About This MicroSim

An interactive argument dissector allows students to see the internal structure of arguments visually, reinforcing the distinction between premises and conclusions. It highlights indicator words (like "therefore," "since," "because") and maps the logic flow feeding from foundational premises to final conclusions.

Lesson Plan

Grade Level

9-12 (High School / IB TOK)

Duration

15-20 minutes

Prerequisites

  • Understanding that arguments are not just disagreements, but structured attempts to persuade based on evidence/logic.

Learning Objectives

  • Identify the premises and conclusion in a logical argument and trace the inferential connection between them.

Activities

  1. Exploration (5 min): Focus students on the default "dolphins/mammals" argument. Let them hover over the teal premise boxes and the amber conclusion box, noting how indicator words glow to show the inferential link.
  2. Guided Practice (10 min): Use the dropdown selector to examine increasingly complex arguments. Switch to the "Drag and Label" mode. Pick a student volunteer to drag the labels ("Premise 1," "Premise 2," "Conclusion") onto the correct parts of a random argument while asking the class to vote if the placement is correct.
  3. Assessment (5 min): Use the "Build Your Own" mode. Have students construct a basic two-premise, one-conclusion argument, then swap with a partner to identify the structural components.

Assessment

  • Accuracy during the "Drag and Label" group exercise.
  • Successful construction of an original, structurally sound argument using the 'Build Your Own' tool.

Quiz

Test your understanding of argumentation structure with this review question.

1. In the anatomy of a logical argument, what role does a "premise" serve?

  1. It provides the final claim that the speaker is trying to persuade the audience to believe.
  2. It acts as an indicator word (like "therefore" or "hence") connecting two unrelated thoughts.
  3. It provides the foundational statements, evidence, or reasons that logically support the conclusion.
  4. It is fundamentally an appeal to emotion that bypasses logical deduction entirely.
Show Answer

The correct answer is C. Premises are the structural building blocks of an argument; they offer the factual claims, evidence, and reasons from which the logical conclusion is drawn. Option A refers to the conclusion itself, not the premise.
