This study points out that introducing and teaching semantic functions of Korean demonstratives 'i', 'ku', and 'ce' have not gained the attention of scholars and practitioners, although demonstratives are effective tools for expressing the speaker's psychological attitude towards object indication and for establishing coherence in delivering discourse. The study examined which semantic functions of Korean demonstratives, such as 'i', 'ku', and 'ce', should be incorporated as the content of teaching and how these could be taught in an effective way. As a principle of teaching, fostering learners' language awareness of the structure of semantic functions of 'i', 'ku', and 'ce' at these different strata was pursued. This made it possible to avoid giving out the glossary of each demonstrative or selectively delivering very simplified usage of them. Considering that the semantic functions of demonstratives are used in three different strata, metalingistic activities to foster learners' language awareness of these issues were suggested.
