English Medium Instruction

English Medium Instruction (EMI) refers to the use of English as the language of teaching and learning in educational settings — particularly universities — where English is not the first language of students or teachers. EMI is distinguished by its primary focus on subject content: unlike Content and Language Integrated Learning (CLIL), EMI programs typically do not set explicit language learning goals alongside content goals. The medium of instruction switches to English; whether students also improve their English is often treated as a side effect rather than a designed outcome.

Also known as: EMI, English-medium education, English-mediated instruction, English-taught programs (ETPs)

In-Depth Explanation

EMI has become one of the most rapidly expanding educational trends globally over the past two decades, driven by the perceived link between English proficiency and international competitiveness in academia, research, and the knowledge economy. In many Asian national education systems — Japan, South Korea, China, Taiwan, Malaysia, Thailand — governments and universities have mandated or strongly incentivized the expansion of English-taught programs, particularly at the undergraduate and graduate levels.

The appeal of EMI rests on several assumptions:

  1. Research visibility: Publishing in English makes research accessible internationally; researchers trained in English-medium environments are assumed to participate more effectively in global academic discourse.
  2. Graduate employability: Employers in multinational contexts increasingly signal preference for graduates with high English proficiency, and universities market EMI programs partly on this basis.
  3. International enrollment: Universities can attract international students to English-medium programs without requiring language adaptation for different L1 groups.
  4. Incidental language development: Students’ English proficiency is expected to improve through sustained academic exposure.

The reality of EMI implementation is considerably more complex. Research reveals a wide range in EMI program quality — from genuinely high-quality content instruction in English, to programs where teachers switch frequently between English and the local language (code-switching), to programs using English-labeled courses that are taught substantially in the L1. The gap between EMI policy and EMI practice is one of the most documented phenomena in the field.

A critical distinction within EMI is between top-down EMI (government or institutional mandates driving adoption) and bottom-up EMI (faculty and departments adopting English medium by choice based on research community norms). Top-down EMI, the more common form in Asia, often leads to reluctant participation from faculty who lack adequate English proficiency for subject-matter instruction and students who lack sufficient L2 proficiency to benefit.

EMI also raises concerns about epistemic access: when learners cannot fully understand content due to L2 processing demands, even highly capable students may fail to learn subject matter effectively. Studies have documented that EMI students report significantly higher cognitive load and lower comprehension compared to equivalent content taught in the L1, particularly in early semesters.

History

EMI is not a new phenomenon — European universities historically operated in Latin as an academic lingua franca, and English has been the medium of instruction in Commonwealth universities since the colonial era. The contemporary EMI movement, however, dates to the 1990s–2000s, as the Bologna Process restructured European higher education and global university ranking systems (QS, THE, Shanghai) incentivized internationalization.

In Asia, EMI policy proliferation accelerated in the 2010s. Japan’s Top Global University initiative, South Korea’s BK21 program, and China’s Project 985/211 all included components requiring English-medium research and teaching outputs. Taiwan mandated English-taught courses at leading research universities. By the mid-2010s, the number of English-medium bachelor’s programs in non-English-speaking European countries had exceeded 10,000.

The research field of EMI studies crystallized around this policy boom, with Cambridge University Press launching the journal International Journal of Bilingual Education and Bilingualism and Routledge establishing dedicated EMI book series in the 2010s. Key researchers include Ruth Dearden (Oxford), Emma Dafouz (Madrid), and Ernesto Macaro (Oxford).

Common Misconceptions

  • “EMI is the same as CLIL.” The two are frequently conflated. CLIL has explicit dual goals (content + language); EMI typically has only content goals, with language treated as a byproduct. CLIL is primarily a K-12 framework; EMI is primarily higher education. CLIL is typically a foreign language context; EMI often operates in an ELF context.
  • “EMI automatically improves English proficiency.” Research consistently finds that language gains from EMI are smaller and less reliable than proponents assume. Without explicit attention to language alongside content, students often plateau rather than develop.
  • “Non-native English speaker teachers are less effective in EMI.” Teacher English proficiency is relevant, but research identifies clarity, subject expertise, and explicit language scaffolding as more important predictors of student learning than measured language proficiency.
  • “Students prefer EMI to L1 instruction.” Student attitudes toward EMI are highly variable. Studies in Japan, China, and Korea find significant anxiety, reduced participation, and lower satisfaction in EMI courses among students who perceive their own English as insufficient.

Criticisms

The most sustained criticism of EMI is that it constitutes a form of linguistic imperialism (to use Robert Phillipson’s blunt framing): by requiring English for academic legitimacy, global academic infrastructure systematically disadvantages non-native English speakers and privileges research produced in English, regardless of intellectual quality. This has knock-on effects on which knowledge gets produced, cited, and considered authoritative internationally.

A second critique concerns L1 academic literacy: extensive EMI at undergraduate level may reduce students’ ability to write and think at an academic level in their own language, producing graduates fluent enough in academic English for global participation but unable to contribute to L1 discourse and knowledge production in their own communities — a form of academic-register attrition.

Practical critiques include the Matthew Effect: students who arrive at EMI programs with higher English proficiency benefit disproportionately, while those with lower entry proficiency fall further behind, increasing within-cohort inequality even as the program aims to develop general English ability.

Social Media Sentiment

EMI generates significant discussion on academic Twitter/X, mostly from education researchers and policy critics. Faculty who teach in EMI settings frequently share frustrations about under-supported implementation — being required to teach in English with no training, reduced student comprehension, and pressure to lower content standards to compensate. Student perspectives appear on forums like WeChat Study Abroad groups, Reddit’s r/GradAdmissions, and university-specific Discords, where many report that EMI sounded better in the brochure than in the classroom. Defenders of EMI point to real career benefits for graduates and argue that criticism often comes from faculty resisting change rather than evidence of harm to students.

Practical Application

For learners deciding between EMI and non-EMI academic programs:

  • Assess your entry-level proficiency honestly. Research shows EMI benefits learners most when they arrive with at least a B2 level in English. Below B2, the cognitive load of content processing in English significantly interferes with both language and content learning.
  • Treat EMI as immersive exposure, not automatic improvement. If you’re enrolled in an EMI program hoping to improve your English, you need to actively notice and record language features — academic vocabulary, discourse markers, genre conventions — rather than just surviving lectures.
  • Be aware of code-switching in practice. EMI programs vary enormously in how much English is actually used. Before committing, ask current students about what actually happens in lectures.
  • For Japanese learners in non-academic EMI: The principle applies to any English-heavy workplace or study environment. Exposure is necessary but not sufficient; deliberate attention to language features drives development.
