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.
