This book presents an evidence-based framework for understanding the literacy needs of adolescents. The premise is that educators and other critical stakeholders need to understand evidence-based principles in order to develop effective curriculum to meet the needs of diverse learners. Recommendations are provided for middle and secondary education, professional development, teacher education research and policy.At the center of the book are Eight Guiding Principles developed by the authors through a process that included an extensive review of research and policy literature in literacy and related fields, a comparison of National Standards documents, and visits to the classrooms of 28 middle and high school teachers across the United States. The Principles are broad enough to encompass a variety of contexts and student needs, yet specific enough to offer real support to those involved in program development or policy decisions. They provide an overarching structure that districts and teachers can use to develop site-specific curriculum that is both research-based and designed to meet the needs of the learners for whom they are responsible.Important Text Features: Organized to help readers understand empirically supported principles of practice that can be used to address literacy concerns in today's schools, each chapter that addresses one of the eight Principles follows a similar format:* The Principle is presented along with a brief explanation of the research base and a sample of national standards that support it.* One or more case examples spanning a wide variety of disciplines, grade levels, and local conditions - provide an in-depth look at the Principle in action.* A well-known adolescent literacy expert offers a response to each case example, giving readers an informed view of the importance of the Principle, how it is enacted in the cases, and examples of other work related to the Principle. Discussion questions are provided that can be used for individual reflection or group discussion.Principled Practices for Adolescent Literacy is intended as a text for pre-service and in-service upper-elementary, middle and high school literacy methods courses and graduate courses related to adolescent literacy, and as a resource for school district personnel, policymakers and parents.
