Résumé: Using a sociocultural approach to critical action research, this book is a primer in doing reflexive, authentic inquiry research in teaching and learning for educators as teacher | researchers. Rather than the artificial dichotomy between theory and practice, the roles of teacher and researcher are instead seen in a dialectic relationship (indicated by the symbol “|” in teacher | researcher) in which each informs and mediates the other in the process of revising and generating new knowledge that is of benefit to those being researched. In addition to providing a theoretical foundation for authentic inquiry, Being a Teacher | Researcher provides a detailed framework with ideas and strategies that interested educators can apply in exploring teaching and learning in both formal and informal settings.
