This chapter examines the importance of integrating artificial intelligence (AI) and STEM (Science, Technology, Engineering, and Mathematics) in early childhood education, highlighting how this integration contributes to foundational skill development in young children. AI's role in education is emphasized through its ability to provide interactive and personalized learning experiences, thereby fostering independent learning processes among students. Integrating AI tools in early learning increases children's interest in STEM subjects and supports teachers in various instructional tasks. The chapter presents three main paradigms of AI-based STEM education: AI-directed, AI-supported, and AI-empowered STEM education. These models serve distinct functions in the learning process, such as as automating access to information, providing real-time feedback, and creating student-centered learning environments. Specifically, natural language processing tools like ChatGPT support students' individualized learning paths by offering instant information on STEM topics and assisting teachers in preparing educational materials. A practical example, "Plant Exploration with a Smart Assistant," demonstrates a model for enhancing children's scientific observation skills and environmental awareness through AI. This activity enables young learners to explore nature with the support of AI, illustrating the potential of educational technologies in early childhood education. Finally, the chapter underscores AI's contribution to the development of critical thinking and creativity skills. AI's capabilities in providing instant feedback and accessible information encourage in-depth learning experiences in STEM education, equipping students with a more informed approach to data analysis and knowledge evaluation.
