目的 基于知识划分理论和查特曼叙事分析框架，探索儿童科普游戏的叙事设计框架。方法 梳理了现有设计问题及成因，分析、构建设计理论框架SPGD;基于该框架自主研发一款以“抗生素耐药性”为主题的RPG科普游戏，将其作为科普学习材料进行干预实验，以确保实验数据能够准确反映理论框架的有效性。结果 实验数据显示，游戏实例能够有效指导儿童科普游戏叙事设计实践，并保证儿童科普学习的主观体验和客观效果。结论 基于SPGD框架开发的科普游戏可以有效提升儿童对特定科普知识的认知效果和科普学习体验。

The work aims to explore the narrative design frame of popular science games for children based on the knowledge division theory and Chatman narrative analysis frame. The existing design problems and causes were analyzed. A design theoretical framework SPGD was constructed; Based on this framework, an RPG popular science game with the theme of "antibiotic resistance" was independently developed and used as a popular science learning material for intervention experiments to ensure that the experimental data could accurately reflected the validity of the theoretical framework. The experimental data showed that the game examples could effectively guide the narrative design practice of popular science games for children and ensure the subjective experience and objective effect of children's popular science learning. The popular science games developed based on the SPGD framework can effectively enhance children's cognitive effect and learning experience of specific popular science knowledge.
