Many of the activities involve sharing with a partner or a small group. We use this technique in order to help the trainee get a different perspective about an idea or thought when verbalizing it or hearing it repeated from other people. The purpose of the sharing technique is to add dimensions - trying to help people "stretch" and get help and suggestions from one another.
It is the trainers/facilitators' responsibility to create an atmosphere of trust and non-judgement that will encourage people to feel free to express themselves. Early in the training process, the facilitator encourages people to share with each other. The facilitators talk about taking risks and explain new communication techniques of getting and giving feedback to each other - all ways of sharing.
