This book focuses on practical use of the Dominant Language Constellations (DLC) approach, not only in formal settings, but also in social and family domains. It addresses the daily needs of all those who deal with multilingual reality. The key unique feature of the volume is its focus on giving practical advice, recommendations, and suggestions that can help individuals deal with real-life multilingual situations. It covers multiple social and geographical contexts, bringing insights into working directly with family members, children and adults, and educational stakeholders. While based on DLC theory and empirical studies, this volume appeals directly to practitioners, both in-service and future teachers, as well as teacher educators, parents and social workers in multilingual settings.
