While ‘textbook compilation’ starts from learners’ demands and needs, a ‘teaching method’ is to approach learners’ demands and needs and is an important factor to determine the orientation of textbook. Considering that the transition in foreign language teaching methods influences textbook development and change, this study is, therefore, intended to figure out a correlation between teaching methods and textbooks. For achieving this study purpose, this study analyzes Korean textbooks and examines the effect of foreign language teaching methods on actual Korean textbook compilation. It is thought that although figuring out a correlation between teaching methods and textbooks would influence the orientation of textbook development, fundamentally, it is a definitely necessary process to suggest the direction of Korean language education and to seek a proper methodology for the future. In order to find out a correlation between teaching methods and textbooks, this study plans to analyze nearly 100 textbooks of each time period and to investigate textbook contents, compilation intentions of authors, and teaching methods that took center stage in those times, for an in-depth analysis. It is anticipated that this would help in grasping a diachronic and systematic flow of textbooks of the past, of the present and of the future. For a more minute performance of the study purpose and contents, this study classifies a discussion on textbooks and teaching methods into two aspects, based on different time periods and is especially focused on a discussion from the conventional teaching method to the direct method.
