28、 Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn: If a female女 teacher is uncomfortable 不安的,不自在的with her own math skills, then her female students are more likely to believe that boys are better than girls at math.在最新一項(xiàng)關(guān)于小學(xué)生學(xué)

29、數(shù)學(xué)的研究中，芝加哥大學(xué)的心理學(xué)家Sian Beilock和Susan Levine 發(fā)現(xiàn)，女教師的想法和女學(xué)生的學(xué)習(xí)之間有著驚人的聯(lián)系：如果女教師對(duì)自己的數(shù)學(xué)能力感到焦慮，她的女學(xué)生很可能認(rèn)為男孩子數(shù)學(xué)比女孩學(xué)得更好。2.If these girls keep getting math-anxious female teachers2 in later grades, it may create a snowball effect on their math achievement3, said Levine. In other words, girls may end up learnin

30、g math anxiety from their teachers4. 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.如果一直由對(duì)數(shù)學(xué)有焦慮的女教師教授數(shù)學(xué)，就會(huì)對(duì)她們的數(shù)學(xué)成績(jī)產(chǎn)生雪球效應(yīng)，Levine說。換言之，女孩子們最后從老師那里獲得的是對(duì)數(shù)學(xué)的焦慮。該研究表明，如

31、果女孩子們?cè)谝粋€(gè)認(rèn)為男孩比女孩數(shù)學(xué)好的環(huán)境中成長，那么她們的數(shù)學(xué)可能會(huì)不如在更自信的狀態(tài)下學(xué)得好。3.Just as students find certain subjects to be difficult, teachers can find certain subjects to be difficult to learn - and teach. The subject of math can be particularly difficult for everyone. Researchers use the word anxiety to describe such feelin

32、gs: anxiety is uneasiness or worry.如同學(xué)生，教師也會(huì)覺得某些學(xué)科難學(xué)和難教，數(shù)學(xué)可能對(duì)每一個(gè)人來說尤其難。這就是研究者所言的焦慮：不自信或擔(dān)心。4.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

33、 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.此研究發(fā)現(xiàn)，教師對(duì)數(shù)學(xué)的焦慮能夠傳染給她的女學(xué)生們。該研究的研究對(duì)象包括65個(gè)女孩，52個(gè)男孩和17位在中西部教一二年級(jí)的教師。學(xué)生們?cè)趯W(xué)年的開始和結(jié)束時(shí)都進(jìn)行數(shù)學(xué)測(cè)試，研究者們比較得分。5.The researchers also gave the students

34、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 recei

35、pt銷售清單5. A teacher who got nervous looking at the numbers on a sales receipt銷售清單, for example,was probably anxious about math.研究者們測(cè)試學(xué)生是否認(rèn)為數(shù)學(xué)明星一定會(huì)是男孩。然后研究者們測(cè)試教師，試圖找出哪些教師對(duì)數(shù)學(xué)感到焦慮，研究者們問教師們當(dāng)碰到數(shù)學(xué)問題諸如閱讀銷售清單時(shí)的感受，如果一位教師一看到銷售清單的數(shù)字就感到緊張，那么她很可能對(duì)數(shù)學(xué)存在焦慮。6. Boys,on average,were unaffected by a teachers anxiety. On

36、 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 - and all of these girls had been

37、taught by female teachers who had math anxiety.平均來說，教師的焦慮不會(huì)影響到男孩子。但是，一般說來，如果教女孩子的教師有數(shù)學(xué)焦慮癥，那么女孩子們?cè)趯W(xué)年結(jié)束時(shí)測(cè)試得分比其他的女孩要低。另外，在關(guān)于是否認(rèn)為數(shù)學(xué)明星應(yīng)該是男孩的測(cè)試中，有20個(gè)女孩認(rèn)為男孩數(shù)學(xué)比女孩好，這20個(gè)女孩的老師都是女性，且都患有數(shù)學(xué)焦慮癥。This is an interesting study, but the results need to be interpreted解釋 as preliminary and in need of replication with a
