Design And Implementation Of An ABA Learning WeChat Tool For Autistic Children

Autism is a representative disease of neurodevelopmental disorders.The number of people,especially children,with autism has been on the rise in recent years.Autistic children face different difficulties,such as learning,communication,and behavioral skills.In order to increase people’s awareness and attention to autism,the United Nations designate April 2each year as World Autism Day.There is evidence that the autism cannot be cured,and the intervention method is an important factor affecting the rehabilitation effect of autism.Applied Behavior Analysis is one of the most effective intervention methods for autism,which is adopted by autistic institutions.This thesis investigates mobile applications in the field of autism,explores the teaching class model of autism institutions,designs and implements a teaching aid for autistic children’s applied behavior analysis teaching.By investigating the teaching class scenes of autistic children,problems that paper records are not easy to keep,teaching records are uneven,data analysis is not timely,and a lot of manpower is consumed are found,the thesis designs the system process and architecture specifically,and divides the service into four modules: user management,classroom management,application behavior analysis records,and data analysis.The system implements the informatization of the autism class,designs the class teaching record template with the core of applied behavior analysis,systematizes the teaching data analysis process by making full use of the advantages of the ABA teaching method,and uses visual charts to show the teaching progress and effects to teachers and parents intuitively,thereby adjusting the teaching plan and improving the quality of classroom teaching.Meanwhile,combined with the teaching class of autism institutions,the technical selection of the system is determined.Taking the mature application of wechat public account as the entrance,the front-end and back-end separation development modes are selected,of which Vue and Spring Boot are chosen as front-end and back-end frameworks,the My SQL database and Hibernate frame are used for data management,which has strong scalability and easy maintenance.After completing the system implementation,a complete functional test is conducted using test cases,the system performance tests are carried out in both aspects of the average response time and resource utilization,which achieve the expected goal of system development.Meanwhile,in the expert scoring of the application behavior analysis records module,the feasibility of the random forest algorithm in the autism classroom is proved by simulating class teaching data.The accuracy rate of prediction in the data set reaches 93%.The main significance of this thesis is that it uses information technology to assist autism class teaching,solves the problems in the existing class of autism institutions,uses the system to effectively collect classroom teaching records,and improves the quality of class teaching by analyzing teaching data.Based on the work of this thesis,in the future,multi-modal data collected by intelligent terminals can be integrated into the system to build a comprehensive information-based autism classroom.
