In the modern world of technology and information, the ability to use a computer and its software has become an essential component of an educated individual. Computer modeling, as one of the branches of informatics, holds a special place in the educational process because it allows not only the theoretical assimilation of material but also the practical application of knowledge to solve real-world problems. Consequently, the teaching of computer modeling is gaining increasing popularity and requires a specific approach to the organization and conduct of informatics lessons. The purpose of this monograph is to study the features and effective methods of teaching computer modeling in informatics lessons. Thus, this monograph aims to deepen knowledge in the field of teaching computer modeling and to provide practical recommendations for improving the quality of informatics teaching in schools. The implementation of the proposed methods will prepare students for the modern challenges of the information society and contribute to the development of their professional competencies in the field of IT.
