Over the years, various types of experimental projects have been carried out in Italy at different levels of education. CLIL practices have moved from limited small-scale experiments to elaborated projects involving technology, materials design and the creation of CLIL networks. This volume is a collection of works by both language and content teachers at all levels of education who have, in the past six years, embarked on a CLIL-type journey. The book is organized into two sections; the first part highlights some considerations that are more theoretical in nature. The purpose is to provide moments of reflection on these issues and/or bring to light other matters that merit further discussion.The second part is more pragmatic in nature dealing with proposals and projects already implemented in schools and at University.The chapters extol the numerous studies that have been going on in this field in the past decades. They contribute to the existing research in terms of small-scale explorations that highlight the development of CLIL over the years, a cautious progress that has led professionals to move from initial steps or simple trials to more complex tangible CLIL learning objects. A testimony of diversity in approaches showing how rich and vibrant the field of CLIL studies is and will continue to be in the future.
