This research proposal reviews the literature on the development of mobility skills in students with severe physical disabilities and proposes a single-subject study, using a multiple baseline across subjects design, to evaluate effects of the Mobility Opportunities Via Education (MOVE) Curriculum on the mobility skills of sitting, standing, and walking and on social interactions of subjects. The literature review examines the relationship between motor development and cognitive development, the role of the environment, the "zone of proximal development" and motor development, and the interventions of structured guidance and sensory stimulation. The need for evaluating the effect of the MOVE Curriculum on the development of functional mobility skills is explained. The proposed study would involve provision of training in the MOVE Curriculum to teachers that serve students with severe physical disabilities, selection of four to five such students, definition of functional mobility for each child, application of the curriculum, and evaluation.
