As discussed above, exactly what comprises a heterodox module will depend on the approach of the instructor and its level. There are essentially three alternatives in constructing a heterodox module. One way is to try to teach a single heterodox approach, such as Post-Keynesianism or Marxism. In that case, considerable depth would be achieved. Most of the examples discussed in section 6.2 are of this type. In each case, consistent with heterodox principles, the module would begin with a discussion of Post-Keynesian or Marxist, or whichever school's methodology, and its place in the history of economic thought. Thereafter, the topics covered will depend on the school being considered. Different heterodox schools have had different concerns and thus their literatures are skewed towards those issues. Space precludes a full discussion of all of these options here. However, reasonable guides to content can be based on treatments of the schools in any texts dedicated to them, history of economic thought texts and recent editions of journals devoted to the school.
The other ways to teach a heterodox module is to draw on the diversity of heterodox perspectives. One way is to anticipate the parallel perspectives approach discussed below and teach a series of topics, in each case considering a variety of heterodox perspectives. So, on successive topics of, say, methodology, the individual, firms and competition, the aggregate economy, the role of government and income distribution, one would consider the work of each of the heterodox perspectives chosen on those topics. In that way, the benefits of teaching heterodox material is achieved, as are the advantages of teaching multiple perspectives in parallel.
