Experience in junior high school mathematics teaching
What exactly is mathematics? Mathematics is a kind of thinking, description, explanation and understanding of the real world. Its purpose is to discover some laws of numbers and shapes contained in the real world and serve the progress of society and the development of mankind. The core problem of mathematics education is the optimization of students' learning process, that is, how to make students learn the required mathematics actively, effectively and reasonably. In the process of mathematics education gradually changing from "exam-oriented education" to "quality-oriented education", we need to renew our ideas, blaze new trails, improve teaching quality in a large area, change the existing educational model and management concept, give students time and space for development, speed up the research and implementation of curriculum reform, and promote quality-oriented education. The following is my experience in the teaching process:
First, let mathematics teaching be linked with real life.
The new Mathematics Curriculum Standard points out: "Mathematics teaching should be closely related to students' living environment, and based on students' experience and existing knowledge, create a situation conducive to students' independent learning and cooperative communication, so that students can master basic mathematics knowledge and skills through observation, operation and induction, develop their abilities, and stimulate students' interest in mathematics and their desire to learn mathematics well. "
Mathematics originates from life, and mathematics in life is the most dynamic, and all teaching and learning that are divorced from the reality of life are powerless. In our life, mathematics is everywhere. Teachers should be good at abstracting mathematical problems from students' lives in teaching, so that life mathematics familiar to students can enter students' horizons and classrooms, make students feel close, become concrete and vivid, induce students' inherent knowledge potential, and let students take the initiative to start work, talk, use their brains and try their best to explore the formation process of knowledge, so as to meet their own life and psychological needs and gain the joy of success. At the same time, it also strengthens the initiative of learning mathematics, develops the thinking of seeking differences, and cultivates the scientific attitude of seeking truth from facts and the spirit of being brave in exploration and innovation. To this end, the author often guides students to provide their own familiar experience, make full use of students' existing knowledge and experience and what they are familiar with to organize teaching, so that students can better perceive and understand what they have learned.
Mathematics learning should be a lively and interesting learning activity, with a broad space for thinking and practice, which students can feel with their hearts. In the past, mathematics learning often made students feel too far away from their own life practice and boring. In fact, mathematics learning can completely extend students' learning scope to their social life and various activities, integrate education with life, and let students get more direct experience and experience. Teach students ways of thinking and habits of thinking, and let them feel the wisdom and beauty of mathematics.
Second, prepare lessons carefully, prepare lessons carefully
Teaching is an art, and preparing lessons well is the basic condition for doing art well. Every class should be "prepared", and every class should be fully prepared before class. To prepare a starting point, the so-called starting point is the growth point of new knowledge on the basis of original knowledge; To prepare the key points, the key points are often the starting point and main part of new knowledge, and to highlight the key points when preparing lessons; Preparing for difficulties, the so-called difficulties, are the knowledge points that most students in mathematics are difficult to understand and master; To prepare the intersection, that is, the connection point of old and new knowledge; Be prepared for doubts, that is, the knowledge points that students are easy to confuse and make mistakes.
Third, cultivate students' ability to learn mathematics independently.
Every student is an independent person, and learning is a student's own business, and teachers can't and can't replace it. Teachers only play a guiding role. The current teaching reform requires changing the simple receptive learning, focusing on the change from "one size fits all" teaching to teaching that pays attention to individual differences, and emphasizing discovery learning, inquiry learning, research learning and autonomous learning. Therefore, it is very important to cultivate students' ability to learn mathematics independently, which not only helps students to master and absorb the required knowledge faster and better, but also helps to cultivate students' exploration ability, problem-solving ability, application consciousness and innovation spirit.
Fourthly, cultivate students' awareness of participation in mathematics classroom.
Mathematics classroom is usually considered as boring, lacking vividness and passion. Therefore, it is particularly important to create a relaxed, humanized and convenient teaching environment for students, so that they are good at thinking and willing to explore. Let students form a correct learning style and attitude towards mathematics in classroom learning activities. Only when students realize the fun of mathematics can students take the initiative to understand mathematics, and mathematics teaching can serve their future development.
The effect of classroom teaching depends largely on students' participation, which first requires students to have a sense of participation, strengthen students' awareness of participating in classroom teaching, and make students truly become the masters of classroom teaching, which is the trend of modern mathematics teaching. To this end, mathematics class should fully "move" students. In other words, students' personality is highlighted, their thinking is active, and their hands and feet are liberated, which will greatly improve teaching efficiency.
