Michel Foucault's concept of normalisation is taken as a basis to explore the factors involved in the identification of dull, deficient and backward pupils in British Elementary Education between 1870 and 1914. Normalisation consists of the five processes of comparison, differentiation, hierarchisation, homogenisation and exclusion. These processes operate through dividing practices which distribute groups socially and are supported in this work by scientific ideas. In this instance, the norm of the intellect is the basis of the dividing practices. The empirical (...) focus opens with an examination of the main features of Elementary education. It then moves to consider the deliberations of the Royal Commission on the Blind, Deaf and Dumb, etc and those of the Departmental Committee on Defective and Epileptic Children. The analysis concludes with a consideration of the consequences of the Elementary Education Act, 1899, and its effects up until 1914. (shrink)
