In 1937, the Ministry of Education in Ontario published a document entitled "Programme of Studies for Grades 1 to VI of Public and Separate Schools" that became known amongst teachers as the "little gray book". The curriculum and pedagogy in the document enunciated a rupture or mutation in pedagogical discourse that broke with previously existing pedagogies. These changes resulted in the creation of a new knowledge archive in the system of schooling that defined what could be said about teaching, learning, children and schooling for the better part of the twentieth century. It also formed the terrain for the production of new educational subjects and subjectivities. (Contains 88 footnotes.)
