Analysis And Teaching Strategy Of Junior High School Mathematics Learning Quadratic Function

Quadratic function in junior high school mathematics occupies a very high position,quadratic function synthesis questions are the finale of the provincial examinations,the main test is the students learn mathematics integrated application ability.Functions are an important tool for learning mathematics,but also an important tool for learning other natural disciplines,and functions are also closely related to real life.The situation in the quadratic function test is that the students score is particularly low,indicating that the students’ knowledge of the quadratic function is not very good,so it is extremely necessary to find out the difficulties of students in the process of answering the questions.Based on this,the author through reading a lot of literature and their own five years of teaching experience to determine the quadratic function synthesis as the research content,mainly to study the status of the quadratic function in junior high school mathematics,the current situation of students’ learning,the new standards for quadratic functions and the requirements of junior high school textbooks on the quadratic function and the arrangement;study the quadratic function synthesis in the last ten years of the Ningxia secondary school examinations in mathematics,as well as the combination of nine years of students in the simulation test The questions and answers of the ninth grade students’ mock tests and the survey of the ninth grade students’ tests are used to identify the problems;the teaching strategies of the quadratic functions are constructed.The quadratic function problems in mathematics of the last ten years in Ningxia were compiled and analyzed in depth in terms of scores,test points,and methods of answering questions,and the quadratic function problems in mathematics of the last five years were further analyzed.The quadratic function problems in the ninth grade of the eighteenth middle school in Yinchuan,Ningxia,were selected and analyzed in terms of students’ solution process,scores and problems.Through the analysis,it was found that the students had a good grasp of solving the analytic equation of functions in the integrated problems,while they faced more difficulties in the integrated problems of quadratic functions and geometric figures.The main problems are: the basic knowledge is not firmly grasped,if the arithmetic ability;can not properly link the relevant knowledge points;the application of mathematical thinking methods of combining numbers and shapes,classification and discussion and transformation is not in place;can not extract the key interest in the topic,can not do the standard answer.Finally,the corresponding teaching strategies are given for the problems appeared in the students’ answers to the quadratic function synthesis questions,and the quadratic function and graphical area synthesis questions are selected for the teaching design.It is hoped that through the study of quadratic function synthesis problems,effective teaching strategies for quadratic function synthesis problems can be found and provide some help for junior high school teachers’ teaching of quadratic function synthesis problems and also provide reference for the teaching model of quadratic function synthesis problems.
