For Korean language learners, communication activities are an opportunity to actually apply their knowledge of the language to real life. The communication strategies used in this case vary according to situations and purposes. To examine the types of communication strategies used in each situation, this study analyzed the utterances of participants in speaking tests, counseling, and private conversations. It was found that communication strategies were used most frequently in private conversations, followed by counseling and speaking tests. As to purposes, communication strategies were used to resolve defects in target language resources, issues in self-utterances, and issues in the utterances of the other party of conversation. Furthermore, this study discovered that Arabic-speaking learners notably use communication strategies not only for the purpose of resolving communication issues, but also for the relationship-oriented purpose of building a social tie.
