The researchers analyzed data from over 1 million students in California who took the state's standardized math test. They found that girls who lived in areas with high levels of air pollution scored lower on the test than girls who lived in areas with low levels of air pollution. The difference was even more pronounced for girls from low-income families.
The researchers believe that air pollution may harm the development of the brain, which could lead to lower math scores. Air pollution can also cause inflammation and oxidative stress, which have been linked to cognitive impairment.
The study's findings are consistent with previous research that has found that air pollution can harm children's health and academic performance. However, this is the first study to examine the link between air pollution and math performance in girls specifically.
The study's authors say that their findings have implications for public policy. They argue that reducing air pollution could help to improve the math performance of girls, which could lead to increased opportunities for them in STEM fields.
"Our findings suggest that air pollution may be an important factor in the gender gap in math achievement," said study co-author Dr. Janet Currie. "Reducing air pollution could help to level the playing field for girls and improve their opportunities for success in STEM fields."
The study's findings are also consistent with the theory that environment, not innate ability, determines how well girls do in math class. This theory has been gaining traction in recent years, as more and more research has shown that girls are just as capable as boys at math when given the same opportunities.
The study's findings are a reminder that the environment can have a significant impact on children's health and academic performance. By reducing air pollution, we can help to improve the math performance of girls and give them a better chance of success in STEM fields.
