Research On Problems And Countermeasures In The Teaching Of Stereo Geometry In Senior High School

Solid geometry is a discipline that studies the relationship between the size,shape and position of spatial graphics.The status of solid geometry is self-evident.As a branch of geometry,it has always been the focus and difficulty of high school mathematics teachers and students.However,more and more teachers and students report that this part of the content is difficult to teach,difficult to learn,difficult to understand,and students lack interest in learning.Obviously,solid geometry has become an insurmountable obstacle in front of high school students.In order to better solve these problems in high school stereo geometry teaching,this paper will analyze and study the following four chapters.The first chapter mainly introduces the topics to be studied in this paper.The article first introduces the background of the research,including the important position of solid geometry and the teaching status of solid geometry.Then it raises the question to be studied in this paper: What are the problems in the process of solid geometry teaching? What are the reasons for these problems? What strategies should be taken to solve such problems in actual teaching? Finally,the article introduces the research purpose and significance of this topic,the research status and research methods at home and abroad.The second chapter introduces the problems in the teaching of high school solid geometry.The author firstly used the interview method and the questionnaire method to find the problems in the high school stereo geometry teaching.Then the author analyzed the literature research and the survey results,and got the problems of teachers and students in the process of stereo geometry teaching.The teachers are mainly reflected in the following five aspects: First,the quality of teachers is uneven;second,the form of preparation for teachers is single;third,the teaching method is single.;fourth,the teacher lacks the training of students' ability;the fifth is that teachers do not have enough after-school tutoring for students.Students are mainly reflected in five aspects: lack of consciousness,lack of interest,lack of ability,wrong methods,and low efficiency.The chapter concludes with the reasons for the above problems.The third chapter mainly discusses how to solve some difficult strategies for teachers to teach difficult and difficult to learn in the process of three-dimensional geometry teaching.This chapter is mainly divided into the teacher level and the student level.The teachers mainly carry out three major aspects: the quality of the teachers and the classroom teaching and the implementation of the after-school.The students mainly study from the scientific study,independent learning,and 100>N 70 theory.The aspect is to explore and aim to help the teachers and students overcome the difficulty of solid geometry.The fourth chapter is a series of teaching explorations conducted by the author in his own school.The purpose is to test the effectiveness of the teaching strategy.The results show that the teaching strategy proposed by the author is effective and feasible,and has certain reference value.In summary,this paper mainly explores the problems and influencing factors in the teaching of high school solid geometry from two aspects: teachers and students.Based on the theory,the author finds out the problems in the high school stereo geometry teaching through the investigation,summarizes the effective strategies of the high school solid geometry teaching,and then feeds back the teaching in the form of practice,to help the high school mathematics teachers to have a good idea in the three-dimensional geometry teaching.This paper aims to find ways to effectively teach,and at the same time help students adapt to high school geometry learning as soon as possible,to achieve a two-dimensional to three-dimensional transition,and more easily complete high school learning.
