Hi Judy, You ask a good question that has a number of different answers to it. Many instructors like to be called by their first name. I have always preferred to call my instructors by their last names and I want my students to address me by my last name as well. I think this sets the tone for the instructor student relationship. Having them call you Mrs. G is a great way to go because the use of a title is there but the shortening of your name to a letter creates a base for the development of rapport on a personal level with your students. I wish you much teaching success, Mrs. G! Gary
