This study examines expressional styles and plans for the education of Korean language in computer chatting rooms, which are relevant to hypertext, as a part of preparing the contents and methods of hypertext expression education\n\n First, because of the 'anonymity' of computer chatting rooms, people can expression their feelings without concealing. On the other hand, anonymity causes flaming and undermines linguistic morality. Conversations in computer chatting rooms occur through direct feedback using 'interaction' Because many meetings and conversations in computer chatting rooms are improvised, they are more impersonal than sincere, and politeness and rules necessary for conversation are often ignored Language in chatting rooms is exchanged by texts, but they contain oral elements, which are expressed through the mouth, as well as non-oral elements That is, the language. is mixed with oral words and textual words.\n\n Telecommunication language is used based on strategies for preserving efficiency, those for preserving expressivity, and psychological factors. Although some view it negatively saying that it destroys linguistic norms, its positive side of creative utilization of texts is not negligible, The reason that such telecommunication language is perceived negatively is its influence on everyday language. Concerning the influence, further research is required.\n\n Research related to the education of expression in computer chatting rooms is mostly focused on telecommunication language. As the present researcher investigated, in addition, contents in Writing and Korean Language Life in the 7th Education Curricula also deal mainly with the destruction of linguistic norms by telecommunication language and problems in linguistic morality.\n\n Thus, the researcher proposes plans for the education of Korean Language related to expressions in computer chatting rooms as follows. ① It is necessary to understand telecommunication language positively, regarding it as a social dialect. ② In a sense, abbreviations, emoticons (emotion icons) and symbolic words are language creation, which are necessary for efficient conversations in communication. ③ Except the examples presented in ②, telecommunication language should not be transferred to everyday language, and for this students must learn grammar intensively and have an ability to distinguish virtual worlds from the real world ④ Students must be given not only theoretic education on the characteristics of oral and textual words rot also one related to conversational expressions in computer chatting rooms in 'Speech' and 'Narration' classes.
