In order to study the impact of a Flipped classroom design in a “World Economy” first-year English as Medium of Instruction (EMI) module, this poster discus which are the language requirements that students have at the Faculty of Business and Economics at a traditional, face-to-face (Face2Face) Spanish publicly-funded institution, the University of Oviedo (Spain). A Flipped Classroom instructional design combines different types of teaching and learning elements to promote students' performance and involvement in their own learning. Multimedia academic materials and active learning practices constitute the core of the design and give the opportunity to move content coverage outside the classroom, in order to spend in-class time to promote high order thinking skills. Nevertheless, as this module follows a Content and Language Integrated Learning (CLIL) approach, both academic content, necessary language skills and fluently communication requirements for the active involvement are also introduced in the instructional design. Thus, the central idea displayed in the poster is the different levels of language requirements this EMI module has and how different communicative skills are structured to inform students and professors about the language skills required.
