| With the development of education reform in recent years,more and more people attach importance to education,junior middle school students mathematics is an important part of the entire learning career.For students,second day mathematics learning is a watershed,class polarization serious.According to the years of teaching experience,I found that students' math scores and the difficult degree of students' learning mathematics and their grasp of math classification discussion methods that are closely related.So I set my education of master thesis topic is: junior high school students mathematics classification discussion methods using case studies.Hope that through this thesis research can to deeper understanding of students,improve teaching methods,hoping to reduce the difficulty of the students study mathematics degree,improve the students' math scores.This paper take the survey teaching class students discuss for understanding of mathematical thinking,hope that through analysis on behalf of sexology eugenics,middling,poor student with a math problem solving purpose,understand the different levels student's mathematical thinking,analysis their master degree of the classification discussed thinking,understand the difficulty in mathematics learning process,so as to reflect on the lack of teachers in the teaching process,and improve the back of the teaching.In the back of the do it according to their aptitude in the teaching process,and more targeted teaching,make each kind of level of students can play to their maximum potential,improve the level of the students' mathematical learning ability.In this paper,by comparing various levels students applying the idea of classification discussed the basic situation,understand the learning eugenics,middling and poor student thinking and the characteristics of different mode of thinking,to improve the teaching plan,after have important help to improve teaching quality.In the process of investigation found that learning eugenics to grasp more thorough discuss on it,flexible thinking,can independent analysis and the lines.And middling thinking is relatively limited,in the classification prone to repeat or omission of information classification,fear of serious at the same time,the lack of independent thinking and exploring spirit.Poor student in mind haven't discussed ideas,the concept of classification,the classification discussed ideas without consciousness,not form a right consciousness.In the presence of the above students,put forward the following some Suggestions for teaching,for all students,the mathematics teaching has two lines: a bright line,namely mathematical knowledge.A dark line,namely mathematics thinking method.The training throughout the teaching has always been the method of mathematical thinking,fully reveal the mathematical thinking process.Will "found in the process of mathematics teaching students,let students really become the study master,and teachers just play a dominant role in the process.In the process of mathematics teaching from the following several aspects to help students master the classification discussed thoughts.(1)discuss infiltration in concept teaching consciousness,classification of junior middle school students discuss consciousness is not strong,therefore needs the teacher teaching material establishment situation,strengthened,induce students' positive thinking.(2)in law,theorem,formula embodies classified discussion of ideas,many definitions in the textbooks,theorem,formula is itself a classification definition,classification of,therefore when teaching in teachers can guide students to gradually realize the classification discussed thoughts.(3)in the process of problem solving law and strengthen classified discussion thought.In the process of problem solving not only needs mathematical knowledge and skills,but also should have clear their thinking.Therefore in the process of problem solving experience should guide students to understand the mathematical thinking in math problem. |
