The purpose of the study was to investigate the influence of the subject-subject interaction of a teacher with a group of junior teenagers on the change of its sociometric structure in the process of learning. We analyzed the state-of-art in the investigations of sociopsychological processes in a study group using the sociometric method; the study also revealed features of the group structure and the dynamics of its change. The relevance of the work is due to the lack of knowledge of how to form an educational group as a collective subject and its role in the learning success.
