How to build an efficient junior high school mathematics classroom: 1. Change the concept role and promote the relationship between teachers and students.
1, from imparting knowledge to improving ability.
Throughout the ages, there are many classic theories about teaching activities, such as? Learn from each other? 、? Don't teach in class 、? Teaching uncertainty? . But what about reality? For a long time, our mathematics education has a huge potential market and occupies a leading position in the national exam-oriented education. Therefore, despite the trend of promoting quality education and speeding up curriculum reform, our teachers still pay attention to imparting mathematics knowledge by books, ignoring the cultivation of students' innovative spirit and practical ability. The stumbling block to reform is none other than our grass-roots classroom! The new curriculum has changed the tendency of paying too much attention to knowledge transmission, emphasizing that the starting point of teaching should be conducive to the physical and mental development of students, the cultivation of students' ability and quality, and the formation of students' positive learning attitude and interest in learning knowledge. The new textbook changes the complexity, difficulty, bias and obsolescence of the old textbook system, and increases the content of ability training such as exploration and practice activities, so that students can explore the unknown world, mathematical thoughts, mathematical spirit, mathematical thinking mode and the spiritual quality of being brave in exploration and innovation besides mathematical knowledge. The teaching goal of the new textbook no longer focuses on knowledge acquisition, but pays more attention to students' skills and methods of learning knowledge and their ability to adapt to society.
2. From the dignity of being a teacher to being a teacher and friend.
Some teachers still exist? Teacher dignity? The traditional concept of treating students often can't help but play an authoritative role, always condescending to accuse students, who can only obey absolutely and can't ask questions. Teacher-centered, unable to treat students equally leads to tension between teachers and students. At the same time, some teachers lack art in teaching management and ideological exchange. The practice of replacing teaching with management, blocking and teaching with approval has dampened students' self-esteem, widened the distance between teachers and students, and caused students' closed psychology or rebellious psychology. How to build a new relationship between teachers and students in the new era? Respecting students is the premise, studying students is the foundation, helping students is the bridge and trusting students is the key.
Second, create a relaxed environment and cultivate interest in learning.
1. Try to create a relaxed and happy environment.
In recent years, although there have been some changes in the problems existing in classroom teaching, due to the logical and theoretical characteristics of junior high school mathematics and the long-term influence of exam-oriented education, some teachers still cannot get rid of the shackles of traditional educational ideas. Often, teachers show less, teaching AIDS and learning tools are used less, and students do less. They are not learning, but teaching, not practicing. Dull mechanical imitation replaces vivid and meaningful learning, which leads to a cold classroom atmosphere and some students are learning mathematics. Therefore, creating a relatively relaxed and free mathematics classroom atmosphere can stimulate students' initiative and enthusiasm in learning mathematics. Before taking a new class, teachers should make good preparations before class and arrange the classroom process; In the classroom, we should join some links that students can freely play and discuss, sincerely encourage students, and pay special attention to praising some innovative remarks of students; After class, teachers should communicate with students more, be familiar with each student's personality characteristics, and look for their bright spots and correct guidance methods. Based on this harmonious relationship between teachers and students, creating a relaxed and free learning environment will help students' mental development and improve classroom learning efficiency.
2. Cultivate students' interest in learning mathematics from all directions and angles.
Teachers can cite examples related to mathematics in their lives around mathematics problems, so that students can feel that mathematics is around them, thus stimulating their interest in exploration and weakening the boredom of mathematics knowledge; You can also combine the application of mathematical knowledge with practice, so that students can realize that mathematics is useful, and students will have a sense of accomplishment after applying what they have learned to solve practical problems, which will encourage students to have a strong interest in mathematics, so as to learn and study mathematics spontaneously; It can also tell students the correct learning methods, guide students to discover the rules of using mathematical knowledge, improve students' learning efficiency, gradually integrate knowledge, form their own abilities, and maintain students' interest in learning mathematics; You can also use modern teaching methods to present the mathematics teaching process in an image that students love to see and hear, so that students can plug in the wings of imagination and deepen their understanding of what they have learned. Moreover, modern teaching methods can stimulate students visually and audibly in all directions, making them feel more immersive, empathetic and interested in learning.
Third, lay a solid foundation for autonomous learning and explore breakthroughs in cooperation.
1. It is better to teach people to fish than to teach them to fish.
From the perspective of epistemology, the teaching process is the process of students' active cognition. In this cognitive process, knowledge and skills are the objects of cognition, and students are the subjects of cognition. To improve the teaching quality, we must give full play to students' main role. In junior high school mathematics teaching activities, teachers should not only teach students the basic knowledge of mathematics, but also guide students to master the methods and skills of doing problems. Teach people to fish, just for a meal, teach people to fish, and benefit for life? . Enlightening and guiding students' autonomous learning is an effective way to give full play to students' main role. Mathematics Curriculum Standard for Compulsory Education points out that teachers should stimulate students' enthusiasm for learning, provide them with opportunities to fully engage in mathematics activities, and help them truly understand and master basic mathematics knowledge and skills, mathematics ideas and methods in the process of independent exploration and cooperative communication, so as to gain rich experience in mathematics activities. ? Therefore, we should carry out autonomous learning classes, give full play to students' initiative, and let students find the pleasure of exploring mathematics in the process of independent thinking and analysis. We teachers should adopt the teaching mode of learning before teaching, so as to achieve the real goal? Give students the stage, the right to speak, the space, the freedom and the interest? Gradually close the distance between students and math textbooks.
