As educators have known for a long, long time, there is no magic solution to improve academic achievement for all students. Experienced teachers and engaging curriculum long way to go, but external factors often play a big role as well. Now a new study addresses the curious link between student and smart that many children are forced to deal with each and every morning a school bus fumes.

The study, which was published in Economy Bulletin EducationCompared to the standardized test scores of students from school districts throughout Georgia. Unexpected data showed that school districts that have invested in the modernization of school buses with emission reduction systems had higher test scores than those who did not.

Anyone who has traveled in the school bus, knows what it's like to sit in a low cloud of diesel fumes. It is unpleasant to say the least, and the researchers believe that this is a forced exposure to air pollution has a major negative impact on students in school districts that have yet to upgrade their buses.

When comparing the results of tests, the researchers found that schools with clean-burning tires went much higher test scores in English and math results slightly higher.

"We found a strong and convincing evidence that the bus retrofitting schools has led to an increase in performance, especially for the English assessment tests," the researchers explain. "According to our estimates, if the area of ​​upgrades its entire bus fleet, the impact on the English test would be a little bit more, than the effect comes from the teacher rookie to one of the five years of experience. "

Trying not to draw a link, if there were none, other factors are also considered in the study, such as body mass index, to exclude the possibility that school buses have been modified with a "healthy" and thus more emphasis on success. The team found no correlation between schools with clean buses and rooms BMI further suggests that the management of air pollution is really a & # 39 is the cause of increasing performance.

Available modifications to existing tires, the researchers are relatively inexpensive and can reduce harmful contaminants, up to 95 percent and gradually roll out to most of the territory of Georgia and many other states.
