A study was done of high school students' perceptions of gender bias on classroom management. Using an 8-item survey instrument developed from ideas presented by several classroom management experts and teachers, 198 female and 156 male high school students were surveyed. Students rated two teachers, identified only by gender, on each survey item. The students chose teachers who they felt fit the instrument's description of having a well-disciplined class. The results indicate that female teachers were more likely to be chosen as effective disciplinarians by female students, and male teachers were more likely to be chosen by male students. Female teachers were rated higher than were male teachers on four survey items. Male instructors were rated higher than female teachers on only one item. Female instructors were rated equal to or higher than male instructors on seven survey items. Also, the number of female teachers chosen as effective disciplinarians increased at each grade level. The only negative for female teachers discovered by this study was the belief that women are more likely to become frustrated than men. Included are copies of a letter to teachers, the survey instrument, and 26 references. (JB)
