The purpose of this study was to make a comparative analysis of communication strategies that Korean teachers and native speaker English teachers use. Toward this end, four forty-minute classes taught by four respective teachers (two Korean teachers and two native speaker English teachers) at an English Experience Center were transcribed. Analysis was then made of the use of communication strategies by the teachers within the framework of D？rnyei and Scott (1997). Results showed that the two groups of teachers had some differences in the use of communication strategies: The Korean teachers often used mime, all-purpose words, and code-switching while their native speaker counterparts frequently resorted to mime and repetition. Differences were also observed between the teachers regardless of their language backgrounds. It was observed that the differences could be partially attributable to the learning and teaching backgrounds of the teachers.
