For almost eight months of leading the two TGGs, the co-researchers made use of various effective group skills in leading the groups and enhancing group interactions, group-openness, trustfulness, and discussion atmosphere. In the meantime, in order to achieve the group goals and satisfy the group members'' needs, we developed six models of operation suitable for TGG. Besides, we also found that TGGs might not be able to avoid some negative group dynamics, although they could develop some positive group dynamics.
