The Research And Application Of Question Organization And Personalized Exercise Evaluation Based On Knowledge Map

The use of the computer network has been an important part of modern teaching.It’s an effective way for students to learn and consolidate knowledge by doingnetwork-based online exercises and tests. At present, the organization and managementof some of the online training systems are too simple as well as the feedback fromstudents, which results in students’ failing to know its own learning situation in anintuitive and comprehensive way. Therefore, how to organize and manage orderly anddirectly reflect the questions of students is an important issue to be solved.In this paper, the application of the knowledge map and knowledge map inknowledge management has been studied and the characteristics of knowledge points inmiddle school have been investigated so that the knowledge map is applied to testlibrary management and the organizational test model is proposed which is based on theknowledge map, and the personal knowledge map that can help with students personallearning feedback is generated in accordance to students knowledge learning level. First,the personalized organizational practice model based on a knowledge map is built whichalso has built a relationship between knowledge points and the test questions and theknowledge points can be managed in the form of the knowledge map, so as to organizethe test questions in an orderly way with the help of the knowledge map. Then, how thestudents master the knowledge points involved in the exercises can be determined byanalyzing the results, so that the personal knowledge map consistent with personalknowledge can be generated which can give the students feedback in a visual direct way.Finally, taking middle school physics courses for an example; we have designed andimplemented the individual practice system based on knowledge map. The system uses knowledge map to manage the test bank, the individual practice knowledge map to getfeedback and at last we have verified the organizational model based on the knowledgemap can be applied in the personalized secondary school training system.The personalized test practice system based on knowledge map is a new itemmanagement model that can reflect changes in the links between questions, and thisevaluation based on knowledge map can help the students to form a global view ofknowledge, improve learning efficiency, and increase the ways to understand studentsfor teachers.
