The team approach to developing and implementing English for special purposes (ESP) programs is described. Team teaching is defined as several teachers strictly following the same program even though they teach different groups of students. In the team teaching situation, it is essential that the course coordinator and teachers confer with each other frequently for extended periods of time. It usually requires an average of ten hours of preparatory work to generate one hour of class work in an ESP program. It is asserted that the team approach produces higher quality course curricula and teaching materials. Four basic problems associated with the team approach are examined. These are: (1) the difficulty of integrating course objectives, (2) inflated expectations about what can be accomplished, (3) underestimation of the amount of time needed to produce teaching materials of high quality, and (4) over emphasis on course completion regardless of the real progress made by the majority of the students. Program objectives and syllabi are appended. (RW)
