Is Class Size a Bias to Student Evaluations of Faculty? A Review
Student evaluations of faculty have been widely used for measuring teaching effectiveness. However, many faculty members complain that such evaluations are biased by many extraneous variables and, consequently, do not reflect real differences in teaching effectiveness. Of the numerous extraneous variables that may constitute biases to the ratings, class size has been particularly controversial. Based on construct validation approach, this review of existing studies of the relationship between class size and student ratings indicates that student ratings are reasonably valid and relatively uncontaminated by class-size effect.
