The purpose of this study was to determine what relationships exist between course and instructor evaluations and student/instructor preferences regarding classroom instructions. The specific null hypothesis explored was: The congruencies on ratings of the personal preferences of students and the personal preferences of instructors will not be reflected in the ratings of the course and instructor by the student. The scales used for the present study, the Personal Preference Scale (PPS) and the Instructor Preference Scale (IPS), were developed from George Stern's Activity Index (AI) and College Characteristics Index (CCI). Subjects were undergraduates in nine colleges or departments at the University of Delaware. Results seem to indicate that the student ratings on course and instructor evaluations are affected by how much the student and instructor values are similar toward a classroom environment.
