Efficient classroom learning experience of mathematics —— Under the leadership of the school leaders, the teachers of our school's mathematics group went to xx to participate in the efficient classroom exchange meeting of junior high school mathematics, which benefited a lot and gained great inspiration and insight.
1, have a deeper understanding of the concept of effective teaching and how to achieve effective teaching results. Thinking, mathematical consciousness, thinking and problem-solving skills should be left in math class. In order to achieve effective teaching effect, effective teaching design is necessary. Expert xx explained the structure of effective classroom teaching design for us in detail, including: the design of problem situation; Design of construction activities; Mathematical cognitive design; Design of basic training; Five aspects of extended design. Only such a teaching design can help to cultivate students' comprehensive ability and ability to use knowledge, improve students' mathematical literacy and improve their knowledge structure.
2. Have a further understanding of the choice of situation and the role of situation. Teachers must pay close attention to students' existing knowledge and experience, and design problems should arouse more students' interest and in-depth thinking. The demonstration class of three experts designed the problem situation from the simple to the deep, trying to explore it from different angles and in different ways, which is easy to stimulate students' interest in learning and worth learning and learning from.
3. Cultivate students' habit of listening and speaking. In classroom learning, teachers should not only listen patiently to students' speeches, but also be good at guiding students to learn to listen to others' speeches, because listening and speaking are closely related. Learning to concentrate and listen to others quietly is a sign of respecting others and learning from them. Being with yourself is a process of enterprising thinking activities, and it is the need for further thinking and improvement on the basis of other people's opinions. Some students don't like to talk in class and don't raise their hands when they meet. Only by cultivating students' habit and ability to speak out can we create an independent and efficient learning atmosphere.
3. Build up confidence, give more encouragement and make students feel successful. Because of our study, most students have a poor foundation in mathematics. Teachers should be good at discovering students' respective strengths, give them opportunities to show their abilities as much as possible, and enhance their confidence in learning mathematics well. Fu Yongping, an expert, praised the students many times in the demonstration class and said, "You are really good, and so are the teachers who compile books!" With a sense of accomplishment, students will become more and more confident.
4. Cultivate interest in learning. As a motivational component, learning interest has a self-evident influence on autonomous learning. The stronger the interest in learning, the stronger the initiative and consciousness of learning.
5. Teach students learning methods and establish appropriate evaluation mechanism. Teaching students to learn is to teach students to learn to learn, which is the basis of realizing autonomous learning. Teachers can regard all activities of learning mathematics as resources to guide their learning methods. Appropriate evaluation mechanism is the motivation of students' autonomous learning. In classroom teaching, we should be good at discovering students' bright spots and evaluating their autonomous learning performance.
The real secret of teaching success is to construct independent and efficient classroom teaching, and the key to ensure success is to adopt methods that enable students to learn mathematics in a simple and happy state of mind. In teaching practice, every teacher should constantly explore the effectiveness of mathematics classroom teaching, strive to achieve the optimization of mathematics classroom teaching, pay attention to the development of students, pay more attention to their own development, and truly realize "teaching and learning."
Efficient classroom learning experience of mathematics II. Through some study, I have thought about the effectiveness of classroom teaching, and here I want to talk about my own experience.
First of all, efficient classroom attaches importance to preparing lessons before class.
(1) Carefully determine the classroom teaching objectives. According to the physical and mental characteristics of students of different ages, the new standard makes scientific and specific provisions on the teaching objectives of different classes. This requires us to study the standards seriously and do it in strict accordance with the requirements of the standards when formulating teaching objectives. First of all, the orientation of teaching objectives should be moderate and difficult. Just like playing basketball, the basket is too high, and students can't throw it in no matter how hard they try, so they naturally lose confidence; Moreover, if the basket is too low, students will easily fall into it, and of course there will be no joy in overcoming difficulties.
Secondly, teachers should fully consider the unity of three-dimensional goals when formulating teaching goals. Knowledge and skills, emotional attitudes and values, processes and methods are equally important and indispensable. Thirdly, the formulation of teaching objectives should also consider three levels: good, medium and poor. According to the principle of teaching students in accordance with their aptitude, the formulation of teaching objectives should also vary from person to person, and students at different levels require different goals, so it is necessary to avoid generalizing. It is necessary to ensure that more than 80% of the students in the classroom master more than 80% of the classroom teaching content. For top students, you can extend some slightly challenging exercises after class; For those underachievers, we can also put forward some superficial requirements for them to make them step by step.
