Study On Common Question Types And Problem Solving Strategies Of The Quadratic Function Finale Questions Of The Middle School Entrance Examination

The senior high school entrance examination is an important means to assess students' academic performance,which is an important basis for the selection of the students in the ordinary high school.Only students across this ridge and they will have a greater wish to pursue their dreams.Mathematics is a subject with a large proportion in the subjects of the senior high school entrance examination and the last big question in the mathematics test of the senior high school entrance examination-the finale problem(here specifically refers to the quadratic function finale problem)determines whether the students can get a high score in the middle school mathematics test.It can effectively test the mathematics ability of all aspects of students,so that there is a certain gap in the math scores of students.During the test of the senior high school entrance examination,from the perspective of students' answering the finale problem,students often give up or partially answer and after the end of the senior high school entrance examination,it was found that the students' performance was not optimistic,mainly because the scoring rate of the finale problem was lower.Therefore,in this article,we give an analysis of the last question from the test papers in Bijie City for the past five years.It is found that some problems of the common problem type of the finale always appear frequently in the quadratic function finale.From the perspective of solving problems of these problems,we will make certain suggestions for students.Starting from the teacher's instructional design,it also makes small suggestions to the coaches.We hope to provide some help to the students and teachers in the senior high school entrance examination.Through the analysis of the test questions and answers,this study draws four conclusions on the quadratic function finale: through the analysis of the test questions and answers,this study draws four conclusions on the quadratic function finale: the coverage of knowledge is getting wider and wider,the focus of the examination is becoming more and more consistent,the senior high school entrance examination is increasingly demanding on students' ability to develop their thinking and their ability to comprehensively apply their knowledge,the mastery of students' basic knowledge and basic skills is getting higher and higher.And on this basis,put forward the corresponding strategy for the candidates of the senior high school:(1)students need to master the basic knowledge that is easy to appear in common questions;(2)students need to master the basic skills involved in common questions;(3)students need tograsp the problem-solving ideas of common question types.For coaches:(1)Students master the basic knowledge that is easy to appear in the types of common que stions;(2)teachers should pay attention to the diversification of methods for solving the finale problem;(3)teachers should use a variety of teaching methods to enter the classroom;(4)teachers should develop the teaching habits with precise teaching progress;(5)teachers should develop good study habits for students.