Create a democratic and harmonious classroom teaching atmosphere, so that students are diligent in thinking and good at speaking; Cultivate good classroom habits and let students study in an atmosphere of discussion and communication.
For students, good classroom habits mean opening their minds, highlighting their dominant position, displaying their individuality and liberating their creativity. For teachers, it means sharing understanding with students, which is an activity of life, a professional specialty and a process of self-realization.
Five, based on the foundation, to help improve
In junior high school mathematics learning, some students lack good study habits, can't attend classes seriously and continuously, and have short concentration time; Lack of correct mathematics learning methods, just simple imitation and recitation; In class, learning thinking is delayed, which can't keep up with the teacher's thinking, resulting in a tendency to stop thinking and learning; Basic knowledge (theorems, definitions, formulas, etc.) is not well mastered. ) In normal learning, it leads to the lack of coherence and basis for solving problems, resulting in "confusion" and "strangeness" in solving problems; Psychological pressure, afraid to ask for advice, afraid of being considered "stupid", accumulated over time, leading to certain difficulties in learning mathematics.
Students with learning difficulties have both difficulties and potential in mathematics learning. Therefore, the primary task of teaching is to change ideas, treat students with learning difficulties correctly, carefully analyze the causes of their learning difficulties, and consciously "favor poor students" so that students can repeat mathematics learning, thus stimulating their self-confidence in learning mathematics and creating conditions for them to experience the joy of learning success. Students with learning difficulties have received little recognition and encouragement in mathematics in the past. We should actively create conditions, fully encourage and affirm them, promote their interest in mathematics, make them succeed in mathematics learning, and make them feel that they can learn mathematics well. According to the actual situation of students, we should reduce and adjust some teaching requirements to meet the needs of students at a certain level, promote the adaptation of teaching and learning, and promote the unity of teaching and learning.
In teaching, the classroom teaching method of "low starting point, multi-induction, diligent practice and quick feedback" is implemented to help students with learning difficulties build up their confidence in learning mathematics and prepare for learning mathematics well. However, if students do not have a personal feeling and interest in learning mathematics well, this confidence will not last long, and it will lead to greater failure and inferiority. Therefore, after helping students build up their self-confidence in learning mathematics, it is more important to create conditions for students with learning difficulties to really learn and master the mathematics knowledge required by the syllabus, so that they feel that they have learned mathematics well. To achieve this, we must base ourselves on the classroom teaching reform and implement the classroom teaching method of "low starting point, multi-induction, diligent practice and quick feedback", with the focus on cultivating and developing students' learning ability.
Sixth, do a good job in extracurricular counseling.
At present, students' study habits, behavior habits and learning attitudes have declined to some extent. A considerable number of students lack the consciousness and initiative of learning, often fail to complete basic learning tasks on time, and some even feel tired of learning. In view of this situation, extracurricular counseling and psychological communication are particularly important. After class, students at different levels are given corresponding counseling to meet the needs of students at different levels. Let them realize the importance and necessity of learning, make them interested in learning, stimulate their thirst for knowledge and self-motivation through various channels, let them realize that learning is not a task, nor a painful thing, but full of fun, so as to consciously devote themselves to learning and make learning a part of self-awareness. On this basis, teach them to learn methods, improve their skills, and do a good job in checking and filling gaps.
Seven, strengthen learning, and constantly improve the overall quality of individuals.
Teachers should constantly update the teaching form, and the mathematics teaching under the new curriculum standard needs teachers to organize a lot of mathematics activities to let students experience the process of knowledge generation and development. Teachers should constantly update teaching languages and textbooks. Vivid materials can leave eternal memories in students' minds, while vivid language is a good way to stimulate students' thirst for knowledge. Students of different ages have their own way of thinking and habits. Teachers should choose appropriate materials and use appropriate language according to the characteristics of students in order to achieve the expected results. Teachers should constantly update teaching methods and master math skills. Mathematics teaching under the new curriculum standard can not meet the requirements only by traditional chalk and blackboard. There are many pictures and images that need multimedia display, and many processes of knowledge generation and development need computer demonstration. In teaching, we often encounter some phenomena, such as explaining some concepts and formulas in more languages, which is often the focus and difficulty of teaching. With the help of multimedia-assisted teaching, these phenomena can be activated, and they are particularly intuitive and vivid, from which students can feel the knowledge of mathematics without teachers. In order to provide students with rich knowledge and materials, teachers must master modern teaching methods.
Only by constantly strengthening learning, not sticking to the rules, paying attention to teaching accumulation and teaching practice, and constantly improving teachers' comprehensive quality can we meet the needs of teaching development.
