Debate Tutoring Guide: Motions, Reasoning Chains and Rebuttal

Debate starts with one motion read word by word and one argument built from the 4 parts of AREL: assertion, reasoning, evidence, and a link back to the motion. On that base, learners train rebuttal, Points of Information, impact weighing, and speeches in 3 competition formats: Asian Parliamentary, British Parliamentary, and World Schools.

A debater's toolkit

Five debate skills that grow round after round

Each one rests on the last: a solid single argument feeds rebuttal, and sharp rebuttal feeds team strategy.

Unpacking the motion

Learners mark the key terms, write a fair definition, and set out the burden, meaning what their side must prove for the motion to stand. Practice uses motions from real tournaments on a rotating range of themes. Every definition faces one simple test: does the other side still have reasonable ground to argue on? If the answer is no, the definition gets rewritten before the first argument is drafted.

Structured arguments with AREL

A clear assertion, cause-and-effect reasoning, relevant evidence, and a link to the motion follow a fixed order, so judges can track every point inside a tight speaking time. Each argument gets a short label that teammates and judges can refer back to. Learners get used to delivering one complete argument in about a minute, then checking which of the four parts came out thinnest.

Rebuttal and Points of Information

Learners practise finding the weakest link in the other side's reasoning, using mitigation, even-if, and turn, and handling interruptions without losing composure. Paired drills have learners offer and answer POIs in turn. Counterarguments to their own case are prepared during prep as well, so an attack in the round feels like something they have already met once.

Matter, manner, and method

Adjudicators weigh content, delivery, and speech structure all at once. All three are trained through recorded speeches that are replayed and checked item by item: voice clarity, pace, eye contact, signposting, and how time is split across the speech. Notes from the first recording become the benchmark for the next, which makes even small changes easy to see.

Strategy for each format

The number of teams, the number of speakers, the speaking order, and the job of each position all change between Asian Parliamentary, British Parliamentary, and World Schools. Debaters learn to adjust how they split arguments, how they close, and how they weigh clashes to suit the format ahead. Full practice rounds under real timing help them settle into each format's rhythm before a tournament.

The full guide

Debate tutoring guide: from the first motion to the closing speech

The nine parts below follow the order a debater meets things inside a round, from reading the motion to weighing the clashes in the final speech.

Three kinds of motion: believes, would, and regrets

Every debate round begins with a single sentence called the motion, and its opening words already signal the kind of work ahead. A "This House Believes That" motion asks a team to prove that a statement is true or worth holding. A "This House Would" motion asks the government side to carry out a policy, which brings a duty to explain how that policy would actually work. A "This House Regrets" motion asks teams to compare the world as it is with a world in which some event or trend never happened. Learners who can spot these three openings know from the first second where their case needs to point.

Once the type is clear, the next step is definition and burden. The definition sets out what the key terms mean in a way that is fair, so the opposing team still has room to debate. The burden is the list of things that must be proven for the motion to stand. On a motion banning fast food advertising during children's viewing hours, the government side has to show that the problem is real and that the ban genuinely reduces it. A definition squeezed so tight that the other side has nothing left to argue is known as a squirrel, and judges usually penalise it.

The drill is straightforward. Learners take a motion, write down its type, underline loaded words such as "ban", "must", or "should", and then write the definition and burden at the very top of the prep sheet. The exercise is repeated with motions on changing themes, from education and health to technology, until learners can finish it within a few minutes without hesitating.

The opening words of a motion decide the type of burden, so identify the form before writing a single argument.

The R in AREL: the cause-and-effect chain beginners skip

Within AREL, the R for Reasoning carries the heaviest load and is the part most often skipped. Beginners tend to write a claim and then attach evidence straight away, as though the judge will fill in the explanation between them. Stephen Toulmin, in The Uses of Argument (1958), called this part the warrant: the bridge that explains why a given piece of evidence supports a given claim. Without that bridge, an argument sounds like two sentences that just happen to sit next to each other.

