A Study on Organization and Content of Teacher's Guidebookfor Teaching Korean Languagefocus on Onomatopoeia and MimectChu, Kuyng-heeI reviewed organization and content of teacher's guidebook for teaching Korean language focusing on onomatopoeia and mimect in this article. Teaching methods have little meaning however peculiar and fresh they are if they are not efficient to implementation of curriculum.In this view point, didactical transposition should apply to curriculum, content, teaching method, activity and stragity etc. In other words, scholarly knowledge can be said to be converse of knowledge having educational purpose. as teaching methods not founded on didactical knowledge emphasize only techniques, they induce to continue to deal with fragmentary knowledge of onomatopoeia and mimect and make the improper teaching method such as topaze effect, Jordan effect, metacognitive shift and the improper use of analogy, etc applied. Therefore, we should teach about them founding on knowledge about usage of onomatopoeia and mimect to get out of these teaching methods. We should explain between paradigmatic or syntagmatic relations, not with single vocabulary to explain various functions and usages of onomatopoeia and mimect.
