Written comments on student evaluations often seem idiosyncratic, lacking the power of numerical statistical data. These statements, however, may sometimes reveal intellectual challenges common to novice learners in our disciplines. Instructors can use these insights as part of a scholarly approach to teaching, making meaningful adjustments to future classes and informing curricular choices in productive ways. In this article we examine common student complaints in three particular situations: quantitative classes, writing-intensive courses, and classes taught using student-active formats. We discuss implications of these comments for faculty as they seek to promote students' intellectual development.
