The internationalization of higher education has been an important issue both in policy making and educational practice. Using English as a medium of instruction (EMI) has been adopted by many non- English speaking countries, including Taiwan, as a resolution to increase enrollment rate and cultivate students’ competitiveness in recent years. This paper reviews the literature focusing on the current practice and difficulties of implementing EMI courses in non-English speaking countries, and then follows by introducing the EMI courses implemented at Gent University in Belgium as an example; the findings are based on the researcher’s visiting experiences and dialogues with course lecturers and students: 1. The implementation of EMI courses will promote the internationalization of school and provide students with multiple learning choices; 2. The implementation of EMI courses should take in account of students’ language skills and their prior knowledge as well as experiences; 3.The implementation of EMI courses shall adapt the teaching approaches to students’ learning difficulties and provide support for learning.
