    Teaching Math,Teaching Anxiety
    In a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.
    If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.
    Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.
    The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.
    The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.
    Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.
    “This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.

    What is the result of the research at the University of Chicago,according to the first paragraph?
    A:Girls comfortable with their own math skills are better than boys at math.
    B: Girls uncomfortable with their own math skills are not as good as boys at math.
    C: Female teachers'math skills have influence over girl students'math skills.
    D: Female teachers'confidence in their math skills is related to girls'math skills.

    答案:D

    Teaching Math,Teaching Anxiety
    In a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship be-tween what female teachers think and what female students learn:If a female teacher is un-comfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.

On aver-age,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math su- perstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety(与female teachers' math anxiety呼应).定位线索词集中出现在第六段最后一句中,因此重点关注这个句子。该 句意为“在关于是否认为数学高手应该是男孩的测试中,有20个女孩认为男孩数学比女孩好,这20个女孩的老师都是女性,而且都对数学有焦虑感”。这说明女教师对数学的焦虑感会影响女学生对自己数学能力的信心。该句的前一句提到“一般来说,教女孩子的教师对数学有焦虑感,那么女孩子们在学年结束时测试得分会比其他的女孩要低”。结合这两个句子的意思可以得出这样的结论:女教师对数学的焦虑感会影响女学生对自己数学能力的信心,并最终影响女学生的数学成绩,因此该题答案为A项“证明在女教师对数学的焦虑感和女学生的数学成绩之间有密切的联系”。

    In a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.
    If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.
    Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.
    The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.
    The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.
    Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.
    “This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.

    The sixth paragraph tells us that the research findings______.
    A:prove a strong link between female teachers'math anxiety and their female students' math achievements
    B: show that male students are less likely to be affected by their math anxiety than female students
    C: provide strong evidence that math superstars are more likely to be males than females

    Teaching Math,Teaching Anxiety

In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up be-lieving that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.
    Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for every-one. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.
    The new study found that when a teacher has anxiety about math,that feeling can influ-

On aver-age,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math su- perstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety(与female teachers' math anxiety呼应).定位线索词集中出现在第六段最后一句中,因此重点关注这个句子。该 句意为“在关于是否认为数学高手应该是男孩的测试中,有20个女孩认为男孩数学比女孩好,这20个女孩的老师都是女性,而且都对数学有焦虑感”。这说明女教师对数学的焦虑感会影响女学生对自己数学能力的信心。该句的前一句提到“一般来说,教女孩子的教师对数学有焦虑感,那么女孩子们在学年结束时测试得分会比其他的女孩要低”。结合这两个句子的意思可以得出这样的结论:女教师对数学的焦虑感会影响女学生对自己数学能力的信心,并最终影响女学生的数学成绩,因此该题答案为A项“证明在女教师对数学的焦虑感和女学生的数学成绩之间有密切的联系”。
