Think Aloud
Narrate your thinking as you model, so students hear the decisions they cannot see
Use this when
What is it?
Think Aloud is the practice of saying your thinking out loud as you model a task: the decisions, the checks, the wrong turns and the recoveries. Experts make most of these moves silently and automatically, so a clean demonstration lets students see the answer appear without the judgement that produced it. Narrating that judgement gives students the part of the method they cannot see, which is often the part they need.
The steps
- Choose one short stretch to narrate. Pick the part of the task where the real decisions are made. Two or three minutes of spoken thinking is usually enough; much longer than that and attention tends to fade.
- Give the class a listening job. Tell them what is about to happen and what they should listen for.You're going to hear me think. Don't copy anything yet. Just listen for the decisions I make.Without a frame, some students will copy the board while others simply wait for you to finish.
- Narrate in the first person. Use "I", and voice the thinking as it happens: the noticing, the choosing, the checking.I'm asking myself what this question actually wants. The word 'compare' tells me I need both poems in front of me before I write anything.If you hear yourself saying "so then you…", come back to "I".
- Narrate the checks as well as the moves. Students can already see what you write. Give them what they cannot see: why you are making this move now, and how you test it. For example:Before I move on, I'll read that line back and check it still answers the question.
- Include one genuine wrong turn. Start down a path this class might plausibly take, notice the problem aloud, and recover.Hmm. That gives me a negative length, which cannot be right. So one of my signs is wrong. I'll go back and check each line.Recovering calmly in front of the class shows students what to do when their own work goes wrong.
- Step out, then hand the thinking over. Mark the end of the narration clearly:That's my thinking. Amal, what did I check before I wrote anything?On the next problem, ask pairs to think aloud to each other while you listen in.
What it looks like
Mrs Cavanagh's class of 14-year-olds has an unseen poem on the board. "You're going to hear me think. Don't write anything. Just listen for my decisions." She reads the opening line. "I'm noticing 'hollow'. That's the second empty-sounding word in two lines, so I'm asking myself whether the poet keeps doing this."
Ryan calls out: "It's about grief, miss." "Hold on. This is my thinking time. Your turn comes next." She reads on, tries an idea, then stops. "Actually, that doesn't fit 'sings' at the end of the stanza. My first idea was too tidy. I'll keep both and read on." Ten minutes later, while circulating during paired think-alouds, she hears Ryan telling his partner: "I'm noticing… wait, that doesn't work with the last line."
How you’ll know it’s working
- During the narration, pens stay down and students watch you rather than the board. The room remains quiet enough for the thinking to be heard.
- Decision language begins to appear in student talk. Listening in on pairs, you hear "I noticed", "I checked", "that can't be right, so…".
- Count the recoveries: during paired think-alouds, tally how many pairs catch and fix a wrong turn out loud. Expect that tally to rise over three or four weeks.
- Independent work starts to carry the checks you modelled: answers read back and corrected mid-task, and crossed-out working with a fix underneath rather than an abandoned question.
Pitfalls & fixes
- Narrating everything. A running commentary buries the two decisions that matter beneath twenty that do not. Choose the judgements in advance and narrate only those.
- Slipping into "you". "So then you take out the common factor" has turned into instructions. Rehearse the opening minute before the lesson; saying "I'm asking myself…" brings the voice back.
- Staged, cartoonish errors. "Oops, silly me!" convinces nobody, least of all teenagers. Take the wrong turn from a mistake this class actually makes, and recover in the way you want them to.
- Talking while they copy. Students cannot transcribe and listen at the same time, so both halves suffer. Keep pens down during the narration; any copying can come afterwards.
Weigh it up
Why it’s worth it
- It teaches the part of expertise that a demonstration alone cannot reach: the noticing, choosing and checking that experts do silently. Students who only ever see finished work are left to guess at that process.
- It builds metacognition, students' ability to notice and steer their own thinking. The EEF's evidence review rates metacognitive approaches among the highest-impact, lowest-cost strategies it has examined, and hearing a teacher question themselves is many students' first model of how to do it.
- Handing the narration over turns it into a form of assessment. Listening to paired think-alouds surfaces misconceptions during the task, while there is still lesson time left to act on them.
- A narrated wrong turn, recovered calmly, is live evidence that mistakes can be worked through. It feeds the climate that Normalise the Struggle builds and makes wrong answers easier to offer.
- It requires no resources and no new lesson structure. It slots into the modelling you already do, in any subject and at any age.
The costs
- Recovering your own decisions is genuinely difficult, because expertise makes them automatic. The first few narrations need real preparation.
- It slows the demonstration down. A two-minute example may take five, and something else in the lesson has to give way.
- With a restless class, several minutes of uninterrupted teacher talk can lose the room. The listening job and the time limit are what hold the technique together.
Adaptations
- Early years / lower primary: keep it to a few seconds at a time and tie it to something visible: "I'm looking at the picture for a clue about this word." Children of this age copy the voice quickly, and many will begin muttering their own thinking as they work. Let them.
- Primary: give the narration a shared name, such as the thinking voice, and use it at predictable moments: a difficult word in the class novel, or the first step of a new calculation. "Thinking voice now. Hands down and listen."
- Secondary: teenagers tend to spot a staged error at once, so take your wrong turns from mistakes this class has actually made. Near exams, narrate exam decisions too: timing, question choice, and what you do when a question looks unfamiliar.
- Post-16 / adult: present it as professional practice: "This is how I read a source the first time I meet it." Adults who doubt their own ability often find it steadying to hear a specialist express uncertainty and work through it.
Where this comes from
Beth Davey codified the think-aloud in 1983 as a way of showing struggling readers what skilled readers do with a difficult text. Allan Collins, John Seely Brown and Susan Newman then made "making thinking visible" a pillar of cognitive apprenticeship, their account of how classrooms can borrow the way trades teach. The EEF's metacognition guidance now recommends that teachers model their own thinking when demonstrating new tasks. The format on this page (first person, kept short, one genuine wrong turn) is teacher craft and has not been trialled as a package.
