A term-project assignment for a course in phonetics for prospective teachers of English as a Second Language (ESL) is described. The project involves six steps: (1) identification of a specific pronunciation problem for study; (2) analysis of the problem; (3) development of a self-instructional program; (4) recording the program on audio-tape; (5) evaluation of the taped program; and (6) regular progress checks with the instructor. The tapes are kept by the department for use with specific pronunciation problems of individual students. In addition to increasing the department library, the projects provide the students with experience in laboratory exercises and construction of remedial exercises. A transcript of a term-project on "can" and "can't" is included. (AMH)
