The purpose of this study is to review the issues related to parallel corpus and previous studies using parallel corpus, and also to examine how to use parallel corpus in the studies of Korean language education. This study starts by summing up the concept, types, and the structure of parallel corpus, and examining problems in construction and use. Next, we review the current trends of language research and language education research using parallel corpus, and then examine the trends of studies related to Korean language education, especially focusing on language contrastive studies. Finally, we would like to conclude what to consider when trying to use parallel corpus in studies of Korean language education, and the direction of the Korean language education research using parallel corpus in the future.
