Swales (1990) researched the structure
of introductions to academic journal articles. The schema
presented here is the pattern that he found occurring
in a majority of the articles. It is not a set of rules for how
you must write - rather, it is a useful guideline
for how to understand journal article introductions and how to
think about structuring your own information.
Check your understanding of Swales'
schema by performing task 4b.
