A Case Study on Korean Language Classes Using Generative AI: focus on Vietnamese learners

This study explored how effectively and critically learners of Korean as a foreign language utilize generative artificial intelligence (ChatGPT) as an auxiliary tool for learning while maintaining learner autonomy. To this end, generative AI, particularly ChatGPT, was used as learning tool in a major course titled Metaverse and AI Korean; The course, designed and implemented for 35 Vietnamese learners, integrated metaverse platforms and AI technology into Korean language instruction. The curriculum consisted of three core tasks: writing self-introductions, translating texts, and composing argumentative essays. Each activity was conducted in two phases—self-directed production and AI-assisted output. A post-course survey examined learners’ satisfaction, preferences, perceived learning effectiveness, and fact-checking practices. The results showed that ChatGPT was pedagogically beneficial. And the students engaged critically with AI-generated content by analyzing and revising it, rather than accepting it at face value—an approach that fostered the development of higher-order thinking skills. These findings suggest the importance of explicit instruction in prompt engineering and ethical considerations when employing generative AI in Korean language education.
