The purpose of the study is to examine how Korean students majoring in engineering perceived EMI(English Medium Instruction) engineering courses. To this end, 50senior students completed a questionnaire. The results showed that most of the students took EMI courses in sophomore, when they started their major study, and junior year,whereas a few took them in senior year. They recognized their instructors used various teaching strategies such as speaking slower, repeating, and using more frequent words to facilitate content understanding. They suggested that the class size be limited so as to guarantee frequent feedback and interactions between instructors and students.
Regarding the course effectiveness, the study demonstrated EMI was more effective in learning engineering terminology and improving English reading comprehension.
However, they do not seem to be effective in explaining and understanding fundamental engineering concepts, which is having a negative influence on their major study. Therefore, it is suggested that EMI courses be planned and designed based on the academic year. It would be advantageous to open more EMI courses in junior year,after students finish courses in major in Korean. Major knowledge and concepts formulated from the courses could offer supportive context to EMI courses, which moves to context-embedded from context-reduced learning environment..
