Research On The Construction Of Knowledge Map Of Robot Education In Primary And Secondary Schools

With the development of artificial intelligence and intelligent manufacturing,robot education has gradually entered primary and secondary schools to cultivate talents,and has attracted attention from society.Robot education integrates multi-disciplinary knowledge,and emphasizes close integration of theory and practice.It is of great significance for improving the education system and cultivating future-oriented and modern-oriented comprehensive talents.So it is important to promote the development of robot education.However,there are some problems in the development of robot education.Firstly,the popularity of robot education is not enough due to imbalanced education resources in different regions and schools.Secondly,the development of school-based curriculum is difficult,because robot education is not an independent discipline,and because of the lack of a unified and standardized outline and teaching materials.Finally,most of the robot lessons are organized by associations or interest classes in school,and are oriented by robot competitions,which leads to that students are limited and their learning is not continuous.The research target of this paper is to construct robot education knowledge map.On the basis of analyzing characteristics of robot education and influencing factors of robot education knowledge map construction,the schema layer and data layer of robot education knowledge map are respectively designed,and the method and the goal of constructing knowledge map of robot education is determined.In addition,the construction of the knowledge map was carried out,including crawling book information in Jingdong by Scrapy,doing word segmentation based on Jieba and extracting keywords,constructing the ontology in Protege based on analyzing the processed data,using BeautifulSoup to crawl information on Baidu Encyclopedia,as well as carrying on the information extraction work.Then,data storage and visual display was finished in Neo4j.After the construction of the robot education knowledge map for primary and secondary schools,its application in education and teaching was discussed,and the robot education teaching model based on knowledge map in junior high school is proposed.Finally,the teaching analysis and design was carried out with the lesson of "Getting to Know About Robot" as a case.The results show that applying the knowledge map to the field of education and constructing the knowledge map of robot education in primary and secondary schools can clearly show the complete discipline structure and the relationship between knowledge points of robot education in primary and secondary schools.This can help students to build a basic cognition of the subject structure,integrate fragmented knowledge,improve their own knowledge system,and promote the positive transfer of learning.Moreover,it can provide teachers with reference and improve their efficiency of lesson preparation and teaching effect.In addition,knowledge mapping can also be improved in teaching practice.All in all,the construction of knowledge map of robot education in primary and secondary schools can solve the problems existing in the teaching practice of robot education to some extent and promote the in-depth development of robot education.
