Modern education requires the development of new approaches to teaching aimed at the formation of a holistic scientific worldview in students. One such approach is to combine academic subjects such as physics and biology. These subjects, despite their indifference to each other, have many common foundations, which makes them ideal for conducting joint classes. This article provides methodological guidelines for the organization and conduct of integrated classes, and also shows the possibilities of interdisciplinary integration through the study of physical processes in biological systems. The main tasks of testing the model program of the elective academic discipline “fundamentals of biophysics” at the stage of general education at the profile level were determined by the authors: to demonstrate the possibility of interdisciplinary integration of two disciplines of the Natural Science cycle: physics and biology, to show students the unity of the laws of nature, the application of the laws of physics to a living organism. The methodological basis for teaching law at the General stage of education is considered to be a systematic-active approach that ensures the achievement of individual, subject-based educational results through the organization of active cognitive activity of students.
