Abstract
This paper argues that the two models of curriculum development currently used
to interpret Australian mathematics education history-the Colonial Echo model
and the Muddling Through model-are both deficient, and proposes a more complex
model-the Broad Spectrum Ecological model. This considers the physical,
social and intellectual forces operating within a specific environment. One small
aspect of mathematics education history, the introduction of probability teaching
into Australian schools, is used to illustrate the superiority of this model.
