Toulmin’s model of argumentation is particularly valuable for college students because it provides a structured framework for analyzing and constructing arguments, skills that are essential across various academic disciplines and real-world situations.
By understanding Toulmin’s components—claim, evidence, warrant, backing, qualifier, and rebuttal—students can develop more coherent, persuasive arguments and critically evaluate the arguments of others.
