This is the first in a four-volume experimental series of instructional materials on English for Vietnamese speakers. This volume deals specifically with pronunciation. The lessons are based on a systematic comparison between the Vietnamese and English sound systems, including intonation and stress patterns; the theoretical basis for the comparison is the theory of Kenneth L. Pike. A specific method for presenting sounds to the students is outlined, stressing the fact that the teaching of pronunciation should be systematic. Learning proper pronunciation will improve other skills, such as reading and writing. There are thirty-two lessons, each containing a teacher's guide for presenting and teaching the material and a student's guide for pronunciation practice. (CLK)
