The purpose of this study is to identify aspects of speaking strategies that can be seen in dialogue of Korean language learners during the process of learning Korean from beginning to advanced levels. According to the research result, learners continuously used the repeating strategy from beginning to advanced levels, and it was identified that learners used a lot of borrowing and asking strategies in the beginning level, asking and stalling strategies in the intermediate level, and paraphrasing and revising strategies in the advanced level. The borrowing strategy that learners frequently used in the beginning level was from learning a foreign language that learners previously learned, which in this case refers to English speaking, but it was identified that communication in Korean is possible as the frequency of using English significantly decreased from intermediate level. This study has significance as a case study that identified how speaking strategies of Korean language learners change within a certain period of time of learning the Korean language.
