Book excerpt: This book addresses heated issues in Integrated Content and Language in Higher Education (ICLHE) teacher training with specific emphasis on case studies that will contribute to inform future ICLHE teacher training research and practice. One of the most significant phenomena concerning language in higher education in modern time has been the rise of content subjects taught in an additional language, English being the chosen language in most of the cases. The implementation and teaching of Integrated Content and Language in Higher Education (ICLHE) or English as Medium of Instruction (EMI) is a multifaceted, dynamic process that cannot be considered in isolation. Indeed, there are a multitude of interrelated factors that pivot on situating the learner in the centre of the learning process and which directly shape ICLHE teacher training. This is why training lecturers to teach learners in an additional language in Higher Education has been considered a challenge for the profession as numerous publications demonstrate. This book brings together the innovative work of different researchers around the world on how universities, researchers and practitioners are facing and developing Integrating Content and Language in Higher Education (ICHLE) teacher training. All in all, the different contributions reflect different issues that play a fundamental role in the design of effective ICLHE professional development and provide data and reflections that will hopefully contribute to inform future ICLHE teacher training programmes. Teacher Professional Development for the Integration of Content and Language in Higher Education will be an important resource for academics, researchers, and advanced students of Education and Teacher Training Research and Practice. The chapters included in this book were originally published as a special issue of Innovation in Language Learning and Teaching.
