German vs. American schools


Why I Dread Returning to an American Public School
By Firoozeh Dumas, NY Times
After almost six years in Munich, my family and I will soon be returning to California, and there are a few things I already know I will miss. I am not talking about the obvious (fresh pretzels, fresh pretzels with cheese, fresh pretzels with cheese and pumpkin seeds, no potholes, universal health care) but the less known differences that come with spending time in schools.
We are fortunate to live in a part of Munich with top-notch public schools, similar to where we lived in America. We pay a few percentage points more in taxes than we paid in California, but holy Betsy DeVos, do we get more!
Our daughter’s elementary school, which she graduated from a few years ago, offered a rich curriculum, from math and sciences to arts and languages. After school, in addition to the more traditional offerings of chess, theater and computers, she could take circus lessons, where children learned to juggle, walk on a tightrope and ride a unicycle. Since her school did not have a pool, students were bused every week to a nearby sports club for swim lessons, at no extra charge.

Productive Failure, the secret of learning math

FIT FOR FAILURE
The best way to learn math is to learn how to fail productively
Quarz, 10/29/2015
Singapore, the land of many math geniuses, may have discovered the secret to learning mathematics (pdf). It employs a teaching method called productive failure (pdf), pioneered by Manu Kapur, head of the Learning Sciences Lab at the National Institute of Education of Singapore.

Encouraging the Next Generation

 By Susan Cramm, strategy + business

About a month ago, I was sitting on the patio of a local coffee shop with a wonderful 14-year-old young lady who we’ll call Alyssa. Full of love and life, she easily connects with others, is compassionate with children, and is starting to demonstrate an artistic bent. But when we met, she was feeling a bit depressed. I asked her to consider her gifts and strengths, to help her refocus on the positive. But instead, she grew quiet and looked at me blank faced, seemingly dumbstruck and unable to see what is easily apparent to others.

How Robert Redford’s family are changing our thinking on dyslexia

Elizabeth Day, The Observer
On the face of it, Dylan Redford has everything going for him—he is a handsome, intelligent and artistic 22-year-old who happens to be the grandson of Robert Redford. But he is also severely dyslexic and, at the age of 10, could barely read or write.

A new successful way of teaching: Flipped classrooms

Turning Education Upside Down
By Tina Rosenberg, NY Times
Three years ago, Clintondale High School, just north of Detroit, became a “flipped school”—one where students watch teachers’ lectures at home and do what we’d otherwise call “homework” in class. Teachers record video lessons, which students watch on their smartphones, home computers or at lunch in the school’s tech lab. In class, they do projects, exercises or lab experiments in small groups while the teacher circulates.

The Granny Cloud

Have you heard about a social innovation initiative called, ‘The Granny Cloud’? It is where U.K.-based grandmothers volunteer to help teach children in India. This project is the brainchild of Prof Sugata Mitra, who is known for his hole-in-the-wall computer scheme which put basic PCs into some of the poorest parts of India. Prof Mitra installed the first computer on the wall of his Delhi office, opposite a slum, and was amazed to see that the children, initially curious about the machine, soon became self-taught experts. Within days they were able to browse the Internet, cut and paste copy, drag and drop items and create folders.

The Best Career Advice You Won’t Want To Hear

By Creel Price, LinkedIn
As a fresh-faced university graduate I was eager to find a shortcut to fast track my way up the corporate ladder. Though being from a rural background, the only person around who had achieved distinction in a major organisation was my imposing great uncle Gus—a second world-war veteran who reached an executive level at one of Australia’s largest industrial companies.

How Italy’s Famed Educator Shaped Silicon Valley

Montessori In Mountain View
By Marco Bardazzi, La Stampa
The life stories of great people who have changed America can often be traced back to a common starting point: a boat from Europe sailing into the New York harbor with a salute toward the Statue of Liberty and an obligatory passage with the immigration officials at Ellis Island.

Don’t work. Be hated. Love someone.




