A 21-item questionnaire was used to examine the attitudes of 120 student teachers before and after their field experiences. Topics covered included teaching methods, teacher-student relationships, and lesson preparation. Mean difference scores were examined from the viewpoint of student teachers' sex, type of class taught (elementary, secondary, or special), and subject area. When the scores were compared for sex, it was apparent that men tended to value authoritarianism more after student teaching, while women's attitudes tended to remain unchanged or to be reduced toward favoring authoritarianism. Both men's and women's reliance on lesson preparation reduced during the student teaching. The type of class taught did not seem to influence changes in the student teachers' values. Due to the relatively small number of student teachers in each subject area, specific differences across subject groups were not interpreted. The investigation showed that student teachers valued traditional educational principles and practices less after the student teaching experience. (FG)