The way to train it is to break reasoning into three or four links. For the claim that an advertising ban protects children's health, the chain might run like this: children are not yet able to filter persuasive advertising, frequent ads make food high in sugar and salt feel normal, overconsumption raises the risk of nutrition problems, and limiting exposure to ads cuts that chain at its start. Each link can be attacked by the other side, so each link also needs to be defensible on its own.

A common drill at this stage is the "chain of whys". The learner reads out the claim, a practice partner asks "why?" after each sentence, and the learner answers with the next sentence. As soon as the answers start circling or repeating the original claim, that is where the reasoning breaks and needs repairing. Connecting words such as "so" and "as a result" get checked one by one too: does the jump from the previous sentence make sense to a listener who does not yet agree?

Chains that run too long cause trouble of their own, because judges lose the thread by the fifth or sixth link. Three or four steps, each one clear, are usually enough for a single argument inside a speech of around seven minutes.

A strong argument can answer "why" at every link of its chain without falling back on the original claim.

An example bank for impromptu motions

Many tournaments use impromptu motions, which are announced shortly before the round. The national preliminary rounds of LDBI, Indonesia's school debating championship in the Indonesian language, run five rounds on impromptu motions, and online research during prep is not allowed. In rounds like these, the evidence a debater uses is whatever they stored in memory well beforehand.

An example bank is built through regular reading. Learners keep notes on current issues by theme, such as health, education, environment, economy, technology, and international relations. For each issue they write three things: what happened, who is affected, and which figures or cases can be quoted safely. Notes stay short so they are easy to review. In a speech, a source only needs a brief mention, along the lines of "according to health ministry data", because speaking time is too valuable for long quotations.

The bank also has to stay honest. Any figure that seems doubtful is better removed from the notes, since invented evidence that an opponent or judge catches undermines trust in the whole speech. When firm data is not available, a debater can still draw on a case study, an apt analogy, or widely accepted reasoning, as long as the link to the claim is spelled out clearly.

Testing the bank is practical: pick a random motion from an old tournament list, allow a short prep time, and see whether the learner can fill the evidence column for two claims from memory alone. Any empty column shows which theme the bank still needs to cover.

Preparation for impromptu motions happens weeks before the tournament, through issue notes that are read and reviewed regularly.

Splitting the case between first, second, and third speakers

Parliamentary debate is a team event, and a team's strength depends heavily on how it divides the work. In Asian Parliamentary, each side has three speakers. The first speaker opens with the definition, burden, and an outline of the case, then delivers the first argument. The second speaker rebuts the opposing speaker who went before and then brings the next argument. The third speaker spends nearly all of their time on rebuttal and on reinforcing the main clashes.

Dividing arguments between speakers is called the split. A good split separates arguments by angle, for example one speaker taking the principled side and another the practical side, so no two speakers cover the same ground. A weak split shows when the second speaker turns out to be re-explaining the first speaker's argument in different words. Judges read that as a thin case.

Another part of teamwork is the model and the characterisation of stakeholders. On a policy motion, the government side sets out the model: who runs the policy, how it is carried out, and what happens to those who break it. Characterisation describes who is affected and how they are likely to respond. Learners practise writing both in a few short sentences, because a convoluted model eats up speaking time that belongs to the arguments.

A useful drill here is three-person prep with rotating roles, so every learner sits in the first, second, and third speaker's chair at some point and feels the demands of each position for themselves.

A healthy split gives every speaker their own angle, so the team's case grows deeper with each speech.

Rebuttal techniques: attacking a link, mitigation, even-if, and turn

Rebuttal comes in several techniques that can be practised separately. The first is attacking a link: the debater points to one step in the opponent's reasoning where the jump does not hold and explains why that step fails. This works best when aimed at reasoning or evidence, the two parts of an argument that most often crack.

The second technique is mitigation. The debater accepts that the harm the other side describes may exist, then shows that it is small, rare, or solvable by other means. The third is even-if, which follows the pattern "even if the other side is right, our side is still better because ...". It earns its place when a debater is unsure of fully knocking down an argument, since it provides a second line of defence.

