Inner & Outer Circle
Activate prior knowledgeInner & Outer Circle is a structure in which the group stands in two circles facing each other: everybody has exactly one partner right opposite them. For every question everyone first thinks in silence for twenty seconds, then all pairs talk at the same time, and on one signal the outer circle moves along one place: new partner, new question. Because every pair talks at once, every participant speaks in every round: across four rounds somebody tells their answer four times to four different listeners, and the answer gets sharper on the way. It fits open questions with many good answers, speaking practice, getting acquainted, and feedback rounds.

Goal
everybody talks, with somebody new each round
Two things to arrange in advance. An even number of participants: if you are one short, join in yourself or turn one place in the outer circle into a three. Somebody left standing every round drops out of the structure. And space: two circles need clear floor. If that will not fit, put two rows of chairs facing each other; the structure works exactly the same, with the outer row moving along instead of the circle.
Step-by-step instructions
4 steps
Form two circles · 2.5 minutes
Once, before the first question: count off. Ones make the inner circle, twos the outer one. The inner circle faces out, the outer circle faces in, and everyone stands opposite one partner. If the circles are already standing, set this step to 0 and it disappears.
Quiet thinking first · 20 seconds
Everyone reads the question silently and works out their answer. Do not look at your partner yet.
Talk with your partner · 70 seconds
Every pair talks at once. Each round the other circle starts: round 1 the inner one, round 2 the outer one. Halfway through the time you switch, so both talk for roughly as long. The screen says who starts this round. Follow up on one thing before the time runs out.
Outer circle moves on · 15 seconds
The inner circle stays put, the outer circle steps one place clockwise. Everyone is now facing a new partner.
Step 1 runs once, before the first round. Every question you enter becomes its own round with these three steps; without a question list you only set the number of rounds and give the topic out loud. The move is a step with its own timer: precisely the step that otherwise disappears.
Which learning strategy does the class train?
Activate prior knowledge
Students first pull up what they already know, before anything new is added. New material attaches to what is already there, so bringing it up first makes the new stick. Source: Wijze lessen (Surma et al., 2019), building block ‘activate prior knowledge’.
On the boardWhat do you already know? · First you pull up what you already know. New things stick better to something familiar.
Also trainable with this structure
- Explain in your own words · Four partners, four explanations: the fourth is shorter and sharper than the first.(natural sciences · maths & science)
- Retrieve from memory · One question about last lesson, and the material is back without you summarising it.(maths & science · natural sciences · language: grammar · language: vocabulary · text subjects · advisory)
Why does this work?
Inner & Outer Circle works because it multiplies speaking time: not one speaker for thirty listeners, but fifteen conversations at once. Three things do the work: the simultaneity, the silent twenty seconds, and the moving on itself.
In a class discussion there is one speaker and thirty listeners; whoever says nothing goes unnoticed. Here everybody talks every round, because in a pair there is nobody else to take over. That is simultaneity plus individual accountability, two of the principles Kagan builds his cooperative structures on: the speaking time comes from the structure, not from the student's willingness to speak up. The room is loud, and that is correct: the noise is the proof that everybody has the floor. Walk around and listen in without joining; the round is too short to stop anywhere for long.
Without thinking time every round starts with the half of the class that already has an answer while the other half is still reading the question. The classic wait time research has shown since the 1970s that a few extra seconds of thinking make answers noticeably richer, and here they do one more thing: working memory holds only a few things at once, so leave the question on the screen, otherwise part of that capacity goes into remembering the question instead of building the answer. Twenty seconds is the difference between two people talking and one person reading out their answer.
Moving on is not just variety. Somebody telling their answer for the third time tells it shorter, with a better example and without the run-up. You can hear it happen as you walk around. That is retrieval from memory with a different listener each time, and it is exactly why this structure delivers more than writing the answer down once. Moving on does a second thing too: it takes the choice away. Nobody picks their partner, so nobody is left over and nobody spends four rounds with the same friend.
When it fits, when to pick something else
When it fits
- For open questions with many good answers. "What do you find hardest about this topic?" produces thirty different answers, and everybody hears four of them, more than a class discussion delivers in the same time.
- To practise speaking. For modern languages and language support this is the densest format there is: four short conversations per student in ten minutes, each with a different partner and the same brief.
- As an introduction at the start of a course. Four rounds and everybody has spoken to four classmates they did not choose themselves. The circle does the work an ice-breaker usually has to force.
- For feedback rounds on their own work. Everybody takes their text, sketch or plan into the circle and explains it four times. The fourth explanation is the best one, and the feedback comes from four people instead of from you alone.
- As a warm-up before a class discussion. Everybody has said their opinion out loud once before the plenary starts. That removes the silence at the beginning, and the first speaker no longer has to be the bravest.
When to pick something else
- Not for questions with one right answer. A factual question is done in ten seconds and then the pair stands waiting for a minute. To retrieve knowledge with short, checkable questions, take the movement quiz: there everybody holds their own card with a question and its answer.
- Not to examine one question in depth. Seventy seconds per conversation is enough for an answer and one follow-up, not for an analysis. If you want the group to work one question through to the bottom, take the snowball: it builds the answer up from the individual to the pair to the four.
- Not in a room without floor space. Two circles need clear floor. If that will not work, put two rows of chairs facing each other: that is the same structure, with the outer row moving along. If even that is impossible, taking turns is the seated version: everybody gets the floor inside their own small group.
- Not with an odd number, without a plan. Join in yourself, or turn one place in the outer circle into a three that answers together. What you want to avoid is somebody being left over every round: that is not a small inconvenience but exactly the student this structure ought to be helping.
