Carnegie Mellon University
Argument Diagramming

The Argument Diagramming course is currently under development.


Course Description

The current version of this course contains 3 modules:

  1. Creating Argument Diagrams
  2. Evaluating Arguments
  3. Argument Diagramming for Interpreting Public Arguments and Longer Texts

Module 1 introduces the concept of argument diagramming as a way to visually represent the content and structure of an argument. It focuses on basic vocabulary and methods for determining argument structure. Each section of the module has a set of exercises for which students receive hints if they are stuck, and immediate feedback on their answers. Module 1 also introduces iLogos, the built-in argument diagramming software. This software allows students to build argument diagrams easily and quickly.

Module 2 introduces basic logical concepts such as validity and strength, and explores ways of evaluating arguments according to these logical standards. Arguments are classified as either deductive or non-deductive. In the section on deductive arguments, students are introduced to common argument forms, such as modus ponens, and common logical fallacies, such as the fallacy of affirming the consequent. In the section on non-deductive arguments, students are introduced to 4 basic argument types: statistical arguments, inductive arguments, abductive arguments, and arguments by analogy.

Module 3 builds on the skills that are introduced in Module 1, to introduce ways to tackle longer, more complex arguments. Students are introduced to basic rhetorical vocabulary and classifications, such as genre and exigence. Students are taught, through examples and tips, how to use these classifications to build a reasonable representation of the content and structure of arguments embedded in longer texts.
