This article presents three case studies that explore a very popular trend in art museum adult education in the last decade--partnerships with medical schools to offer critical professional development in visual observation. Each case study describes a critical perspective in the development and implementation of this programming trend: that of the art museum educator, the medical school faculty, and the collaborative vision of the museum and medical school together. The article concludes with a brief explanation of evaluation and assessment research to date on the impact of these programs. (Contains 15 notes.)
