Arguably, the best way to achieve the development of comparative and critical capacities is to combine the two approaches above into a 'parallel perspectives' approach. This approach brings together the elements of the other two approaches and its essence is summarised in Figure 9.
In terms of learning outcomes, students will gain awareness of a variety of substantive concepts (albeit possibly slightly narrower in scope than on any individual orthodox or heterodox module). However, the key to using the approach successfully is not to compromise on the need to be critical and comparative. The contrast between the perspectives is utterly crucial and must pervade the presentation and assessment of the module being taught.
Footnote: In theory, one could start with heterodox concepts. In an introductory module that makes most sense. In higher-level modules, in which students have most likely already studied some orthodox economics, the orthodox is most easily taught first.
