This study aims to identify the patterns of vocabulary composition changes by conducting a quantitative comparative analysis of the vocabulary included in Sejong Korean (2011-2013) and Sejong Korean (2022), a standard textbook series for Korean language education. The research methodology involved a comprehensive survey of index vocabulary from both textbook versions, followed by systematic comparative analysis based on vocabulary volume, part-of-speech distribution, vocabulary type composition, and grade-level consistency. The results revealed that the revised edition showed a significant decrease in total vocabulary. The proportion of Sino-Korean words decreased while native Korean words and loanwords increased. Content-wise, traditional culture-related vocabulary decreased while modern leisure activity-related vocabulary increased, with a notable shift from vocabulary focused on foreign culture to vocabulary related to tourist attractions in Seoul. These changes are analyzed as results of Sejong Institute’s curriculum diversification, its pursuit of universal Korean language education goals, and reflection of contemporary demands. This research provides important implications for future Korean language educational vocabulary selection and textbook development direction.
