Bilingual language exposure is highly variable, with wide-ranging influences on early language skills. This underscores the need for understanding what to expect in early language acquisition so that those with typical language development can be differentiated from those who are struggling or at risk, and so requiring early intervention. One of the key ways to look at language development in very young children is to investigate their vocabulary development, and for bilingual children, this means measuring their abilities in both languages. This book takes an important step in this direction: it documents the expressive vocabularies of children aged 16-45 months who were exposed to different language pairs and bilingual contexts, and investigates the risk and protective effects of various environmental factors. In each of the six studies, the vocabularies of typically-developing children were measured using the vocabulary checklist of the MacArthur-Bates Communicative Development Inventories and its adaptations to other languages. Developmental and language background questionnaires provided additional information on children’s developmental history, risk factors for language impairment, language exposure, as well as parental education and occupation. This harmonised methodology was designed within COST Action IS0804 (Language Impairment in a Multilingual Society: Linguistic Patterns and the Road to Assessment). The outcomes of this cross-linguistic research contribute towards answering theoretical questions regarding early bilingual vocabulary acquisition. They also have clinical relevance, potentially assisting speech-language pathologists and those interested in early language development in distinguishing between clinically significant bilingual delays and the natural consequences of bilingual exposure. This book was originally published as a special issue of the International Journal of Bilingual Education and Bilingualism.

This is the first international and interdisciplinary handbook to offer a comprehensive and an in-depth overview of findings from contemporary research, theory, and practice in early childhood language education in various parts of the world and with different populations. The contributions by leading scholars and practitioners are structured to give a survey of the topic, highlight its importance, and provide a critical stance. The book covers preschool ages, and looks at children belonging to diverse ethno-linguistic groups and experiencing different histories and pathways of their socio-linguistic and socio-cultural development and early education. The languages under the scope of this handbook are identified by the contributors as immigrant languages, indigenous, endangered, heritage, regional, minority, majority, and marginalized, as well as foreign and second languages, all of which are discussed in relation to early language education as the key concept of the handbook. In this volume, “early language education” will refer to any kind of setting, both formal and informal (e.g. nursery, kindergarten, early childhood education centers, complementary early schooling etc.) in which language learning within a context of children's sociolinguistic diversity takes place before elementary school.

Affirming the Rights of Emergent Bilingual and Multilingual Children and Families explores how the philosophy, principles, and practices of the internationally acclaimed Municipal Preschools and Infant Toddler Centers of Reggio Emilia, Italy, advance the social justice and linguistic human rights of emergent bilingual and multilingual children and their families, particularly immigrants and refugees. The book is driven by the authors’ research-based discourse including an interview with Reggio Emilia educators and direct observations in the Preschools and Infant–toddler Centers in Italy. Chapters include survey and follow-up interviews, and classroom examples from U.S. early childhood educators inspired by the Reggio Emilia approach some of whom are in multilingual settings. Recommendations are included for practitioners who are intentional about advocating for the rights of emergent bi- and multilingual young children. Also included are the researchers’ interpretations and reflexive narratives on contextuality, intersectionality, and intertextuality, which interweave theories and practice. The insightful examinations of scholarly work and the critical review of the distinctive features of the Reggio Emilia philosophy contribute to an early childhood education transformative lens that challenges the status quo of inequities and foregrounds the linguistic and cultural rights of learners who speak different languages. The authors review research and theory that inform the latest developments in culturally and linguistically responsive practices in innovative early education (infant through pre-k), family participation, and teacher preparation and development. Of general interest to educators and researchers around the world who work to ensure the rights of emergent language learners, this is an essential text for upper-level and graduate students, early childhood educators, educational and community leaders, administrators, and researchers.

This book examines the language development of two children from the ages of two till four, who are growing up exposed to English, Swiss German and French. Its aim is to ascertain the importance of different environmental factors in fostering active trilingualism. These factors include the quantity of input for each language, whether or not the societal language is spoken in the home, and the conversational style of the caregivers. Although increasing numbers of children are being raised trilingually, research in this field is scarce; this study thus makes an important contribution to our knowledge of trilingual language acquisition. A special point of interest lies in a comparison of the acquisition of two minority languages by a single child, since this allows us to pinpoint more precisely how the development of non-societal languages can be influenced. This book will be of considerable interest to researchers and students working on multilingualism and language acquisition alike.
