2.1About 70 minutes

Learning goals

I can choose a structure and language that fit my purpose and audience.
I can build labelled debate arguments using assertion, reasoning, evidence and impact.
I can defend my own work by acknowledging, answering, conceding and returning to my thesis.
I can answer interview questions with STAR and make a concise pitch with a specific ask.

Words to know

constructive speech
A debate speech that builds a side's case.

rebuttal speech
A debate speech that answers the other side's arguments.

A-R-E
Assertion, Reasoning, Evidence: a structure for a debate argument.

impact
Why an argument matters.

oral defence
A structured conversation in which you explain and defend your own project to an examiner.

behavioural question
An interview question about a past experience ("Tell me about a time...").

STAR
Situation, Task, Action, Result: a structure for behavioural answers, often with Reflection added.

pitch
A short talk presenting an idea and a specific request to a decision-maker.

Remember from Grade 11

In Grade 11 you spoke for a range of purposes: introducing and thanking guest speakers, performing a parody that kept the original's rhythm, leading a seminar on a literary analysis and moderating a panel. Grade 12 adds the speaking you'll do at the edge of high school and beyond: formal debate speeches, the oral defence of an independent study, interviews for jobs, programs and scholarships, and the short pitch. Each purpose calls for its own structure and its own language for its audience.

Let's start with one student, four audiences

In one week, Malik must:

Give a four-minute constructive speech in a debate tournament.
Defend his independent study on dystopian fiction in a ten-minute conversation with his teacher.
Answer questions in an interview for a part-time job at a hardware store.
Give a 30-second pitch asking the student council to fund a winter coat drive.

If he uses the same style for all four, something will go wrong. A debate speech that sounds like a pitch seems shallow; an interview answer that sounds like a debate speech seems combative. Purpose and audience decide the form.

Debate speeches: assertion, reasoning, evidence

Many Canadian school debate formats teach arguments in three parts, often called A-R-E:

Assertion: the claim, stated in one sentence and labelled ("Our first argument...").
Reasoning: why the claim is true; the logic.
Evidence: facts, examples or expert testimony that support the reasoning.

Strong debaters add an impact: why the argument matters. A constructive speech builds your side's case; a rebuttal speech answers the other side (using your flow sheet from the first lesson of this unit) and explains why your arguments still stand. The language is formal and direct: "Madam Speaker," "the Opposition claims," "we have shown."

Label each argument so the judge can flow it. The impact answers the question every judge silently asks: so what? (The evidence line is a model of the form, not a real statistic.)

The oral defence

In an oral defence, you explain and defend an independent project to an examiner (your teacher now; a committee, later, for a thesis). It isn't a speech: it's a structured conversation. Prepare:

A 60-second overview: your question, your thesis, your main evidence and what you concluded.
Anticipated questions, especially about weaknesses: Why these texts? What would someone who disagrees say? What would you do differently?
A pattern for hard questions: acknowledge the question, answer with evidence, concede what's fair, and return to your thesis. Conceding a real limitation shows mastery, not weakness.

Interviews and the STAR method

Many interviewers ask behavioural questions: "Tell me about a time when...". The STAR method gives answers a clear shape: Situation, Task, Action, Result. Many people add a final R for Reflection: what you learned.

The pitch

A pitch (sometimes called an elevator pitch) states, in 30 to 60 seconds, the problem, your idea, why it will work and exactly what you're asking for. It ends with a specific ask: "We're asking for $200 and a table in the front hall for two weeks in November."

Spend most of your answer on Action, using I rather than we, so the interviewer hears what you did.

Purpose	Audience	Structure	Language
Debate constructive	judge, opponents, audience	roadmap; labelled arguments (A-R-E + impact); summary	formal, direct, signposted
Oral defence	teacher or examiner	60-second overview; dialogue: acknowledge, answer, concede, return	academic; precise terms; hedged where honest (suggests, may)
Job or scholarship interview	interviewer	STAR (+ reflection) for each behavioural question	standard and professional, warm; I for your actions
Pitch	a decision-maker	problem, idea, why it works, specific ask	concise, concrete, confident

Each purpose has its own structure and register. Choosing the right one is part of the skill.

Worked example

Let's build a STAR answer

Interview question for a summer job at a day camp: "Tell me about a time you solved a problem as part of a team."

