This group of PE teachers not only make the students in Naperville school district the healthiest children in America, but also make them the smartest children.

Only at the end of the first half of the semester, students' reading comprehension ability improved by 17%, and the average score exceeded the state average. However, compared with TIMSS, these achievements are simply dwarfed.

TIMSS is an exam that brings together outstanding students from all over the world to examine mathematics and science. Chinese mainland, Hongkong, China, Taiwan Province, China, Japanese, Singaporean and other places have always taken the lead in this global unified examination. The performance of American students worries the elites, and they feel that the educational gap between the United States and Asian countries is widening. However, after the promotion of the new physical education class, the students in Naperville got the first place in science and the sixth place in mathematics in this test.

In addition to becoming smarter and getting better grades, the students also gained the teamwork ability, problem-solving ability and anti-risk ability that every parent wants their children to have in the physical education class. On the 7-meter-high and 3-meter-wide climbing wall, blindfolded climbers rely on their peers' instructions to reach one climbing point after another. This wall is an excellent place to learn leadership.

When the experience of Naperville High School was extended to poorer school districts, people discovered the new benefits of this course: the number of violations such as school violence dropped from 228 to 95 every year.

Small courses, big principles

Behind the case of Naperville High School lies the principle of biological neurology. Research shows that exercise provides a unique stimulus for the body, which creates an environment for the brain to be prepared, willing and able to learn.
