A second edition of Nancy Chism’s excellent sourcebook, Peer Review of Teaching, is out. In the opinion of this editor, it is the definitive resource on peer review. Besides providing excellent summaries of relevant research and translating those findings into concrete guidelines, the book is packed with resources including checklists, review questions, and instruments relevant to the assessment of multiple aspects of teaching from course materials to classroom instruction (be it in a lab, studio, clinical setting, or online) to advising to course and teaching portfolios.
