In this article, the author reports on the use of classroom instructors and full-time professional teaching assistants called "course tutors" for teaching business communication to large groups at an undergraduate university. The author explains how to recruit course tutors, what course tutors do in the classroom, and the advantages and disadvantages of using them. The method is beneficial in that it reduces the grading load for business communication teachers and offers an inexpensive method for successfully teaching large group writing classes. However, teachers can lose sight of student weaknesses and not get to know their students as well as they might in smaller classes.
