國際教育的發展是近年來台灣在高等教育領域的重要課題，而全英語授課或全英語教學，則是國際教育的重要指標之一。各大專院校積極推展全英語教學，一方面藉以提升本地學生的英語能力及國際觀，一方面亦可用來招收外籍學生。但至今有關全英語教學實質影響的相關研究，仍相對缺乏。本研究採用重要性-表現分析法，分析兩組在觀光餐旅相關領域的畢業生的工作表現；其中一組畢業於四年全英語授課的國際學程，另一群則由傳統中文授課科系畢業。研究結果顯示在選定的32項職能指標中，全英語教育畢業生在其中四項，例如『英語溝通能力』以及『多元文化職場中的工作能力』稍微領先。在需要加強的職能上，全英語教學的畢業生則表示需要增進在『專業知識』方面的學習。

The importance of international education among higher education in Taiwan has been growing in recent years. Particularly, courses taught in English, also known as EMI (English as Medium of Instruction) courses, have been growing in popularity. However, in the field of tourism and hospitality, there are still very few programs that offer all-English education, and little research is available to demonstrate the benefits of such courses compared to conventional, Chinese-based courses. This study therefore aims at evaluating the outcome of EMI courses using Importance Performance Analysis (IPA) method. Job performance of students who graduated from EMI program is compared to that of conventional, non-EMI students. The results show EMI students hold slight advantages in a few areas such as “English communication” and “ability to work in multicultural environment.” On the other hand, one area EMI program needs to improve on is the delivery of “professional knowledge.”
