Oral Communication
Develop your skills in debate, class discussion, and formal presentations — speak with confidence, clarity, and purpose.
Delivering a Formal Presentation
A formal presentation communicates information or an argument to an audience in a structured, rehearsed, and professional way. At Year 8, you are expected to speak fluently, maintain eye contact, and use vocal variety to keep your audience engaged.
Verbal Techniques
- Pace: Slow down for emphasis; speed up to show excitement.
- Pause: A deliberate pause commands attention.
- Volume: Project to the back of the room.
- Tone: Match your tone to your message (serious, persuasive).
Non-Verbal Techniques
- Eye contact: Scan the room, don't read from notes.
- Posture: Stand straight to project confidence.
- Gestures: Use natural hand movements to emphasise points.
- Facial expression: Reflect the emotion of your content.
Debate Structure
A formal debate involves two teams — affirmative (agrees with the topic) and negative (disagrees) — presenting structured arguments in front of an adjudicator. Each speaker has a specific role.
| Speaker | Role | Key task |
|---|---|---|
| 1st Speaker (Aff) | Define and begin | Define the topic and present the team's case. |
| 1st Speaker (Neg) | Rebut and begin | Rebut the affirmative, define differently if needed, and present the negative case. |
| 2nd Speakers | Develop and rebut | Develop the team's arguments and rebut the opposition's points. |
| 3rd Speakers | Summarise and rebut | Summarise the whole debate and explain why their team has won. |
The TEEL structure for debate points
Topic sentence, Elaboration, Evidence, Link — each point in a debate speech should follow this structure for maximum clarity and persuasive force.
Contributing Effectively to Discussion
Class discussions and seminars require different skills from formal presentations. Here, you must listen actively, respond to others, and build on ideas rather than just delivering a pre-prepared speech.
Useful sentence starters for discussion:
- "Building on what [Name] said..."
- "I agree with the point about X, however..."
- "Could you clarify what you mean by...?"
- "I'd like to add that..."
- "I respectfully disagree because..."
Do
- Listen without interrupting.
- Refer to others' ideas specifically.
- Support your points with examples.
- Keep contributions focused and concise.
Avoid
- Dominating by speaking too long.
- Dismissing others' ideas rudely.
- Going off-topic.
- Repeated "I think" without evidence.
Key Vocabulary
Rebuttal
A direct response to an opponent's argument, pointing out why it is flawed or insufficient.
Vocal Variety
Deliberate variation of pace, volume, pitch, and tone during a speech to maintain audience engagement.
Affirmative
The debate team that agrees with the topic as stated, arguing in its favour.
Active Listening
Fully concentrating on what another person says — processing, questioning, and responding thoughtfully rather than simply waiting your turn to speak.
Worked Examples
Evaluate this rebuttal: "That's wrong. Our side is obviously right."
Problems: No specific reference to the opponent's argument. No evidence provided. "Obviously" is a weak assertion.
Improved rebuttal: "The opposition claimed that uniforms restrict individual expression. However, research by the Australian Institute of Teaching (2024) shows that uniform schools report higher levels of student belonging — suggesting that the shared identity actually supports wellbeing, which we argue is more important than individual fashion choices."
How can you use pausing effectively in a speech?
Before an important point: Pause to signal "pay attention". The silence creates anticipation.
After a rhetorical question: "How many of us have felt invisible? [pause] More than you think." The pause gives the audience time to actually consider the question.
After a key statistic: Let the number land. "Two children die in Australian road accidents every week. [pause] Two."
How do you respond to a classmate's idea in a discussion without dismissing them?
Weak response: "That's not right. It doesn't make sense."
Strong response: "That's an interesting point about social media helping people connect — I can see why that matters. I'd add, though, that connection can happen without the harmful algorithms that are designed to keep us scrolling. I think we need to separate connection from the platform itself."
What makes it strong: Acknowledges the idea, extends it thoughtfully, and disagrees with specific reasoning rather than personal dismissal.

Key Concepts Summary
- ●Use vocal variety (pace, pause, volume, tone) and non-verbal cues (eye contact, posture, gesture) to engage your audience.
- ●In debate, the affirmative supports the topic and the negative opposes it — each speaker has a specific structured role.
- ●A strong rebuttal specifically addresses the opponent's point and counters it with evidence.
- ●In discussion, active listening — referring specifically to others' ideas — is just as valued as speaking confidently.
- ●Use TEEL (Topic, Elaboration, Evidence, Link) to structure each point in your debate speech or class discussion contribution.
