The article discusses the general problems of using information technologies in physics and mathematics lessons in pedagogical universities and schools. The stages of the development of modern science are characterized by the interrelation of sciences. Therefore, the importance of interdisciplinary and intra-subject connections in the educational process becomes an urgent problem. They contribute to the systematization and deepening of students' and students' knowledge and the formation of skills of independent cognitive activity. Therefore, interdisciplinary and intra-subject connections are an important condition and result of an integrated approach in teaching and educating schoolchildren and students. The advantages and disadvantages of some educational programs in natural and mathematical disciplines based on information technologies and digital educational resources are analyzed, which make it possible to implement a competence-based approach in education in order to introduce interdisciplinary classes into the methodological foundations and diversify and integrate means of pedagogical influence on the student. This article emphasizes that the importance of using interdisciplinary connections in teaching physics is very high.

       The article also discusses the definition of interdisciplinary connections in the courses of physics, mathematics, computer science for deep assimilation of knowledge, theic approach, the unity of the material world, and the relationship of natural phenomena and society.