(2) Instructional design should pay attention to students' learning process. Preparing lessons is the premise of a good class, so what is the preparation for preparing lessons? The important guiding ideology of preparing lessons for teachers is not to prepare teachers for how to "teach", but to prepare students for how to "learn". Teachers should pay attention to students' learning foundation and learning state and carefully design students' learning process. It is necessary to fully presuppose which part of the content is difficult for students to learn, how to implement it, which part of the content is easy for students to have objections or unique opinions, and how to deal with it.
(3) Creative use of teaching materials. Since the implementation of curriculum reform, teachers have realized that they should "use" teaching materials instead of "teaching" them. Teachers should creatively use teaching materials, change "dead teaching" teaching materials into "flexible use" teaching materials, and make classroom teaching vivid and effective. Creative use of teaching materials is one of the keys to improve the effectiveness of classroom teaching. Teachers should creatively use teaching materials, first of all, on the basis of careful study of teaching materials, according to their own learning situation and teaching needs, improve and supplement teaching materials, so as to better serve teaching and students. Secondly, teachers should be brave in innovation and boldly "reprocess" and "re-create" the teaching materials to make them more suitable for students' reality and improve the effectiveness of classroom teaching.
Second, efficient classroom attaches importance to the effectiveness of classroom teaching behavior.
Classroom teaching behavior is a two-way interactive process between teachers' teaching and students' learning. The concept of curriculum reform advocates students' independent, cooperative and inquiry learning methods, which are all "teaching" behaviors under the organization and guidance of teachers. To improve the efficiency of classroom teaching, it is important to improve the effectiveness of teachers' "teaching" behavior. Therefore, every specific behavior of teachers in classroom teaching should be carefully thought out and designed. How to improve the effectiveness of teachers' efficient classroom teaching behavior? I think:
(1) Teachers should strive to create an equal and harmonious relationship between teachers and students. Teachers should put down the traditional concept of "showing dignity as a teacher" and "lean down" to communicate with students. Only in the harmonious, equal and happy relationship between teachers and students can teachers and students devote themselves wholeheartedly, teachers are full of spirit and scholars are full of interest. This requires teachers to establish a student-oriented view and adhere to the idea of teaching serving students. Teachers should be more clear about their roles, that is, they are organizers, collaborators and participants in teaching activities. In addition, teachers should always remember that students are flesh and blood, living people, not containers of knowledge. They don't passively accept knowledge, but actively construct it.
(2) Teachers should create learning situations to stimulate students' interest in learning. Interest is the best teacher. In teaching, teachers should contact students' reality as much as possible, introduce new mathematics knowledge from life or specific situations, and let students have interest in learning and exploring in effective situations. Teachers should be good at understanding students' learning situation, combine teaching contents, and strive to create various vivid teaching situations to stimulate students' interest in learning and guide students to actively participate in learning. By creating situations, teachers make students have the motivation to learn new knowledge and actively participate in the activities of exploring new knowledge.
(3) Efficient classroom comes from problem setting close to students' life. Starting from the familiar life scene and fairy tale world, try to choose the math problems that students are interested in, stimulate students' interest and motivation in learning, and let them feel the close relationship between mathematics and daily life. In mathematics teaching, teachers should seize the opportunity to create learning scenarios that are closely related to students' living environment and knowledge background, so that students can appreciate the fun of mathematics, generate the need for learning, stimulate the enthusiasm for exploring new knowledge, and actively and effectively participate in learning.
Third, efficient classroom pays attention to after-class teaching reflection.
Teaching has no definite method, and teaching is a regrettable art. A class will not be perfect. Every class should be deeply analyzed and reflected, and the coincidence between presupposition and reality, students' learning situation, teachers' regulation, classroom generation and other aspects should be carefully summarized, so as to find out the regular things and learn through constant reflection. Promote the quality of classroom teaching and the teaching effect will be better.
Fourth, efficient classroom attaches importance to the cultivation of students' study habits.
1, the habit of previewing before class
Preview is not just reading books, but also thinking about some basic questions: what is it? Why? Is this ok? What is the connection with previous knowledge? Wait a minute. In this way, the class will be targeted, the key points will be focused, and the difficulties will be tackled, and the class will naturally have an effect.
