This comprehensive introductory textbook gives students the framework and tools to become great debaters and use those skills to further civil and respectful responses on contentious topics. Focusing on core concepts and skills of research, reasoning, and argumentation with a special focus on debate rhythms, the book builds students' ability to express ideas and respectfully dissent, ultimately improving their individual resilience in adverse circumstances and encouraging the emergence of communal values in society. An Invitation to Debate takes students on a step-by-step preparation of case research, speech composition, rebuttals, and resolutions. It is not specific to a particular debate style, allowing professors to use the book across a variety of procedural types, including policy, British Parliamentary, Lincoln-Douglas, International Public Debate Association, world schools, and Coolidge. As the most up-to-date debate textbook, An Invitation to Debate will show students how to use AI technologies to aid (but never replace) their own case preparation. Throughout the book, students will be challenged to consider opportunities for debate to create more civil and fruitful discussion in their daily lives and on the world stage--where respectful debate can break through political barriers and counteract social injustices.
