Development And Application Of Primary School Mathematics Auxiliary Teaching Tools Based On Knowledge Grap

The teaching of primary school mathematics plays an important role in basic education in China,and the teaching of mathematics has always been a strong discipline in primary and secondary education in our country.This article applies the information technology of knowledge graph to efficiently organize classroom teaching,combined with the needs of current era development,to cultivate students’ core mathematical literacy.Utilize knowledge graph technology to integrate mathematical subject knowledge,develop auxiliary teaching tools,and assist frontline mathematical subject teaching.This article mainly includes the following four aspects of content:(1)Using China National Knowledge Infrastructure(CNKI)to search for relevant literature on primary school mathematics teaching,using CiteSpace to analyze the current focus of primary school mathematics teaching research.Through knowledge graph and keyword highlighting analysis of the literature,the author found that the current focus of primary school mathematics teaching research is on the cultivation of mathematical core literacy;(2)Analyze the knowledge points and logical structure of primary school mathematics textbooks,and apply Protege to construct a knowledge graph of primary school mathematics.The entire process of constructing a graph of elementary school mathematics knowledge includes the collection and analysis of data sources,using concept extraction and rule matching based relationship extraction.Integrate online teaching resources in the process of constructing a knowledge graph to provide data for the development of teaching aids;(3)Save the constructed knowledge graph to the graph database neo4j and connect it to the neo4j graph database using Python.And through front-end visualization technology,the graphical database is presented in a browser,and an auxiliary teaching tool is developed using Python’s Flask framework.The auxiliary teaching tool can query elementary school mathematics knowledge points and related teaching resources;(4)Apply auxiliary teaching tools to design teaching cases to cultivate students’ core mathematical literacy.Adopting a flipped classroom teaching mode,students apply teaching aids to preview in advance,aiming to guide students to think independently.In the teaching process,firstly,by combining pictures and figures,students can understand mathematical concepts;Secondly,encourage students to actively practice and apply logical thinking to draw mathematical conclusions through steps such as guessing,operation,and verification;Finally,students independently summarize and draw a mind map for this lesson,reflecting on the connection between their thinking and the knowledge they have learned.
