Summary

Having received training in general education subjects, students often find it difficult to use their knowledge when studying special subjects. Integrated classes promote students|’ activity, development their professional thinking, and provide an opportunity for the synthesis of knowledge. Integrated classes arouse interest in the subject, relieve tension, uncertainty, and help the conscious assimilation of the material. Integration not only enriches the content of one subject with the content of another, but also combines them and provides comprehensive training, forming general and professional competence, interdisciplinary results. The use of integrated learning technology in the process of training students of secondary vocational education is one of the areas that implements the main goal of professional education: training a highly qualified, competent specialist who is able to think broadly and unconventionally, ready for self-development, self-education and self-improvement. The aim of this article is to show a concrete example of the realization of the integrated approach in the system of professional education.
