Many practitioners in oncology receive no or little training in how to effectively communicate with patients and families who are dealing with cancer. Moreover medical teachers are not always aware of the pedagogy of teaching communication skills in a way that results in performance improvement in this area. In this paper a method of small group teaching that was used to instruct medical oncology fellows in the essentials of communication using a retreat format that lasted three days is described. The paper covers the theoretical basis for the teaching format as well as the specific components of the workshops. It describes the process of facilitation using a "learner-centered" approach using standardized patients who take on the role of cancer patients along the trajectory of the illness. It discuss the use of small group process to facilitate skills acquisition and other strategies that facilitate learning such as reflective exercises, open role play and parallel process. It concludes with a consideration of the various ways that such workshops can be evaluated.
