How to Evaluate Arguments and Evidence in Texts

Khan Academy

This educational video provides a clear, step-by-step guide on how to identify and evaluate arguments within a text. Using a "rhetorical combat" framework, the narrator distinguishes between subjective opinions (like movie reviews) and formal arguments, emphasizing that valid arguments must be supported by verifiable evidence, data, and reasoning rather than just personal preference. The core of the video analyzes two opposing texts regarding a proposed "soda tax." The narrator models critical reading strategies by dissecting the claims made in both texts. He demonstrates how to identify logical gaps, such as a lack of evidence linking a tax to behavioral change, and how to spot potential unintended consequences, such as the disproportionate economic impact on lower-income individuals. He also encourages readers to consider what an author is *not* saying to understand the full scope of an argument. This resource is highly valuable for ELA classrooms focusing on non-fiction analysis, argumentative writing, or media literacy. It moves beyond simple definitions to model the actual metacognitive process of skepticism and critique. Teachers can use this to introduce the standards of tracing and evaluating arguments, helping students transition from reading for content to reading for structure and validity.
