Serial Expansion

Martin & Rose (2007: 199):

The strategy of predicting phases of discourse with macroThemes and hyperThemes constructs a ‘hierarchy’ of periodicity of smaller units of discourse ‘scaffolded’ within larger units. But there are alternative ways of constructing unfolding discourse so it is sensible to the reader. One way to highlight this is to compare hierarchy with an alternative strategy for expanding text, which is the strategy Tutu uses to build up his argument. We can call this ‘serial expansion’.

[1] As previously demonstrated, it is not possible to predict what follows introductory paragraphs (macroThemes) and topic sentences (hyperThemes), except with the benefit of hindsight. Instead, in writing that conforms with these pedagogical principles, these "Themes" are elaborated by what follows. That is, Martin & Rose have confused textual transitions (conjunctive relations) with textual statuses (thematic prominence).

[2] The unacknowledged source of the notion of a ‘hierarchy of periodicity' is Halliday (1981).

[3] To be clear, Martin & Rose have not identified the units of which these higher level Themes are elements, nor discussed their complementary elements: higher level Rhemes.

[4] To be clear, these 'alternative ways' are the non-structural resources of the textual metafunction: conjunction, reference, ellipsis-&-substitution, and lexical cohesion.

[5] As will be seen, this alternative strategy of 'serial expansion' is cohesive conjunction, the textual resource that Martin & Rose have already unwittingly drawn on in describing their higher level Themes and News (see [1] above).
