Causes And Countermeasures Of Learning Difficulty Of Quadratic Function For Junior High School Students

In the junior high school stage,the quadratic function learned by mathematics is an effective combination of the knowledge points learned in the whole junior high school stage.It is not an independent knowledge point module at the present stage,and it is also one of the most important and difficult parts.Therefore,it often appears in the examination questions of various provinces and cities,and accounts for a large score,which is designed to examine the ability of students to comprehensively use knowledge and solve complex problems.However,many students are always helpless in the use of this part of the knowledge,and there is no specific solution to the teaching of teachers.As a result,most students are not very satisfactory in this aspect.Therefore,this study conducted a survey on the quadratic function problem involved in the junior high school stage,and analyzed the difficulties and causes of solving such problems based on the survey results,and made reasonable reference to the actual situation of the student questionnaire and the actual situation of the teacher interview.Learning and teaching advice and skills can not only provide effective teaching programs and improve the quality of teaching,but also have an important impact on improving students'thinking style and analyzing their ability to solve such comprehensive problems.Firstly,based on the reference literature,through the cluster analysis of the existing research content,the existing research results are summarized,and the research contents and methods are obtained.Then through paper test,oral question and answer,questionnaire and other scientific research methods,300 junior high school students and dozens of mathematics teachers from A and B schools in the city were surveyed,and Excel2013 was used for statistical analysis and analysis.The main difficulties that need to be solved for quadratic functions are:the concept of quadratic functions,the representation of symbolization of quadratic functions,the representation of the definition of quadratic functions,the image and properties of quadratic functions,the translation of quadratic function images,Solve the problem of the quadratic function application problem and the quadratic function comprehensive application result.According to the analysis of the survey,it is concluded that junior high school students are difficult to solve the quadratic function problem:students,the basic knowledge is not solid enough,the concept understanding is not deep enough,there is no overall grasp of the function,the reading ability is poor,can not be accurate Understanding the meaning of the question;there is fear in the quadratic function,and there is no confidence in building;in terms of teachers,the utilization of information technology in multimedia in the actual teaching process is low,lacking the connection with a function;The function is not paid enough attention,and the exam-type after-school exercises are not mentioned in the exam.After clarifying the specific difficulties of the secondary function learning of junior high school students,the author based on the theory and method of mathematics learning,using the theoretical knowledge of pedagogy and educational psychology,combined with the research and analysis results,put forward corresponding countermeasures,in order to junior high school.First-line teaching and students provide reference to provide students with effective solutions and recommendations.
