The purpose of this study is to develop Korean vocabulary learning contents using social network services. Prior to the material production, Korean language learners were asked to respond to descriptive questions to investigate their perceptions and needs for education using SNS. After that, actual vocabulary learning materials were produced. Based on the learning materials produced after developing vocabulary learning contents according to the results of the first survey, the second survey was conducted. Finally, the study was conducted using the method of implementation research that reflects the results of the response. All of this data was provided in the form of posts on Instagram according to learner needs, and all participants who responded to the questionnaire after production indicated that they were satisfied with the content developed in this study and that the learning content helped them to learn Korean. In addition, participants stated that they were interested in learning Korean by using the contents developed in this study and that they wanted to continue vocabulary learning in this manner. This study is significant in that it developed actual learning contents, shared them with learners, listened to their opinions, and completed the process of modifying the developed contents.
