The research on reading existing masterpieces was initiated with a sense of problem about the division and disconnection of text, thereby promoting innovation in Korean language classes. However, the field is still in a dilemma over how to link the textbook with the whole work. Therefore, this researcher proposes 'Whole Work Reading Class using textbooks' to find alternatives in the dichotomy of romantic Korean language education, which requires only textbook-oriented Korean language education and full-length works to be dealt with. The study was conducted on fourth graders of Cheongju ‘S Elementary School’ for two years. This researcher and the academic community designed the curriculum and described the one-performance course in executing the course through the implementation of the class. The purpose of this course was to gain insight into the educational meaning of the course through the textbook developed. This ensures teachers' autonomy by linking and converging the curriculum, textbooks and masterpieces. And it is an attempt by a teacher to grow up as a developer and expert in the curriculum, and at the same time, to focus on the individual growth of students. Therefore, the whole work reading class through the textbook took advantage of the textbook and presented intact text, and all teachers sought sustainable classes. In addition, it was intended to present a new model of a virtuous cycle of curriculum, classes, and evaluation by considering the suitability of the evaluation.
