Professors may establish social relationships with students outside of the classroom,but in the classroom they play the role of an instructor.A professor may have coffee with students one day but the next day he may expect them to meet a deadline for a paper or to be prepared for a discussion or an exam.The professor may give extra attention,outside of class,to a student in need of help,but probably will not treat him or her differently when it comes to evaluating academic work.Professors have several roles in relation to students; they may be counselors and friends as well as teachers.Students must realize that when a teacher's role changes,they should change their behavior and attitude accordingly.
