Outline of Final Research Achievements

The comparison of development of inclusive education among countries was conducted from the perspective of the "situation of integration of persons with disabilities" in the latter half of the 20th century. As objective method for grasping the development of inclusive education, a mathematical model has been tried to develop. In this study, as a starting point, the development of a mathematical model was carried out using the change in the number of students who were instructed by a regular class. It was calculated that the number would increase to about 500,000 in the early 2030s. In the future, we would like to promote modeling of various transitional situations related to inclusive education so that it can be applied to inter-municipal and international comparisons.

Academic Significance and Societal Importance of the Research Achievements

これまでのインクルーシブ教育や特別支援教育の展開状況の数値表記は、「何年間で何倍に増加した」といった比率での表現や、特別支援学校在籍者が「全体に占める割合の変化」の表現が基本であった。この表現だけでも変化の基本の傾向にある程度は言及できるが、どのように変化しているのかや、特に今後の予測を行うことができなかった。本研究では、変化動向を数理モデルで表現することで、今後の推移予測を効果的に行えるように試みたものである。より客観的・具体的に傾向分析や予測ができるようになったことで、変化の背景要因の議論が促され、将来の制度設計などにも新たな議論の視点を得ることができた。
