| Information technology has not only changed our life,but also changed our learning environment and way.In 2022,the new version of the curriculum standard of mathematics in compulsory education stage was released,in which a module of comprehensive practice was added,aiming at enhancing students’application of mathematics by means of educational informatization.Introducing information technology into teaching can effectively change students’ learning style and inject new vitality into the classroom.This paper builds an online learning platform with the help of the Internet,aiming at applying information technology to change the teaching problems of graphics and geometry in primary school mathematics teaching.In the first-line teaching process,there is a lack of the display of geometric models and the connection between old and new knowledge,and students often have problems such as vague spatial concepts when learning graphics and geometric content.In this paper,with the help of online learning platform,geometric model and mind map are added to the design of the platform,and at the same time,pictures,texts,videos and other related contents are added to the online learning platform as extended materials to assist students in learning.In this paper,the elementary school mathematics "the surface area of a cylinder" is taken as an example,and the application of teaching technology is of great practical significance for the improvement of front-line teaching.This study is mainly divided into the following parts.Firstly,this study uses the method of literature analysis to search for keywords,find relevant literature and sort it out.By analyzing the literature,it gets the current online learning platform and the teaching status of graphics and geometry at home and abroad.Starting from the current situation,it analyzes the current predicament of graphics and geometry teaching,finds the research theme of this paper,and further selects appropriate research methods according to the research theme.Secondly,by combining specific teaching theories-children’s cognitive development theory,constructivist learning theory,geometry teaching stage theory and h5,Vue,PHP and other related technologies,the design and development of primary school mathematics network learning platform are carried out on the basis of analyzing the feasibility;Thirdly,based on relevant theories and technologies,the teaching process is designed,and experimental research is carried out by means of questionnaire to investigate and test students’ use of the online learning platform,which is used to verify the use effect of the online learning platform for primary school mathematics on the teaching of graphics and geometry.The research results show that the research enriches the relevant theoretical and practical research results of the online learning platform,which provides reference for further perfecting and improving the theoretical and practical research of the course of "Graphics and Geometry" in primary school mathematics,and also has certain reference for the construction of learning platforms for other disciplines.Finally,this paper makes a summary and prospect.On the one hand,it expects to get feedback from teaching and provide more opinions and suggestions for platform construction.On the other hand,in order to better assist teachers and students in the teaching process,this paper looks forward to further developing teaching platforms to better assist teaching and learning. |
