Who said the following? "Discursive practices are not purely and simply modes of
manufacture of discourse. They take shape in technical ensembles. in institutions. in
behavioral schemes. in types of transmission and dissemination. In pedagogical forms that
both impose and maintain them"
Michael Foucault
The passage is by Michel Foucault. It describes discourse as sustained through institutions, technologies, habits and educational practices, rather than consisting only of statements or words.
