Student evaluations of instruction were factor analyzed to determine if students in the colleges of education, business, and engineering at Michigan State University varied in their perception of factors contributing to good instruction. The data base for the study consisted of evaluation forms that were processed during fall term, 1976, with a universe of 550 classes throughout the university. To produce stable results from factor analysis, approximately equal-size samples of 200 evaluations each were selected from the three colleges. Factor analyses were run on each individual college and on the combined sample containing all three colleges. In addition, separate analyses were run using the student, the class mean, and the student response removing the class mean as units of analysis. The results indicated that the variability in different factors differed considerably across colleges which may suggest that the evaluations require interpretations suitable to each college or that a unique form be developed for separate colleges. Additional research was supposed to obtain a large enough sample from each of the departments within the business school to recognize differences between departments and develop appropriate weighting schemes for each.
