| The problem of moving point in junior middle school mathematics involves a wide range of knowledge,comprehensive strength,and a variety of question types.It usually appears in the final question in the senior middle school examination,as a kind of question type for examinees to divide the difference.However,due to the high flexibility of the topic,students’ grasp of the knowledge is not ideal,and they have no way to start in the face of such problems.Teachers only talk about the topic when teaching,and lack of systematic knowledge.Therefore,the theory of moving point problem is understood in junior middle school mathematics,the author provides relevant problem-solving strategies for students’ learning based on investigation and analysis,and provides some teaching designs for teachers to provide reference based on educational theories.The research background and significance of this paper are summarized in the first part,and through reading the literature,the research status of this paper is analyzed,and then define the research content of this paper.The related concepts and classification of the moving-point problem are introduced in the second part,and expounds the educational theories involved in the research.The third part of the paper investigates the learning status of 112 students in the middle school affiliated to Yan ’an Vocational and Technical College are asked to understand their cognition and self-attitude towards the moving point problem by compiling a questionnaire,and analyze the situation of teachers combining multimedia in teaching and students’ confusion in solving moving point problem.Moving-point problem types are classified in the fourth part of the paper,and then analyzes the characteristics of each type of questions,including the idea of the questions,answer analysis and solving strategies of the same type of questions,to help students draw examples from one another.Based on the questions in the questionnaire,common types of single and double moving point questions are selected,combining modern multimedia technology and relevant teaching theories,some teaching designs are given in the fifth part of the paper,which provides reference for teachers to systematically teach the moving point problems and helps students to establish a knowledge system.This study is summarized briefly in the sixth part of the paper,and points out the shortcomings of this study. |
