The goal of this study is to understand the needs of international undergraduate learners and students from multicultural background, and to develop and evaluate a learner-centered Korean language education program based on the method of the living lab. The living lab activity implemented with members of a university Korean language and literature club, who were required to conduct a need analysis of international learners and, divided into four teams, create a living lab program. The goal of the four teams was 1) to develop Korean language material which included characteristics of the regional area, 2) foster cultural understanding through the development of a multicultural narrative collection, 3) create videos dealing with idiomatic expressions for advanced Korean language learners, and 4) run a counseling community for peers. Analysis and evaluation was conducted on two groups, and demonstrated that participants engaged in active and spontaneous learning. This study contributes to the literature in Korean language education by demonstrating a learner-centered approach based on the living lab method. Considerations on the program expansion and sustainability remain as future task.
