To address this shortcoming this researchreport provides a detailed exposition of Vygotsky’s theory of the cultural-historicaldevelopment of higher mental functions and then shows how his thinking aboutdefectology extends on the general theory. Following this exposition, the reportestablishes the extent to which Vygotsky’s ideas on defectology is consonant with, or achallenge to, the contemporary ideas of Inclusion and Inclusive education as it isunderstood and “implemented” in South African educational thinking and practice. Basedon this analysis, the report argues that Vygotsky provided a nuanced, and “moreinclusive” understanding of developmentally “normative” and “non-normative” childrenthan that provided in the South African policy on Inclusion and Inclusive Education.en© 2024 University of the Witwatersrand, Johannesburg.
