The Handbook of Critical Literacies aims to answer the timely question: what are the social responsibilities of critical literacy academics, researchers, and teachers in today?s world? Critical literacies are classically understood as ways to interrogate texts and contexts to address injustices and they are an essential literacy practice. Organized into thematic and regional sections, this handbook provides substantive definitions of critical literacies across fields and geographies, surveys of critical literacy work in over 23 countries and regions, and overviews of research, practice, and conceptual connections to established and emerging theoretical frameworks. The chapters on global critical literacy practices include research on language acquisition, the teaching of literature and English language arts, Youth Participatory Action Research, environmental justice movements, and more. This pivotal handbook enables new and established researchers to position their studies within highly relevant directions in the field and engage, organize, disrupt, and build as we work for more sustainable social and material relations. A groundbreaking text, this handbook is a definitive resource and an essential companion for students, researchers, and scholars in the field.
