These textbooks are the ninth and tenth volumes in a five-level series developed collaboratively by leading classroom teachers and linguists of Korean. All series' volumes have been developed in accordance with performance-based principles and methodology--contextualization, learner-centeredness, use of authentic materials, function/task-orientedness, balance between skill getting and skill using, and integration of speaking, listening, reading, writing, and culture. Grammar points are systematically introduced with simple but adequate explanations and abundant examples, exercises, and drills. Each lesson of this volume consists of pre-reading activities, one or two main reading texts, new words, useful expressions, exercises, comprehension questions, related reading, discussion and composition, and English translation of the reading texts. Integrated Korean is a project of the Korean Language Education and Research Center (Klear) with the support of the Korea Foundation. In addition to the five-level textbooks and workbooks, other volumes include Korean Reader for Chinese Characters and Korean Composition. Selected Readings in Korean, Readings in Modern Korean Literature, Korean Language in Culture and Society. A Dictionary of Korean Grammar and Usage and instructor's manuals are forthcoming.Cho, Sungdai is the author of 'Integrated Korean High Advanced 1', published 2005 under ISBN 9780824825690 and ISBN 0824825691.
