Convergent and Discriminant Validation of Student Ratings of College Instructors.
Hillery, Joseph M.; Yukl, Gary A.
This paper reports the results of a validation study of data obtained from a teacher rating survey conducted by the University of Akron Student Council during the Fall 1969. The rating questionnaire consisted of 14 times: two items measured the student's overall evaluation of his instructor; 5 items measured specific performance dimensions such as stimulation, communication, consideration, evaluation, and workload, and each of these dimensions was measured by two methods: (1) asking the student to compare his instructor with others he had known, and (2) requiring the student to make an absolute evaluation of the instructor on a graphic rating scale. The last two items obtained information on the student's class standing, and his cumulative GPA. Information was also obtained on the size of each class, the average grade given in each course, and the instructor's rank. The data analysis consisted of the multitrait, multimethod approach to convergent and discriminant validation, first proposed by Campbell and Fiske in 1959. The results indicated that the performance dimensions showed fairly high reliability and convergent validity. However, the discriminant validity was not high enough to conclude that independent dimensions of instructor performance were being accurately measured. (AF)
