Discrete Choice Experiment about English-Mediated Instruction in Korea

The questionnaire was structured into three sections. First, for demographic information, we collected the respondents' background details, including their EMI experience, sex, first language, current degree program, and major. The second was the perception of EMI and English Language Courses. The respondents were asked about their positive and negative perceptions of both EMI and English language courses. Third, DCE. This section presents two hypothetical course descriptions per choice set, asking respondents to select their preferred options. This study focused on students' Willingness-to-Pay (WTP) for course selection by examining their perceptions of the importance of various course attributes, including course delivery method, subject type, grading system, instructor nationality, and tuition fees.
