Abstract
<jats:p>The chapter is devoted to the application of one of the most relevant and in-demand biology teaching technologies in school – case study. Biology as an academic subject has great potential for the implementation of various forms of educational organization. FGOS SOE sets a number of difficult tasks for biology, one of which is to organize the educational process in such a way that it is as effective as possible and brings real results, but at the same time meets all the stated requirements. Case technologies successfully cope with this task. The cases are in high demand and relevant to use. They perform well in preparing students for exams and Olympiads. It can also be supplemented with out-of-text components: diagrams, graphs, tables, drawings, photographs, etc. At the same time, the case is as informative as possible, includes different points of view, and also examines current problems of biology.</jats:p>
