Existing literature on pronunciation instruction in English as a second language is reviewed, revealing that significant attention to the improvement of American English pronunciation among foreign students has been lacking. For the teacher's benefit, an analysis of basic phonetics is presented, laying a foundation for understanding pronunciation problems of foreigners. A model of nine lessons for teaching American phonemes is developed in detail, using one example (th), but applicable to all others. A multi-approach technique is used (audio-lingual, syntactic, contrastive analysis, articulatory, theatrical, visual aids), as well as useful games and special devices. The study emphasizes the great need for, and advantages of, increased attention to pronunciation improvement. (Author)
