This guide identifies many specific ways that instructors can improve their teaching to foster greater student learning. The author reviews the current approaches to assessing teaching and describes their inadequacies. The author then presents a new model of assessing teaching that builds upon a broader base of evidence and sources of support. She describes how this new model leads to self-assessment rubrics and how to apply these rubrics. Case studies of completed critical reflection rubrics assist instructors in understanding how they can use these rubrics in different ways and to explore the richness of the data. The case studies come from a variety of disciplines, including performing/visual arts and the hard sciences.