2, the habit of classroom learning
In class, we should "listen to the sound, read the words, use our hands and brains, and study hard". Sit on a stool, stand up and stand up straight; See the teacher in class. Some key contents should be outlined in the textbook, and some should be recorded in the blank space of the textbook or in the notebook. The teacher writes intuitively on the blackboard; Teachers should think positively when asking questions, dare to express their opinions, and ask teachers in time if they don't understand questions; When answering the questions in the textbook, hold the book on your chest and speak loudly; When writing, you should write correctly and carefully, the process of writing answers should be standardized, you should write in the specified position, you should not despise typos and other words, and you should independently complete the homework assigned by the teacher; When discussing problems, we should take the initiative to participate and speak actively. We should concentrate on learning only around the teacher's lecture ideas.
3. Consolidate habits after class
Insist on reviewing before doing the questions, consolidate the important link of digesting the learning content when reviewing, and carefully review what you have learned, so that you can remember and understand before doing your homework. If you can review your homework first, and then treat it like an exam every time, that means you have to take the exam several times a day, and you won't fail the formal exam with a score of 100.
Reforming teachers' teaching methods, changing students' learning methods and pursuing high-quality and efficient classrooms are the primary tasks of basic education reform. It is our important task to fully implement quality education, deepen curriculum reform, continuously accelerate the balanced development of education and improve the quality of education and teaching.
Experience of effective classroom learning in mathematics III. Mathematics curriculum standards require students to learn valuable knowledge and practical knowledge, promote students' development and improve the effectiveness of classroom teaching. Efficient classroom means that teachers' teaching ideas must be efficient; What students get must be efficient; The input and output of teaching must be efficient. Efficient classroom can be summarized as effective, efficient and effective. So what problems should be paid attention to in primary school mathematics classroom teaching? Through this efficient classroom learning, I will talk about my own experience below.
I. "Six Emancipations"
(1) Emancipate children's minds and make them think;
(2) Emancipate children's hands and make them capable;
(3) liberating children's eyes so that they can see;
(4) Liberate children's mouths and let them speak;
(5) Liberating children's space and broadening their horizons;
(6) Free children's time, let them have leisure to digest and study, and do what they like. Mr. Tao Xingzhi's profound insights point out the direction for our classroom teaching, that is, building a democratic, relaxed and harmonious classroom, respecting students' personalities, trusting students' abilities, listening to students' voices, making students dare to think and speak, and creating a classroom environment conducive to students' learning and development.
Second, create real, concrete, vivid and interesting problem situations for students.
The new mathematics curriculum standard emphasizes creating problem situations for students in classroom teaching. Its purpose is to let students learn and understand mathematics from their familiar real life, enhance their interest in mathematics learning, and cultivate their thinking ability and mathematics literacy. When creating question situations for students, the choice of questions is very important. First of all, be interesting. Because the purpose of creating question situations is to cultivate students' interest in mathematics learning, if questions can't arouse students' interest in mathematics, such questions are not desirable. Secondly, this question has a taste of mathematics. If there are few or no math problems in the questions, such questions are not desirable. Finally, we should pay attention to challenging problems. It is necessary to have the function of challenging students' thinking, so that students' mathematical thinking can be greatly developed and brought into play. However, we should pay attention to creating problem situations for students, not creating situations for the sake of creating situations, and pay more attention to not creating problem situations for too long.
Third, let students "move" in class and participate in mathematics teaching.
The new curriculum standard emphasizes that students should participate in mathematics teaching, engage in activities, especially thinking activities, and emphasize students' independent exploration, cooperation and communication, and hands-on practice. Compared with the original mathematics syllabus, the orientation of teachers has changed fundamentally. Teachers are the organizers, guides and participants of knowledge students' learning. In other words, the whole teaching classroom should be a place for students to find problems, solve problems, use their brains, do things and innovate. Only in this way can the effect of mathematics classroom teaching be good.
In a word, scientific learning methods are an important guarantee to create an efficient classroom. Under the guidance of the new curriculum concept, we should reform the classroom teaching mode and improve the classroom efficiency under the premise of giving full play to the students' main role.
The experience of efficient classroom learning of mathematics in the fourth grade of primary school is as follows: using as little time as possible, teachers and students make the least effort to get the best teaching effect; In other words, in forty minutes, students get the greatest development, accumulate as much knowledge and experience as possible, and develop their thinking and language comprehensive application ability as effectively as possible. I have a lot of feelings by watching the math observation class in xx school district this afternoon. Let me talk about some of my own experiences in detail:
1. Successfully established an independent and cooperative study group.
Group cooperative learning is the basic form of classroom reform, and group construction is particularly important. Team members should build each team into a spiritual home for team members based on the principles of respect, mutual assistance, promotion and development. Through listening to the class, I found that every student is full of enthusiasm and passion, and can actively participate in and show themselves, light the torch of thinking and show themselves. Can find and solve problems in the process of communication, help classmates and improve themselves. It can be seen that teachers must have made great efforts for the construction and development of the group. Teachers make full use of study groups, let students study and show in groups, and fully understand and use the language they have learned, which is bound to improve students' comprehensive language use ability.
