How to improve the teaching quality of 1 primary school mathematics
Change the role of teachers
What role should teachers play in modern education? With the gradual transition from exam-oriented education to quality-oriented education, a set of traditional and lagging education and teaching models formed over the years due to the influence of exam-oriented education has obviously failed to meet the needs of educational development. Especially as a junior high school math teacher, I think the classroom teaching of primary mathematics should be innovative, and teachers must change the old ideas and behaviors that have been formed with knowledge as the core, and change the teaching goal that only pays attention to classroom knowledge and ignores the cultivation of ability, attitude and innovative spirit. Effectively change the past injection teaching methods; It truly embodies the diversification of teaching forms, allowing students to explore, discuss, practice, cooperate in learning, exchange experiences and help each other, making the teaching atmosphere harmonious, making students learn vividly and happily, truly returning the math classroom to students, and truly making students think more, see more, do more and speak more. Therefore, I think the teacher's role should be positioned as a guide in students' learning, and students should boldly let go to understand knowledge from perception, turn teachers' teaching into students' learning, and return to students' dominant position. Let them play in school and middle school to promote students' all-round development.
Pay attention to the cultivation of students' practical operation ability
Practical activities are one of the main ways for children's development and growth, and also the carrier for students to form practical ability. According to the age characteristics of junior students, in mathematics teaching, I think we should pay attention to cultivating students' thinking ability, active participation consciousness and innovative learning ability through practical operation, so that students can initially learn to use the knowledge and methods they have learned to solve some simple practical problems. In the teaching process, every student is provided with the opportunity to show and make intuitive materials, so that students can discover the rules, summarize the characteristics and master the methods by themselves in the hands-on operation, understand mathematics, learn to imagine and create in the experience, and get rid of boring mathematics, thus promoting students' interest in learning mathematics actively. In the lesson "Understanding Calculators", students prepared calculators. I let them calculate at will first, then let them talk about how they operate one by one, and guide the students to find and summarize themselves. In the "you say I do" session, one student says a formula, and other students are scrambling to figure it out, so there is no leisure to do small moves. The students in the whole class are focused, interested and active, and have achieved good teaching results.
Using multimedia teaching to enliven mathematics classroom
The new curriculum reform puts forward higher and newer requirements for the use of teaching methods. Fully introducing modern teaching tools such as computers into teaching will bring infinite vitality to the classroom. At the same time, the use of modern teaching methods in teaching is the need of implementing quality education and the needs of the times. Multimedia integrates sound, text, image and video, and has strong expressive force, which greatly makes up for the limitations of self-made teaching AIDS. When I use multimedia teaching, bright colors, lovely images, vivid movements and quick switching attract students, concentrate their attention, greatly improve students' interest in learning and improve the effect of classroom teaching.
2 to improve the efficiency of primary school mathematics classroom
Know the subject of the classroom
Teachers have tried many methods to improve the efficiency of mathematics classroom in the fourth grade of primary school, but most of them have failed. The main reason is that they don't really realize who is the subject of the classroom. Even if the method changes their ideas, the classroom efficiency has not changed at all. The reason why the rhythm of primary school classes depends on teachers is that primary school students have no ability to judge what they have learned well and what needs to be strengthened, so they must rely on teachers' judgment to make their classes more efficient. The teacher asked the students how to do more in teaching. When teaching new knowledge points, students may have a lot of doubts, but they are often used to keeping their mouths shut. The fourth-grade pupils think they have enough thinking ability to think about some problems, but they are not. Since the students don't say anything, the teacher should take the initiative to ask.
For example, ask students, do you know how to solve it? What methods should we use to solve this problem? If the students give corresponding responses, the teachers can understand that they should not have too much problems with such topics, so they don't have to waste too much time on it. If students don't attend class, there will be no response. Teachers should spend more time on this knowledge point and deduce it slowly. Finally, teachers should be more patient with students. In learning, it is inevitable that some students learn well and some students learn poorly. The fourth-grade students have the ability to distinguish. If teachers treat students with poor grades coldly again, they will be even less integrated into the classroom. In order to improve classroom efficiency, teachers should treat students with learning difficulties as the main body of the classroom, and change their attitudes towards mathematics by changing their views on teachers, which is of great help to improve classroom efficiency.
Dare and be good at changing teachers' roles.
For a long time, due to the deep-rooted influence of exam-oriented education, the education and teaching model has been unable to meet the needs of educational development. As a primary school teacher, to improve the quality of mathematics teaching, we should first dare to change the role of teachers, innovate in classroom teaching, and attach importance to the cultivation of students' ability, learning attitude and innovative thinking. This kind of spoon-feeding teaching method replaces the traditional teaching. Teachers simply speak and students listen passively. Through colorful classroom teaching mode. Mobilize students' learning enthusiasm, let students discuss and help each other in class teaching, and truly establish the concept that students are the core of class.
Specifically, to realize the transformation of teachers' roles, we should pay attention to the following aspects. First of all, we should change the concept of mathematics teaching. With the concept of new curriculum reform put forward, mathematics teachers in the new period should change the traditional spoon-feeding teaching mode. Teachers should play a guiding role, try to let students discuss and cooperate in groups in class, and evaluate and guide on this basis, and the teaching effect will definitely change significantly. Second, mathematics teachers should further strengthen their knowledge literacy and change from single-type teachers to comprehensive teachers. A math teacher can't just focus on math teaching. In fact, teachers' knowledge literacy should include professional knowledge literacy, cultural knowledge literacy and educational knowledge literacy. Under the background of new curriculum reform, mathematics teaching may involve many subjects and knowledge, which requires mathematics teachers to improve their knowledge structure to meet the teaching requirements of teachers under the background of new curriculum reform. Therefore, mathematics teachers should take the opportunity of continuing education to further broaden the access to cultural knowledge resources, improve their knowledge literacy, show their comprehensive teaching ability in classroom teaching, and guide students to grow rapidly. Third, we should change from the leader of the classroom to the guide, and be equal disseminators and friends of knowledge. Under the background of the new curriculum reform, teachers should dare to change their traditional status, step off the platform, go deep into students, discuss, communicate and cooperate with them. Really adhere to the "student-oriented", give students the initiative in class, and give full play to students' role as the main body of teaching. Through the transformation from teacher-led to guidance, a new harmonious teacher-student relationship of democracy and equality will be gradually established, so that students can learn knowledge in a pleasant and relaxed atmosphere. Fourth, we should shift from indoctrination to service.
