ABSTRACT: With the deep advancement of educational digitalization, online education has become a significant learning modality for children aged 3 - 12. However, in practice, online education for this age group faces prominent challenges such as difficulty sustaining attention, insufficient interactivity, and lack of personalization. Based on Piaget’s theory of cognitive development, this study systematically analyzes the developmental characteristics of children aged 3 - 12 in terms of perception, attention, memory, and thinking, and their implications for online education. The study proposes that effective online education for children should follow design principles such as “short duration with high frequency, gamification-driven learning, multi-sensory participation, and embedding social interaction”. It further constructs a four-dimensional optimization framework covering curriculum design, teaching strategies, technological adaptation, and home-school collaboration. The study argues that only by taking the laws of children’s cognitive development as the logical starting point for online education can a paradigm shift be achieved from technology-driven educational migration to development-oriented educational innovation.
