The Research Of Student Model In Adaptive Education Hypermedia System

In adaptive education hypermedia system,in accordance with each student's learning goals,preferences,knowledge,student build basic model,the interactive of system and student build at the student model based on the needs of student can make the appropriate adjustments.The better student model can make the system structure clearer,easy to maintain and the more importantly,the system model parameters in accordance with students to provide services to meet the requirements of adaptive,student improve learning efficiency through adaptive hypermedia system,which should depend on the student model.Because of the restrictions of theoretical basis,students model problem has never been a very good solution. Student model in adaptive education hypermedia system not only records student's domain knowledge,in order to highlight the self-adaptive,student model must also include student's personality characteristics,such as interests,preferences,background knowledge,etc.And the majority of existing models are static,and once the student model determine system operation during the additions and deletions can not change their property to carry out the operation,which is restrict the system's adaptability。Therefore,the build of the student model become a focus and hot spots in adaptive education hypermedia system research.The purpose of the research of student model in adaptive education hypermedia system is to be a way to build student model.Case analysis method,document analysis method,system scientific method,instructional design method and object-oriented software design method are used in the research.The mainly work of the study are as follows.(1)The research of theoretical of adaptive education hypermedia systems and student model.Analysis of domestic and international status in this areaon the basis of comparative study,and explores the principles of modeling and plans student model.(2)The build of student model.In accordance with the basic framework of student modeling methods analysis the student model implementation of the personality characteristics of students digging and students measure the degree of knowledge. (3)The implementation and updating of Student model.The discussion of student model implementation methods and update rules.(4)The development of application.Thesis design and develop an adaptive education hypermedia system to verify the availability of student model.After a series of research work,research get the thesis research results.(1)Adaptive education hypermedia system and the theoretical model of students study at home and abroad of the status quo in this area,dynamic comparative study.Summed up the students build a model of the theoretical basis and analysis of case-related system.On this basis,the students explore the principles of modeling and plan students model.(2)The build of student model.Under the guidance of ideology and design principles about student model,which analyze the expansion of content and student's the personality characteristics of individual students model the characteristics of middle school students for in-depth information mining,using Bayesian network methods on students model secondary school level of knowledge,knowledge of the degree of uncertainty for reasoning,thus allowing students to study the process of studying the adaptive navigation and adaptive content to display.Further summing up a set up methods of building student model,which provide an important basis for the implementation and updating of student model.(3)The implementation and updating of student model.At the basic of building student model thesis discusses the content of the student model,learning content as well as student's emotional changes and implementation of students preferred and student model's initialization.Student model of update rules to update the concept,content and subject of study update,students acquire knowledge value update, the update preference students discussed in detail.Summed up the methods of implementation and updating of student model,which provides a theoretical foundation about the application of system.(4)The development of application.Thesis design and develop an adaptive education hypermedia system to verify the availability of student model.Innovations in the thesis are as follows:(1)Developed a more effective way to build student model,and this theses provides a method of reference for the research of student model in other educational systems.(2)The method of implementation and update of student model in this thesis inproved the drawbacks of not promptly update at a certain extent in the original student model in adaptive education hypermedia system.Further research work is to study the structure of student model.
