Analysis And Countermeasure Research On Current Situation Of Stereoscopic Geometry Learning Of Senior High School

Steredimensional geometry is an important section in high school mathematics,and also the required content in the mathematics of the college entrance examination.This paper makes this study to improve the score rate of students in the stereogeometric part.This paper,using literature research method,case analysis method,questionnaire survey method and interview method,analyzes the causes of the error and traces the root of the reason,the four problems reflected by the test volume were "wrong error","unclear logic","confusion of theorem nature" and "unclear understanding of spatial graphics".These are representations of student learning disabilities.According to the questionnaire results to analyze the relationship between students ' learning habits and the level of math scores,to explore the internal causes of learning disorders.We found that the results of the questionnaire could explain the four questions reflected by the test volume,among which calculation errors were mainly related to "students ' error correction ability" and "whether students will review and consolidate the knowledge in time";whether the logic was mainly related to "and" whether they are used to independent thinking when learning ";the mastery of the theorem is mainly related to "whether the student will retell the concepts" and"similar mathematical concepts and formulas".Finally,conducting interviews with teachers and students,have a deep understanding of teachers 'classroom structure arrangement and the construction of students' knowledge system.We found that there are three sources for the final origin of students 'learning disabilities: 1.There are problems in the cultivation of students' learning habits;2.There are problems in the teaching link of the theorem nature;3.There are problems in the cultivation of students ' spatial thinking.For the above problems,the author has obtained the following solution strategies through literature review,field investigation,comparative analysis,and targeted interviews:1.In the cultivation of students 'math learning habits,help students set up the consciousness of active learning,to create a learning environment to catch up with students,let students develop diligent thinking,independent thinking,regular summary review,good at discussing learning habits,teachers in the implementation of the appropriate intervention,actively guide,to ensure that the students' degree of execution.2.In terms of the teaching design of three-dimensional geometric concept courses,teachers conduct the concept teaching in the form of combining inquiry classroom and traditional classroom,so that students can experience the process of knowledge generation,and train students with planning and goals under class,and strengthen students ' ability to solve problem solving.3.In terms of the cultivation of students 'spatial imagination ability,teachers guide students to learn from students' cognitive characteristics,and assist students' spatial imagination ability training from students' logical reasoning ability.