Second, positive classroom display
In the teaching process, teachers should strive to establish a friendly teacher-student relationship of mutual equality, mutual respect and mutual trust, and form a democratic and harmonious teaching atmosphere, so that students can learn in a pleasant, harmonious and relaxed atmosphere. In this class, the teacher asked students to let go of their hands and feet, everyone participated, actively displayed, learned to communicate, learned to learn, and listened well, creating a sunny, harmonious and efficient classroom. Realize the exchange of space for time, replace line with surface, grasp the key points and break through the difficulties. In the exchange and exhibition, students' self-confidence is enhanced, their psychology is stable, their expression is fluent and their thinking is agile; In communication and exhibition, students have a sense of accomplishment and find their own value; It has realized the transformation from imitation learning to autonomous learning, research learning and creative learning, and improved students' analytical ability and thinking ability.
Third, highly targeted classroom test content
The purpose of classroom test is to check the completion of students' teaching objectives in this class. First of all, the design of exercises is very important. We must closely follow the knowledge points tested in the classroom, be targeted, and adhere to the principle of less but better. The design of this class has always revolved around the teaching focus of this class. There are various forms of classroom tests, and students learn solidly.
We may be used to the long-term indoctrination teaching mode, and students' autonomous learning ability is not strong. With this brand-new learning mode, we can't help but shine at the moment. With the guidance of xx school district, I believe that through our own efforts, under the guidance of this brand-new and scientific model, our mathematics teaching will open up a brand-new teaching road.
What is an "efficient classroom"? I think efficient classroom is a classroom with students as the main body and exploration as the core under the guidance of teachers. It is a classroom where students are active and enterprising in a relaxed, democratic and harmonious competition atmosphere, and their knowledge is fully internalized and their skills are fully improved within 40 minutes. So, how to build an efficient junior high school math classroom? Combined with this study, I will talk about my own practice and experience.
First, optimize the relationship between teachers and students and create a harmonious learning atmosphere.
I firmly believe that students can only "believe in their way" if they "learn from their teachers". Concern for students' life, psychological care, spiritual care and help in study have narrowed the distance between us. Often communicate with students about teaching and learning, adjust self-teaching strategies in time, and strive to create a democratic, relaxed, harmonious and competitive teaching atmosphere, so as to stimulate students' independent consciousness, activate students' creative thinking, stimulate students' imagination, and facilitate the collision and exchange of different viewpoints. This is the premise of building an efficient junior high school mathematics classroom.
Second, optimize students' combination and reasonably divide students' learning groups.
1, scientific grouping
At the beginning of this semester, I combined good and poor students, with three people in a group, six people in the front and back rows, and one person in the middle of each group as the leader, following the principle of "heterogeneity within the group, homogeneity between groups". Simple problems are discussed and solved in the group, and problems that the group cannot determine are solved in the same group. If you really can't solve it, please consult the teacher to solve it together and arrange large group activities flexibly in class.
2. Strengthen group management
In order to give full play to the function of group cooperative learning, it is very important to strengthen the management of the group. Before the start of cooperative learning, teachers should make students clear about the tasks of cooperative learning, explain the operating procedures, and educate students on the spirit of group cooperation. At the same time, give the group leader the necessary rights and responsibilities, organize the members of the group to carry out learning activities in and out of class, and the teachers will guide the work of the group leader at any time, cultivate the management skills of the group leader, and ensure the orderly progress of group cooperative learning.
Third, students should pay attention to the problems in group cooperative learning.
1, teachers help effectively
In the process of cooperative learning, teachers should provide timely and effective guidance and help for students. In the process of students' discussion, teachers should go deep into each group to understand the effect of students' cooperation, the focus of discussion and the cognitive process, give evaluation and summary in time when necessary, and praise or reward those who do well.
2. Prompt encouragement and evaluation
In order to fully mobilize the enterprising spirit of the group members, cultivate the sense of unity and cooperation of the group, and give full play to the group role of the group, the group evaluation adopts the bonus system, so that every child has the opportunity to experience success and enjoy the joy of success! Only in this way can we really help the poor in the group and promote together; Teams compete with each other and improve together.
Fourth, guide the learning methods and cultivate students' good study habits.
