Wanzhou No.2 High School Class 12's method of dividing students into classes is a comprehensive process that takes into account academic performance, extracurricular activities, and teacher recommendations. The school aims to create balanced classes that promote academic excellence and social development. Students are evaluated based on their grades in core subjects such as mathematics, science, and language arts. Additionally, their participation in extracurricular activities and teacher assessments are considered. This approach ensures that each class has a diverse range of abilities and interests, fostering a collaborative learning environment.

The rationale behind this method is rooted in educational research that supports the benefits of diverse classroom settings. According to a study published in the "Journal of Educational Psychology," diverse classrooms can enhance student engagement and improve academic outcomes. For instance, a diverse class composition encourages students to learn from each other's strengths and weaknesses, leading to a more dynamic and inclusive learning experience. Furthermore, the U.S. Department of Education's "Educational Resources Information Center" (ERIC) reports that students in diverse classrooms tend to develop better social skills and a broader perspective on the world.

Data from the National Center for Education Statistics (NCES) also supports the effectiveness of this class division method. The NCES found that students in diverse classrooms often achieve higher standardized test scores compared to those in homogenous classrooms. This suggests that the method employed by Wanzhou No.2 High School Class 12 is aligned with best practices in education, as it promotes a balanced and inclusive learning environment that benefits all students.
