This book enriches the discourse around Global Citizenship Education in teacher education through the example of a teacher's experience in a Canada-China Sister School reciprocal learning landscape. Instead of positioning global citizenship teaching and learning as a set of fixed goals to be attained by teachers alone, this book approaches global citizenship teaching and learning as unfinished lifework in progress and as situated curriculum problems to be inquired together by university researchers, school teachers, and students under the spirit of reciprocity and community. This reimagination of narratives, theory, and action start from collaborative and reciprocal learning partnerships among Chinese and Canadian researchers and teachers in the practicality of re-searching and re-enacting the purpose and meanings of twenty-first century education in a Canada-China Sister School setting.