Mr. Ye Shengtao said: "Education is to cultivate habits". Good study habits will benefit students for life. A group of students who have good study habits, can learn and take the initiative to learn are naturally the most powerful guarantee for an efficient classroom.
However, we must understand that the cultivation of students' good habits is inseparable from the strict requirements of teachers. Therefore, in group cooperative learning, we should pay attention to cultivating students' following habits.
1, the habit of independent thinking
Before organizing cooperative learning, teachers should leave students time and space for independent thinking. Only through independent thinking of problems can students actively provide psychological and material preparation for the construction of new knowledge and cultivate students who are not blindly obedient and have their own unique opinions.
2. Express the habit of communication
In teaching, teachers should create situations, give students the opportunity to speak, let them boldly state their views and opinions in groups, and even argue with their classmates. For example, when learning the power of rational numbers, I created a question: "If the thickness of a piece of paper is 0. 1 mm, what is its thickness after 27 fold? Which is higher than the height of Mount Everest? " Members of each group are enthusiastic, origami, measurement and estimation, and express their opinions! Finally, summarizing the opinions of the group, most people can't imagine that the total height of a piece of paper after being folded in half will exceed Mount Everest. At this time, the teacher began to introduce the new lesson "Power of Rational Numbers". With strong curiosity and thirst for knowledge, the students devote themselves to the new lesson. On the basis of self-study, discussion and practice, they can effectively understand and master the knowledge in this section, and finally solve the above problems by themselves, exchange views and experiences in groups and between groups, further stimulate students' interest in motivation and feel the application value of mathematics.
3. Good habit of listening
In teaching, making students say that many teachers can do it, but making students learn to listen may be mostly ignored. Learning to listen is not only respect for others, but also a clear understanding of the similarities and differences between others and self-thinking, and understanding the central idea of others' speech, so as to improve themselves. Learning to listen and being good at listening methods and habits is an indispensable part of achieving the goal of group cooperative learning.
4, the habit of hands-on practice
Curriculum standards point out that "hands-on practice, independent exploration and cooperative communication are important ways for students to learn". In teaching, the process of doing should be given to students, and teachers who belong to students will never possess it, and teachers who can make students practice will never replace it, so that students can develop the habit of being brave and good at doing it. For example, in the chapter of "Color Graphics", we must give full play to the cooperation efficiency of the group. Through observation, observation and discovery, discovery and thinking, and thinking and summing up the law, the understanding and mastery of knowledge will rise from perceptual to rational!
Fifth, choose the appropriate learning form.
1, discussing self-study
For the materials suitable for students' self-study, they are assigned to each group at the beginning of the semester and tell them the learning objectives. Then, under the leadership of the group leader, learning activities are carried out in different forms, such as central speech, designated speech, pairwise combination, relay cycle, free speech, division of labor and cooperation. In the process of students' self-study communication, teachers should patrol and guide, explain when necessary, praise the group that has made good progress in self-study at any time, and encourage the group that has made slow progress. Ensure that the enterprising spirit of each team member is truly brought into play and form the wisdom of the group.
2. Test competition
After learning a unit, each group will test each other. Members of each group will be assigned a test paper and copied several copies according to the knowledge points. In class, the test papers will be exchanged between groups, completed within the specified time, and then handed over to the other party for correction. According to the quality of each group of questions, teachers test each other's mastery of knowledge, show the competitions prepared before class, judge the rankings, and finally give the results of the group's classroom activities according to the rankings.
6. Stimulate students' interest in learning by using multimedia-assisted teaching.
The application of multimedia in mathematics teaching can give full play to its intuitive, time-saving and large-capacity characteristics and stimulate students' interest in learning. For example, in the teaching of understanding geometric three-dimensional graphics, we choose 3DS 3D animation. In the demonstration, any geometric figure and solid geometric figure are reproduced in three dimensions in the form of images, so that various geometric figures can be presented to students under static and dynamic conditions. This not only stimulates students' interest in learning, but also greatly speeds up students' understanding. This can improve students' initiative and curiosity, make them take the initiative to learn mathematics, and thus improve the efficiency of junior high school mathematics classroom teaching.
In short, I have made necessary explorations in the work of building an efficient classroom in recent years, but my understanding is inevitably superficial and I feel that I have not done it well enough. But in the future teaching practice, I will strengthen the grasp of curriculum standards and teaching materials, further cultivate students' self-study skills and scientific learning methods, constantly sum up and improve, and strive to do better in building an efficient classroom work of junior high school mathematics.
