This book engages readers in thirteen conversations presented by authors from around the world regarding the role that textbooks play in helping readers imagine membership in the nation. Authors' voices come from a variety of contexts - some historical, some contemporary, some providing analyses over time. But they all consider the changing portrayal of diversity, belonging and exclusion in multiethnic and diverse societies where silenced, invisible, marginalized members have struggled to make their voices heard and to have their identities incorporated into the national narrative. The authors discuss portrayals of past exclusions around religion, ethnicity, sexual orientation, as they look at the shifting boundaries of insider and outsider. This book is thus about "who we are" not only demographically, but also in terms of the past, especially how and whether we teach discredited pasts through textbooks. The concluding chapters provides ways forward in thinking about what can bedone to promote curricula that are more inclusive, critical and positively bonding, in increasingly larger and more inclusive contexts.
