Research on Knowledge Retrieval of Junior Middle School Mathematics Micro-course Based on Knowledge Map

摘要

With the arrival of fragmentation era, people's learning methods have changed greatly. Micro-courses have become a very popular learning method for learners, but micro-course are fragmented, which makes it difficult for learners to retrieve the knowledge they need from a large number of learning resources, and the knowledge they learn is scattered and lacking. Without effective organization, it is difficult for learners to learn systematically. As a tool of knowledge management, knowledge map can visually show the location of knowledge points and the relationship between knowledge points. Therefore, this paper puts forward the idea of introducing knowledge map into the junior high school mathematics micro-course resources, constructing the micro-course knowledge retrieval model, it is convenient for learners to find the required knowledge,promoting learners' learning.
