This study examines the relationship between the communication anxiety of Korean language learners and their use of applications in Korean language learning. Since the smartphone market started in 2010, it has developed applications for Korean language education and, today, various Korean language learning applications are available. The purpose of this study is to examine how the preferences of Korean language learners influence their intention to use Korean language learning applications. Accordingly, the study involved measuring the communication anxiety and innovativeness of Korean language learners and examining whether they use applications to learn Korean and how frequently they use such applications. Results revealed that 80% of the respondents use Korean language education applications. On examining the relationship between learners’ characteristics and the learning method, the study reveals that technological innovativeness of learners is associated with their tendency to study Korean using the Internet or mobile applications. The current study, which examines the relationship between learners’ tendencies and use of educational applications in Korean language learning, is significant in that it reveals how the development of diverse learning methods not only diversifies the methods of learning but also facilitates the design of customized learning methods suited to individual learners.
