What This Standard Means
What Students Need to Do
- Students trace how each writer builds a position through claims, reasons, evidence, and counterclaims. They compare each writer's choices and judge the accuracy, relevance, logic, and persuasive effect of the support.
What Mastery Looks Like
- Given paired articles, students can map each central claim, reasons, evidence, and counterclaims. They can explain which argument is more valid and which is more persuasive, using specific details from both texts.
Common Misconceptions
- Students may assume the argument they agree with is automatically more valid. They may count pieces of evidence without checking source credibility, relevance, or gaps in reasoning. They may also confuse emotional appeal with sound logic.
How to Assess It
- Give students two short opposing paragraphs. Ask them to name each claim, identify one support move, and decide which is more valid and which is more effective, citing evidence.
Lesson moves
Ways to Teach It
Cut apart two editorials into claims, reasons, evidence, and counterclaims; students sort and rebuild each argument, then compare structures.
After reading paired editorials, discuss which author uses stronger evidence and which better persuades the intended audience, citing one line for each.
Play Argument Referee: teams score evidence from two texts for relevance, credibility, sufficiency, and logical connection, then defend each score.
Compare two school phone policy statements, then recommend one to the principal based on validity and likely effect on students.
