Touch-based learning technologies in early STEM education affect young children's learning and engagement, as this chapter shows. Five-year-olds planned, programmed, and implemented four touch-based instructional activities during a summer camp in a qualitative study. Key findings show that touch-based gadgets encourage active involvement, multimodal learning, and STEM comprehension. The chapter emphasizes the benefits of touch-based learning in early childhood using HCI and educational psychology theories. It also emphasizes how these tools can assist varied educational contexts and intuitive and exploratory learning. The results imply that touch-based tools can improve STEM learning outcomes, allowing educators and policymakers to improve early education. This research helps harness technology for effective and interesting STEM education for kids.
