高等教育日益國際化，在英語不是母語的國家，使用英語作為學術內容的教學語言（English as a medium of instruction, EMI）已變得司空見慣。然而，愈來愈多人擔心，在未充分考量實施過程的挑戰情況下，EMI已成為全球快速增長的趨勢。作為一種複雜的現象，需提高認識EMI對教師和學生的正向和負向的影響，教師與學生的態度與觀點皆對EMI教學推動與成效有顯著的影響。國際化對護理教育的發展亦至關重要。鑑於此，實有必要了解與考量EMI教師與學生之影響。因此，本文將概述EMI定義和其導入原因，以及EMI教師和學生面臨的挑戰，以提供護理教育政策與學術單位推行EMI教學發展之借鏡。

Higher education is becoming increasingly internationalized, and English as a medium of instruction (EMI) for academic content has become commonplace in countries where English is not a native language. However, concerns are growing that the fast-growing trend of EMI lacks sufficient consideration of the related challenges with regard to implementation and impact. As a complex phenomenon, EMI requires increased awareness of its positive and negative implications for teachers and students. The attitudes and perspectives of teachers and students play a significant role in influencing the promotion and effectiveness of EMI teaching. Nevertheless, internationalization is essential for the advancement of nursing education. Therefore, it is imperative to understand the perspectives and challenges faced by teachers and students with regard to EMI and their readiness to embrace it. Therefore, in this article, we first define EMI and describe the reasons for its introduction and then discuss the challenges that teachers and students involved with EMI face in order to provide a reference for nursing education policymakers and academic institutions tasked with EMI development and implementation.