2. It's better to say clearly that teachers cooperate with them to explore.
Reasonably design teaching plans, use scientific learning methods to guide students to participate in cooperative learning activities scientifically and reasonably, and be good at designing valuable questions to guide students to explore, communicate or discuss cooperatively. Enrich classroom teaching forms, stimulate students' interest, activate classroom atmosphere, solve practical problems and improve classroom learning efficiency. Teachers' problems in the process of preparing lessons are too simple and lose the significance of inquiry; The problem is more difficult. Teachers should organize students to explore and communicate step by step, so as to solve the problem and get a preliminary conclusion. Teachers should firmly grasp the teaching materials, reasonably arrange cooperative inquiry links in classroom teaching according to students' cognitive level, grasp the breakthrough point of cooperative inquiry learning activities, and guide students to cooperate, communicate and explore sublimation on the basis of students' basic views on major issues in learning activities. In the classroom teaching, students have a heated discussion on some issues. If there is no cooperative inquiry in the teacher's lesson plan, you can also arrange cooperative inquiry at random, which often leads to unexpected gains.
How to build an efficient math classroom in junior high school? 1. Knowing students and teaching students in accordance with their aptitude is the premise of efficient classroom.
1. Understand students' personality.
Most students like to be praised by their teachers in their studies. Therefore, regular small-scale competitions can stimulate their interest in learning, enhance their sense of competition, and let students advance together in the competition. In teaching, all kinds of competitive means are adopted to stimulate students' interest in learning and enthusiasm for active participation, so that all students can make progress together.
2. Understand students' original cognitive basis.
When anyone is learning new knowledge, the old knowledge must always be involved. Learning new knowledge with existing knowledge not only improves the content of classroom teaching, but also eliminates the invalid space in the classroom and reduces students' learning obstacles. Teachers should ask questions from reality as far as possible, so that students can understand that mathematical knowledge comes from life and is applied to real life, so as to realize the role of mathematical knowledge in real life; At the same time, teachers should also provide students with more opportunities to extract mathematical problems from concrete examples in daily life and use the learned mathematical knowledge to solve many practical problems in real life.
Second, adequate preparation before class is the condition of efficient classroom.
According to the physical and mental characteristics of students of different ages, the new curriculum standard has made scientific and specific provisions on the teaching objectives of different classes. 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. 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.
Thirdly, optimizing classroom teaching process is the key to efficient classroom.
Mathematics curriculum standard points out:? Effective mathematics learning activities cannot rely solely on imitation and memory. Hands-on practice, independent exploration and cooperative communication are important ways for students to learn mathematics. ? And efficient mathematics learning activities should be a higher level pursuit on the basis of effective mathematics learning activities.
1. Guide and show the goal before class.
Fascinating introduction can awaken students' thirst for knowledge and stimulate their interest in learning. Therefore, as soon as the teacher enters the classroom, either let the students listen to the recording or music related to the text, or tell a short story related to the text, or start a wonderful dialogue related to the text, or import it with video clips. So as to stimulate students' interest and motivation in learning and improve classroom efficiency.
2. Develop an outline to guide self-study.
Write a small blackboard before class, so that students can see it in class and make clear the requirements of self-study, that is, what to learn, how long it will take, how to take the exam, etc. And guide students to learn independently, such as reading, whether to read independently around thinking about problems and finding answers, or to discuss and solve difficult problems while reading. As for the proposal of learning objectives and self-study requirements, the best way for junior students is to stimulate competition, because competition can stimulate children's thirst for knowledge and stimulate students' enthusiasm for learning.
3. Group discussion and cooperative inquiry
Cooperation has increasingly become an important quality of contemporary people and is favored by everyone. Group cooperative learning in class is conducive to emotional communication and information exchange between teachers and students, and encourages students to observe and think from different angles, thus developing divergent thinking and seeking the opposite sex.
Fourth, classroom questioning should be oriented.
In the realistic and normal mathematics classroom teaching, it can be said that the problem runs through. Therefore, teachers must attach importance to the study of classroom questioning if they want to complete classroom teaching tasks efficiently. The questions raised must be valuable, enlightening and difficult, and the problem design of the whole classroom must follow the principle of step by step.
Fifth, cultivating good listening habits is the first condition of efficient classroom.
To build an efficient classroom, we must first change? A classroom full of lively speeches? For what? A classroom that listens attentively? . Only in? A classroom that listens attentively? Only by speaking can all kinds of thoughts and emotions communicate with each other, otherwise communication will not happen. Listening to students' speeches is like playing baseball and pitching with students. Accurately catch the ball thrown by the students. Even if the student who threw the ball didn't say anything to you, he was in a happy mood. As a teacher, you should be good at catching every ball thrown by students, especially the ball that students throw badly or miss, which is also the best performance of your own professional quality and ability to control the classroom.
Sixth, the classroom atmosphere should be harmonious and democratic.
Psychologists find that people's thinking is at its best in a relaxed atmosphere. Teachers' friendly smile, moderate humor, encouraging language, equal interaction between teachers and students, and small games all help to create a good atmosphere. Teachers must abandon? Teacher dignity? Traditional ideas, abolished? Patriarchy? Our teaching style should be to appear as a student guide in classroom teaching, with amiable attitude, democratic and decent style and full respect for students' dominant position. Let students express different opinions and ask different questions, and let students dare to ask questions and question.
In order to improve the effectiveness and efficiency of classroom teaching, we must base on? All for the development of students? Under the guidance of teaching theory, through our own continuous practice, continuous summary, continuous improvement and innovation, we can really improve the quality of classroom teaching and students' learning efficiency.