Written by Adrian Tan, author of The Teenage Textbook. This was his speech to a graduating class of 2008.

You’ve probably been told the big lie that “Learning is a lifelong process” and that therefore you will continue studying and taking masters’ degrees and doctorates and professorships and so on. You know the sort of people who tell you that? Teachers. Don’t you think there is some measure of conflict of interest? They are in the business of learning, after all. Where would they be without you? They need you to be repeat customers.

The good news is that they’re wrong.

Bedtime Math: A Problem a Day Keeps Fear of Arithmetic Away



By Bonnie Rochman, TIME

For many parents with young children, the bedtime routine is a firmly entrenched system involving a warm bath, a good book, a kiss and a hug. Toying with that equation borders on sacrilege, but Laura Overdeck thinks it’s time to make room for a math problem alongside the nightly story.

Luck, scientifically explained



What’s Luck Got to Do With It?

By Jim Collins and Morten T. Hansen, NY Times
Recently, we completed a nine-year research study of some of the most extreme business successes of modern times. We examined entrepreneurs who built small enterprises into companies that outperformed their industries by a factor of 10 in highly turbulent environments. We call them 10Xers, for “10 times success.”
The very nature of this study—how some people thrive in uncertainty, lead in chaos, deal with a world full of big, disruptive forces that we cannot predict or control—led us to smack into the question, “Just what is the role of luck?”
Could it be that leaders’ skills account for the difference between just meeting their industry’s average performance (1X success) and doubling it (2X)? But that luck accounts for all the difference between 2X and 10X?
Maybe, or maybe not.
But how on Earth could we go about quantifying something as elusive as “luck”? The breakthrough came in seeing luck as an event, not as some indefinable aura. We defined a “luck event” as one that meets three tests. First, some significant aspect of the event occurs largely or entirely independent of the actions of the enterprise’s main actors. Second, the event has a potentially significant consequence—good or bad. And, third, it has some element of unpredictability.
We systematically found 230 significant luck events across the history of our study’s subjects. We considered good luck, bad luck, the timing of luck and the size of “luck spikes.” Adding up the evidence, we found that the 10X cases weren’t generally “luckier” than the comparison cases. (We compared the 10X companies with a control group of companies that failed to become great in the same extreme environments.)
The 10X cases and the control group both had luck, good and bad, in comparable amounts, so the evidence leads us to conclude that luck doesn’t cause 10X success. The crucial question is not, “Are you lucky?” but “Do you get a high return on luck?”
Return on luck: We call it ROL.
SO why did Bill Gates become a 10Xer, building a great software company in the personal computer revolution? Through one lens, you might see Mr. Gates as incredibly lucky. He just happened to have been born into an upper-middle-class American family that had the resources to send him to a private school. His family happened to enroll him at Lakeside School in Seattle, which had a Teletype connection to a computer upon which he could learn to program—something that was unusual for schools in the late 1960s and early ’70s.
He also just happened to have been born at the right time, coming of age as the advancement of microelectronics made the PC inevitable. Had he been born 10 years later, or even just five years later, he would have missed the moment.
Mr. Gates’s friend Paul Allen just happened to see a cover article in the January 1975 issue of Popular Electronics, titled “World’s First Microcomputer Kit to Rival Commercial Models.” It was about the Altair, designed by a small company in Albuquerque. Mr. Gates and Mr. Allen had the idea to convert the programming language Basic into a product that could be used on the Altair, which would put them in position to be the first to sell such a product for a personal computer. Mr. Gates went to college at Harvard, which just happened to have a PDP-10 computer upon which he could develop and test his ideas.
Wow, Bill Gates was really lucky, right?
