In an increasingly interconnected world, where colonial legacies continue to resonate in academia, this research book examines the methodological uncertainties that arise when adopting a decolonial approach to research. Through a series of interrelated chapters, a rich and complex narrative is woven that challenges the norms of traditional research methodologies by proposing new ways of understanding and approaching various issues related to the field of English Language Teaching (ELT) in Colombia: doctoral education, text authorship, critical, bilingual, and intersectional identities, and language policies. This book is an invitation to question the familiar, embrace uncertainty, and explore new ways of doing research that recognize and value the rich diversity of voices and experiences in a world that demands decolonization in all spheres, including education in general and the field of ELT education in particular.
