Written from a critical perspective, this volume provides teachers, teacher educators, and classroom researchers with a conceptual framework and practical methods for teaching and researching the disciplinary literacy development of English language learners (ELLs). Grounded in a nuanced critique of current social, economic, and political changes shaping public education, Gebhard offers a comprehensive framework for designing curriculum, instruction, and assessments that build on students' linguistic and cultural resources and that are aligned with high-stakes state and national standards using the tools of systemic functional linguistics (SFL). By providing concrete examples of how teachers have used SFL in their work with students in urban schools, this book provides pre-service and in-service teachers, as well as literacy researchers and policy makers, with new insights into how they can support the disciplinary literacy development of ELLs and the professional practices of their teachers in the context of current school reforms. Key features of this book include the voices of teachers, examples of curriculum, sample analyses of student writing, and guiding questions to support readers in conducting action-oriented research in the schools where they work.
