Many instructors believe that an informal, relaxed classroom environment is good to learning and innovation. It is not uncommon for students to have easygoing and friendly relationships with their professors. The casual(随和的) professor is not necessarily a poor one and is still respected by students. Although students may be in a subordinate(从属的) position, some professors treat them as equals. However, no matter how equal professors would like to be, they still are in a position of authority.

　　Professors may establish social relationships with students outside of the classroom, but in the classroom they maintain the instructor’s role. A professor may have coffee one day with students but the next day expect them to meet a deadline for the submission(提交评判) of 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 school work. Professors have several roles in relation to students; they may be friends as well as teachers. Students must realize that when a teacher’s role changes, they must appropriately adapt their behaviour and attitudes.
