The purpose of this study is to provide an analysis of Korean language teachers'' methods for teaching vocabulary. For this purpose, aspects of repetition in classroom conversation were examined using classroom conversation structure analysis methodology. The results show that Korean language teachers use key pedagogical themes as conversation topics and through a process of continual repetition of these themes enable the students to continually encounter the target words within the conversation; thereby facilitating the learning of vocabulary. The analysis also indicated that Korean language teachers find ways to relate target words to their students’ experiences and in this way reinforce them through repetition. In addition, this analysis suggests that Korean language teachers employ a dramatization frame in order to repeat words. These dramatization frames can be used to encourage the students'' awareness of the target words. Based on the results of this study, it is possible to postulate that the setting of convergent topics is required to control words, thereby enabling their efficient repetition.
