Comparing Human-Designed and AI-Enhanced Science Lessons: A Pilot Study in K-5 Education

Artificial Intelligence in Education (AIEd) is a rapidly growing field, yet concrete applications in early Science Education remain limited. This pilot study investigates the impact and perception of generative AI tools in designing and delivering science lessons in K-5 classrooms, compared to traditional human-designed instruction. The research was conducted in two phases: i) a preliminary survey involving Italian nursery and primary school teachers to assess familiarity and expectations toward educational technologies, and ii) a field intervention comparing six traditional and six AI-assisted science lessons, followed by a second structured questionnaire completed by seven teachers. Results reveal that while traditional teaching remains essential for fostering foundational skills, empathy, and real-world connections, AI/GAI tools can enhance engagement through immersive and adaptive experiences. However, effective integration requires targeted teacher training and mindful implementation. This study highlights the complementary strengths of human and AI-led instruction, advocating for balanced, inclusive, and pedagogically grounded innovation in early STEM education. However, further research is needed to evaluate long-term educational impact and scalability.
