Student knowledgeability, student sex, class size, and class level: Their interactions and influences on student ratings of instruction

Student knowledgeability, class size, and class level were found to significantly influence students' ratings of instruction. In general, the more knowledgeable the student in an area, the higher his ratings of courses and instructors in that area. Also, large courses and advanced courses were most highly rated by students. The effect of student sex on student ratings of instruction varied as a function of the particular aspect of instruction being evaluated. Significant interactions among the four main effects were also found across the judgmental dimensions students utilized in evaluating instruction, as assessed by factor analysis. Student knowledgeability and class size were found to be the main predictors of student ratings on these dimensions.
