Design Of Code-block Programming Modeling Learning System Based On Children’s Cognitive Characteristics

With the continuous development of information technology and the improving of the society for talents standard,in order to improve the comprehensive quality of children,and give full play to the comprehensive practice curriculum of primary and secondary schools in the important role of quality education,our country issued the guidelines of comprehensive practice curriculum of primary and secondary schools,and points out that the 3 d design is one of the focal point of information technology.In our country there are many primary and secondary schools to open the 3D design education curriculum,how to meet children’s cognitive development way of 3 d design of the learning process,in the form of rich increase children’s interest,improve children’s learning efficiency,for 3 d design promotion,promoting the comprehensive qualities of children education courses plays an important role.This study aims to design 3D modeling code blocks and modeling cases that conform to the law of children’s cognitive development.Based on the theory of cognitive development,this study reviews the status quo of children’s 3D design education at home and abroad as well as the operation methods of 3D design tools by referring to the preliminary research results such as user interviews and testing experiments.It is found that there are obstacles and limited content of 3D design in children’s use of 3D design tools.Therefore,this study starts with the children’s cognitive development,combined with the research of children’s code block modeling behavior characteristics,with a low threshold while high advanced,guide the auxiliary and free development as the principle,build the child of a code block modeling 3D design cognitive development model,namely the children using a code block for 3D modeling of cognitive development process is divided into four stages: Graphical perception stage,combined modeling stage,imitate the modeling phase,creative design phase,and out of color,graphics,language expression,three-dimensional design content and so on,respectively,for children’s code block code block,which is used to modeling and modeling cases by stages a targeted research,get a different stage of the design goals and principles of design,On this basis,the children 3D modeling code block and modeling case design scheme are obtained.The design scheme is verified by the evaluation experiment,which shows that the model and principles proposed in this study are feasible,and it has guiding significance for the design of code blocks and modeling cases.In order to synchronize with children’s cognitive development process from recognition of geometry to knowledge of natural science to mastery of computer technology,enrich children’s3D design content,consolidate children’s cognition of gravity and materials,and deepen children’s understanding of computer interaction,This study in combination model phase,imitation modeling phase of the block of code to increase "physical" function groups and the "web" functions,strengthen children’s physical and computer technology to nature,etc.The understanding of the knowledge content,make children 3D design content synchronization with the process of cognitive development,realize the physical simulation of three dimensional design and the possibility of human-computer interaction,This method enriches children’s knowledge of 3D design,enhances the interest and self-drive of children’s code block modeling,and thus achieves the purpose of improving children’s creativity and spatial cognition,and promotes the development of information technology education.
