Design And Implementation Of Children's Situation Cognition System Based On Ios

The learning and development of children,especially young children,has always been the focus of attention.With the adjustment of national population policy,the number of newborns increased,the number of newly built kindergartens and children in kindergarten increased significantly,and the whole scale of preschool education industry grew rapidly.The development of regional teachers is unbalanced,the teaching form is single,the primary school of preschool education is becoming more and more serious,and high-quality kindergartens and excellent preschool teachers have become scarce resources.But preschool stage is precisely the rapid development of children's brain,nervous system and other physical functions.The critical period of listening,speaking,reading and writing is developing in an all-round way,and the gradual formation of thinking and character is the starting point for children's life.Knowledge is the gymnastics of brain development,which helps children,especially preschool children,to acquire knowledge and further promote their thinking development and personality development,which has very important practical significance.With the rapid development of modern science,the progress of the Internet of things and related intelligent technology has been paid more and more attention.How to use scientific and technological means to help children develop high-quality and efficient cognitive learning has become an urgent task to be solved.Therefore,this thesis puts forward the viewpoint of children's situational cognition based on situational cognitive theory,cognitive psychology and children's cognitive development stage theory.On this basis,by using the relevant technical means such as Internet of things,sensor and Web platform,and drawing lessons from STEM education concept,the children's situational cognition system based on the Internet of things technology is studied and implemented.The main goal of the system is to help children under the age of six to realize cognition in the context task of the Internet of things perceptual interaction,and to master knowledge and thinking ability better.Therefore,this system abstracts the characteristics of children's situational cognition into two models: perceptual-motion model and form-operation model,and designs sensor building blocks,sound and display interactive components by refining children's basic interactive behavior.The situational task form is realized.Situational cognitive system mainly includes five parts: content management,situational construction,situational execution,evaluation and analysis,and system management.It is divided into three layers: perceptual interactive device,Internet of things gateway and system platform.The situational cognition system platform mainly relies on the Django open source Web framework which is written by Python language.The sensor building blocks and sound interactive components communicate with the Internet of things gateway through ZigBee and Bluetooth respectively.The Internet of things gateway is composed of Flask micro framework.Display interactive components and Internet of things gateway via Wi-Fi access system platform,the application is implemented by Bootstrap front-end framework written in JavaScript language.Through the design and implementation of the children's situational cognition system based on the Internet of things technology,it can effectively improve the learning cognitive experience of the preschool education clients.It provides ideas and references for the further development of the future education combined with science and technology intelligence.
