The major issue of Korean grammar education is the selectional matter of whether we will recognize intrinsic value of language or not. And the intrinsic value of language is the value of the knowledge about Korean Language itself. After all our selection must be subordinate to the matter of scope of Korean language education. In this paper, I reexamined the essential characteristic of Korean language education as a subject of language, and showed that the Grammar education based on Utilitarianism may lost a lot of value inherent in the knowledge about Language. And I proposed the viewpoint that we should persue various value of knowledge about Korean Language widely but should regard understanding knowledge as basic goal in Korean grammar education. I called this viewpoint as `the theory of inclusive value stress on understanding`. And then I proposed a contents system for Korean grammar education constituted with `language level` and `action level` stand on this viewpoint.
