A study examined the difference and effects of sex and sex-role on course evaluations of journalism/mass communication instructors at a midwestern university that had recently consolidated its school of communication and its journalism/mass communication courses. Subjects, students in 18 communication or journalism/mass communication classes taught by 9 full-time instructors, completed a questionnaire. Both standardized evaluations and the indexes of culturally desirable gender traits showed high ranking for women instructors. Instructors were not matched for variables such as experience. Interaction effects between same-sex instructors and students were not found; however 2-way interactions between instructor sex and type of course were observed. Further research in gender-based evaluation is called for. (Contains 41 references and 7 tables of data.) (Author/RS)
