This study aims to show the ways for the development and operation of online Korean education courses. Due to the impact of the COVID-19 and the development of information and communication technology, the conditions and environment for language education are undergoing major changes. So, we felt the need for research on online Korean language education, especially the curriculum. In this study, we would like to examine the development process and operation plan of ‘Online Korean at Yonsei Basic 1’, an online Korean language course for beginners that is installed and operated on Yonsei University’s education platform, ‘LearnUS’.
