In the current sanitary and epidemiological situation and the total transition to a distance format of communication between the teacher and the student, the problem of maintaining the quality of the educational services provided at the proper level becomes especially urgent. One of the options for solving this problem is seen by the authors in a well-established feedback loop with students and a competent organization of pedagogical communication within the framework of e-learning. This article describes the experience of organizing distance communication in the classroom in the disciplines of the mathematical cycle with junior-year students of economic specialties, conducted using video conferencing, electronic information and educational environment and author's workbooks on the subject. The effectiveness of this method is confirmed by the results of checking the residual knowledge of students in mathematics, carried out when licensing their specialty.
