The contributions to this volume cover a wide range of topics, including dual language learners; Latino immigrant children; children who have hearing disabilities; parents' and teachers' beliefs about language development; early literacy skills of toddlers and preschool children; interventions; multimodalities in early literacies; writing; and family literacy. The studies were conducted in various early childhood settings such as child care, nursery school, Head Start, kindergarten, and primary grades, and the subjects in the studies represent the pluralism of the globe - a pluralism of language, backgrounds, ethnicity, abilities, and disabilities. This book was originally published as a special issue of Early Child Development and Care.
