The Structure of Argument teaches students how to approach, develop, and defend arguments one element at a time. This concise but thorough text carefully scaffolds argument for students, explaining approaches to argumentation, critical reading, and argument analysis. The major components of argumentation--claims, support, assumptions, logic--are explained in depth, and a robust research section shows students how to find, incorporate, and build on existing arguments. The Ninth Edition has been updated with more sourced readings than ever before, including a section of debates on unsettled current topics, further reinforcing the importance of research and synthesis. With its value price tag, The Structure of Argument is an affordable, accessible resource for the argument classroom. The Structure of Argument is available with LaunchPad Solo for Readers and Writers.
