Design And Implementation Of The Intelligent Infant Evaluation System Based On IRT

With the rapid development of information technology,the traditional mode of preschool education has been unable to meet the needs of modern social education.In order to facilitate the management and enrich teaching contents,most domestic preschool educational institutions have fully implemented information management.As an important reference and promotion target for preschool education,the assessment of children's ability level is paid much attention by the parents and educators.In order to rationally plan children's learning goals and development direction,it is urgent for modern parents,educators and children to understand children's ability level.But at present,the evaluation system for children in the market is not good enough,which lacks theoretical basis,and cannot be combined with kindergarten education to provide guidance for parents and teachers.This article relies on the actual project of Intelligent infant evaluation system.Combining with the present situation of infant evaluation system and the actual demand of kindergarten,using SSM frame,SQL server and item response theory,we design and implement this system using java programing language.The system contains Assessment of children's ability,Child growth report,Historical data management,Evaluation system maintenance,Basic information maintenance,and Authority and system management.We use mathematical model of IRT and EAP to compute children's ability value,and to get Child growth report,and taking this as the core to develop all kinds of peripheral functions.This paper firstly discusses the present situation of evaluation system for children at home and abroad,then put forward the goal to achieve,and then analyses the system requirements in detail,and expounded the system design combined with the technical theory.Finally,we display the system through the system implementation screenshot,and test the system carefully.At present,we gave the system a tryout in the kindergarten under the company and got a good feedback.The system is operating normally now,and it improved the professional behaviors of teachers,which provide teachers and parents a platform to communicate.The system improved the overall efficiency of the kindergarten greatly.
