Choi, Ji-hyun In this study, I examined about meaning and its practical demands of the cyber language community that is formed in cyberspace in Korean Language Education. Cyber language community is base, at the same time, substance of cyber community which have computer and network by interface of communication. Also, it is community which makes new experience area formed thereinto with communication between human and interface by important characteristic. The reason that I observed in cyber language community mainly as follows; First, a subject has new identity and activity mode in cyber language community. It means that interface of community, like computer and network, does not stay in level mediating communication simply functionally. Also, acceptance of cyber language community can make us suppose a relevant counter-discourse against the dominant discourses that transmit simple message to mass for one side through limited channel as broadcast- ing in television. Because language in computer mediated communication fulfills its condition that counter-discourse must possess, as much as to say a new rules of language use, possibility as regional-private discourse, and the overall influence of discourse effects. Conclusively, I proposed that Korean language education must prepare a educational considerations about cyber language community. And in these considerations following things need to be included. 1) comprehension about the mode of the language in computer mediated communication and the norm in the formation, 2) new awareness for learning and memory that is attached importance to language and human relation, 3) approval and effort for acceptance of multiplex language environment and multilingualism, 4) re-thesis of status of Korean language education, as cyber education 【key words】 Cyber Language Community, Korean Language Education, Computer Mediated Communication(CMC), Language in Computer Mediated Communication, Counter-Discourse
