This paper presents a theoretical model for representing the teaching/learning triangle and offers an agenda for research and development in this area. The theoretical framework for considering the teaching/learning triangle is based on determining the characteristics of the teacher, student, and patient/client and the dynamic realtionships between them that lead to effective teaching and learning while maintaining patient/client satisfaction with professional services rendered. A review of the literature reveals that most research studies on this topic have focused on one or more of the components of the triangle or on one or more of the relationships. The proposed research agenda focuses on determining the characteristics of effective clinical experiences for professional students from the perspectives of the teacher, learner, and the patient/client, and the relationships between each of the three participants. It is also suggested that collaborative research and development should be promoted on the teaching/learning triangle between investigators in different professions. (JD)
