Strategies for designing and teaching graduate-level courses in English for special purposes (ESP) to Thai students are outlined, based on a course taught in one institution. An approach that integrates language skills (listening, speaking, reading, and writing) and stresses communicative competence is recommended, with English used as the medium of instruction. Acquisition is to be included, but primarily as support for the learning of communicative skills. Evaluation is to be based on communicative effectiveness rather than grammatical and structural accuracy. Options for task-based activities are discussed briefly, and the use of a final oral presentation, with subsequent class discussion, is described. A discussion of instructional materials looks at the advantages and disadvantages of materials produced in-house, the issue of authentic materials, and concerns in text selection.
