Since South Korea started to operate MOOC service in 2015, the number of courses and registered students have greately increased every year. However, like the global MOOC, K-MOOC has also experienced problems in quality control in learning and completion rates, etc. As the various discussions about K-MOOC spread from the viewpoint of opportunity and challenges, researches related to academic papers have been increasing rapidly in recent years. At this point, this study aims to examine the research trends by integrating the academic researches published in Korea, and to analyze the research key words and contents highted in those researches. For the purpose of this study, a text-mining tool was selected to analyze the major research keywords and themes presented in the 83 published research journal articles. The findings revealed in the MOOCs literature of Korea can be summarized as follows. First, based on the result of frequency in research keywods, MOOC related research in Korea shows four themes: (a) higher education, including university and life-long education, (b) new model for online learning, e-learning and flipped learning, (c) analysis of characteristics in learning and learners(motivation, intention, interaction, safisfaction, etc). Second, the result of network analysis shows that MOOCrelated academic papers generally focused on analyzing the phenomenon appearing in the learning model of MOOC, rather than to capture the characteristics of K-MOOC itself. In addition, there are many practice-centered instrutional design studies that are applied to MOOCs in university(colledge) and adult education. Especially, flipped learning showed strong central degree in those papers. Based on these results, which mapped patterns and features of MOOC-related researches published in Korea, the present state of MOOC implementation and academic research is demonstrated, concluding with some implcations for future researach directions.
