Ethos: Establishing CredibilityActivities & Teaching Strategies
Active learning works for this topic because ninth graders need to see ethos not as abstract theory but as a tool they can use and evaluate. These activities move students from identifying credibility markers to practicing them, making abstract concepts concrete through discussion and revision.
Learning Objectives
- 1Analyze how specific word choices and cited experiences contribute to a speaker's perceived credibility.
- 2Evaluate the ethical implications of using misleading or fabricated credentials to persuade an audience.
- 3Compare and contrast the primary methods of establishing ethos in written arguments versus spoken presentations.
- 4Identify instances where a speaker establishes ethos by appealing to shared values or common ground.
- 5Create a brief persuasive statement that effectively employs at least two distinct strategies for building ethos.

Pairs: Ethos Detective Hunt
Partners read paired excerpts from persuasive texts, one strong in ethos and one weak. They highlight three ethos strategies in the strong example and suggest fixes for the weak one. Pairs share one insight with the class.
Prepare & details
How does a speaker establish credibility when they lack formal authority?
Facilitation Tip: During Ethos Detective Hunt, circulate and ask pairs to explain why they chose a particular quote as an ethos marker before they share with the class.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Small Groups: Credibility Role-Play
Groups draw scenarios lacking formal authority, like a student pitching a school policy. Each member delivers a 1-minute pitch building ethos through stories or expertise. Group votes on most credible and discusses why.
Prepare & details
Analyze the ethical implications of misrepresenting one's expertise to persuade an audience.
Facilitation Tip: In Credibility Role-Play, provide sentence stems like 'I know this because...' to support students who struggle with improvisation.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Whole Class: Ethos Revision Gallery Walk
Students write short ethos intros for arguments on a current issue. Post them around the room. Class walks, notes sticky feedback on strengths and improvements, then revises originals.
Prepare & details
Compare different strategies for building ethos in written versus spoken arguments.
Facilitation Tip: For Ethos Revision Gallery Walk, assign each group a specific audience (e.g., classmates, school board) so revisions are audience-driven, not generic.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Individual: Ethos Self-Analysis
Students record a 30-second video pitch on a personal goal, then transcribe and annotate ethos elements used. They rewrite for stronger credibility based on a rubric.
Prepare & details
How does a speaker establish credibility when they lack formal authority?
Facilitation Tip: During Ethos Self-Analysis, remind students to look for patterns across their writing, such as repeated use of personal stories or cited experts.

Teaching This Topic
Teachers approach this topic by modeling how credibility feels from the audience’s perspective first, then naming the strategies. Research shows students learn ethos best when they analyze failures of credibility alongside successes, so include examples where trust is broken. Avoid overemphasizing formal credentials—focus instead on how expertise, character, and shared values operate together.
What to Expect
Students will move from spotting ethos in texts to intentionally using ethos in their own communication. Success looks like students confidently explaining how trust is built and revising their work to strengthen credibility for specific audiences.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionEthos comes only from degrees or job titles.
What to Teach Instead
During Credibility Role-Play, provide scenarios where characters have no formal credentials but build trust through personal stories or shared experiences. After the role-plays, debrief by asking students which strategies felt most authentic, even without titles.
Common MisconceptionStrong logos makes ethos unnecessary.
What to Teach Instead
During Ethos Detective Hunt, give pairs two versions of the same argument—one with ethos and one without—and ask them to reflect on which version they trust more and why. Use their responses to highlight how ethos primes audiences for logos.
Common MisconceptionAll ethos strategies manipulate audiences.
What to Teach Instead
During Ethos Revision Gallery Walk, include examples of ethos used ethically (e.g., Martin Luther King Jr.) and unethically (e.g., false claims). Have students compare how each makes them feel as readers and discuss the ethical stakes.
Assessment Ideas
After Ethos Detective Hunt, distribute a new short excerpt. Ask students to identify one ethos strategy and explain in one sentence why it builds trust with that specific audience.
During Credibility Role-Play, present students with two scenarios: one where a speaker uses expertise to build ethos, another where they use shared values. Ask students to write one sentence for each explaining which strategy is being used and why.
During Ethos Self-Analysis, have students draft a short paragraph introducing themselves and their argument for a debate. They exchange paragraphs with a partner and provide feedback using: Does the introduction clearly establish credibility? What specific words or phrases help build trust? Are there at least two distinct methods of establishing ethos?
Extensions & Scaffolding
- Challenge: Ask students to find a current opinion piece, analyze its ethos strategy, and write a counter-argument that intentionally weakens the author’s credibility.
- Scaffolding: Provide a bank of ethos starters (e.g., 'I’ve seen this firsthand...' or 'Research shows...') for students to use in their self-analyses.
- Deeper exploration: Invite students to research a historical figure’s credibility strategies and present their findings as a mini-lesson to the class.
