What is the 1-2-All technique?
The 1-2-All is a facilitation technique that allows larger groups to generate questions, suggestions, and solutions all at the same time, making sure all participants have an opportunity to contribute.
The meeting leader poses a question, then asks each participant to consider the answer silently on their own. The group then breaks into pairs to discuss the topic, and perhaps then foursomes. Finally, the discussion moves to the entire group.
This technique is also known as Think-Pair-Share (TPS) and 1-2-4-All
