American scientists have proven that chewing gum can improve a student's academic performance. A study by Craig Johnson from Houston College of Medicine confirmed that chewing gum students in the math class are performing better in standardized math tests and will get better grades in their classes at the end of the semester.
The study included 4 math lessons - 108 students between the ages of 13 and 16. About half of them chewed at school, on exams, and at home. 86% of the time they spent in math classes and 36% of the time they spent on homework was chewed by at least one "note". The other half of the students enjoyed chewing gum. After 14 weeks, chewing students increased their TACS by 3% in the Knowledge and Skills Assessment Test (TAKS). In another mathematical test, the difference between the results of the two groups could not be determined. However, at the end of the semester, the students who chewed gum received the best marks. We must not forget that chewing gum is banned in most American schools.
