friends vs teachers impact on students
It is believed that a student's behavior and the result can be influenced by some causes. And I would argue that friends have more effects on them than teachers.
To begin with, getting on well with classmates has a strong positive influence on students. Because of the educational condition, they spend more time with peers than teachers. They just meet the teacher in the restricted period while most of the school time is spent interacting with their friends. For example, just in Math periods, students are able to communicate with Math mentors, but they will meet other students in all periods left. This leads to their behavior can be influenced more effectively by peers because of longer interaction.
On the other hand, the relationship between classmates can create a competitive environment. Students would prefer to express themselves and do their best to excel. They may bury themselves in their books in order to overtake their opponents. As a result, the academic outcomes could be improved. For instance, league tables with scholarships are a good way to create motivation for students to compete with others.
In conclusion, in my opinion, the positive changes on students are mostly referred to their peers than teachers.
