High School Mathematics Three-Dimensional Geometry Analysis And Teaching Strategy Research

Three-dimensional geometry is a very important section of high school mathematics.In every year of college entrance examination,there is a fixed score value.The questions of examination and how to learn solid geometry are subject to the attention of teachers and students,so this article is for high schools.It is of great significance to analyze the test points of mathematical geometry and give corresponding teaching strategies.This article focuses on the three-dimensional geometry test questions of the mathematics curriculum standard II of the liberal arts college entrance examination 2013-2017.It mainly analyzes the questions and distribution of scores and the horizontal and vertical distribution of knowledge points.The analysis concludes that:(1)Test questions tend to be stable in the design of questions,and focus on the examination of knowledge;(2)Emphasize ability and thinking,and provide a broad space for students’ potential;(3)Each of the liberal arts and sciences has its own emphasis.Mastery of basic knowledge and basic skills.Questionnaires were used to understand the specific conditions of the student’s learning of the three-dimensional geometry,and after the classification of the survey results,the students’ problems in learning the three-dimensional geometry were concluded.The following are summarized as follows:(1)The academic ability of the three-dimensional geometry subject is exactly what the students are Usually solve the lack of three-dimensional geometric problems,such as computing ability,logical reasoning ability,spatial imagination ability;(2)students’ lecture efficiency is affected by the teacher’s lecture style and style.Based on the detailed analysis of the high test questions,the investigation and analysis of the student’s learning three-dimensional geometry situation,put forward the corresponding teaching and learning countermeasures.From the perspective of solid geometry knowledge,this paper makes a detailed analysis of the three-view problem,circumcision problem,volume problem,parallel vertical determination problem,and included angle problem.From the perspective of stereoscopic geometry teaching,teachers need to actively improve teaching.Effectiveness and conscious training of students’ abilities.
