Research and Application of Personalized Learning System based on Knowledge Map

At present, there are many online practice and examination platforms, but the design and organization of the questions are relatively simple, and the results of the feedback to the students' practice are relatively simple. In order to enable learners to carry out personalized learning more pertinently and improve the learning efficiency of learners, combining with the research status of personalized learning system of knowledge map at home and abroad, this study proposes to apply knowledge map to the learning system, analyze students' problem-solving situation as a whole, find out students' weak knowledge points and mark it in the original subject knowledge map and push the students' weak knowledge points resource, and a teaching application mode based on knowledge map for personalized learning system is proposed.
