摘要:This study investigated the influence of peer friendliness,conflict,and collaboration on children`s problem solving performance. Eighty-two preschool children (41 pairs) filled out the Friendship Assessment Inventory and participated in 3 problem-solving sessions using the Tower of Hanoi. Results showed that just working together does not improve children`s problem solving performance. The degree of friendliness children have for each other has a significant effect on their problem solving performance. The children who worked with more friendly peers were more collaborative and were better problem solvers than those who worked with less friendly peers. This study suggests the importance of the relationship between interacting peers on problem solving performance.
