This is one of the few times when the protective shield of impersonality at the university can be broken.
Some students are reluctant to come to office hours.
Development of a more informal, personal relationship with students can improve the atmosphere of the classroom. You may find yourself helping a student with the material for your course, with the logistics of a course that contains unfamiliar material, or with a personal problem. The best thing to do when a student comes in during your office hours is to make him or her feel welcome. Listen to your students when they come to your office. Give them your undivided attention.
