About this resource

This quiz focuses on logical fallacies, specifically targeting students' ability to identify common errors in reasoning and argumentation. Based on the complexity of the examples and the critical thinking skills required, this material is appropriate for grades 9-12, particularly in English Language Arts, debate, or critical thinking courses. Students need a solid understanding of how arguments are constructed and the ability to analyze the logical structure of statements to distinguish between valid reasoning and flawed logic. The quiz covers eight major fallacies: ad hominem attacks, hasty generalization, slippery slope, straw man arguments, red herring distractions, ad populum appeals, post hoc reasoning, and false dilemmas. Success on this assessment requires students to move beyond surface-level comprehension and demonstrate analytical thinking by recognizing how each fallacy undermines logical discourse through different mechanisms of flawed reasoning. Created by Mike Ciurzynski, a teacher in the US who teaches grades 9-12. This quiz serves as an excellent tool for developing students' critical thinking and argumentation skills across multiple instructional contexts. Teachers can use it as a warm-up activity to activate prior knowledge before discussing persuasive writing or debate techniques, as guided practice during lessons on argument analysis, or as formative assessment to gauge student understanding of logical reasoning concepts. The quiz works particularly well for homework assignments that reinforce classroom instruction or as review material before summative assessments on argumentation and rhetoric. This assessment directly supports Common Core standards CCSS.ELA-LITERACY.RST.9-10.8 and CCSS.ELA-LITERACY.WHST.9-10.1, which require students to assess reasoning in texts and write logical arguments. The quiz also aligns with speaking and listening standards that emphasize evaluating arguments and identifying fallacious reasoning in presentations and discussions.
