1 how to improve the quality of mathematics teaching in grade four
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 "The relationship between three sides of a triangle", the students all prepared three sticks. I asked them to put a triangle by themselves first, and then asked them to tell them one by one what kind of triangle they put. Why? This leads to the concept of triangle, which allows them to find and summarize by comparing the length of two sticks and another stick. In the "you say I'll do it" session, one student said a triangle, and other students scrambled to play, so there was no leisure to make 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. Mainly to improve students' interest in numbers and mathematics.
2 Mathematics teaching methods
Stimulate students' interest and emotion in learning.
In learning activities, students' interests, emotions and other psychological factors will have an important impact on their cognitive process. When students are interested in learning materials and have positive emotions, they will have strong yearning and desire to learn from their hearts, and then have positive learning motivation. An effective way to stimulate students' interest in learning is to let students see their progress and get praise from teachers. My creed is: to let students learn mathematics well, we must first make students like learning mathematics; In order to make students like learning mathematics, we should praise them by all means, so that each student can establish a good psychological quality and study habit of self-improvement, self-reliance and autonomy, and let students operate with their hands, eyes, mouth, brain and other organs, which will easily arouse students' interest. For example, after teaching the "Preliminary Understanding of Fractions", create a situation: put three white balls, four red balls and two flower balls in an assembled circle, let students observe and say how many white balls account for (3/9), and then add a flower ball to the circle, and how many white balls account for the total at this time (4/ 10). Students appreciate the relationship between part and whole and the relationship between change and development in this playful emotion.
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.
3 Mathematics teaching methods
First, establish an equal relationship between teachers and students
After several years of primary school study, students' mathematical thinking and thinking ability have changed greatly. Harmonious teacher-student relationship is the basis for the smooth progress of teaching activities. If the relationship between teachers and students cannot be established correctly, there is no way to achieve good teaching results. Therefore, teachers should gradually integrate with students, deeply understand their inner thoughts and help them build up their self-confidence in learning.
Second, physical model teaching
In order to improve the efficiency of students' attending classes, it is necessary to use physical model teaching method to attract students' attention, thus making mathematics teaching more interesting. The fourth grade of primary school studied angle measurement last semester, and students may not fully understand the concept of angle at first. Teachers use a triangle or hard paper strips that can be nailed together to stimulate students' learning enthusiasm through this physical model or hand-made learning tools. At the same time, it also increases the interest of teaching. Although the students in the fourth grade of primary school have begun to study in the senior grade, their imagination needs to be further improved. Therefore, through this physical model, abstract knowledge can be transformed into intuitive knowledge.
Third, add games to teaching.
In order to enliven the classroom teaching atmosphere, we can add teaching games to adjust the classroom atmosphere. Making the teaching content into games can improve students' interest and ability to master knowledge, let students experience the fun of learning mathematics knowledge in the competition, and pay more attention to mastering mathematics knowledge. Students at each stage have their own differences. For the students in the fourth grade of primary school, it is necessary to improve their thinking ability, take into account their nature and let them adapt to their own interests. Only in this way can students enjoy learning mathematics more. In order to achieve this teaching goal, teachers should constantly improve their interest in teaching.
4 Mathematics teaching methods
1. Thinking ability. Junior high school mathematics curriculum standard points out that developing thinking is the core of cultivating ability in mathematics teaching. The persistence of learning and thinking ability determines the depth and breadth of thinking and the development of innovative ability. Cultivating innovative thinking ability is necessary for the flexibility of analyzing and solving problems. "Mathematics is the gymnastics of thinking" shows the important role of mathematics in the development of thinking. Therefore, in the cultivation of students' ability, we should put the development of innovative thinking ability in the first place to lay a good foundation for their future development.
2. The ability of cooperative learning. Cooperative learning is the need of students' progress in the learning process, which is helpful to cultivate students' cooperative spirit and competitive consciousness and to teach students in accordance with their aptitude. For a problem, if a student thinks, his thinking is not open and agile. Several students cooperate, you have an idea and he has a method, then this problem can be easily overcome, thus enhancing students' confidence. When discussing a problem, in order not to lag behind others, some students often have a deep understanding of the problem, which is helpful to the development of thinking. In the process of cooperation, students not only learned knowledge, but also enhanced friendship and finally improved their comprehensive quality.
3. Self-study ability. Mr. Ye Shengtao said: "Teaching is for not teaching." When we are in class, we should teach students certain learning methods and teach them the ability of self-study. Without the guidance of teachers, students can still study effectively. This is the purpose of teaching. Self-study ability determines and influences the formation and development of other abilities. Therefore, we should put the cultivation of students' self-study ability in a key position, give students a certain amount of self-study time in class, and develop their self-study potential.
