This paper examined the effects of online English-medium instruction (EMI) on high school students’ performing English face threatening speech acts, by assessing indirect expressions and token agreement (agreement plus but). Participants completed an English placement test and English pretest and posttest through a Google survey. English proficiency, required for study participation was measured using the English placement test. An English pretest and posttest measured English pragmatic performance. The students were given approximately four weeks to complete eight online lectures. The experimental group completed eight online lectures which taught five face threatening speech acts, based on formal situations in the United States. The control group completed eight online lectures about worldwide cultures. The experimental group showed a significant improvement in the English posttest compared with the control group, based on improvements observed in the use of indirect expressions and token agreement. A difference between groups using indirect expressions was observed in an unfamiliar person scenario but not in a familiar person scenario.

This study explores the effects of teacher feedback on engineering students’ perceptions of learning a business subject and English development in the context of English-medium instruction (EMI). Using a mixed method, it examines specific contributions of teachers’ extensive feedback to the students’ emerging perceptions of interdisciplinary education and EMI. The quantitative section includes questionnaire responses of two groups of students enrolled in four sections of an entrepreneurship course: the control group (CG) in which the students received limited feedback in the lecture-style EMI (n=137) and the experimental group (EG) of extensive corrective feedback (n=133). These results are cross-examined by a semi-structured focus group interview with four respondents. The analysis shows that the university seniors’ mean satisfaction score with EMI, despite staying around the mid-point, was higher than that of the others, and significantly more so than the freshmen group. Notably, EG students appreciated EMI more than CG students. Subsequent findings establish that extensive feedback correlates with the increased positivity towards learning entrepreneurship and, more importantly, English development. This study thus proposes English programs for specific purposes and a support system including an EMI-specialized teaching methodology.

While the number of English-medium instruction (EMI) courses has increased in many EFL universities, relatively little attention has been paid to students who encounter language difficulties in EMI courses. In order to develop language support programs for Korean undergraduate students in foreign professors’ EMI courses, this study collected and analyzed the syllabi of target courses to identify what English language skills are necessary for these courses. Findings suggest that priority should be given to teaching research-oriented English skills such as academic writing skills, with particular emphasis on how to use primary and secondary sources. Furthermore,students need to acquire speaking skills based on an understanding of readings or lectures so as to participate in discussions and to make presentations. Given the greater number of opportunities to interact with foreign professors, it is necessary as well to teach the appropriate mode of speaking to them. This study also discusses the potential of syllabus analysis as a method to complement needs analysis and to develop language support programs for specific contexts.
