During the first day of class, the instructor must carefully discuss the policies which students must follow. I firmly believe on the importance of this. Guidelines on student actions and behaviors are established . One of this is showing respect by paying attention and actively listening to the teacher or any student. The teacher must maintain order and be in control of the class as part of his role as a manager and leader (some undesirable situations - teachers allowing students to talk at the same time , sleeping inside the classroom ,unprofessional conduct ,inappropriate behavior ,disrespect , foul language etc.). When teachers are not consistent with the implementation of rules and policies inside the classroom , chaos and disorder can set in which is no longer conducive for learning.
