Teaching in English has been an issue among faculty in Taiwan. Universities encourage faculty to conduct courses in English, however, faculty found it difficult not only to prepare the materials but also to communicate with students in different English level. To develop the skills of Engish-Medium Instruction (EMI), we invited four experienced professors in EMI field to share their experience, discuss issues frequestly occured and demonstrate their teaching skills in class. The teaching demonstration will include teaching the class mixed with international and local students and case teaching in English. Through this workshop, we hope to develop faculty's confidence, enthusiasm and efficiency of conducting EMI, and for those who have done EMI for long time, to share and pass experience to the faculty who are new to EMI.
