题目：
| Are we "Math People" or "English People" The earliest hint of verbal dexterity is enough to earn a language ability label while the slightest struggle with a mathematical concept might as well come with a forehead stamped "mathematically inept." "The common wisdom in the United States is that mathematical ability is somehow innate, and there are people who, no matter how hard they try, will not be able to achieve in mathematics," said A1 Cuoco, director of the Center for Mathematics Education at Educational Department Center Inc, a nonprofit in Newton, who has taught math since the late 1960s. Struggling in math is socially acceptable, while having trouble reading is reason for worry. Why the stigma around numbers Cuoco said the belief that you’ve got a math gene is "an American phenomenon." In the United States, he said, "kids from a very young age are put into two categories: those who get it and those who don’t. In other countries, the perspective is that if you work hard and apply yourself, anyone can achieve mathematics at an advanced high school level." Abby Coyle, 15, of Newton, a sophomore at Dana Hall School, an all-girls campus in Wellesley, has long noticed educators putting math and English at opposite poles. "It seems there is always a distinct classification between math and science and English and social studies," said Coyle. Part of making your way through elementary school, she said, is figuring out if you’re better at math or English. "Once you fit into one, you don’t concentrate on the other side," said Coyle, who said it has taken effort to see herself as good at both. The cultural divide around math is not just about sorting students into math-focused and English-focused, but to make assumptions based on gender. Are boys better at math Do girls soar in English These may be common presumptions, but research suggests. |
