introduction In today's society, schools have an important impact on students' learning and living environment, and one of the important aspects is the student's dress. Although there is a relatively high degree of freedom in individual dress, more and more schools have begun to make uniforms mandatory for students. Such an approach is not an unreasonable demand, but a decision based on scientific and practical evidence. Below, we'll explore in detail what the evidence reveals about why students should wear school uniforms. 1. Uniform dress code helps students develop a sense of collective pride First of all, wearing a school uniform can help students develop a sense of collective pride. The uniform dress code represents the inheritance and development of the school culture, and it represents the identity and sense of belonging of the students. When students wear the same uniform, they will realise that they are part of the school and that their behaviour and speech will affect the reputation and image of the school. This awareness helps to develop a sense of responsibility and honor in students. Second, school uniforms help to reduce the problem of comparison and distraction among students Second, wearing school uniforms can help reduce comparisons between students. In primary and secondary schools, students often have a strong pursuit of material and brand, and if they do not wear school uniforms, students may have a comparison mentality because of different clothes, which will not only distract students' attention, but also may cause unnecessary contradictions and conflicts. School uniforms can prevent this from happening and allow students to focus more on their studies. 3. School uniforms help to form a campus cultural atmosphere In addition, school uniforms are also an important part of campus culture. Students wearing school uniforms walking around the campus have also formed the inheritance and development of campus culture. School uniforms can help students better integrate into the campus culture and make them love school and learning more. At the same time, the school uniform can also be used as a cultural symbol, representing the tradition and spirit of the school. Fourth, scientific research has shown that wearing school uniforms can help improve students' academic performance The latest scientific research also shows that wearing a school uniform can have a positive impact on students' academic performance. One study found that students who wore school uniforms generally had higher attendance and academic performance. This may be because in the environment of wearing school uniforms, students pay more attention to the responsibility and sense of mission of learning, and are more able to form good learning attitudes and habits. At the same time, the uniformity and standardization of school uniforms can also create a stable and safe learning environment for students, helping to reduce distractions and stress. This helps to improve the concentration and efficiency of students' learning, which in turn further promotes students' academic development. Another study found that students who wore school uniforms were more likely to respect school rules and regulations and teachers' teachings, and were more likely to develop good teacher-student relationships and interactions. In such an environment, students' learning enthusiasm and creativity are also better stimulated and cultivated. Such relationships can continue to influence students' entire academic life and lay a good foundation for their future work and life. 5. ConclusionsIn general, the view that "students should wear school uniforms" is based on a series of evidence and scientific research. From the perspective of cultivating students' sense of collective honor, reducing the phenomenon of comparison, forming a campus cultural atmosphere, and improving students' academic performance, wearing school uniforms has important significance and role. Therefore, schools should encourage students to wear school uniforms to create a stable, safe and conducive learning environment, and at the same time help students form good values and outlook on life, so as to lay a solid foundation for their future development.
