Exploring the history of disability and special education practices from the seventeenth to the twenty-first century indicates similar ideas and similar human approaches that have developed independently over time. People who survived the eugenics movement were placed in asylums and segregated special schools. In Europe and America, the general systems theory has been applied as a "logico-mathematical" discipline to include students of all special needs categories in their placements and education. The systems approach to special education practices has evolved from a historical model of diagnoses and cures to the biological and ecological models, integrating technology as the driving force in implementing curriculum, instruction, and assessment.
