This book offers critical perspectives on global literacies, connecting research, theory, and practice. An emerging concept in the literacy field, many scholars agree on the need for students to develop global literacies, yet few agree on a widely accepted definition. Based on a synthesis of the literature, the editors formulate a definition of global literacies with four dimensions, including: literacy as a human right in all nations around the world; critical reading and creation of multimodal texts about global issues; intercultural communication and reciprocal collaboration with globally diverse others; and transformative action for social and environmental justice that traverses borders. Taking this shared, proposed definition as a starting point, the chapters then offer contextualized examples of global literacies from K-12 and teacher education classrooms to make explicit links between research and practice. The contributors interact with and interrogate the book’s definition of global literacies using a common framework of critical theory. As such, this book provides both emerging and established scholars with critical frameworks for positioning global literacies in ways that are relevant, dynamic, and forward thinking.
