The 40 lessons in these two volumes and the accompanying tape recordings are designed to teach standard spoken Thai to Foreign Service Officers and other American Government personnel. After completing the "Programed Introduction to Thai Phonology," the student should be able to read the phonemic transcription in which all Thai material is presented. Each lesson is composed of: a Basic Dialog (in transcription and English translation), Notes on the Dialog (information about Thai culture), Grammar Notes (nontechnical explanations to be studied outside of class), Drills (practice on particular grammatical patterns), Exercises (opportunities for the student to use Thai to communicate in a realistic situation), and a Vocabulary list. A Comprehensive Glossary at the end of Volume 1 contains the 1,400 Thai words presented in that volume. Volume 2 is made up of lessons 21 through 40. A third volume is planned. The authors have made use of R. B. Noss'"Thai Reference Grammar," ED 010 347. The tape recordings, which are an integral part of the course, are available from the Sales Branch, National Audiovisual Center (GSA), Washington, D.C. 20409. (JD)
