Research on The Relationship between Air Pollution and College Students' exam Scores

摘要

The purpose of this study is to explore the influence of air pollution on college students' exam scores. In the experiment, a control environment of whether the air is purified or not was set up. In the two environments, 160 freshmen from a top 20 university in China took the CET-4, which is commonly taken by Chinese college students. By analyzing the air pollutants concentration and the students' scores, this study explores the relationship between the changes of pollutants' concentration and the changes of scores, and explores the influence of pollutants' concentration on the score prediction. The results show that air pollution does affect students' exam scores. After adding the air pollutants concentration data, the score prediction accuracy of the reading comprehension questions which need a longer time to think about is significantly improved.
