### THE REALITY IS THEY'LL NEVER NEED TO USE MATH IN THEIR LIVES...:

Why Do Americans Stink at Math? (ELIZABETH GREEN, JULY 23, 2014, NY Times Magazine)

When Akihiko Takahashi was a junior in college in 1978, he was like most of the other students at his university in suburban Tokyo. He had a vague sense of wanting to accomplish something but no clue what that something should be. But that spring he met a man who would become his mentor, and this relationship set the course of his entire career.Takeshi Matsuyama was an elementary-school teacher, but like a small number of instructors in Japan, he taught not just young children but also college students who wanted to become teachers. At the university-affiliated elementary school where Matsuyama taught, he turned his classroom into a kind of laboratory, concocting and trying out new teaching ideas. When Takahashi met him, Matsuyama was in the middle of his boldest experiment yet -- revolutionizing the way students learned math by radically changing the way teachers taught it.4Instead of having students memorize and then practice endless lists of equations -- which Takahashi remembered from his own days in school -- Matsuyama taught his college students to encourage passionate discussions among children so they would come to uncover math's procedures, properties and proofs for themselves. One day, for example, the young students would derive the formula for finding the area of a rectangle; the next, they would use what they learned to do the same for parallelograms. Taught this new way, math itself seemed transformed. It was not dull misery but challenging, stimulating and even fun.Takahashi quickly became a convert. He discovered that these ideas came from reformers in the United States, and he dedicated himself to learning to teach like an American. Over the next 12 years, as the Japanese educational system embraced this more vibrant approach to math, Takahashi taught first through sixth grade. Teaching, and thinking about teaching, was practically all he did. A quiet man with calm, smiling eyes, his passion for a new kind of math instruction could take his colleagues by surprise. "He looks very gentle and kind," Kazuyuki Shirai, a fellow math teacher, told me through a translator. "But when he starts talking about math, everything changes."Takahashi was especially enthralled with an American group called the National Council of Teachers of Mathematics, or N.C.T.M., which published manifestoes throughout the 1980s, prescribing radical changes in the teaching of math. Spending late nights at school, Takahashi read every one. Like many professionals in Japan, teachers often said they did their work in the name of their mentor. It was as if Takahashi bore two influences: Matsuyama and the American reformers.Takahashi, who is 58, became one of his country's leading math teachers, once attracting 1,000 observers to a public lesson. He participated in a classroom equivalent of "Iron Chef," the popular Japanese television show. But in 1991, when he got the opportunity to take a new job in America, teaching at a school run by the Japanese Education Ministry for expats in Chicago, he did not hesitate. With his wife, a graphic designer, he left his friends, family, colleagues -- everything he knew -- and moved to the United States, eager to be at the center of the new math.As soon as he arrived, he started spending his days off visiting American schools. One of the first math classes he observed gave him such a jolt that he assumed there must have been some kind of mistake. The class looked exactly like his own memories of school. "I thought, Well, that's only this class," Takahashi said. But the next class looked like the first, and so did the next and the one after that. The Americans might have invented the world's best methods for teaching math to children, but it was difficult to find anyone actually using them.It wasn't the first time that Americans had dreamed up a better way to teach math and then failed to implement it. The same pattern played out in the 1960s, when schools gripped by a post-Sputnik inferiority complex unveiled an ambitious "new math," only to find, a few years later, that nothing actually changed. In fact, efforts to introduce a better way of teaching math stretch back to the 1800s. The story is the same every time: a big, excited push, followed by mass confusion and then a return to conventional practices.The trouble always starts when teachers are told to put innovative ideas into practice without much guidance on how to do it. In the hands of unprepared teachers, the reforms turn to nonsense, perplexing students more than helping them. One 1965 Peanuts cartoon depicts the young blond-haired Sally struggling to understand her new-math assignment: "Sets . . . one to one matching . . . equivalent sets . . . sets of one . . . sets of two . . . renaming two. . . ." After persisting for three valiant frames, she throws back her head and bursts into tears: "All I want to know is, how much is two and two?"Today the frustrating descent from good intentions to tears is playing out once again, as states across the country carry out the latest wave of math reforms: the Common Core. A new set of academic standards developed to replace states' individually designed learning goals, the Common Core math standards are like earlier math reforms, only further refined and more ambitious. Whereas previous movements found teachers haphazardly, through organizations like Takahashi's beloved N.C.T.M. math-teacher group, the Common Core has a broader reach. A group of governors and education chiefs from 48 states initiated the writing of the standards, for both math and language arts, in 2009. The same year, the Obama administration encouraged the idea, making the adoption of rigorous "common standards" a criterion for receiving a portion of the more than $4 billion in Race to the Top grants. Forty-three states have adopted the standards.The opportunity to change the way math is taught, as N.C.T.M. declared in its endorsement of the Common Core standards, is "unprecedented." And yet, once again, the reforms have arrived without any good system for helping teachers learn to teach them. Responding to a recent survey by Education Week, teachers said they had typically spent fewer than four days in Common Core training, and that included training for the language-arts standards as well as the math.Carefully taught, the assignments can help make math more concrete. Students don't just memorize their times tables and addition facts but also understand how arithmetic works and how to apply it to real-life situations. But in practice, most teachers are unprepared and children are baffled, leaving parents furious. The comedian Louis C.K. parodied his daughters' homework in an appearance on "The Late Show With David Letterman": "It's like, Bill has three goldfish. He buys two more. How many dogs live in London?"The inadequate implementation can make math reforms seem like the most absurd form of policy change -- one that creates a whole new problem to solve. Why try something we've failed at a half-dozen times before, only to watch it backfire? Just four years after the standards were first released, this argument has gained traction on both sides of the aisle. Since March, four Republican governors have opposed the standards. In New York, a Republican candidate is trying to establish another ballot line, called Stop Common Core, for the November gubernatorial election. On the left, meanwhile, teachers' unions in Chicago and New York have opposed the reforms.The fact that countries like Japan have implemented a similar approach with great success offers little consolation when the results here seem so dreadful.