Background: in Grade 11, Sofia's group was building a model bridge for physics. Two days before the deadline, the bridge failed its load test. Sofia suggested splitting the group: two people redesigned the joints while she and another student rebuilt the deck. They retested the next day and it held twice the required load. She learned to divide work when time is short.

Situation (brief): "In Grade 11 physics, my group of four was building a model bridge, and two days before the deadline it failed its load test."
Task: "We had to find the problem and rebuild it in time."
Action (most of the answer, with I): "I suggested we split the work instead of all fixing the same part. Two of us redesigned the joints, where it had broken, while I rebuilt the deck with another student so the new joints would fit."
Result: "We retested the next day and the bridge held twice the required load."
Reflection, tied to the job: "I learned that when time is short, dividing the work clearly matters more than everyone helping everywhere. At camp, I'd use that when a plan falls apart and the group needs a quick fix."

A complete STAR answer of about 45 to 60 seconds: brief situation and task, a detailed action in the first person, a concrete result, and a reflection that connects the lesson to the job she's applying for.

Worked example

Let's answer a hard question in an oral defence

Malik's independent study argues that dystopian novels are really about the present, not the future. His teacher asks: "You only chose novels written in the last 30 years. Doesn't that weaken your claim about dystopias in general?"

Model a response using acknowledge, answer, concede, return.

Acknowledge: "That's a fair question, and I thought about it when I chose my texts."
Answer with evidence: "My focus was on how recent novels respond to their own time, so recent texts let me compare each book with the issues of the years it was written."
Concede what's fair: "You're right that I can't claim my conclusion holds for all dystopias. If I extended the study, I'd test it on an older novel to see whether it also answers its own present."
Return to the thesis: "So my claim is best stated about recent dystopian fiction, and within that group the evidence supports it."
Note the language: academic and precise ("extended the study," "best stated"), honest hedging ("I can't claim..."), calm and non-defensive.

Malik acknowledges the question, answers with his reasoning, concedes the limit honestly, and returns to a more precisely stated thesis. Narrowing a claim under questioning is a sign of mastery, and examiners usually reward it.

Know your opening and your ask

In every purpose, plan the first 15 seconds and the last sentence word for word. Debate: the roadmap and the summary. Defence: the 60-second overview. Interview: your first STAR sentence. Pitch: the problem and the ask. The middle can be flexible; the opening and the close should not be.

Hands-on activity

Four purposes in one evening

You need: a phone timer and one or two family members as your audience (and judges).

Pitch (30 s): pitch a real idea to your family (a weekend outing, a new chore system), ending with a specific ask.
STAR (60 s): have someone ask, "Tell me about a time you handled a challenge," and answer using STAR plus reflection.
Debate (2 min): argue one side of a light resolution, such as Be it resolved that board games are better than video games, with two labelled A-R-E arguments.
Defence (2 min): have someone ask you a tough question about a project or essay you've done; answer with acknowledge, answer, concede, return.
Ask your audience which purpose you handled best and which language sounded wrong for its purpose.

Just for fun

An elevator pitch is supposed to be short enough to deliver during an elevator ride.

In a three-storey high school, that's about ten seconds. Skip the introduction. Start with the ask.

Challenge

In a debate, your opponent says your evidence is outdated. Write a rebuttal response of three or four sentences that is formal and direct.

Compare the oral defence and the debate rebuttal: both answer challenges. How should the attitude and language differ, and why?

Write a STAR answer with reflection to "Tell us about a time you disagreed with someone and how you handled it," for a scholarship interview.

For parents and teachers

Big idea: ENG4U expectation 2.1 asks students to communicate orally for a range of purposes, using language appropriate for the intended audience. At Grade 12 these purposes include debate speeches, oral defences of independent work, interviews and pitches.

How to help at home:

Be the interviewer: ask two or three behavioural questions and listen for STAR.
Ask tough but kind questions about a project they've finished, so they can practise acknowledge-answer-concede-return.
Let them pitch you something real, and only say yes if the ask is specific.

Common difficulties:

Using one style for everything. Ask, "Who's listening, and what do they need?"
STAR answers that are all situation. Encourage more action and "I."
Getting defensive in a defence. Remind them that conceding a limit is a strength.
