Rhetorical Triangle Analysis

Overview

In this 45-minute lesson, 12th grade students will deepen their understanding of the rhetorical triangle—ethos, pathos, and logos—by applying these concepts to a real crime case study. They will collaboratively analyze rhetorical appeals used in true crime storytelling and synthesize their findings into a visual representation that demonstrates critical thinking and media literacy.

Standards Alignment

Common Core State Standards (English Language Arts - Literacy in History/Social Studies and English Language Arts, Grade 11-12):

• CCSS.ELA-LITERACY.RI.11-12.6: Determine an author’s point of view or purpose in a text in which the rhetoric is particularly effective, analyzing how style and content contribute to meaning.
• CCSS.ELA-LITERACY.RI.11-12.8: Delineate and evaluate the reasoning in seminal U.S. texts, including the application of rhetorical appeals.
• CCSS.ELA-LITERACY.SL.11-12.1: Initiate and participate effectively in a range of collaborative discussions with diverse partners on topics, building on others’ ideas and expressing their own clearly.
• CCSS.ELA-LITERACY.W.11-12.2: Write informative/explanatory texts to examine and convey complex ideas clearly and accurately.
• CCSS.ELA-LITERACY.W.11-12.4: Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.

Learning Objectives

By the end of this lesson, students will be able to:

• Identify and define ethos, pathos, and logos in the context of rhetorical analysis.
• Analyze a true crime case study to extract examples of each rhetorical appeal.
• Collaboratively create a visual representation of the rhetorical triangle highlighting ethos, pathos, and logos.
• Justify their choices with clear evidence from the case study.
• Engage in peer discussions to deepen understanding and refine analysis.

Materials Needed

• Copies of a brief true crime case study article (prepared in advance)
• Whiteboard and markers or chart paper
• Colored markers, large poster paper or digital presentation tools (e.g., Google Slides, Jamboard)
• Rhetorical Triangle handout (definitions/examples of ethos, pathos, logos)
• Student notebooks or digital devices for note-taking

Lesson Breakdown

1. Introduction & Review (7 minutes)

• Begin with a quick recall exercise: ask, “What are the three parts of the rhetorical triangle?” Write responses on the board: Ethos, Pathos, Logos.
• Briefly review each appeal with examples relevant to real crime or media discourse (e.g., ethos as credibility of a detective, pathos as victim impact, logos as factual evidence).
• Distribute the Rhetorical Triangle handout for reference.

2. Case Study Reading & Annotation (10 minutes)

• Hand out the true crime case study article (select a concise, media-rich, age-appropriate account).
• Students individually read and annotate, marking where they think ethos, pathos, and logos appear. Use colored pens or highlight key passages.
• Prompt: “Highlight one example of ethos, one of pathos, and one of logos.”

3. Group Discussion and Analysis (10 minutes)

• Divide class into groups of 4-5 students (total 4 groups).
• Each group shares their annotations and discusses why they categorized specific parts as ethos, pathos, or logos.
• Encourage students to question and build on ideas, fostering depth of understanding.

4. Creating the Rhetorical Triangle Visual (12 minutes)

• Provide groups with poster paper and markers or access to digital collaboration tools.
• Each group creates a visual rhetorical triangle for the case study:
  • Label each apex Ethos, Pathos, Logos.
  • Place examples from the text with brief explanations next to each side or corner.
• Circulate and prompt critical thinking: “How does this example build credibility? Evoke emotion? Present logical arguments?”

5. Gallery Walk & Peer Feedback (5 minutes)

• Groups display their triangles around the room or share screens if digital.
• Students do a silent gallery walk, leaving sticky notes or written comments with constructive feedback or insightful questions on other groups’ work.

6. Exit Ticket / Wrap-Up (1 minute)

• One sentence to write: “Which rhetorical appeal do you think is most effective in true crime storytelling and why?”

---

Assessment

• Informal formative assessment through group discussion participation and observation.
• Evaluation of the rhetorical triangle visuals for accuracy, depth of analysis, and connection to the case study evidence.
• Exit ticket checks for individual understanding and critical reflection.

---

Differentiation Strategies

• Provide scaffolding by pre-identifying a few key rhetorical appeal examples in the case study for students who need support.
• Challenge advanced students to analyze the text’s tone, bias, or counter-arguments within each rhetorical appeal.
• Allow students to choose spoken, written, or visual modes to present their triangle for diverse learning styles.

Reflective Extension (Optional Homework)

Assign students to select their own recent news article or true crime podcast transcript and identify ethos, pathos, and logos examples. They may prepare a short written or media presentation for future sharing.