Yes, he was. But luck is not why Bill Gates became a 10Xer. Consider these questions:
• Was Bill Gates the only person of his era who grew up in an upper middle-class American family?
• Was he the only person born in the mid-1950s who attended a secondary school with access to computing?
• Was he the only person who went to a college with computer resources in the mid-’70s? The only one who read the Popular Electronics article? The only one who knew how to program in Basic?
No, no, no, no and no.
Lakeside may have been one of the first schools to have a computer that students could use during those years, but it wasn’t the only such school.
Mr. Gates may have been a math and computer whiz kid at a top college that had computers in 1975, but he wasn’t the only math and computer whiz kid at Harvard, Stanford, Princeton, Yale, M.I.T., Caltech, Carnegie Mellon, Berkeley, U.C.L.A., the University of Chicago, Georgia Tech, Cornell, Dartmouth, Southern Cal, Columbia, Northwestern, Penn, Michigan or any number of other top colleges with comparable or even better computer resources.
Mr. Gates wasn’t the only person who knew how to program in Basic; the language was developed a decade earlier by Dartmouth professors, and it was widely known by 1975, used in academics and industry. And what about all the master’s and Ph.D. students in electrical engineering and computer science who had even more computer expertise than Mr. Gates on the day the Popular Electronics article appeared? Any could have decided to abandon their studies and start a personal computer software company. And computer experts already working in industry and academia could have done the same.
But how many of them changed their life plans—and cut their sleep to near zero, essentially inhaling food so as not to let eating interfere with work—to throw themselves into writing Basic for the Altair? How many defied their parents, dropped out of college and moved to Albuquerque to work with the Altair? How many had Basic for the Altair written, debugged and ready to ship before anyone else?
Thousands of people could have done the same thing that Mr. Gates did, at the same time. But they didn’t.
The difference between Mr. Gates and similarly advantaged people is not luck. Mr. Gates went further, taking a confluence of lucky circumstances and creating a huge return on his luck. And this is the important difference.
Luck, good and bad, happens to everyone, whether we like it or not. But when we look at the 10Xers, we see people like Mr. Gates who recognize luck and seize it, leaders who grab luck events and make much more of them.
This ability to achieve a high ROL at pivotal moments has a huge multiplicative effect for 10Xers. They zoom out to recognize when a luck event has happened and to consider whether they should let it disrupt their plans. Imagine if Mr. Gates had said to Paul Allen after seeing the Popular Electronics article: “Well, Paul, I’m kind of focused on my studies here at Harvard right now. Let’s wait a few years, and then I’ll be ready to start.”
When we examined less successful companies, we saw a generally poor overall return on luck. Some of the comparison cases had extraordinary sequences of good luck yet showed a spectacular ability to fritter that luck away. When the time came to execute on their good fortune, they stumbled. They didn’t fail for lack of good luck. They failed for lack of superb execution.
WHILE getting a high return on good luck is an essential skill for 10Xers, getting a high return on bad luck can be a truly defining moment. Consider the 10X case of Progressive Insurance.
On Nov. 8, 1988, Peter Lewis, the chief executive, received news that shocked the insurance industry. California voters had passed Proposition 103, a punitive attack on car insurance companies. Prop 103 required 20 percent price reductions and refunds to customers, plunging a huge auto insurance market into chaos. Progressive had significant exposure, with nearly a quarter of its entire business from that one state—bang!—severely damaged by a 51 percent vote on a single day.
Mr. Lewis zoomed out to ask, “What the heck is going on?” He placed a call to a former Princeton classmate, Ralph Nader. Mr. Nader had long been a consumer rights activist, at one point leading a sort of special forces unit nicknamed Nader’s Raiders, and he had championed Proposition 103. The message that Mr. Lewis heard: People hate you. Or, in other words, people simply hated dealing with insurance companies, so they revolted, screaming with their votes.
