The new curriculum standard proposes to cultivate students' innovative consciousness and ability. The spirit of the new curriculum standard must be people-oriented, fully develop students' potential, and let different people get different development in mathematics. In mathematics learning, not everyone can develop in a unified way. Social environment, family environment and many other factors make people have personality differences in learning. Admitting differences can be combined with reality. Admitting differences can make different people develop differently, so that each student can give full play to his talents and get the mathematics knowledge he deserves and can get. Therefore, mathematics teaching should be stratified according to students' personality characteristics, which can better teach students in accordance with their aptitude, develop students' thinking ability, and then improve teaching effect quickly. Personally, I have learned from many years of junior high school mathematics teaching practice that the teaching effect of hierarchical teaching is better than that of traditional non-hierarchical teaching, and the hierarchical teaching in each grade is not exactly the same. Next, I will talk about the hierarchical teaching of mathematics in grade three according to my teaching experience in grade three in recent years.
First of all, on the basis of fully understanding students' mathematical knowledge and thinking ability, students are stratified according to their mathematical knowledge and thinking ability, and different levels of teaching objectives and teaching strategies are formulated according to their different levels. Because junior high school faces the senior high school entrance examination, each student's goal is different, so I usually divide students into three levels. Stratification mainly refers to students' grades and learning conditions. Firstly, all students are ranked according to their grades and divided into three theoretical levels. Level 1: Good math foundation and strong thinking ability. The second level: average math foundation and average thinking ability; the third level: poor math foundation and average thinking ability.
Stratification of target strategy
After students are stratified, teaching objectives and teaching strategies at different levels should be formulated for students at different levels: on the one hand, students should have a solid mathematical foundation, cultivate their mathematical innovation ability, encourage them to ask mathematical questions, and let them learn and solve multiple problems by themselves; On the other hand, we should fully mobilize their enthusiasm, make them master basic mathematical knowledge and gradually cultivate basic mathematical skills. Three-level multi-patient counseling education encourages students to ask as many questions as possible to improve their interest in learning mathematics, and requires them to complete their homework and strive for qualified results in the exam. Hierarchical teaching is to let students know their own mathematics learning situation and find a suitable position, and then teachers apply different teaching methods according to their different situations, so that different students can get different education and the same development rights in mathematics learning, so that every student can make progress. Highlight the word "excited" to junior one students, encourage them to explore and study mathematical problems, and cultivate innovative consciousness; Highlight a "push" to second-tier students, give him a push, and let him get on the road as soon as possible in mathematics learning; Highlight the word "help" to the three-tier students, so that they can learn to learn mathematics and have confidence in mathematics learning.
Second, the hierarchical lesson preparation
In order to make students better master mathematical knowledge and cultivate mathematical thinking ability, every math class should be carefully designed: how to solve the teaching objectives and teaching strategies of students at all levels; In order to achieve the teaching goal, how to create problem situations and how to design in-depth questions for students to explore and discuss; How to decompose the combination example; Where to explain and where to explore. For example, the teaching goal of "quadratic equation in one variable" can be defined as: * * * The goal is consistent: the quadratic equation in one variable can be listed according to the size relationship in specific problems, and the quadratic equation in one variable can be solved. According to the quantitative relationship in practical problems, we can use the quadratic equation of one variable to solve practical problems. The requirements are different: first, we can combine the knowledge of quadratic equation with the knowledge of inequality and function, and skillfully use it to solve some flexible and comprehensive problems with certain difficulties. The second layer: can solve the quadratic equation of one variable, can list the quadratic equation of one variable according to the quantitative relationship in practical problems, and can use it to solve some slightly complicated problems. Three layers: can solve simple quadratic equations, and can list quadratic equations according to the quantitative relationship in practical problems to solve simple problems.
