Inner & Outer Circle

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.

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 — close to ten in total, and with a longer question list it runs towards a quarter of an hour. Whoever prepares the run sets the time per step; if the circles are already standing, set the first step to zero and it disappears.

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.

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 — 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.

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.

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.

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.

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.

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.
