A new study out this month suggests one of the biggest things that can be done to fix poor performing schools is making sure every classroom has air conditioning. It has long been known that the warmer a country is, the lower its economic output, but it seems that is also true for academic success.
A team of researchers led by Harvard University recently linked daily weather data to the test scores of some 10 million high school students who took college entrance practice exams multiple times between 2001 and 2014 and found that, indeed, a hot classroom can negatively impact performance.
