Full Idea
In Etchemendy's Interpretational Semantics (perhaps better called 'Substitutional') we keep the situation fixed and vary the interpretation; in Representational Semantics ('Modal'?) we keep interpretations fixed but consider varying situations.
Gist of Idea
Etchemendy says fix the situation and vary the interpretation, or fix interpretations with varying situations
Source
report of John Etchemendy (The Concept of Logical Consequence [1999]) by Stephen Read - Formal and Material Consequence 'Inval'
Book Ref

A Reaction
[compressed] These are semantic strategies for interpreting logic, so they are two ways you might go about assessing an argument.
