Investigation And Research On Senior High School Students' Ability To Solve Solid Geometry Problems Based On Core Literacy

The curriculum standards focus on the future national quality and are important teaching guidance documents.Compared with the previous curriculum standards,the newly promulgated “General High School Mathematics Curriculum Standards(2017Edition)” pays more attention to the cultivation of students' core literacy and more emphasis on improving students' ability to use knowledge to solve practical problems.Mathematics is a basic discipline,and its importance need not be repeated.As an important part of high school mathematics,solid geometry mainly studies the basic knowledge related to graphics in three-dimensional space,has a wide range of applications in real life and scientific research,and has an irreplaceable position.However,during a one-semester internship in a demonstration high school in Ma'anshan City,Anhui Province,the author found that there are three major phenomena in the process of learning solid geometry among high school students.First,it is common that students cannot really understand in class;second,students cannot accurately judge the positional relationship and quantity relationship of the graphics space;third,students cannot find a breakthrough in the proof question,and the confusion of argumentation and reasoning.If you understand it,you will make a mistake,and your ability to solve problems will be low.This will make students feel afraid of solid geometry and gradually lose their interest and motivation.Thus affecting further learning.Based on this,the author,after consulting a large number of relevant materials,under the guidance of relevant theories,through questionnaire surveys,student test paper analysis,teacher interviews,combined with his own learning and practice practice,found that restricting students to learn solid geometry and problem-solving skills are the two most important.The most critical factor-low intuitive imagination and lack of logical reasoning.According to the above conclusions,in order to improve the two core qualities ofhigh school students' intuitive imagination and logical reasoning,and improve the ability to solve solid geometry problems,after studying a large number of documents and conducting interviews with famous teachers,the author combines his own learning experience and internship experience to improve the level of educational technology.Optimizing teaching methods and methods,mobilizing students' interest in learning,inspiring students' initiative,self-confidence,improving students 'self-control,cultivating students' perseverance,guiding students from multiple angles of independent inquiry,cooperative communication,hands-on practice,etc.Teachers teaching and students learning put forward specific and feasible countermeasures.Hope to provide reference for teachers' teaching and students' learning.It is helpful to improve students' ability to solve solid geometry problems.
