The Construction And Application Research Of Knowledge Graph Of Middle School Python Course

With the growth of grades,the content of the curriculum of middle school students has gradually deepened,and their subject knowledge has gradually been systematic.After entering middle school,students gradually strengthen their independence of learning;In modern classroom teaching,teachers usually use narrative method and heuristic method to teach.In addition to classroom teaching,students'independence has been strengthened and their learning activities have become more diversified.In family education,due to the increasing difficulty of students'learning materials,the direct help given by their parents will be greatly reduced.The above situation,together with the innate individual differences of students,leads to the phenomenon that different students deviate from their learning goals when they study the same course.And students often can not grasp the relationship between the various learning knowledge points,but simply remember scattered knowledge points.This is unfavorable for students to build knowledge and enhance their abilities in depth.Knowledge graph is a technology that focuses on the various semantic relationships between knowledge and knowledge,and stores,displays and mines their relationship with visual technology.Knowledge graph can effectively display the relationship between the whole course knowledge,help students organize knowledge and improve learning efficiency.With the rapid development of artificial intelligence technology,the basic course of artificial intelligence technology of Python has gradually moved to middle school.This paper will focus on the middle school Python curriculum,combined with the construction technology of knowledge graph,and take the construction and application of knowledge atlas of middle school curriculum as the main research content of this paper.The main research process is as follows.:Firstly,the research background of this paper is expounded,and the research content of this paper is put forward through the analysis of domestic and foreign knowledge graph and related research literatures of adaptive learning systems.Secondly,it introduces the related concepts of ontology and ontology construction tools,as well as the relevant theoretical knowledge of knowledge graph.Finally,it summarizes the related technologies involved in knowledge processing.Third,through the study of the general construction process of the knowledge graph,combined with the characteristics of the middle school curriculum.The pattern layer and data layer of the curriculum knowledge graph are designed.The fourth chapter,for the design of the previous chapter,first constructs the four steps of semi-automatic construction of the curriculum knowledge map,ontology modeling,data mining,knowledge extraction,knowledge storage;then combined with the knowledge characteristics analysis of middle school python course,constructed middle school python The curriculum knowledge map,and the technology involved in the construction process is introduced in detail.Fifthly,based on the knowledge graph of Python course,the python adaptive learning system model is designed,and the recommendation and retrieval based on knowledge graph are expounded.Finally,summarize the research work and the indications and prospects of the deficiencies.
