Analysis Of Triangle Problem-solving And The Research Of Teaching Strategy Under The Background Of New College Entrance Examination

With the reform of the new college entrance examination system,more and more provinces have begun to implement the new policy.After the abolition of science and arts in the new college entrance examination reform,the arrangement of high school mathematics textbooks has also been adjusted,some contents have been deleted,and the types of high school examination questions have also changed,such as multiple choice questions,bad structure questions,scheme selection questions,material background questions and other new types of questions.Among them,the structure-related problems of the 2020 New College Entrance Examination Mathematics Volume 1 and 2 and Beijing Volume are about solving triangles.Every year the high school examination questions will examine the solution of the triangle content,and the examination type is not limited,the examination method is flexible and changeable.Therefore,the majority of teachers and students pay special attention to its examination content,problem solving ideas,teaching strategy exploration.Based on this background,many scholars have studied the changes of the mathematical question types of the new college entrance examination from different perspectives,but few papers have studied the solution triangle from the perspective of the new college entrance examination.This article from the new college entrance examination solutions for the new topic this Angle of the triangle,through literature research,comparative research,questionnaire investigation,interview method,the new college entrance examination before and after a solution of the triangle test question characteristic,analyses the influence students solving triangle new topic(full text refers to the new college entrance examination in 2020 bad problem solving triangle structure)factors,to solve the problem and the students to learn some basic situation and the existing difficulties of triangle.Committed to explore the characteristics of thesis,reveals the problem solving triangle test characteristic,to the university entrance exam to guide teaching,help the students develop self-study,thinking and problem solving skills,and more easy to deal with the math test,finally to survey combined with Suggestions for solution of triangle test and teaching,teachers' teaching and students' learning to have certain help.The main body of this paper is divided into five chapters.The first chapter is the introduction.This chapter mainly introduces the research significance,methods and background of this paper.The second chapter is a literature review,which is mainly about the research of solving triangles in college entrance examination and the research of teaching and learning of solving triangles.The third chapter is about 2014-2020 Beijing volume,shandong,hainan volume solution triangle test question carries on the analysis comparison,the first is to investigate high exam in 2020,Beijing volume of triangle new topic was analyzed,and the second is for 2014-2019,Beijing,shandong,hainan volume solution triangle test were analyzed,and finally from the perspective of mathematical thinking methods triangle induction solution topic.The fourth chapter is in the third chapter,the research about the solutions of the high three students on the basis of triangle new topic of current situation of problem solving and learning situation investigation and study,this chapter through the interview method,questionnaire investigation and analysis of high three students in the learning difficulties of the solution when the triangle and the basic situation,using SPSS software for survey data collected in statistical analysis,clear the main factors influencing the students for solving triangle new topic,understand in solving triangle problems still exist in the teaching and learning.The fifth chapter is the teaching strategy of solving the triangle.Based on the results of investigation and research,this chapter puts forward some targeted and implementable teaching strategies for solving the problems in teaching and learning the triangle.The last part is the conclusion,which summarizes the whole text and points out the shortcomings of the research.Through the research of this paper,the following teaching strategies are proposed for the teaching of solution triangle:(1)optimize the teaching method of knowledge;(2)pay attention to the cultivation of students' learning habits and interests;(3)pay attention to the infiltration of mathematical thought and method;(4)Strengthen students' ability to calculate;(5)Give students enough time for cooperation and communication.(6)Pay attention to variant training,improve the student's ability to adapt to change.
