Based on the discussion of the anthropological theory of didactics(ATD), this study aims to construct a praxeology of ‘scholarly knowledge’ and analyze the appropriateness of educational contents of Korean passive expression designed as ‘knowledge to be taught’ through analysis of Korean language texts by dividing them into theoretical and practical blocks. To that end, the content of the education presented in the textbooks were analyzed focusing on ‘Is the theory of scholarly knowledge transposed into knowledge to be taught without fragility?’ and ‘Are passive expressions learning successful when all given tasks are performed?’ by dividing into aspects of form, meaning and use. The inductive results delivered in specific statements are as follows. ① The knowledge of form is limited to passive which is produced by suffix ‘-i/hi/ri/gi’ and ‘-eojida’, ② the knowledge of meaning is presented in a mixture of typical passive and non-typical passive without distinction, and ③ the knowledge of use is limited to presenting basic uses in some textbooks.
