This study investigates into the need for developing Korean language textbooks for self-study and analyzes the general idea, development direction and principles behind them. On the basis of real examples from Standard Korean Language Textbook (2014, HRD Korea) for EPS-TOPIK, the study aims to provide a plan for developing self-study supplementary textbooks for future Indonesian migrant workers. In contrary to textbooks used by teachers and students in Korean language classes, a textbook for self-study is centered around the student and meant to be used without a teacher. The self-study textbook proposed in this study is to provide functions of a teacher’s manual, a workbook and a workbook for EPS-TOPIK. The principles behind it are as follows: (1) to develop to be learners friendly, (2) to develop from the contrastive linguistics perspective, (3) to develop on the basis of the Multiple Intelligence Theory, (4) to present using a virtual/imaginary teacher, (5) to provide various devices that would prevent students from quitting early, (6) to diversify and systemize types of practice for improving language abilities, (7) to record and present Hangeul and key explanations about grammatical items in the students’ mother tongue. Such a textbook will be able to provide real learning opportunities to those who have been unable to learn Korean Languages due to absence of either Korean language educational institutions or teachers. By establishing both systematic links between Korean language education before and after entering Korea and a system of self-study for individual future foreign migrant workers it will be possible to further expand the propagation of Korean language.(Keimyung University)
