Book excerpt: This book provides critical insights into the English-medium instruction (EMI) experiences which have been implemented at a number of universities in countries such as China, Finland, Israel, the Netherlands, South Africa, Spain and the USA, which are characterised by differing political, cultural and sociolinguistic situations. In particular, it reflects on the consequences of implementing EMI as an attempt to gain visibility and as a strategy in response to the need to become competitive in both national and international markets. The pitfalls and challenges specific to each setting are analysed, and the pedagogical issues and methodological implications that arise from the implementation of these programmes are also discussed. This volume will serve to advance our awareness about the strategies and tools needed to improve EMI at tertiary level.