“People were saying, ‘We hate your guts. We’re going to kill you. And we don’t give a damn,’ ” Mr. Lewis said.
Chastened by what he had heard, he called his staff together and told everyone, “Our customers actually hate us.” He challenged his team to create a better company.
Mr. Lewis came to see Proposition 103 as a gift, and he used it to deepen the company’s core purpose and to reduce the economic cost and trauma caused by auto accidents. The company would create its “immediate response” claims service: No matter when you had an accident, Progressive would be available—24 hours a day, 365 days a year. Claims adjusters would work from a fleet of vans and S.U.V.’s dispatched to policy holders’ homes or even directly to an accident scene.
By 1995, Progressive could note this achievement: in 80 percent of cases, its adjusters would have visited the customer, ready to issue a check within 24 hours of an accident.
In 1987, the year before Proposition 103, Progressive ranked No. 13 in the American private-passenger auto insurance market. By 2002, it had reached No. 4. Years later, Mr. Lewis called Proposition 103 “the best thing that ever happened to this company.”
Progressive and Mr. Lewis illustrate how 10Xers shine when clobbered by setbacks and misfortune, turning bad luck into good results. They use difficulty as a catalyst to deepen purpose, recommit to values, increase discipline, respond with creativity and heighten productive paranoia—translating fear into extensive preparation and calm, clearheaded action. Resilience, not luck, is the signature of greatness.
Nietzsche wrote, “What does not kill me, makes me stronger.” We all get bad luck. The question is how to use it to turn it into “one of the best things that ever happened,” to not let it become a psychological prison.
We came across a remarkable moment at the very start of the history of Southwest Airlines, described by its first chief executive, Lamar Muse, in his book, “Southwest Passage.”
“The very first Sunday morning of Southwest’s life, we narrowly escaped a disaster,” Mr. Muse wrote. “During the takeoff run, the right thrust-reverser deployed. Only the captain’s instantaneous reaction allowed him to recover control and make a tight turn for an emergency landing on one engine.”
What if the jet had smashed into the ground in the first week of building the company? Would there even be a Southwest Airlines today? If we all have some combination of both heads (lucky flips) and tails (unlucky flips), and if the ratio of heads to tails tends to even out over time, we need to be skilled, strong, prepared and resilient to endure the bad luck long enough to eventually get good luck. The Southwest pilot had to be skilled and prepared before the thrust-reverser deployed.
There’s an interesting asymmetry between good and bad luck. A single stroke of good luck, no matter how big, cannot by itself make a great company. But a single stroke of extremely bad luck, or an extended sequence of bad-luck events that creates a catastrophic outcome, can terminate the quest.
The 10Xers exercise productive paranoia, combined with empirical creativity and fanatic discipline, to create huge margins of safety. If you stay in the game long enough, good luck tends to return, but if you get knocked out, you’ll never have the chance to be lucky again. Luck favors the persistent, but you can persist only if you survive.
After finishing our luck analysis for “Great by Choice,” we realized that getting a high ROL required a new mental muscle. There are smart decisions and wise decisions. And one form of wisdom is the ability to judge when to let luck disrupt our plans. Not all time in life is equal. The question is, when the unequal moment comes, do we recognize it, or just let it slip? But, just as important, do we have the fanatic, obsessive discipline to keep marching, to push the opportunity to the extreme, to make the most of the chances we’re given?
Getting a high ROL requires throwing yourself at the luck event with ferocious intensity, disrupting your life and not letting up. Bill Gates didn’t just get a lucky break and cash in his chips. He kept pushing, driving, working—and sustained that effort for more than two decades. That’s not luck—that’s return on luck.

