3-2-1 Bridge
The 3-2-1 Bridge is a thinking routine that encourages participants to reflect on their initial understanding of a topic, identify key takeaways after new information is presented, and then bridge the gap between their initial and evolving understanding. It helps individuals make connections and deepen their comprehension of complex concepts.
When to use 3-2-1 Bridge
Use this method when introducing a new concept or idea, after a presentation, or after a group discussion to help participants synthesize information and connect it to their prior knowledge.
What it solves
Superficial understanding of complex topics; difficulty connecting new information to existing knowledge; passive listening during presentations.
How to run 3-2-1 Bridge, step by step
- Initial Thoughts (5 min): Ask participants to individually write down 3 thoughts, 2 questions, and 1 metaphor/analogy related to the topic *before* any new information is presented.
- Presentation/Discussion (Time Varies): Present the new information or facilitate a discussion.
- Key Takeaways (10 min): After the presentation/discussion, have participants individually write down 3 new pieces of information they learned, 2 interesting things they noticed, and 1 connection they made to their initial thoughts.
- Bridge (5 min): Ask participants to reflect on how their thinking has changed and write down a 'bridge' statement that connects their initial thoughts to their new understanding.
- Share (Optional, 5-10 min): Invite participants to share their bridge statements with the group.
Materials needed
- Paper or digital document
- Pens or keyboards
- Timer
Facilitator tips
- Emphasize that there are no right or wrong answers during the initial thoughts phase.
- Encourage participants to be specific and provide examples in their reflections.
- Model the process by sharing your own 3-2-1 Bridge example.
Common pitfalls
- Participants struggle to connect their initial thoughts to the new information. - Provide guiding questions to help them make connections.
- Participants simply repeat information from the presentation without reflecting. - Encourage them to think critically and synthesize the information in their own words.
Variations
- Use images or videos instead of text-based information.
- Have participants share their reflections in small groups before sharing with the whole group.
- Adapt the number of thoughts, questions, and connections based on the complexity of the topic.
Running it online or hybrid
Use a shared online document or whiteboard tool like Miro or Google Jamboard for participants to record their thoughts.
What it produces
Individual reflections recorded in a 3-2-1 format showing initial thoughts, key takeaways, and connections made.
