This is one of a series of self-teaching textbooks initially prepared for the Armed Forces and now offered to the public. The emphasis is on speaking rather than on reading or writing. Book 1 is divided into two main sections, each consisting of five lessons and a review section. Each lesson deals with some aspect of daily life, and each is divided into several sections: word study, basic sentences, pronunciation practice, grammar, conversational situations, and a "finder list," containing the vocabulary introduced in the unit. Book 2 is divided into three main sections, each containing five lessons and a review section. There is more emphasis on grammar in Book 2, but the format is similar to that of Book 1. Each unit is designed to be used with a native speaker of Thai or to be accompanied by recordings. The appendix contains supplementary vocabulary, and a Thai-English, English-Thai glossary. (CLK)
