Some Methodological Considerations in the Use of Factor Analysis to Determine Dimensions Underlying Student Ratings of Courses and Instructors.
Albino, Judith E.; Liberty, Paul G.
The data presented in this report call attention to inappropriate use of the Eigenroot criterion in factor work, a practice which has probably grown out of a theoretical focus on determining basic laws of behavior, rather than a practical emphasis on providing information that will be useful to college instructors and administrators. When researchers have sought only the general, broad dimensions that occur in Course-Instructor Survey (CIS) ratings, instructors and administrators have concluded that only these larger factors are needed in describing the evaluation of courses and instructors. In reality, however, administrative decision making and the provision of comprehensive feedback to instructors may demand that more specific factors be identified. In such cases, the proportion of variance criterion for stopping factoring may reveal information which would be lost were the Eigenroot criterion applied without regard to variance extracted. The question of when to stop factoring, then, seems to be best answered in terms of whether general laws of behavior are sought, or basic dimensions for specific practical applications are desired.
