The conceptual frameworks discussed in this paper draw upon the work of Benner and Sutphen (2007) and Engeström (1994).

They suggest that knowledge must be constantly integrated within the curriculum through pedagogies of interpretation, formation, contextualisation and performance. These pedagogies present a framework, which may enhance our understanding of the impact of simulation upon student learning. Engeström's work on activity theory, recognises the links between learning and the environm...
