Advocates of CLIL (Content and Language Integrated Learning) have extolled the virtues of this approach to fostering both content and language alike. However, the generalised and varied implementation of EMI (English as a Medium of Instruction) in universities worldwide has led many lecturers to question these claims. This paper presents a CEFR (Common European Framework)-based model for measuring the impact of EMI at the tertiary level, the aim being to provide further evidence of the progress made in language-learning in modules taught in a foreign language. Using questionnaires based on the revised and refined CEFR descriptors from EAQUALS (Evaluation and Accreditation of Quality in Language Services), students answer an initial self-assessment survey about their background and language skills, which is controlled by a final questionnaire targeting their perceived progress throughout their instruction. Designed from the ground up with the CEFR as a backdrop, this method can be easily tallied with objective assessment to uncover data about students' linguistic performance in CLIL contexts.

I. CLIL AS A CONTESTED APPROACHMost universities around the globe now offer full or partial degrees taught through a foreign language. English has long been the language of science, but these degrees have made English "the language of higher education in Europe" (Coleman 2006: 1). Part programmatic development, part explicit competition in a wider tertiary environment, English has become the de-facto language for academic discourse and those refusing to provide English-taught modules endanger their global scientific visibility (Alexander 2006). Particularly in Europe, there is a strong consensus on the methodological approach to be used when a content module or degree is taught through a language other than the students' mother tongue (often in English as the Medium of Instruction, or EMI). Content and Language Integrated Learning (CLIL) "is part of mainstream school education in the great majority of countries at primary and secondary levels" (Eurydice

Unlike immersion programmes, multilingualism and CLIL assume that the role of language for the participants need not be transparent for either lecturer or student (Lagasabaster and Sierra 2010) and devise interventions to foster linguistic skills alongside content.Rather than being a strict method, CLIL is "essentially methodological" (Marsh 2008: 244). Its theorists claim it fosters a flexible, inclusive approach which can be applied through many specific methodologies, since both content and language are integrated. . Lecturers nevertheless attempt to overcome these linguistic hurdles with a number of mediatio...
