Bulletin, This study aimed to make clear the effect of peer interaction observed in the collaborative kicking game task on its achievement. Totally 29 boy's and girl's pairs of 5 year-old nursery school children were required to collaborate and advise each other how to do well the motor-skill activity. The positive effect of peer interaction on the task achievement was observed only among children who gave the appropriate information each other especially on the direction of ball-kicking toward the target board and change it according to the responses of the advisee. The negative effect was shown among children whose advises became monotonous and stereotyped. These results were considered to suggest the helpful informationon child's motor-skill development, not only in peer interaction, but in teacher-child interaction.