New Rules


By Thomas L. Friedman, NY Times, September 8, 2012
I just arrived in Shanghai, but I’m thinking about Estonia and wondering about something Presidents Clinton and Obama have been saying.
Wired magazine reported last week that public schools in Estonia are establishing a program for teaching first graders—and kids in all other grades—how to do computer programming. Wired said that the curriculum was created “because of the difficulty Estonian companies face in hiring programmers. Estonia has a burgeoning tech industry thanks in part to the success of Skype, which was developed in Estonia in 2003.”
The news from Estonia prompted The Guardian newspaper of London to publish an online poll asking its readers: “Children aged 7 to 16 are being given the opportunity to learn how to code in schools in Estonia, should U.K. school children be taught programming as part of their school day?” It’s fascinating to read about all this while visiting Shanghai, whose public school system in 2010 beat the rest of the world in math, science and reading in the global PISA exam of 15-year-olds. Will the Chinese respond by teaching programming to preschoolers?
All of this made me think Obama should stop using the phrase—first minted by Bill Clinton in 1992—that if you just “work hard and play by the rules” you should expect that the American system will deliver you a decent life and a chance for your children to have a better one. That mantra really resonates with me and, I am sure, with many voters. There is just one problem: It’s out of date.
The truth is, if you want a decent job that will lead to a decent life today you have to work harder, regularly reinvent yourself, obtain at least some form of postsecondary education, make sure that you’re engaged in lifelong learning and play by the rules.
Why? Because when Clinton first employed his phrase in 1992, the Internet was just emerging, virtually no one had e-mail and the cold war was just ending. In other words, we were still living in a closed system, a world of walls, which were just starting to come down. It was a world before Nafta and the full merger of globalization and the information technology revolution, a world in which unions and blue-collar manufacturing were still relatively strong, and where America could still write a lot of the rules that people played by.
That world is gone. It is now a more open system. Technology and globalization are wiping out lower-skilled jobs faster, while steadily raising the skill level required for new jobs. More than ever now, lifelong learning is the key to getting into, and staying in, the middle class.
There is a quote attributed to the futurist Alvin Toffler that captures this new reality: In the future “illiteracy will not be defined by those who cannot read and write, but by those who cannot learn and relearn.” Any form of standing still is deadly.
I covered the Republican convention, and I was impressed in watching my Times colleagues at how much their jobs have changed. Here’s what a reporter does in a typical day: report, file for the Web edition, file for The International Herald Tribune, tweet, update for the Web edition, report more, track other people’s tweets, do a Web-video spot and then write the story for the print paper. You want to be a Times reporter today? That’s your day. You have to work harder and smarter and develop new skills faster.

The incredible amount of oil burned unto today. Deadly experiments part two


by F.G.Helmke
 
Can you kill the Earth "by burning an oil lamp?" Let’s calculate:
Total oil produced up to date: 100 billion tons
One ton is one billion milligrams
That’s one hundred billion billions of milligrams of oil produced
(100 000 000 000 000 000 000 mg)

The atmosphere of the Earth: 4 billion cubic kilometers (at sea level conditions)
One cubic kilometer is one billion cubic meters
So the atmosphere contains four billion billions of cubic meters of air
(4 000 000 000 000 000 000 m³)

100 billion billions of milligrams divided by 4 billion billions of cubic meters 
That’s  25 milligrams of oil burned per cubic meter of air in our atmosphere.
100 000 000 000 000 000 000 mg
:   4 000 000 000 000 000 000 m³
= 25 mg/m³

  Now let’s do the following experiment: Get a one cubic meter cardboard box. Put you head inside and seal it. Take a syringe with 25 mg or about 33 ml of crude oil, put it into an oil lamp and light it. If you survive, keep on driving your car! If not, be sure you go to heaven! When you arrive there you’d better have a good apology why you allowed this to happen your planet!

Pressure cooker explodes. Potentially lethal experiment demonstrates effects of global warming


