At the opening session participants are unknown to each other and can feel uncomfortable interacting and sharing personal experiences. In this situation it is good idea to introduce each other and express themselves in front of a group. This exercise gives an opportunity to the group to share their views and experiences, which makes the climate more comfortable. After this session, the trainer also needs to give a brief introduction on training design and course structure and the training conduction procedures. It helps the participants to adjust in a new situation and mentally prepare for learning.
