Emergent Leadership in Children's Cooperative Problem Solving Groups.

Social skills involved in leadership were examined in a problem-solving activity in which 252 Chinese 5th-graders worked in small groups on a spatial-reasoning puzzle. Results showed that students who engaged in peer-managed small-group discussions of stories prior to problem solving produced significantly better solutions and initiated significantly more effective leadership than control students. A mediation analysis suggested that it was because of effective leadership that groups who had experienced discussions achieved better problem solutions.
