Abstract
Borrowing from scientific logic, the technical writing teacher can demonstrate differences between the way researchers/writers problem solve and the way readers comprehend written reports that are roughly parallel to the differences between deductive and inductive logic. As three pyramid theories of writing and their application in university and industry classrooms demonstrate, learning both systems of logic and how to transpose one into the other enables students to understand and structure their information from their readers’ viewpoint. In this logical context, opening with the conclusion finally makes sense to most writers.
