Graphical programming modeling optimization design based on cognitive development theory

This article aims to design a suitable graphical programming modeling learning platform and teaching mode for primary school children to help them break the barriers of 3D design and freely express their creativity. The article based on cognitive development theory, select users to conduct research interviews, observe the process of users operating children’s programming tools and 3D modeling tools, understand their mastery and operating experience, and obtain optimized design directions and functional requirements. The result comes that children’s receptive ability and focus of needs vary according to the specific stage. On the basis of enhancing interest and ease of operation, how to break through traditional modeling methods is the key point. Based on the theory of cognitive development, the needs of children are explored through user interviews and behavior observations, and a graphical programming modeling platform and teaching cases that are more acceptable to children are designed from the perspective of children’s cognitive development.
