While Montessori's theories appear to have had greater influence and official support in the state schools of New South Wales and in the kindergartens of South Australia, the extent of her influence in Victoria is not widely discussed in educational literature. This thesis tries to examine the ways in which Montessori's theories affected educational ideas and practices in Victorian state schools and free kindergartens between 1912 and 1930. Some comparison is made among the states of South Australia, New South Wales and Victoria as to the extent and reasons for the differing degrees of influence Montessorian ideas exerted over the educational developments in the three states.
It is suggested that Montessori's ideas did influence the attitudes of some educators in Victoria but that lack of finance and over-crowding in classrooms prevented the implementation of a Montessori programme. The lasting effect of Montessori does not seem to have differed greatly in the three states.
