Abstract
This paper is concerned with the contradictions and tensions in disability theory that have generated an uncertain professional knowledge base in relation to the education of students with disabilities. This tension has produced concern regarding the enculturation of teachers into reductionist understandings of disability that limit the development of inclusive educational environments. A critical realist lens is employed to better understand the boundaries and contributions of three disability models and their connections to education practice. This perspective asserts that the models are social constructions of a real phenomenon requiring critical reflection on their adequacy for explaining and informing real-world practices. It draws upon the work of Bhaskar and Danermark to present a framework for positioning disability theory in a manner that may prove a useful theoretical guide for practitioners.
