The effectiveness and quality of a teacher's work depends on many factors, among which his methodological preparation is of great importance. This is due to the fact that it is the methodological activity of the teacher that has direct access to students, to the organization of their educational activities, to the design of the educational process. In addition, in the process of methodological training, those skills are formed and implemented that contain the knowledge acquired by students in the psychological-pedagogical and special (in particular, mathematical) courses.
