on its site fell for the first time ever, by 6%. Like Yahoo!, its neighbour in Silicon Valley, eBay may be gored by Google, the ubiquitous search engine. Increasingly, people with goods to sell set up their own websites and find buyers by advertising on Google's search pages. Google has also begun offering online payment and telephone services that compete directly with PayPal and with Skype.

Ms Whitman also mentioned a fourth lesson during her talk at Stanford. Her main job as boss, she said, is to put “the right person in the right job at the right time”. She emphasised the word “time”, since a manager who was right a few years ago may no longer be today. It is a lesson her own bosses, on eBay's board, will doutbless soon be reviewing.
