Abstract
The article outlines the main directions of conducting classes in STEM fields. The relevance is caused by the transition of school education to 12-year education. This need is to provide students with a deeper explanation of the connections of natural sciences in the education system and to develop their skills in the effective use of theoretical knowledge in practice. At the same time, the effective practical use of knowledge gained from science in various fields is today a very urgent problem for considering optimal ways to develop students' thinking skills.. The interest in studying this area is also due to the results of modern research. Therefore, special attention should be paid to strengthening the role of independent work of students in subjects in the secondary school curriculum, expanding the scope of their theoretical knowledge.
