Building a Persuasive Speech
This workshop brings the unit together. It moves from a position you hold to a delivered persuasive speech of two to three minutes. The aim is a case that is clear, honest and hard to dismiss.
The workshop at a glance

| 4. Structure | 10 minutes | Hook, claim, reasons, refutation, call. |
| 5. Rhetoric | 10 minutes | Two devices with a purpose. |
| 6. Draft | 15 minutes | A spoken-style draft. |
| 7. Mark and cut | 10 minutes | A marked script at target length. |
| 8. Rehearse and deliver | 15 minutes | Two timed runs and a short delivery. |
Step 1: Claim
A good claim is specific, contestable and relevant to the audience. It names the change, the scope and the direction.
| Topic | Too vague | Stronger claim |
|---|---|---|
| School food | “The canteen should be healthier.” | “The canteen should stop selling sugary drinks during school hours.” |
| Public transport | “Buses should be better.” | “The council should add a second bus on the 7.45 route.” |
| Environment | “We should protect nature.” | “The school should plant twenty shade trees on the eastern oval.” |
| Technology | “Phones are bad.” | “The school should ban phone use in classrooms, not at lunch.” |
Step 2: Audience
Identify what the audience already believes, what they value, what they fear and whom they trust. Choose the objections that matter most to them.
Step 3: Evidence
Find two or three credible sources. For each, write the claim it supports and the warrant. Check the original source, not just a summary.
| Claim | Evidence | Warrant |
|---|---|---|
Step 4: Structure
Use the persuasive frame: hook, claim, two or three reasons, refutation and call to action. Write one sentence for each before drafting.
Model skeleton: “A later start for Year 9”
Claim: Year 9 should start at 9am instead of 8.30am.
Hook: “By second period, half the class is awake. The other half is pretending.”
Reason 1: Adolescent sleep cycles shift later, so early starts cut sleep.
Reason 2: Sleep loss affects attention and mood.
Objection: “A later start would disrupt buses and family routines.”
Answer: “A pilot with one year level could test the change without disrupting the whole school.”
Call: “Ask the leadership team to trial a 9am start for Year 9 next term.”
This is an original teaching example, not a transcript of a real speech.
Step 5: Rhetoric
Choose two devices that serve the argument. A triad can organise the reasons; a contrast can sharpen the choice; a short anecdote can ground the claim. Mark them in the script and rehearse the delivery.
Step 6: Draft
Write for the ear. Use short sentences, active verbs and concrete examples. Read each sentence aloud. If you run out of breath, split it. If a term is unfamiliar, define it.
| Written | Spoken |
|---|---|
| “The implementation of the policy would require additional consultation.” | “We would need to talk to families before we change anything.” |
| “A significant proportion of students ...” | “Most students ...” |
| “It is therefore evident that ...” | “So the evidence points one way.” |
Step 7: Mark and cut
Mark breath points, stresses and pauses. Then cut ten per cent. Most first drafts contain throat-clearing, repeated reasons and one example too many. Removing them usually strengthens the case.
Step 8: Rehearse and deliver
- Read the speech aloud once without stopping.
- Time it at performance pace.
- Record one run and watch it with the delivery checklist.
- Ask a partner to state the strongest objection. Answer it aloud.
- Ask a listener to retell your case in one sentence.
- Choose one change and rehearse again.
- Deliver, take two questions and reflect.
Reflection
Write 100–200 words:
- What did you want the audience to accept or do?
- Which reason was strongest, and why?
- Where did the audience resist, and how did you respond?
- What changed between the first and final version?
- What would you do differently next time?
Planning template
| Element | Your notes |
|---|---|
| Claim | |
| Audience | |
| Hook | |
| Reason 1 + evidence | |
| Reason 2 + evidence | |
| Reason 3 + evidence | |
| Strongest objection | |
| Refutation | |
| Call to action |
Common errors
- Too many reasons. Two or three are enough.
- Evidence without a warrant. The audience cannot see why it matters.
- Rhetoric without purpose. Devices become noise.
- Straw-man refutation. The real objection remains unanswered.
- Vague call to action. The audience leaves without a next step.
- Reflecting only on delivery. Reflect on whether the case was persuasive.