Grade three (2) Mathematics teaching experience Time flies, and a semester has passed in a blink of an eye. Now I will summarize the gains and losses in this semester's work as follows:
First, relying on collective wisdom to create a good teaching and research atmosphere,
One person's strength is limited, and the collective strength is infinite. The excellent performance of a class cannot represent the overall level. Only when the overall level is high can it really be brought into play. Our math group is a United and enterprising group. Eight teachers support and encourage each other, and the class collective activities are carried out vividly, with good quality and quantity. Everyone conducted academic exchanges and discussions without reservation, helped each other, learned from each other's strengths, and effectively ensured the quality of teaching and scientific research. On the basis of unity and cooperation, we also emphasize personal responsibility, avoid eating "big pot rice" and set corresponding goals according to the actual situation of each class. In our minds, there is only the concept of team fighting, not the idea of fighting alone. "It is not spring to stand out from the crowd, but it is spring to let a hundred flowers blossom".
Second, grasp students' psychology and create a good teaching environment.
The cruelty of college entrance examination competition brings about the grim situation of college entrance examination. The resulting pressures have made students' weariness of learning stronger than ever. No matter gifted students or students with learning difficulties, their learning is passive. Students are the main body of learning, and the initiative of the main body has not been mobilized. No matter how hard our teacher tries, it is useless, which forces us to study the students' psychology and find out the teaching methods suitable for their psychological characteristics.
We divide students into three levels and determine our work priorities and measures: eugenics-expansion; Middle school students-pay close attention; Students with learning difficulties-counseling. Eugenics has good thinking habits. Before class, we give them questions to learn and improve their ability to solve problems by themselves. In class, we use discussion teaching method to let them stretch their views, and then the teacher summarizes, deepens, analogizes and improves, and puts forward requirements from three aspects: high, strict and difficult. Middle school students are a large group, and they are the mainstream of learning in ordinary classes. We focus on them in class and try to digest all the knowledge points in class. Homework and exercises are also based on basic questions, and training is strengthened and generally improved. For the poor students, we try our best to improve their psychology, influence them ideologically with love, help them patiently in their studies, compile the topics that these students can complete in class, let them have something to do in every class, gain something in every class, and arouse their enthusiasm for learning.
Mathematics is an abstract subject. To maintain students' interest in learning, we must attach importance to emotional communication with students. For example, timely counseling for students; Remind students who are not focused in time; Give timely praise to students who have good solutions; Give timely psychological comfort to students who lose confidence; Give spare students the opportunity to learn all kinds of abilities and develop their potential. Only when teachers and students have full emotional communication can teaching be completed in a pleasant, competitive and cooperative environment.
Third, strengthen the study of teaching materials and create high efficiency in classroom teaching.
The main channel of implementing quality education is classroom teaching, and the key to improving teaching quality in a large area is the high efficiency of each class. To win the senior high school entrance examination, we must start from the first day of junior high school, and it is very important to lay a good foundation. The school gives us the same teaching time as other subjects. Time is tight and the task is heavy. To "intensive", the requirements for teachers are very high. We pay attention to guiding students to digest concepts, theorems, formulas and laws; Pay attention to students' knowledge defects and difficult problems; Pay attention to the contrast between old and new knowledge, new questions and old questions, and solve complex and abstract problems coherently; Pay attention to the extension of problem-solving methods and explore the law of problem-solving; Pay attention to the study of solving problems with multiple solutions and changeable conditions; Attach importance to thoughtful new problems and explore and study with students.
"Practice" is also the focus of our later work. We basically guarantee more than 30 minutes of practice time in each class. The exercises must be carefully crafted and close to the senior high school entrance examination, which is representative: understanding concepts and consolidating the basic problems of theorems; Ability to use knowledge; Thinking about multiple solutions to one problem; Common problems that are easy to make mistakes; The improvement of comprehensive analysis and so on. Through a series of intensive exercises, students' problem-solving accuracy, adaptability and skills will be greatly improved.
The senior high school entrance examination is a tough battle. To fight this tough battle well, you can't storm, you can only outsmart. We must constantly face and solve the objective problems and earnestly follow the education and teaching policy. Collective wisdom+individual efforts = success.
For a semester, through unremitting efforts, my class has been among the best in the school's competition with Kobe. However, achievements have become history. In the future teaching work, I will start from scratch, constantly study the new situation and new characteristics, make continuous efforts, learn from various schools, learn from various disciplines, and learn from my peers, and make due contributions to our education work.
