Part of being able to evaluate an argument is being able to identify the elements and structure of the argument. What are the claims? What evidence is provided? What assumptions are made?
An argument map is a visual way of outline the structure of an argument. Aulink provides six tutorials about creating arguments maps at http://austhink.com/reason/tutorials/. Each tutorial presents both information and exercises so students can learn and practice argument mapping. Auslink is trying to sell their argument mapping software, but you don’t need to purchase anything to use and benefit from the tutorials.
