Trade schools, universities, and programs for international students have begun to experiment with Content and Language Integrated Learning (CLIL) as a viable pedagogy for instruction, as the pedagogy of CLIL increasingly gains recognition as a practical form of language and content education in Europe and beyond, and its application in instructional settings becomes more diverse. Corresponding with CLIL´s growth, this book focuses on foreign language use during peer interactions in a new CLIL setting. It particularly concentrates on how to conduct research when the focus is on learner interactions. The theoretical background, research methods, and research instruments are explained in a brief and understandable manner. This book is intended for those interested in CLIL and peer interactions and includes a framework and ideas for investigating new CLIL contexts in a practical manner allowing undergraduate and graduate students to conduct their own research in these settings.
