AR-technologies can be widely used in the educational process using ICT. Especially valuable is the use of AR-based applications for the visualization of illustrations of models of objects and processes in school books. The use of electronic educational resources using AR-technologies can improve the quality of students' knowledge, as well as provide teachers with a wide range of new opportunities.Using AR technology allows you to design and create effective learning resources. This develops students' creative thinking and increases their motivation to learn.In this paper, we consider a model of a learning system using augmented reality technologies for visualizing illustrations in school textbooks.A survey of secondary school teachers showed the possibility, interest and effectiveness of using e-learning tools based on AR technology. Pupils can use this electronic resource both in class at school and at home during independent study.Students of Kherson State University, interviewed in the STEM education system, showed a willingness to work with augmented reality technologies.To assess the prospects of using AR-based applications in the educational process, an expert method was used. Experts evaluated the prospects of using AR technology to visualize 2D and 3D models of educational objects. For evaluation, a five-point Likert system was chosen.The developed model can be used as a means to create the basis for future research, development and dissemination in the system of educational institutions. The proposed model of the learning system was tested in the classrooms of students in the learning process at STEM.
