While recent research trends in science education have focussed the collective attention at utilizing the science curriculum as a means towards positive social change, such efforts have largely been predicated on understandings of the nature of knowledge and truth as socially constructed entities. Through this lens of social constructivism, knowledge is said to bear the signature of individuals and institutions in power, and therefore extant knowledge is considered to be the vehicle for further oppression of disadvantaged groups. There are at least two ways in which this argument is deeply flawed—social constructivism accords to itself epistemic positions it denies others, and an intellectually honest application of its principles leads to a position where there is no way to distinguish between better or worse positions on issues. In contrast, the principle of social realism takes a ‘middle path’, acknowledging the social reality of knowledge construction but disavowing the relativism of social constructivism. Through this epistemological foundation, implications arise for curriculum theory—how is it that we may discriminate forms of knowledge for in/ex-clusion into the school curriculum? In this study, I consider the curriculum changes in the Ontario elementary science anxd technology curriculum. I ask two key questions: (i) What are the effects of the curriculum revisions on the knowledge content of the science curriculum? and: (ii) What are the characteristics of science pedagogy in fulfilment of these curriculum changes? I develop instruments to analyze curriculum documentation, and classroom pedagogy. The major findings of this project include: (i) the curriculum revisions have added environmental knowledge expectations with varying degrees of disconnection from the scientific content knowledge; (ii) knowledge expectations removed to accommodate environmental expectations constituted important scientific principles; (iii) environmental pedagogy in science classrooms reflected the disconnection between science and environmental knowledge, most obviously in the upper grades where the degree of boundary maintenance between knowledge forms was strongest; (iv) this disconnection between environmental and scientific knowledge forms inhibited the cumulative modality of knowledge (re)production. A discussion of results and the general principles of the importance of knowledge concludes the project.
