Abstract
The framework of practical research in special education was discussed in comparison with teaching reports and teaching records. Fifty research papers published on special issue of the Journal of Special Education devoted to "Current Issues in the Practice of Special Education Japan" were categorized according to their research contents. Ten papers on motor impairment were selected out of the fifty papers, and they were further meta-analyzed regarding contents of research, whether or not intra-individual changes were discussed, presentation methods of research results, duration of intervention, and other aspects. Methodological problems of practical research in special education were revealed by the meta-analysis. Coals in intervention, target behavior, design of variable control, and selection of parameters, intra-individual changes in research on positioning of the motor impaired are discussed for further improvement of research.
