THE FEATURES OF THE APPLICATION OF THE CASE STUDY METHOD IN CHEMISTRY AND BIOLOGY LESSONS

The case study is a contextual learning method that uses real-life examples to actively engage learners in the learning process. It not only encourages them to discover suitable solutions to practical scenarios but also fosters their active participation through collaborative discussions and debates. The method involves a case that explains a specific practical scenario, a problem statement, references and extra information (audio, video, and other resources. The purpose of this study is to investigate the effectiveness of the case study method in the teaching of biology and chemistry in secondary schools. The experiment was conducted based on a specialised boarding school “Information Technologies” from January to April 2024. Students of the 9th grade took part in the approbation of the developed case-study chemistry and bilogy tasks. The topics included in the experiment: “Halogens”, “Group 16 (A) elements”, “Group 15 (A) elements”, “Group 14 (A) elements”. Cell cycle”, “Patterns of heredity and variability”, “Microbiology, and biotechnology”. The significant improvements in the increase in the quality of knowledge of the experimental group in chemistry and biology highlight the effectiveness of the case study method. Furthermore, the analysis of the results of the survey to determine the level of motivation before and after the experiment showed that most of the students in the experimental classes increased their level of motivation, which improved their perception and attitude towards learning chemistry and biology.