The fourth technique is the turn, which flips the opponent's argument so that it ends up supporting your own side. If the opposition says an advertising ban hurts small businesses, a government speaker can show that small businesses are the ones least able to compete with the ad budgets of large companies, so the ban actually opens space for them. A turn carries risk, because it has to be explained carefully so that the team does not appear to contradict itself.

The drill uses a recording or transcript of one opposing speech. Learners write a rebuttal for each of its arguments using a different technique each time, then choose the strongest to deliver. A rebuttal that only repeats one's own claim more loudly is marked as unfinished.

Convincing rebuttal pinpoints exactly where the other side goes wrong, then offers competing reasoning.

Points of Information and protected time

Points of Information, or POIs, are brief interruptions offered by the opposing side during a speech. In parliamentary formats, POIs may only be offered outside the first and last minute of a speech, two windows known as protected time. The speaker holding the floor may accept or decline, and at many tournaments a speaker is expected to take one or two POIs per speech.

Offering a good POI means preparing a short question or statement, roughly fifteen seconds long, aimed at a weak spot in the other side's case. POIs that run long usually get cut off, and POIs that ask about trivial details waste the opportunity. Learners are trained to jot down possible POIs while they listen, so that when they stand, the sentence is ready to go.

Answering a POI calls for composure. The speaker listens to the end, answers in one or two sentences that tie the response back to their own case, and returns to the speech structure without losing their place. Nerves show up most at this moment, especially when a POI arrives in a pressing tone.

Paired drills build both sides of this skill. One learner speaks for a few minutes, the partner offers POIs at legitimate moments, and then they swap roles. The skill is taking shape once a speaker can accept an interruption and move on to the next signpost without a long pause.

A good POI is short and well aimed, and a good answer always leads back to your own case.

Weighing and the closing speech: judging the clashes at the end of a round

Every round produces a handful of clashes, the points where the two sides directly contradict each other. Advanced debaters learn to name those clashes openly, for example "the first clash is whether this ban works, the second is who is harmed most". Naming them like this helps judges follow the flow and file every argument in the right place.

Weighing is the skill of showing why the impacts on your side matter more than the impacts on the other side. Common yardsticks include scale (how many people are affected), probability (how likely the impact is), severity, the vulnerability of those affected, and whether the harm can be reversed. A debater who weighs hands the judge a reason to decide. A debater who only piles up arguments leaves the weighing to the judge.

Weighing is most visible in the closing speech. Asian Parliamentary and World Schools both have a reply speech given by the first or second speaker, while in British Parliamentary the summarising job falls to the second speaker of each closing team, known as the whip. This speech sums up the clashes and explains why its side comes out ahead on each one, without introducing new arguments.

The drill is to watch a recording of a tournament final, list its clashes, and then draft a closing speech in three columns: the clash, our position, and why we win it.

Weighing impacts gives judges a clear reason to choose your side on every clash.

Matter, manner, and method on the adjudicator's score sheet

Adjudicators in parliamentary debating typically assess three things: matter (the content of arguments and evidence), manner (how it is delivered), and method (speech structure and strategy). The LDBI and NSDC guidelines and World Schools use equivalent terms, content, style, and strategy, weighted 40, 40, and 20. Understanding how a judge reads a speech helps learners see which part to work on first.

Manner covers voice clarity, pace, eye contact, and body language at the podium. Debaters who speed up when nervous often lose the judge's attention even when the content is strong. Signposting, which means announcing at the start what will be covered and then marking each move to a new part, belongs to method, and it makes a speech far easier to take notes on.

Practice here relies on recordings. Learners record a speech, play it back, and work through a checklist: can the signposts be heard, does the time split match the plan, are there unnecessary pauses, and is eye contact spread across the whole room? The check is done for every speech, because small changes such as slowing down the closing line show up clearly from one recording to the next.

At advanced levels, learners also practise adjudicating: watching a round, deciding the winner, and writing up the reasons for the decision. This teaches them how judges weigh a round, and that understanding comes with them when they step back up to the podium.

Recorded speeches checked against the same list every time let learners measure their own progress in manner and method.

