By introducing a framework for culturally sustaining Systemic Functional Linguistics (SFL) praxis, Harman, Burke and other contributing authors guide readers through a practical and analytic exploration of youth participatory work in classroom and community settings. Applying an SFL lens to critical literacy and schooling, this book articulates a vision for youth learning and civic engagement that focuses on the power of performance, spatial learning, community activism and student agency. The book offers a range of research-driven, multimodal resources and methods for teachers to encourage students' meaning-making. The authors share how teachers and community activists can interact and support diverse and multilingual youth, fostering a dynamic environment that deepens inquiry of the arts and disciplinary area of knowledge. Research in this book provides a model for collaborative engagement and community partnerships, featuring the voices of students and teachers to highlight the importance of agency and action research in supporting literacy learning and transformative inquiry. Demonstrating theoretically and practically how SFL praxis can be applied broadly and deeply in the field, this book is suitable for preservice teachers, teacher educators, graduate students and scholars in bilingual and multilingual education, literacy education and language policy.
