研究發(fā)現(xiàn)：天氣太熱真的會(huì)影響考試成績(jī)

哈佛大學(xué)聯(lián)合幾所著名高校開(kāi)展了一項(xiàng)大型研究，只為了調(diào)查高溫天氣對(duì)學(xué)生成績(jī)的影響。結(jié)果顯示，天氣太熱真的會(huì)讓學(xué)生成績(jī)普遍降低，解決辦法就是，多開(kāi)空調(diào)。

In years with hotter weather pupils are likely to perform less well in exams, says a major study from researchers at Harvard and other US universities.

哈佛等美國(guó)大學(xué)的研究人員開(kāi)展的大型研究指出，在天氣炎熱的年份，學(xué)生們的考試成績(jī)會(huì)變差。

There is a "significant" link between higher temperatures and lower school achievement, say economic researchers.

這些經(jīng)濟(jì)學(xué)研究員稱，高溫天氣和考試成績(jī)下降之間有“重大”關(guān)聯(lián)。

An analysis of test scores of 10 million US secondary school students over 13 years shows hot weather has a negative impact on results.

這項(xiàng)研究在分析了1000萬(wàn)名美國(guó)中學(xué)生13年間的考試成績(jī)后發(fā)現(xiàn)，炎熱天氣對(duì)考試成績(jī)有負(fù)面影響。

The study says a practical response could be to use more air conditioning.

研究指出，比較實(shí)際的應(yīng)對(duì)措施就是多開(kāi)空調(diào)。

Students taking exams in a summer heatwave might have always complained that they were hampered by the sweltering weather.

But this study, from academics at Harvard, the University of California Los Angeles (UCLA) and Georgia State University, claims to have produced the first clear evidence showing that when temperatures go up, school performance goes down.

哈佛大學(xué)、加州大學(xué)洛杉磯分校和喬治亞州立大學(xué)的學(xué)者開(kāi)展的這項(xiàng)研究聲稱，首次有明顯證據(jù)表明，氣溫升高時(shí)，學(xué)生考試成績(jī)會(huì)下降。

Researchers have tracked how secondary school students performed in tests in different years, between 2001 and 2014, across the different climates and weather patterns within the US.

研究人員追蹤了2001年到2014年間這些中學(xué)生在不同年份的考試成績(jī)，這些中學(xué)位于美國(guó)不同的氣候帶，天氣模式也不同。

The study, published by the US National Bureau of Economic Research, found that students were more likely to have lower scores in years with higher temperatures and better results in cooler years.

美國(guó)國(guó)家經(jīng)濟(jì)研究局發(fā)布的這項(xiàng)研究發(fā)現(xiàn)，氣溫高的年份里學(xué)生的考試成績(jī)更差，而天氣涼爽的年份里學(xué)生的考試成績(jī)更好。

This applied across the many different types of climate - whether in cooler northern US states or in the southern states where temperatures are typically much higher.

這一結(jié)論適用于美國(guó)不同氣候帶的學(xué)校，無(wú)論是在涼爽一些的北部州，還是在氣溫通常高得多的南部州。

The study, Heat and Learning, suggested that hotter weather made it harder to study in lessons in school and to concentrate on homework out of school.

這項(xiàng)名為“高溫與學(xué)習(xí)”的研究指出，天熱的時(shí)候，學(xué)生在學(xué)校上課更困難，在校外做作業(yè)時(shí)也更難以集中注意力。

Researchers calculated that for every 0.55C increase in average temperature over the year, there was a 1% fall in learning.

根據(jù)研究人員的計(jì)算，一年的平均氣溫每升高0.55攝氏度，學(xué)習(xí)成績(jī)就會(huì)下降1%。

Colder days did not seem to damage achievement - but the negative impact began to be measurable as temperatures rose above 21C.

冷天似乎不會(huì)影響學(xué)習(xí)成績(jī)，但是當(dāng)氣溫升到21攝氏度以上時(shí)，負(fù)面影響就開(kāi)始顯現(xiàn)。

The reduction in learning accelerated once temperatures rose above 32C and even more so above 38C.

一旦氣溫升到32攝氏度以上，學(xué)習(xí)成績(jī)的下滑速度就加快，氣溫升到38度以上后更是如此。

Joshua Goodman, associate professor at the Harvard Kennedy School of Government, and his co-authors provide evidence that the "heat's disruption of instruction or homework time is responsible for the observed drop in test scores".

哈佛大學(xué)肯尼迪政府學(xué)院的副教授喬舒亞·古德曼和他的合著者提出了證據(jù)，證明“高溫對(duì)上課和作業(yè)時(shí)間的影響導(dǎo)致了考試成績(jī)的明顯下降”。

He says students were incrementally more likely to be "distracted, agitated and find it harder to focus".

他說(shuō)，學(xué)生更可能“分心、躁動(dòng)、難以集中注意力”，這一現(xiàn)象會(huì)隨著溫度升高而加劇。

Mr Goodman says the findings also raise bigger questions about whether climate change and global warming will have implications for school achievement.

古德曼說(shuō)，研究結(jié)果還提出了一個(gè)更大的問(wèn)題，即氣候變化和全球變暖是否會(huì)影響學(xué)生的成績(jī)。

Mr Goodman says the researchers also want to examine the long-term consequences of a hot year on a cohort of students.

古德曼說(shuō)，研究人員還想調(diào)查高溫年份對(duì)同一屆學(xué)生的長(zhǎng)期影響。

If students happen to take important exams in a heatwave year, does that mean they are more likely to miss out on exam results and university places?

如果學(xué)生碰巧在高溫年份參加重要考試，這是否意味著他們更可能考試失利，錯(cuò)過(guò)大學(xué)入學(xué)機(jī)會(huì)呢?

Mr Goodman says that policymakers and parents have under-estimated the significance of temperatures in schools and overheated classrooms.

古德曼說(shuō)，決策者和家長(zhǎng)們都低估了學(xué)校溫度以及教室溫度過(guò)高的影響。

"Teachers and students already know it's a problem - because they've had to live it," he said.
