Design And Implementation Of An Personalized Learning System Based On Knowledge Map

It is one of the trends of the new curriculum reform of our country to promote the comprehensive development of students and promote the individualized development of each student.In curriculum reform,we should emphasize the differences among students' interests,hobbies,needs and abilities.Personalized learning has also become a hot research topic in recent years.In the 60s of last century,the emergence of computer aided instruction laid the foundation for the online teaching of individualized teaching on the computer.In recent years,with the popularity of mobile devices,mobile development technology,and the increasingly mature technology of artificial skills,mobile learning has achieved good results in real life.The characteristics of mobile learning itself,such as short time,micro content,convenient learning,and anytime,anywhere,can also play a great role in promoting the personalized learning of students.The relevant literature at home and abroad is consulted,most of the scholars in this field ar'e to build a user model,so that the system can better adapt to the learners.The author thinks that personalized learning system is not only expressed in the system can adapt to learners well,and learners should also adapt well to the system,but the current research on this aspect is less.This papersummarizes the shortcomings of the past personalized learning system.Combined with the visualization advantage of knowledge map,we take the knoxwledge point of C programming course as learning content to achieve an online personalized learning platform.On the theoretical level,this paper focuses on the research status of personalized learning system,and also analyzes the application of knowledge map in this kind of system.Under the guidance of constructivism,biologic rhythm theory and emotion cognition theory,a system model based on knowledge map is constructed,which lays a good foundation for the design and development of the system.At the practical level,through user needs analysis,system function analysis and knowledge analysis of C progranming,a series of analysis is done.The function of the system is determined and the interface diagram is drawn.Finally,the related technology is applied to develop the system.This system is divided into two modules:the backstage management system and the client system.The background is divided into four functions:the user management,the knowledge point management,the knowledge map management and the discussion and communication management.The client according to the different user identity(teacher user or student user)set different function modules,the core function of students is:students end user learning style prediction,personalized learning content push,learning emotion acquisition,learning outcomes assessment,personalized data display.The core function of the teacher's realization is to learn the visual display of the results of the learning of the user group.
