Child’s active learning during project activities is a complex process considering contemporary educational science. This method of learning fosters motivation for learning and helps children recognize the importance of acquired skills and knowledge as well as their application in everyday life. In this process, each child takes individual responsibility for their own learning, thereby developing a sense of competence. Projects that are held in educational institutions represent a framework of activities in which children explore a certain topic related to their interests. It is of great importance to respect the elements that influence the projects: positive atmosphere, provision of materials, a broad spectrum of activities and the role of the environment. The constructivist theory of learning, which is the basis of active learning, provides guidelines for support and directs this type of learning. This pedagogical approach aims to encourage independent thinking, research and problem- solving, which leads to deeper understanding of the learning content. During project activities, children are actively involved in the learning process, they collaborate with their peers, and apply acquired knowledge in real-life situations. Educators who support active learning during project activities encourage dialogue, ask questions, and provide support rather than just transmitting Information.
