Do teachers have the right to yell at students?

No, teachers do not have the right to yell at students. While maintaining order and discipline in a classroom is a necessary part of a teacher's job, yelling is generally considered unprofessional and ineffective. Many schools have policies explicitly prohibiting yelling or other forms of verbal abuse. Furthermore, yelling can be considered a form of verbal abuse and can create a hostile learning environment. More effective classroom management techniques focus on positive reinforcement and constructive communication.
