For the past decade, the number of English-medium lectures (EML) in South Korean universities have been steadily increasing. Although the EML policy was introduced to improve students' competitiveness in the globalized job market, its popularity among students and professors remained low. In response, universities began foreign faculty recruits; however, unfamiliarity with Korean education culture and differences related to classroom interaction often led to profound misunderstandings between foreign professors and Korean students. Drawing on existing literature, informal interviews with Clothing and Textiles students enrolled in EML, and in-class observations, this study aims to delineate main issues present in EML classroom and offer insights into how these issues can be addressed. The major problems encountered by both students and foreign faculty are multicultural nature of classroom, differences in English ability, perceived language barrier, and differences in teaching styles. Four potential solutions to these problems are outlined, and its implementations are discussed.
