An Analysis Of The Problems And Causes In The Learning Of Three-dimensional Graphics In The Upper Grades Of Elementary Schools

The study of three-dimensional graphics contributes to the development of students' spatial concepts and logical thinking.The primary school stage is the best time to cultivate and develop students' spatial concepts.Therefore,the study of three-dimensional graphics plays an important role in primary mathematics.However,judging from the actual learning situation of students,the upper primary school students are not optimistic about the learning effect of three-dimensional graphics.Based on this,this study uses text analysis and interview survey methods to conduct a comprehensive study on the learning of stereoscopic graphics in upper primary school students.This paper is divided into four parts:The first part gives an overview of the three-dimensional graphics learning in primary schools.Firstly,defined the concept of space and the three-dimensional graphics;Secondly,the content of the course about stereoscopic graphics in the Course Standards was sorted out;Finally,based on the curriculum standard,the learning objectives of the three-dimensional graphics knowledge in the teaching materials are systematically analyzed.The second part is the case presentation of the three-dimensional graphic learning in the upper primary school.Firstly,the author introduced the research object;Secondly,the author conducted an in-depth analysis of the texts of the fifth and sixth grade students in the process of learning the three-dimensional graphics knowledge and the unit test volume.Finally,the problems existing in the students are summarized into three aspects,including the unclear understanding of the basic concepts,the vague concept of space,and the separation of the three-dimensional graphics from the reality of life.The third part is the analysis of the reasons for the problems in the three-dimensional graphics learning in the upper primary school.In response to the problems existing in the students,through in-depth analysis interviews and texts,the reasons are summarized as follows: in the use of teaching materials,teachers' do notunderstand the textbooks well,and the use of exercises is not sufficient;in the aspect of academic analysis,ignoring the characteristics of students and not paying enough attention to students' wrong questions;in terms of the use of teaching methods,the visual demonstration is not in place,the students have less hands-on opportunities,and the guidance of the imaginary method is not clear;in terms of teaching evaluation,teaching evaluation is not targeted,and evaluation of students' learning is not comprehensive;in terms of study habits,the examination questions are not carefully and arbitrarily omitted.The fourth part is the teaching suggestion for the three-dimensional graphics of the upper primary school.Based on the above problems and reasons,the author conducted in-depth thinking and research,and proposed corresponding teaching suggestions,including in-depth study of teaching materials,optimization of teaching content;effective understanding of academic conditions,teaching has a targeted;optimize teaching methods,improve teaching effects;evaluation methods,stimulate students' interest;cultivate students' good thinking quality.
