Analysis And Design Of Auxiliary Examination System Based On Knowledge Tree

On the academic research,the subject knowledge capacity test and evaluation to the personalized teaching have been confirmed to be quite effective,but in the practical teaching,the teacher must analyze and manage the examination results for each student,which goes beyond personal ability.Therefore,on-line examination and learning system is becoming the effective means of personalized teaching information.By studying the status at home and abroad,we found that the online test and study system is not very smart,can't test or evaluate students' ability effectively,and the application in the practical teaching effect remains to be improved.According to the above problems,this paper studies the design and implementation of online examination and learning system which based on the tree of knowledge,hoping to explore the subject knowledge ability effective methods of on-line examination and evaluation analysis.First of all,this paper has carried on the research for present situation of the online test and study system home and abroad,expounds the necessity and the importance of learning system and build online tests respectively from two aspects between the research background and research significance.And then according to the research and development status of related fields at home and abroad put forward the current problems in this field of research,and leads further to the research objectives and research tasks of this paper.Secondly,aiming at the problems existing in the system research of the online test and study,this paper studied the navigation and visualization method based on knowledge tree,the systems' framework of the on-line examination and learning system based on knowledge tree,a nalyzed the principle of digital resources based on the knowledge tree navigation and visualization technology.Thirdly,according to the standardization process of software engineering,the paper completed the design of the on-line examination and learning system based on knowledge tree design.Around,on the basis of system requirements,this paper analyzed the overall business process and different business process around roles according to the demand analysis in detail;Then the paper completed the general structure of the system design and system function module design,including the role of the function of each function module design and design;then designed the system interface according to demand;Finally,there carried on the database design,including concept design,logical design and physical design.Finally,the thesis completed the development and implementation of the system.Then it discussed respectively the realization of the function in two accepts: the business function module and background management module,which including several child modules,such as knowledge management module,resource module,user management module,test module,evaluation analysis module and so on.At the same time,we have also made a system soft test according to the system test cases from various aspects,and have given a test result of the system.Test results show that the function basically reached the expected results,but of course,there also need further in-depth study on the system performance,security,scalability,etc.
