It is well-known that communication is the main source and necessity of human development and activity. It promotes social relationships, self-image and a wide range of cognitive and non-cognitive skills. Preschoolers communicate both with their peers and adults. It is traditionally assumed that peer communication greatly depends on the teacher-child interaction, leading role of the adult, and the child's own activity, which are the main elements of the Russian preprimary education system.Changes in social situations, reductions in available play time, greater engagement of children in activities and many other factors can affect modern preschoolers' peer communication. Therefore, the effect of teacher-directed and child-directed teacherchild interactions on preschoolers' peer communication important to study.The following methods were applied: peer-communication observation, the behavioral tests 'Magic room' and 'Mosaic' , and the sociometric procedure 'Two houses' . The sample included 49 Moscow preprimary students aged 4 to 6 year old (25 girls and 24 boys).The research proved that preschoolers showed better results in child-directed interactions, such as playing skills, compared with a similar situation in which the children were directed by the teachers. Additionally, the level of proactiveness, communication success, conflict resolution, prosocial behavior and emotional response to peer influence did not differ among children.Thus, the child-directed approach is more beneficial to preschoolers' communication development than a teacher-directed approach.
