This chapter describes the creation and deployment of the Immersive Learning Level Editor (iLLE), a new cross-platform IVE engineered at the University of New South Wales (UNSW) Sydney. It illustrates the design considerations, discipline-specific workflows and pedagogical strategies employed in beginning to formulate a new and coherent pedagogy for immersive learning that is transferable, distributable and scalable across disciplines and platforms. In this way, it provides a number of methodological templates for contemplating discipline-specific immersive learning needs.
