A model of structural linguistic analysis as well as a teaching tool, this text gives the student a comprehensive grasp of the essentials of modern Korean in 25 lessons, with 5 review lessons, leading to advanced levels of proficiency. It has been designed for adult students working either in classes or by themselves, with the assistance of native speakers or tape recordings. Each lesson contains basic sentences, grammar notes with additional examples, exercises, comprehension practice, and conversation guides. Of particular value is the systematic presentation of grammatical structures, with a detailed cross-index integrated into the Korean-English vocabulary that accompanies the English-Korean vocabulary at the end of the book. The pronunciation is introduced in carefully planned drills that are grouped together at the beginning of the book. The course follows the overall pedagogical methods that have come to be known as the Yale audio-lingual approach.Mr. Martin is chariman of the Department of Linguistics at Yale University, and Mrs. Lee is assistant professor of Korean at the University of Hawaii.
