English-medium instruction (EMI) has been implemented in higher-education institutions around the world. This study examines the states of EMI-related professional development (PD) for Korean science and engineering professors and their perceptions of such programs. Faculty members at the three major science and engineering schools in Korea participated in a questionnaire survey and the follow-up interviews. The results show that the vast majority of them had not participated in pre- or in-service PD programs and had negative attitudes towards certified EMI-related PD programs mainly due to their institution’s strong emphasis on their research performance rather than the quality of their teaching. The study offers suggestions for future directions of EMI-related PD at institutions with a similar tendency.

英语媒介教学（EMI）已在世界各地的高等教育机构中实施。本研究调查了韩国科学和工程教授的 EMI 相关专业发展 (PD) 状态及其对此类课程的看法。韩国三大理工学院教职工参加了问卷调查和后续访谈。结果表明，他们中的绝大多数人没有参加过在职前或在职 PD 项目，并且对经认证的 EMI 相关 PD 项目持负面态度，主要是因为他们所在的机构非常重视他们的研究绩效而不是教学质量. 该研究为具有类似趋势的机构的 EMI 相关 PD 的未来发展方向提供了建议。
