Disabled and disability studies scholars and activists have challenged and are challenging the bio- and necro-politics of disability subjectivity through scholarship, art, activism, and online engagement. As this edition articulates, difference takes many forms, is intersectional, and is often characterized and codified by and through educational research. Acknowledging that difference is socially constructed poses challenges to the ablenationalism that undergirds not only complex systems of schooling, but the educational research on which these systems rest.