- Not for heavy personal topics. Here you tell the same story four times to four different people, and for a heavy topic that is a lot to ask. If you do want to discuss something personal, agree in advance that "pass" is allowed and keep it to one round, or take the snowball, where the step from your own answer to the group is gradual.

Frequently asked questions
What exactly is the Inner & Outer Circle structure?
A structure in which the group forms two circles: the inner one faces outward, the outer one faces inward, so everybody has exactly one partner opposite them. Every round runs three steps: twenty seconds of silent thinking about the question, roughly seventy seconds of conversation in which both speak, and then the outer circle moves one place clockwise on a single signal. After that comes the next question. Every question you prepare becomes its own round; prepare none and you set only the number of rounds and name the topic yourself.
How long does Inner & Outer Circle take?
With the default settings the whole structure takes ± 13 minutes: 4 rounds, briefing and look-back included.
One round takes about a minute and a half at the default times: 20 seconds of thinking, 70 seconds of conversation and 15 seconds of moving on. Four rounds are therefore some seven minutes, plus two and a half minutes to form the circles; the rest of the time above goes to the transitions between steps. With a longer question list it runs to a quarter of an hour and beyond. Whoever prepares the run sets the time per step; if the circles are already standing, set the first step to zero and it disappears.
How many participants do you need, and what about an odd number?
From about ten it becomes a real circle; up to roughly 36 it stays workable, because moving on does not take longer as the circle grows. You need an even number: every participant faces exactly one other. If you are one short there are two good solutions: join in yourself (you hear immediately how the conversations run), or turn one place in the outer circle into a three that answers together. What you want to avoid is one student left standing and waiting every round.
How many questions should I prepare?
One per round, and four rounds makes a good first run. Every line in the question field automatically becomes a round, so the length of your list sets the length of the structure. Good questions are open and have many good answers: "what do you find hardest about this topic?" works, "in which year was that?" does not, because it is done in ten seconds. If you have no list, leave the field empty: then you set only the number of rounds and name the topic out loud. No time? Under ‘Set up & start’ the AI writes them for you: choose ‘AI writes them’, give your topic and year group, and you get open questions, one per round, which you read through before you start. Prefer Microsoft Copilot? Ask: ‘Write 4 discussion questions about [topic] for students aged [age], meant for roughly a minute of talk per pair. Each has to be open, about the student’s own experience or opinion, and answerable without prior knowledge. One question per line, no numbering.’
What if there is no space for two circles?
Put two rows of chairs or tables facing each other. The structure does not change: one row stays seated, the other moves one place along after the signal, and the person at the end walks to the front. In a room with fixed rows you can also ask the front half of the class to turn around to the row behind them: pairs in two minutes with nobody having to walk. What you need is for everybody to sit opposite exactly one other person; what the arrangement looks like is secondary.
What is the difference from Movement Quiz?
Both put participants in changing pairs, but the changing works differently. Here the circles stand still and the outer one moves one place: that costs fifteen seconds, everybody always has a partner, and you need little space. In the movement quiz the class walks freely and finds a partner itself, and every student holds their own question card that changes owner after each conversation. Rule of thumb: one open question with a different partner each time? Take the circles. Many short questions with one right answer? Take the quiz.
What is the difference from Interview in Three Rounds?
Interview in three rounds works in fixed fours: A interviews B, then the other way round, and after that everybody tells the group what they heard from their partner, and that retelling is the heart of it, because it forces listening. Inner & Outer Circle has neither fixed groups nor a retelling step: the gain here is the number of different partners. If you want to force listening, take the interview; if you want speaking time and variety, take the circles.
How do you facilitate Inner & Outer Circle?
Three things carry it. One: the setting up. Count the class off in ones and twos, have the ones form a circle facing outward and the twos a circle around them facing inward. That is the most expensive minute of the structure, so do it properly once. Two: the signal. One clear sign, one place clockwise; "find somebody new" costs a minute and produces the same partners. Three: guarding the thinking time: twenty seconds of silence feel long if you do not count them down, but without that silence only the quickest talks in every pair. You yourself walk around and listen in without joining; what you hear is your starting point for the discussion afterwards.
Where does the structure come from?
It belongs to cooperative learning and is known in the literature as Inside-Outside Circle, described by Spencer Kagan; it rests on two principles that are clearly visible here: simultaneous participation (all pairs talk at once) and individual accountability (in a pair nobody can hide). In facilitation and team work the same arrangement returns as a format for structured dialogue. The silent thinking time goes back to Mary Budd Rowe's wait time research; why repeating to a new listener each time adds something, we checked against Uncommon Sense Teaching by Barbara Oakley, Beth Rogowsky and Terrence Sejnowski.
Everybody speaking: which structure fits?
| Structure | Goal | Group | Duration | When it fits |
|---|---|---|---|---|
| Inner & Outer Circle | the same question with a different partner each time | whole class | ± 13 min | open questions, speaking time for everyone |
| Movement Quiz | practise knowledge in changing pairs | whole class | ± 12 min | many short questions with one right answer |
| Interview in Three Rounds | interview each other and retell it | fours | ± 12 min | force listening in a fixed group |
| Taking Turns | everyone contributes in turn | 2–6 | ± 12 min | seated, no room to walk |
| Stand Up & Sit Down | show a position: agree or disagree | whole class | ± 9 min | a picture of the class in one second |
| Snowball (1-2-4-All) | gather and order ideas | 8–32 | ± 18 min | genuinely deepen one question |
