Research On The Design Of Children’s Graphical Programming APP Based On Scratch

With the development of artificial intelligence,the future world will be computerized,programmed and informationized.Children’s programming has become an irreversible development trend.Preschool children are a special group of children.Aiming at the shortcomings of the existing children’s programming app for preschool children,such as the graphical representation is not intuitive,the module layout is unreasonable,and the interaction design is too complex,this study takes mobile application as the carrier,takes preschool children aged 3-6 as the research object,from the perspective of art,combined with computer science,computer science,computer science,computer science and so on In the field of psychology and other disciplines,using interdisciplinary research methods,this paper makes an in-depth study on the interactive design of graphical programming app for preschool children.Academic research part: firstly,in the aspect of children’s graphical programming software,this paper analyzes scratch and domestic mainstream children’s graphical programming software,and summarizes the five characteristics of children’s graphical programming software: coordinate system,object / role,message and message transmission,event processing,modularization / code reuse,and continues to follow in the subsequent design practice.Secondly,in terms of preschool children’s app,it analyzes the physical function,sensory system and psychological characteristics of preschool children,including audio-visual characteristics,tactile and physical characteristics,spatial cognitive characteristics and psychological cognitive characteristics.According to these characteristics,it summarizes the general principles of interaction design of preschool children’s app,It provides a basic theoretical basis and reference for the interactive design of preschool children’s graphical programming app.Finally,in terms of preschool children’s graphical programming app,according to the previous research and summary,combined with the research category of graphical programming,the interactive design principles of graphical programming app are further summarized as the guiding principles of graduation design works.Practice design part: guided by the interactive design principles of children’s graphical programming app,according to children’s playful nature,using the teaching concept of "teaching in fun",we designed and produced a graphical programming game app specially designed for 3-6-year-old preschool children,elaborately polished the building block programming interface and interactive experience,Let children fully experience the fun of playing in the game,while receiving logical thinking training,fully mobilize children’s interest in programming.At the same time,the proposed principles are applied in the design of specific game cases.I hope this study can provide some valuable reference for the improvement of interaction design of preschool children’s graphical programming app in the future.
