The purpose of this article is to teach the student to solve problems of an applied nature that are of interest to the student. When using a subject-based learning system, interdisciplinary connections allow us to solve the existing contradictions between the disparate assimilation of knowledge and the need for their application, both holistic and complex, in the practical life of a person. As a result, knowledge becomes not only concrete, but also generalized, which gives students the opportunity to transfer this knowledge to new situations and apply it in practice. The article substantiates the need for interdisciplinary connections to reflect the integrity of nature in the content of educational material, to create a true system of knowledge and understanding of the world.
