The present study examined the roles and functions of literature Nonsul writing in integrated Nonsul writing, and looked for specific methods of literature Nonsul writing education for teaching integrated Nonsul writing in the field of secondary education. The reasons for introducing literature Nonsul writing into integrated Nonsul writing can be found in the excessively high level of early integrated Nonsul writing, which emphasized the close integration of the mathematical area and the language area, and the stiff demand of mathematical analysis ability in answering. That is, in early integrated Nonsul writing, the discriminability of students’ Nonsul writing was so low that assessment could not be made appropriately based on the writing, and students’ creative thinking and self-directed problem solving ability could not be assessed properly, and in order to solve these problems, literature Nonsul writing was introduced. Integrated Nonsul writing containing literature Nonsul writing is not much different from early integrated Nonsul writing in terms of form, but in terms of contents it requires the interpretation of equivocal and suggestive literary texts along with non-iterary texts and this characteristic enlarges the room for students to make subjective judgment and arbitrary interpretation. For this reason, integrated Nonsul writing containing literature Nonsul writing was considered to be more faithful to the nature of Nonsul writing that needs to solve given problems actively by integrating the contents of various curriculums. As it should be premised in literature Nonsul writing education, the necessity for switching from existing teaching methods in literature education to text study, which concentrates on reading, interpreting and criticizing literary and non-iterary texts together, was examined. Furthermore, this study looked for specific teaching methods of literature Nonsul writing, dividing the education into reading comprehension and expression. As to reading comprehension methods, we analyzed the method of analyzing topics accurately and the process of solving problems creatively based on the results of topic analysis using examples of Nonsul writing test. In addition, as to expression methods, taking note of the fact that the answer is usually composed of explanatory and demonstrative sentences, we analyzed the structure of explanatory and demonstrative sentences and, based on the results, examined how to write answers.