3 How to improve primary school mathematics classroom teaching
Cultivate students' subjective consciousness and activate classroom teacher-student interaction
Teaching is essentially a process of interaction between teachers and students. In primary school mathematics teaching, teachers' teaching and students' learning should be perfectly combined, so that classroom efficiency can be guaranteed most reliably. For a long time, this problem has not been well solved. One of the most important reasons is that students lack subjective consciousness in the process of classroom teaching, but many teachers don't realize this, and blindly arrange the classroom teaching too tightly, which makes students in a passive state in the classroom. Over time, students will form a kind of thinking inertia. Therefore, in order to build an efficient classroom, teachers should first clarify students' dominant position in the classroom, cultivate students' subjective consciousness, and keep students' thinking active, so that teachers and students can form a good interaction, and teachers' teaching and students' learning can be perfectly combined.
Improve the interest of classroom teaching and stimulate students' interest in learning.
In primary school mathematics teaching, because students' learning purpose is not very clear at this stage, they also lack the enthusiasm and initiative of learning, and most of the motivation for learning mathematics comes from interest. Therefore, teachers should firmly grasp this psychological characteristic of students and pay attention to the improvement of classroom teaching interest, so as to promote students' interest in learning this subject. Teachers should also create a good classroom learning atmosphere for students, so that students can be in a relatively relaxed and happy state in the process of classroom learning, so that students' thinking activity will be higher and learning efficiency will be higher. When students' learning efficiency is effectively improved, the efficiency of the whole classroom teaching will naturally improve.
Delaying students' evaluation and developing students' thinking ability
Teaching should not only let students master the basic knowledge of the subject, but more importantly, let them participate in the process of knowledge formation. The principle of delayed evaluation should be used in teaching to enrich imagination and make free space. Advocate "everything you know, everything you can say, and give full play to students' initiative." "For example, in the practice of complex inverse proportion application problem, there is a problem that" a pile of coal actually burns only 2.4 tons per day, which is 0.6 tons less than the planned daily consumption. This pile of coal can burn for 96 days. How many days can it actually burn? "The wrong column of students is: (2.4-0.6)X=0.4×96. At this time, teachers can use the delay principle to guide students to correct themselves by asking questions. What is your equation based on? What does (2.4-0.6) mean? what do you think? How to understand the actual saving of 0.6 tons per day than planned? So (2.4-0.6) refers to the original planned daily coal consumption? How to make the original planned daily coal consumption? (2.4+0.6) Who is the correct multiplier? By thinking about the above problems, the difficulties that teachers should explain and analyze will be turned into the contents that students should explore themselves. We are exploring ways to learn thinking in middle school, cultivating good thinking quality of self-correction and improving students' thinking ability.
Dewey, an American educator, pointed out: "People who really think learn more from their own mistakes than from their own achievements. Only by combining mistakes with exploration can we breed truth. " In teaching, teachers can use wrong examples to enlarge them in time, or design corresponding multiple-choice questions and judgment questions, so that students can know their mistakes and why they are wrong in the exploration of right and wrong. Only by rational reflection on the "wrong case", distinguishing similarities and differences, and exploring the "root cause" can we prescribe the right medicine.
4 How to improve the quality of mathematics teaching
Starting from reality, let students feel their own value.
First of all, let students know that their words and deeds reflect their own values in all aspects. How happy it is to show the good things to everyone and get their approval! From now on, it won't be long before you do what I ask, and your progress will be great, which means your value will increase.
Establish a good relationship between teachers and students
Teachers' healthy emotions and positive emotions are prerequisites for creating a good classroom atmosphere. Because emotions and emotions are contagious. Therefore, from the moment the teacher walks into the classroom, all the attention should be focused on the students, and they should look around the students with warm and cordial eyes, say hello to them, announce "class", and put their emotions into every word they say. Teachers' high participation in the classroom will make students be subtly influenced and actively participate in learning, while students' active participation will make teachers constantly adjust their teaching behavior to adapt to the emotional state of students' active participation and create a good teaching atmosphere and the best teaching environment.
Form a good classmate relationship
Harmonious classmate relationship can make students gradually develop good qualities of self-esteem, self-love, self-confidence, self-improvement and sincerity in good communication. In classroom teaching, organize students to carry out cooperative learning to meet their psychological needs. Students express their opinions, exchange opinions and expand their thinking in group discussion, which not only improves their language expression ability, but also cultivates the spirit of cooperation. Helping and encouraging each other in cooperative learning greatly improves classroom efficiency.
Stimulate students' interest in learning with game teaching method.
In the classroom, teaching methods should be diverse and colorful. The organic combination of various teaching methods provides students with time and space for practice, independent exploration and cooperation. In teaching, I implement the classroom teaching method of "low starting point, more induction, diligent practice and quick feedback". Try to achieve "student-student interaction, teacher-student interaction" in classroom teaching. As the saying goes, "there is no fixed method in teaching, what is important is the proper method." As long as it can stimulate students' interest in learning and improve their enthusiasm for learning, any method is good.