Experience of Mathematics Teaching in Grade Three (3) The senior high school entrance examination is a key point in students' life. Since a semester, I have been busy with students, sharing weal and woe, and dare not neglect teaching, because I dare not delay students or children. As a teacher, I feel a great responsibility. The work of this school year is summarized as follows:
1, improve the relationship between teachers and students and help students grow up healthily.
I know that one of my basic duties as a teacher is to train students to be useful to society in the future. Therefore, as a junior high school teacher, it is still our most important and main task to let children grow up physically and mentally. At work, I pay attention to the harmonious relationship with students, because I know that students can only "believe in their way" if they "kiss their teachers". Communicate in time to solve some abnormal phenomena of students, such as a classmate's homework is overdue, a classmate's grades are not good, a classmate's mood is low, and a classmate is sick and unwell. I will have a heart-to-heart talk with students in time, and I will also communicate with the class teacher or other teachers to seek measures to make students progress faster and study happily. When students improve their grades or perform well in a certain aspect, they will also give praise and encouragement in time, and the teacher's joy is beyond words. Especially in the third grade, students are under intense and busy study pressure, which comes from heavy study tasks, expectations of parents and teachers, and competition among classmates. Students' mood fluctuates greatly, and catching up with the unique panic and impulse of students who have just entered adolescence requires teachers' attention and guidance.
Making a feasible plan is the guarantee to complete the task.
I made a goal plan in the third grade, and I also made a short-term small goal plan. Small goal plan includes every monthly exam, weekly teaching goals and progress. /kloc-at the end of the new class in week 0/2, the first round of review plan was made in detail. The specific requirements are: clear direction, correct method, careful preparation of lessons, in-depth excavation, accurate selection of materials, powerful examples, accurate narration, clear thinking and practical results.
3. Do a good job in daily teaching.
Make a teaching plan carefully, pay attention to the study of teaching theory, prepare lessons and give lectures carefully, take an active part in group activities and lesson preparation activities, have a good public class, often listen to teachers' lessons, learn from them, learn from each other's strengths and improve their teaching business level. Each class stands on the podium in the best mental state and faces the students with a cordial, relaxed and serious image. Teaching according to the middle school mathematics syllabus, so that students can master the subject knowledge. We also pay attention to the cultivation of good moral character and noble personality based on morality and combined with the phenomena in real life in many aspects and angles.
Finally, we can make a good review plan, prepare lessons carefully, train top students, improve middle students and help poor students. However, due to the short teaching time and more review contents, the review is relatively hasty, and at the same time, it is found that a considerable number of students are not very good at computing and have low learning consciousness. This requires that in the future teaching work, efforts should be spent in peacetime.
4, love poor students, and truly be emotional.
Love poor students, I really move people with emotion: first of all, we must be "sincere", that is, we dare not have the slightest hypocrisy and deception in front of students, as promised; Secondly, we should "accept", that is, we can feel all kinds of psychological expressions and opinions of poor students in the learning process, such as fear, hesitation, satisfaction, indifference, wrong ideas and accusations, trust poor students and encourage them to discuss freely. Finally, the word "understanding" is achieved, that is, seeing things through students' eyes. Because I can understand them kindly and accept them happily, I have promoted the progress and development of poor students to varying degrees. Education is a caring cause. In order to cultivate the next generation with high quality, I have been paying attention to the physical and mental health of students and giving guidance according to their personality characteristics. For some poor students, I use many conversations between classes to encourage them to establish a correct learning attitude and face life positively, while for gifted students, I educate them to guard against arrogance and rashness, make persistent efforts and create new achievements. Through the example in real life, let students set up their own ideas, develop themselves consciously from the aspects of morality, intelligence, physique, beauty and labor, and set up lofty and lofty ideals.
In the future teaching work, we should constantly sum up experience, strive to improve our teaching level, and make more efforts in strengthening the counseling of individual poor students. I believe that all problems will be solved, and I also believe that efforts will always pay off!
I recommend it carefully.
