If we accept the view that teaching is one form of social interaction and highly a communication process, then it is possible to argue that different forms and kinds of social influence are established between a teacher and a pupil, and not only the influence of teacher on the pupil, but vice versa as well, the influence of pupil on the teacher. This paper emphasises the importance of social context in motivating the pupil by certain stimulative measures, which is substantiated by the results of the study performed in primary schools in Belgrade. The technique of systematic observation was applied and it comprised monitoring the classes of regular teaching and the frequency of stimulative measures in regular classes. The aim of research was to determine the significance of difference between the quality of communication between teachers and pupils and the frequency of stimulative measures. The quality of communication encompassed the course of verbal communication, expressing of initiative in class on the part of pupils, two kinds of pupils' responses and the possibility of combining those kinds and, finally, the dominant form of class work. The concluding part of the paper lists the basic steps that contribute to the quality of the communication between pupils and teachers.
