Remember when Barbie whined that “math is hard.” Maybe you got annoyed at hearing a popular female doll say that to little girls. Or maybe you also had a nagging suspicion that, in fact, boys are better at math. Well, the latest research is in, and the answer is a resounding no: boys are not more math savvy. The finding appears in the July 25 issue of the journal Science. 

    Janet Hyde at the University of Wisconsin-Madison led the study. The group dug through piles of information from seven million students tested through the No Child Left Behind program across ten states. Researchers had detailed personal info on the test takers. Researchers checked out math tests in different grades. They took the average. No difference. Some critics have said that the difference only shows up among the highest levels of math skills. So the team checked out the most gifted children. Again, no difference. From any angle, girls measured up to boys. Still, there’s a lack of women in the highest levels of professional math, engineering and physics. Some have said that’s because of an innate difference in math ability. But the new research shows that that explanation just doesn’t add up.

    你一定還記得芭比娃娃曾抱怨“數(shù)學(xué)很難”�；蛟S你很討厭聽(tīng)到一個(gè)大眾喜愛(ài)的玩具女娃娃對(duì)小女孩們這樣說(shuō)。你也可能憤憤不平地懷疑男孩子真就是比女孩子數(shù)學(xué)好。最新的研究出來(lái)了，答案完全是否定的：男孩子在數(shù)學(xué)上未必比女孩子聰明。這項(xiàng)研究發(fā)表在7月25日的《科學(xué)》雜志上。

    威斯康星大學(xué)麥迪遜分校的珍妮特•海德領(lǐng)導(dǎo)了這項(xiàng)研究。這個(gè)研究小組分析了來(lái)自十個(gè)州多達(dá)7百萬(wàn)學(xué)生的信息，這些學(xué)生的考試是通過(guò)《不讓一個(gè)兒童落后》計(jì)劃進(jìn)行的。研究人員掌握參加考試學(xué)生的詳細(xì)個(gè)人信息。他們分析檢驗(yàn)了不同年級(jí)的數(shù)學(xué)考試成績(jī)。結(jié)果表明男孩女孩都取得平均成績(jī)，并沒(méi)有男女差別。有些評(píng)論家說(shuō)男女成績(jī)的差別只在最高級(jí)別的數(shù)學(xué)技巧上顯現(xiàn)出來(lái)。因此這個(gè)研究小組對(duì)那些最有天分的兒童們進(jìn)行了分析檢驗(yàn)。結(jié)果仍然是沒(méi)有男女之別。從任何角度講，女孩子和男孩子的數(shù)學(xué)能力相同。但是，在對(duì)數(shù)學(xué)要求最高的工程和物理職業(yè)領(lǐng)域里，女性仍然不多。有些人認(rèn)為這是由于男女在數(shù)學(xué)能力方面天生有別。但是這項(xiàng)最新的研究表明這樣的解釋是站不住腳的。
