Research On The Learning Status And Teaching Countermeasures Of Stereo Geometry Subjective Problems

Stereoscopic geometry is an important part of high school mathematics and is the focus of the college entrance examination.The college entrance examination mainly uses three-dimensional geometry as the carrier to test whether students have mathematical thinking methods of combining numbers and shapes,transformation and transformation,functions and equations,reflecting the core qualities of mathematical logical reasoning,intuitive imagination and mathematical operations.In order to improve the score rate of senior science students in the college entrance examination mathematics solid geometry,the author first analyzes the stereo geometry test points of the national paper of the college entrance examination in the past five years,and then uses the mathematics week to investigate and study the current situation of students’ stereo geometry learning in the ordinary class of science in the third year of high school,and analyzes the students’ learning situation and problems in solid geometry,and understands the reasons for students’ learning difficulties through questionnaire surveys,so as to propose effective teaching strategies.Based on the results of the analysis of the stereo geometry test center of the national college entrance examination in the past five years,the author has formulated20 sets of mathematics weekly exercises,mainly for the high-frequency test center of stereo geometry subjective questions to test students and understand the students’ problems in these question types.Through the analysis of students’ problems,the author found that students have six problems:(1)students’ lack of spatial imagination;(2)Students lack knowledge understanding and memory;(3)Students’ logical thinking is not strong;(4)Students’ handwriting is not standardized;(5)Students’ numeracy skills are not strong;(6)Students’ interest in learning is not high.In order to find out the reasons for students’ problems,the author formulated a questionnaire,analyzed students’ problems through the results of the questionnaire,found the main causes,and proposed the following six teaching strategies:(1)improve students’ spatial imagination through intuitive perception;(2)improve students’ understanding and memory through analogy;(3)Improve students’ logical thinking ability;(4)cultivate students’ writing norms;(5)Improve students’ computing ability;(6)Cultivate students’ interest in three-dimensional geometry learning.
