A Methodology of Languaging Self examines the role of critical methodology in literacy and language practices. Employing globally diverse autoethnographic approaches, it highlights diverse perspectives and lived experiences from marginalized authors. Through a decolonial lens, this book offers fresh insights into the complexities of literacy and language practices. Drawing together marginalized voices and experiences through creativity and authentic (re)presentation, this book considers how autoethnography and qualitative methods can work within literacy and language studies. Focusing on educational studies, chapters include research on the experience of Latinx students in a Florida classroom, developing teacher identity in Indonesia, and autoethnographic genealogical writing. Readers will benefit from the engagement with decolonial critical theory threaded throughout the book's multiple sections, in addition to the exploration of reflective and narrative methods in particular chapters. This book will be essential reading not only for qualitative researchers interested in ethnography and autoethnography but also for students and teachers in literacy and language-related fields.
