Evidence of a Single Second-Order Factor in Student Ratings of Teaching Effectiveness

In student-evaluation research, there has been considerable debate on the number of higher order factors in student ratings of university teaching. Using a distance learning program as the context for research, the study described in this article applied structural equation modeling to investigate the 2nd-order factor structure in student ratings of teaching effectiveness. An a priori model was hypothesized, which consisted of four 1st-order factors and one 2nd-order factor. Data were collected from 2,021 distance students using a multifactor questionnaire. In contrast to all past studies, the presence of a single 2nd-order factor in student ratings was empirically demonstrated through hierarchical confirmatory factor analysis. Implications for future research on the higher order factor structure in student ratings of conventional on-campus courses are also discussed.
