A course called "The Study of Teaching," designed to develop a theory on teaching and to explore the philosophy of teaching, is described. Five teacher education professors and five graduate students participated. Although one professor acted as instructor, the fifteen hour course was relatively unstructured and based on collegial discussion within the group. Discussion focused upon the contention that teaching can be investigated and described as being the act of creating, communicating, decision making, valuing, and as an aesthetic experience. A participant-observer of the course reports the progress of the group, discussions on each of the five foci central to the course, and conclusions made as well as further questions that were raised by the group. Appended is an abstract of a paper generated by the course on the process of theory building and its influence on teacher education faculty. Materials used in conjunction with the course are listed.
