Lee, Seong - Young The aim of korean subject is to bring up students’ textual abilities. So the main task in compiling korean textbook is to select proper material texts. The purpose of this paper is to scrutinize requisites for material texts of korean subject. First of all, material texts of korean subject should contribute to accomplish instructional objects. They call it as inclination to object. Material texts should be suit to educational contents and developmental properties of students. Second, material texts of korean subject should have inclination to value which encourages mental growth and which transmits cultural heritages. Finally, material texts of korean subject should have inclination to harmony which contains balance and hierarchy. Unlike inclination to object and inclination to value which are requisites in dimension of individual text, inclination to harmony is requisite in dimension of inter-text. We can use these requisites in various times when we compile textbooks of korean subject, when we select one among them, and when we select various reading materials other than textbooks.
