Abstract
Disability theory discusses the interplay between impairment and disability as though they can be identified separately. More recently, scholars in the field have sought to move beyond the dichotomy to an interactional model. This article uses evidence from a longitudinal ethnographic case study to demonstrate how notions of interaction and relation need to be understood within context. Socio-cultural theory makes explicit a situated understanding of participation and experience and demonstrates how classroom environments 'call forth' disability. Findings reveal how classrooms as educational contexts mediate the experience of a student with a learning impairment. The evidence shows how a classroom draws on the wider regimes of competence at the institutional level to create particular experiences for students. The challenge for teachers and other support staff in schools is to reflect on and influence the dynamic of impairment/disability within their classroom and school context in order to support appropriate participation and learning.
