This multiple case study explored faculty formative use of student evaluation feedback. Results were based on interviews of ten education faculty members at a midwestern research university and reviews of relevant documents. It was found that end of semester student evaluation, originally used for summative evaluation, was also used by faculty for teaching improvement purposes. Faculty cared for student evaluation feedback and used discretion in using the feedback to improve their teaching. Faculty also experienced anxiety and tensions in the context of a mandated summative evaluation. Variations were found in faculty use of evaluation feedback, as a result of difference in background and experience.
