Games are the main element of the unique culture of preschool children, building their spiritual world. Games are an indispensable privilege for preschool children, and deconstructing games is about deconstructing the cultural and spiritual world of preschool children. The play and learning of preschool children are both derived from their inherent needs for survival and development, which reflects the essential identity of the two. However, the current teaching mode of autonomous games for kindergarten children still cannot be effectively carried out, due to safety hazards, insufficient cognitive level of children, and difficulties in integrating knowledge into games in "autonomous game" teaching. Based on this, the author will combine their own teaching experience to discuss the problems and implementation strategies of autonomous learning in children's games.