Moving between formats: Asian Parliamentary, British Parliamentary, World Schools

Asian Parliamentary sets two teams of three against each other, government and opposition, with speeches of around seven minutes per speaker plus reply speeches. It is widely used in school-level competitions, including the Indonesian-language LDBI, so it is often the first format that secondary students learn.

British Parliamentary brings together four teams of two: Opening Government, Opening Opposition, Closing Government, and Closing Opposition. Speeches last seven minutes and prep time is usually fifteen minutes. It is the format of the university circuit, including NUDC and WUDC. Its signature challenge sits with the closing teams, who must bring an extension, a fresh line of analysis that sets them apart from the opening team on the same side. University students coming from Asian Parliamentary often run short of material in this position.

World Schools pits two teams of three speakers against each other, with eight-minute substantive speeches and four-minute reply speeches. Motions come in two kinds, prepared motions released well in advance and impromptu motions, so debaters need two ways of getting ready.

Since the argument skills underneath stay the same, moving to a new format is mostly a matter of learning the speaking order, each position's job, and how rounds are won in that format. Learners usually write the order and roles on a single sheet, then run several practice rounds in the new format before a tournament.

AREL, rebuttal, and weighing carry across all three formats; what changes is the speaking order and each position's job.

Common questions

Questions about learning debate

What do learners cover first in debate tutoring?

Early sessions usually focus on reading a motion and building one complete argument with the AREL framework. Learners practise recognising the type of motion, writing a definition and burden, and then filling in the assertion, reasoning, evidence, and link for a single argument. Once that feels smooth, the work moves on to speaker roles and basic rebuttal. Early practice motions tend to come from issues close to the learner's daily life, such as school, campus, or social media, so attention stays on argument structure.

Which debate format should I learn first?

Let the competition you are aiming for decide. School tournaments often run Asian Parliamentary or World Schools, while the university circuit mostly uses British Parliamentary. For beginners without a set tournament, Asian Parliamentary is a common starting point because the three-against-three layout is easy to grasp. The core argument skills are shared by all three, so switching formats comes down to learning the speaking order, each position's job, and running a few practice rounds in the new format.

Can debate be learned in Indonesian as well as English?

Yes. Indonesian-language debating has its own competition track, such as LDBI for senior high school students, while English-language debating is used at NSDC, NUDC, and on the international circuit. Argument structure, rebuttal techniques, and impact weighing work the same way in both languages. The differences lie in vocabulary, the official terms each competition uses, and the reading sources behind an example bank. Learners who need both usually strengthen argument structure first and then adapt the language.

How many arguments should one speaker bring?

Two or three complete arguments are usually stronger than five half-built ones. Speaking time in parliamentary formats runs from seven to eight minutes, and part of that goes to rebuttal and answering POIs. Each argument needs room for its assertion, reasoning, evidence, and link to the motion. Judges reward completeness, so learners are trained to pick their strongest arguments during prep and keep the rest in reserve as material for rebuttal.

How can a speaker stay calm when taking a POI?

Nerves about being interrupted usually fade with repetition. Learners practise with a partner who offers POIs at legitimate moments, starting with gentle interruptions and building up to pressing ones. The answer follows a fixed pattern: listen to the end, reply in one or two sentences that connect to your own case, and return to the next signpost. Keeping a brief outline of the speech on a card also helps, since the speaker knows exactly where to pick up again.

What is an extension in British Parliamentary?

An extension is the new contribution that each closing team, Closing Government and Closing Opposition, is expected to bring. Because a closing team shares a side with an opening team, it has to show analysis the opening team has not touched yet: another stakeholder's angle, a deeper mechanism, or sharper weighing. An extension that simply repeats the opening team makes a high ranking hard to reach. The drill is to listen to an opening speech and write a new angle within a short time.

From what age can someone start learning debate?

Debate can be learned from about age 8 through mini-debates, practice in voicing opinions, and argument games on familiar topics. At that age the focus is on the confidence to speak and on telling facts, opinions, and assumptions apart. Secondary students move into speaker roles and competition formats, university students into British Parliamentary, and adult learners usually apply the argument framework to meetings and presentations. There is no upper age limit for getting started.
