Abstract
This article addresses the challenges and potential of using project-based activities to enhance the cognitive engagement of schoolchildren. The research was conducted to determine the role of project-based activities in supporting cognitive activity and to create recommendations for their continued use in this regard. The primary focus of the study is the introduction of comprehensive forms of project activities into the educational process to increase the cognitive engagement of students. The scientific and practical value of this study lies in the expansion of theoretical knowledge and the development of evidence-based recommendations. The study's findings confirm that the proportion of students with high cognitive engagement in the experimental group (EG) increased compared to the control group (CG); interdisciplinary connections and an integrative approach to learning were developed, enhancing students' overall preparation and readiness for further education; teamwork, responsibility, and self-control skills were strengthened; and opportunities for individualized learning, based on each student's interests and abilities, were provided. Based on the results, recommendations for teachers have been developed, such as incorporating innovative technologies, emphasizing independent work, and fostering student collaboration. These suggestions are designed to improve the effectiveness of the educational process and further enhance the quality of education. In conclusion, the use of various strategies to support the cognitive activity of schoolchildren, along with the introduction of different forms of project-based activities, proved to be effective in stimulating students' cognitive engagement in practice.
