How to practice a 3-minute thesis (3MT) presentation

What the 3MT asks of you on the day

The rules are short, and they shape how you should practise. Under the official 3MT rules from the University of Queensland, which started the competition, you get three minutes at most and going over means disqualification. You may show a single static slide, with no transitions or animation, from the start of your talk. No sound or video files, no props. The talk has to be spoken word, and the clock starts as soon as you move or speak.

You also give it without a teleprompter or slide notes on screen. Notes are handled differently by different universities: some heats ban them outright, and some allow a cue card but discourage it. Check your own heat's rules, and plan to present without notes, because that is the version you need to be ready for.

The judging criteria have two headings: comprehension and content, and engagement and communication. In plain terms, judges want to hear why your research matters, what you did, what you found and what it changes, in language a non-specialist follows, delivered with real enthusiasm, with a slide that adds something.

Step 1: Write for the ear, to a word budget

• Aim for roughly 300 to 380 words. At a typical presenting pace of about 130 words per minute, 390 words fills the whole three minutes and leaves no room for pauses. Paste your draft into the talk length calculator to see where you stand.
• Follow a simple arc. A problem a stranger cares about, what you are doing about it, what you have found or expect to find, and why it matters beyond your lab.
• Swap jargon for the picture behind it. If a technical term has to stay, define it in a few words the first time you use it.
• Write numbers the way you say them. "About one in five" is easier to hear than "21.4 percent".

Step 2: Read it aloud before you memorise anything

Read the draft out loud with a timer, standing up. Mark every place you stumble: those sentences are too long, too dense or hard to say. Rewrite them and read again. Keep going until three reads in a row land between about 2:40 and 2:50. That margin matters. A slow start, a laugh from the audience or a moment of nerves can each take a few seconds, and over three minutes there is no slack.

Step 3: Rehearse in stages

1. With the script in front of you. Out loud, standing, at full voice. The goal is for the words to start sounding like yours.
2. With key phrases only. Keep the first sentence of each part of the arc and let the rest come from memory.
3. With nothing. Record yourself on your phone and listen back once a day. You will hear the rushed sentences straight away.
4. To someone outside your field. Afterwards, ask them to tell you what your research is about. If they can't, fix the content before you polish the delivery.
5. In a practice heat. If your graduate school runs a workshop or a mock round, take it. Presenting to a room is different from presenting to your desk.

Step 4: Practise the parts people forget

• The first ten seconds. The clock starts with your first movement, so walk on, settle, make eye contact and then begin.
• The final line. Have one closing sentence you could say even if the middle went wrong. It is what the judges hear last.
• Recovery. Practise losing your place on purpose: stop mid-sentence, breathe, and pick up from the start of the next part. A smooth recovery costs a few seconds; freezing can cost the talk.
• Pace. Nerves push most people faster. If a practice run comes in well under your usual time, you rushed.

Step 5: Build the slide last

Once the words work, design the one slide to support them: a single clear image or diagram, a short title, and as little text as you can manage, readable from the back of the room. Ask yourself whether someone who heard your talk would understand the slide better afterwards. If yes, it is doing its job.

Rehearse your 3MT with Aitho

Aitho is for practice here, not for the stage. The 3MT allows one static slide and no props, and many heats do not allow notes, so the event's rules apply on the day.

During the weeks of practice it helps with stages 1 and 2. Import your slide as a PDF or PowerPoint, paste your script, and read it out loud. The script follows your voice, so you can rehearse standing up without holding a page or scrolling. If you pause, it waits; if you skip a sentence, it catches up, which shows you exactly where your memory drops lines. Keep a timer running beside it. The steps are on the rehearse out loud card, and adding your script takes a minute.

Questions

How many words should a 3-minute thesis be?

Roughly 300 to 380 words. At about 130 words per minute, 390 words fills all three minutes, so most presenters write shorter to leave room for pauses. Time yourself reading aloud to find your own pace.

Can I use notes in a 3MT?

It depends on your heat. The official rules allow one static slide and no props; some universities ban notes outright and others allow a cue card but discourage it. Plan to present without notes and check your local rules.

How should I practise a 3MT in the last week?

Rehearse out loud every day, without the script, with a timer, until several runs in a row land under 2:50. Short daily rehearsals give you more chances to find weak lines than one long session the night before.

Can I use Aitho during the 3MT itself?

No. Use Aitho to practise. The 3MT allows one static slide and no props, and the event rules apply on the day.
