The purpose of this study is to analyze the Korean textbook Learn Korean on Your Own 1~4 to understand the North Korean approach to teaching Korean as a foreign language. The textbook has been written for English speaking learners. In summary, this text is a helpful grammar textbook and reference for adult students using a self-study methodology. It explains Korean grammatical items in a detailed and systematic manner, providing numerous examples and tables. To illustrate the different Korean speech levels, it also helpfully uses pictures and arrows to graphically represent the correct speech level. However, it has several weaknesses that distract from its effectiveness. It makes unnecessary use of technical terms. For a self-study grammar textbook, easy-to-understand terms would be preferable. And it uses a romanized guide to pronunciation which is confusing. With regard to vocabulary, it is arranged in order of sino-Korean words, native Korean words, and loan words. And it uses propaganda-like example sentences and written style. A grammar textbook should employ a contrastive analysis with the student's native language, use easy-to-understand terminology and provide helpful practice activities.
