This article analyzes the potential for reshaping disciplinary divides by engaging with theories and movements that relate to educational change. Generating educational structures that diverge from conventional discipline-based models are a common way of attempting contemporary educational reforms. Interdisciplinary approaches are analyzed in this paper relative to theories of change in the context of secondary level education, with a focus on Québec, Canada. The purpose of this article is to understand and give meaning to the concept of interdisciplinarity within educational change and reform. This exploration proposes a conceptual map for understanding educational change efforts that aim towards rethinking disciplinarity. A model case, NEXTschool, is included to illustrate the applied relevance of the theories and ideas explored in this paper.
