This research aimed to understand the environment and needs of overseas Korean language learners and to seek a solution through the use of media. To do this, we divided learners into Eastern and Western culture areas and made a comparative study. As learners who grew up in Eastern and Western culture areas have different background knowledge and learning needs, it is very important for teachers running classes in each area to understand the differences between the culture areas of the learners. This research used surveys and media production assignments to investigate the needs and characteristics of undergraduate Korean language majors at overseas universities and to seek effective teaching methods for each location. Through this we obtained the following results. First, we analysed what overseas Korean language learners need in a learning environment, and what they think about using media for study. Through the analysis of needs, we found that using media is not only familiar to overseas Korean language learners already but also useful as a method of learning. In the second place, we checked how the mother-culture that learners acquired as they grew up in each culture area influences their Korean speaking assignments. We had the learners conduct a speaking task and then submit it in video form. From analysing these assignments we reached the following three conclusions. First, Eastern and Western learners showed different tendencies in choosing subjects and creating the content. We found that most Eastern learners made content with similar topics, while Western learners were interested in more varied topics. Second, Eastern and Western learners showed a difference in the way they developed the content. Eastern learners preferred a format that develops the story depending on its situational context, while Western learners preferred conveying a story that pivoted on factual information. Third, there was difference of accuracy and fluency in the communication situation. Eastern learners tried to speak accurately in communicating through the second language, while Western learners tried to speak fluently with an emphasis on interacton.
