Book excerpt: This book shows that reading-writing is a two-way street that is burgeoning with research activity. It provides a comprehensive and updated view on reading-writing connections by drawing on extant research and findings. It puts forward a new conception of literacy, one that establishes reading and writing connections as the primeval ground for building literacy science. It shows how an integrative view of literacy can have deep and lasting effects on conceptualizing literacy development in several orthographies and on improving literacy instruction and remediation worldwide. The book examines in detail such issues as modeling approaches to reading-writing relations, literacy development, reading and spelling across orthographies and integrative approaches to literacy instruction and remediation.
