Reason Analysis And Countermeasure Research On The Difficulty Of Three-view Reduction Geometry In Upper Primary School Students

The three views are the essential content of the senior high school mathematics,but also the basis of geometric teaching,is to cultivate the primary content of the primary school students' spatial concept,among which the difficulty of the three view is to restore the stereoscopic geometric view from the three view.In the current mathematics teaching,for the graphic teaching,teachers generally use the method is to ask students to imagine,which students logical thinking ability and spatial imagination ability to put forward higher requirements,so that part of the three-dimensional geometry is more difficult to learn,Is not easy to understand,making the students learn less effective.Therefore,it should be investigated to study the current causes of primary school students to view the three reasons to restore the geometry of the more difficult reasons,and one by one analysis,and then find out the corresponding countermeasures for the occurrence of the problem of the right medicine,given to determine the effective solution to the three-view reduction geometry So that students can trace,so that even if the space imagination is not so good primary school students can also accurately answer the three views to restore the geometric problem,so as to cultivate the primary school students to lay a good foundation for the concept of space,And then cultivate students' logical thinking ability and spatial imagination ability.In this paper,through the questionnaire survey and interview method and other research methods primary school of 48 students in Zoucheng to conduct research,analysis of the results obtained in primary school students in the three-view reduction of geometric process A few questions: most of the primary school students to geometric graphics recognition is not careful enough,cognitive is not clear,the problem is not comprehensive consideration,resulting in the restoration of geometric errors;consider not comprehensive,do not carefully do not standard,The actual length of the solid line and the geometry is adjusted proportionally.According to the interview and the analysis of the results of the interview,the author concludes that the three reasons for the reduction of the geometric difficulty of the students are as follows: the basic knowledge of mathematics is not strong,not comprehensive,can notform knowledge network in the mind and can not be learned and used,Do not know how to learn,do not develop a good learning habits,too impetuous,too lazy,to do the results of the existence of luck,not test;space to imagine Ability and logical thinking ability is poor,hands-on ability is poor.According to the survey results,the following teaching strategies are put forward:teachers must pay attention to the knowledge before and after the response,to help students to play the basic knowledge to help in the mind to form a knowledge network and flexible use;So teachers should make the senior students grade the attitude of the discipline of this discipline,to develop their good study habits,urging them to be diligent and diligent,careful examination;teachers should pay attention to the students to do three views to restore the geometry of the Practice should be more students to different types of questions,all-round practice;teachers should pay attention to cultivate students' space imagination and hands-on ability,in daily life and learning to give them some three-dimensional graphics to let them see,Think,painting;for the three-dimensional geometry of the teaching,conditional use of multimedia to show its dynamic process,so that students can intuitively see the formation of the three views of the process,easier to lay the foundation.