The sky is the limit. And we have reached it. 
F.G.Helmke
The distance from sea level up to the peak of Mount Everest is probably as much as from your home to where you work. If it were horizontal you could walk there in less than two hours. If it weren’t so rocky you could slide down there in forty minutes. That's not very high at all! But up there you have already 70% less oxygen. So as you see this World doesn't have an unlimited amount of air! To the contrary, the effective* thickness of the atmosphere is only 8.2km! (*measured at sea level conditions). That's from where you are right now to somewhere very near to where you are right now. 
So our atmosphere is actually as thin as a soap bubble in comparison to the size of the Earth! Just because you can't see its limit doesn't mean it doesn't exist and that you can pump an ever increasing amount of carbon dioxide into it. Scientists estimate that if nothing gets done temperatures will rise another 6 degrees Celsius long before the end of this century, and our world will simply be uninhabitable. And we all know as long as there is oil probably nothing will get done.                    
There is a very simple experiment you can do: put a pot of milk on your stove and start heating it up. Don’t turn off the stove. Just wait for what will happen. The result of this experiment will show you that you can’t heat up things indefinitely without serious consequences. 
Another good experiment is filling up a pressure cooker with lentils almost up to the brim and put it on the fire. This experiment will teach you that there is only one safe moment to turn off the fire, and that’s the very moment when you realize that you made a mistake. Then you have to leave the room, because he next moment it might explode just as mine did. Unfortunately this is exactly what we are doing to our planet. It’s now or forget it, buddy!
“They ate and drank and got married (or merry, and didn’t worry) until the day the flood came”, Jesus said about the people at the time of Noah. Mankind hasn’t changed since. But when God speaks about the end of the world he speaks about the end of this kind of world where greed and ignorance rule. Not the one he created. Jesus said the day it burns he will come back with a big fire extinguisher and rescue us! I suppose he would prefer to leave it up to us to take care of this beautiful creation, and not to intervene, but there seems to be not much of an alternative.

The Chocolate Machine That Can Improve Your Willpower


By Drake Bennett, Bloomberg Businessweek
What if someone told you they had invented a machine that sits on your desk and strengthens your self-control? What if they further told you that that machine worked by feeding you chocolates? You would assume that person was a small child, perhaps, or a late-night TV pitchman.
At a tech conference a week ago, however, a team of German psychologists and designers introduced to the world just such a device: the Chocolate Machine, “a transformational product to improve self-control strength.” The Chocolate Machine is very simple: a tube reminiscent of a tall sleek Pez dispenser that, every 40 to 60 minutes, releases a chocolate ball onto a person’s desk. The recipient could then eat it or put it back into the machine. When the subjects started the study, they were told that putting the chocolate back into the machine would help build their willpower. The machine had a counter that kept track of how many times the user put chocolates back in the tube. That’s it.
The concept behind the machine is something called ego depletion, a model for how self-control and decision-making works, most associated with the American psychologist Roy Baumeister. In the ego-depletion model, willpower is like a muscle: It can tire over time. In one famous study, Baumeister had people eat radishes while leaving a plate of chocolate-chip cookies untouched in front of them. Then he gave them an unsolvable puzzle to do. The people who had denied themselves the chocolate chip cookies, he found, gave up on the puzzle faster than those who had been able to indulge their sweet tooth. Forcing themselves to eat the radishes had depleted their willpower.
The good news is that willpower, also like a muscle, can be strengthened with exercise. That’s what the Chocolate Machine is supposed to do: each chocolate put back in the machine is like a set of sit-ups for your self-control.
According to Marc Hassenzahl, a psychologist who helped design the Chocolate Machine, the device was an attempt to design something whimsical but effective—something that would work not by stick and carrot but by a sort of gentle suasion. “It’s not rewarding good behavior and punishing bad behavior,” he says. “It’s like a friend who’s commenting on your behavior and saying: ‘You’re doing it again; wouldn’t it be better if you did it this way instead?’”
There are as yet no plans to mass-produce the Chocolate Machine, but Hassenzahl already envisions a whole category of devices meant to prod people toward virtue in similar ways—he’s also built a reading light that has to be periodically touched to stay on, reminding users that the light isn’t free.
So does the Chocolate Machine work? The experimental group that Hassenzahl and his collaborators tried the machine on was small: just 24 people, with 10 using the machine and the rest in a control group. Of those 10, however, seven found that the machine improved their self-control, and they proved more persistent at doing difficult mental challenges than the control group.
“It’s not Nobel Prize material,” Hassenzahl says, “but it’s encouraging.”
