Fishbowl is a participatory dynamic where a small group discusses a topic in the center of the space while others observe silently from the outside, fostering active listening, critical analysis and reflective participation in debate. Also known as inner-outer circle or conversation aquarium, this methodology promotes deep dialogue and conscious observation.
Preparation
- Define purpose and topic:
- Select a complex topic that merits multiple perspectives and deep debate.
- Establish the objective: explore different viewpoints, make decisions, analyze a problem or generate proposals.
- Determine if the fishbowl will be open (with rotating chairs) or closed (fixed group in center).
- Organize physical space:
- Place 4-6 chairs in a circle in the center of the space (inner circle).
- Arrange additional chairs in one or more concentric circles around it (outer circle).
- In open fishbowl, leave one empty chair in the inner circle for rotations.
- Ensure everyone in the outer circle can see and hear clearly.
- Prepare support materials:
- Guiding questions or case studies related to the topic.
- Sheets for observers to take notes.
- Timer to manage intervention times.
- Optional: recorder or graphic facilitator to document key ideas.
- For virtual modality:
- Use video call rooms with “bring on stage” function.
- Activate microphone only for those in the inner circle.
- Use chat for observers to register questions or comments.
Step-by-step instructions
- Introduction and framing
- Explain the methodology: who speaks, who observes, how rotations work.
- Present the central topic and guiding questions.
- Establish the rules: times, signals to rotate, active listening criteria.
- Formation of first inner circle
- Invite 4-6 volunteers to occupy the center chairs (or assign according to pedagogical criteria).
- The rest of the group sits in the outer circle as active observers.
- In open fishbowl, ensure there is always one empty chair for anyone wanting to participate.
- Dialogue start
- Facilitator launches the first question or poses the dilemma.
- Those in the inner circle begin to dialogue, exchange ideas and debate.
- Observers listen attentively, take notes, but don’t interrupt.
- Participant rotation (in open fishbowl)
- Any observer can stand up and occupy the empty chair to contribute an idea.
- When someone new enters, another participant from the inner circle must leave to maintain the number.
- This allows multiple voices to participate without saturating the conversation.
- Facilitation and deepening
- Facilitator can intervene to reformulate questions, ask for clarifications or introduce new angles of the topic.
- Manages times so conversation advances and doesn’t stagnate.
- Encourages different perspectives to be expressed.
- Fishbowl closure
- After 20-40 minutes, announce the closure of the fishbowl phase.
- Invite the last inner circle participants to synthesize key points.
- Plenary reflection
- Open space for everyone (including those who only observed) to share reflections.
- Ask: What did you learn by observing? What new perspectives emerged? What questions remain?
- Connect learnings with the group’s context or practical application.
