How to create an efficient primary school mathematics classroom? First, students should be the main body.
Under the new curriculum concept, students are the main body of learning and the object of teachers' guidance, organization and cooperation. Teachers' teaching is not the ultimate goal, but the ultimate goal is to make students learn better. However, in actual teaching, in order to complete the teaching task and strive for the integrity of classroom teaching structure, teachers often ignore this center, unilaterally pursue integrity and abandon the foundation. If you are teaching? Trilateral relationship of triangle? At present, instead of guiding students to explore, operate and summarize the trilateral relationship of triangles, teachers use multimedia to display colorful triangle graphics to dazzle students, which is putting the cart before the horse. Students should be allowed to observe, communicate and place triangular figures. This will have a better effect. What is the essence of the new curriculum reform? All for the students, all for the students, all for the students? These three points fully reflect the importance of students. Therefore, the classroom should be student-centered and make the classroom a stage for students to grow up; A paradise for growth.
Second, prepare lessons effectively.
Preparing lessons is the foundation of a good class. A class lasts only 45 minutes. If you don't prepare enough lessons, the teacher will think about where to go like a cursory glance. Teachers do not preset classroom generation in advance, and the efficiency will be reduced because of the poor adjustment of teachers in the classroom. As a math teacher, effective lesson preparation should do the following:
1, lesson preparation standard
The new curriculum standard has made scientific and specific provisions on the teaching objectives of different classes. Before teaching, we should study hard, understand the specific teaching objectives of different classes, have moderate positioning difficulty, fully consider the unity of three-dimensional objectives, and make different teaching objectives for different students. It is necessary to clarify the position of this section or this chapter in the whole book or section, adhere to the foundation and break through the difficulties.
Step 2 prepare teaching materials
Before teaching mathematics, you should be familiar with all primary school mathematics textbooks from grade one to grade six, and make clear the position and role of what you have learned in the whole primary school stage. At the same time, teaching materials are also the main source for students to acquire knowledge. Making full use of teaching materials and implementing creative teaching are the keys to building a harmonious and efficient mathematics classroom.
3. Preparation method
The new curriculum standard clearly points out that we should give full play to students' autonomy in the classroom. In the classroom, every teaching link should have specific methods suitable for students to learn, so that students can know what to learn, how to learn, and finally what kind of goals to achieve, so that students can master and accumulate certain self-learning methods and improve their self-learning ability.
Step 4 prepare students
Understand students' personality, and master students' learning situation and acceptance. Only in this way can we flexibly design teaching methods, implement hierarchical homework, train top students, make up for poor students and effectively coach individual students.
Step 5 prepare questions
Solving problems is the focus of mathematics learning, and the design of teachers' problems in class is the key to efficient teaching. When preparing lessons, we must focus on preparing lessons in class, and avoid asking questions at will and in vain. The problem design should be scientific, purposeful and hierarchical. Questions that need to be answered collectively should be moderately difficult, so that students can solve them in one jump. The problem design of individual problems should be hierarchical and have a certain depth for the problems of top students; For students with poor foundation, we can start with simple questions to cultivate their enthusiasm and enhance their successful experience. After asking questions, give students some time to think. When preparing lessons, we should also pay attention to the cultivation of students' problem consciousness. Sometimes it is more important to ask a question than to solve it.
Third, presuppose vivid and specific teaching situations.
? Let students learn mathematics in vivid and concrete situations? It is one of the important ideas of the new curriculum standard of primary school mathematics. Vivid, interesting and intuitive mathematics teaching activities, such as telling stories, playing games, intuitive demonstrations and simulated performances, make full use of students' life experience and make teaching activities get twice the result with half the effort. Good situational lead-in is the beginning of a good class, which can make students focus on the content of classroom teaching quickly, stimulate students' strong interest in learning and thirst for knowledge, make students' learning state active, and make students learn knowledge in a relaxed and happy atmosphere. Like freshman year? About what? In the teaching process, I asked the students to divide the four students into a group by playing games, and then asked them to stretch out their right hands to shake hands, with the right hand touching the right ear, the right hand touching the left ear, the left hand touching the right ear and the left hand touching the left ear. In the process of each child participating in the game, experience the joy of the game and put mathematics knowledge? About what? Learn unconsciously in the game, and let students feel an effective problem-solving strategy.
Another example: teaching? Trilateral relationship of triangle? Once in class, I designed such a teaching scene. Miss Li found three pieces of wood and wanted to nail them into a tripod. Please think about it. Can the three pieces of wood found by Miss Li be nailed into a tripod? Can you help Miss Li? As soon as the students heard the teacher asking for help, their interest suddenly came and their enthusiasm was high. Some said they could, some said they didn't know, and some students said they would try. So, I let the students experience it by hand, and let them use three four-section wooden sticks prepared in advance to make various triangles in groups. Students in the activities of swinging sticks, while swinging and discussing, students have different findings:
1: I found that if the sum of two sides is less than the third side, I can't make a triangle because the head and tail can't be connected together.
Health 2: I found that the sum of two sides equals the third side.
Health 3: I think a triangle can only be spelled if the sum of two sides is greater than the third side.
In this case, it not only stimulates students' interest in learning, but also inspires every student? Do math? Passion. Every child's activities have experienced observation, experiment, guessing, verification and other activities, and have experienced a process of knowledge re-creation.
I will let the children show all the students the way, so that the students can see at a glance, which is very easy to master? Trilateral relationship of triangle? . Then use courseware to demonstrate, so that students can understand it more deeply? Triangular trilateral relationship? Understanding knowledge is an important prerequisite for building an efficient classroom.
Fourthly, optimize the teaching process and choose effective teaching means and methods.
1, clever use of multimedia
Using multimedia teaching, students can get a lot of teaching information in a short time, and improve their learning interest and learning efficiency. For example, when learning the second volume of the first grade, "Looking for Laws", we can use courseware to show students colorful images and regular pictures in life, which is conducive to students' understanding of regular objects. With the modernization of education and teaching methods, multimedia has also played a multiplier role in the breakthrough of some difficult problems.
2. Flexible teaching methods.
Students are naturally lively and active. At this time, their thinking is mainly intuitive thinking. Teachers in lower grades can introduce cartoons, fairy tales, stories, games, competitions and other forms that children like into the classroom. For example, when learning abdication subtraction within 20 years, students are not very interested in boring calculation, but the author effectively stimulates students' interest in learning by means of games and competitions. In teaching, we should use a variety of teaching methods flexibly to make teaching real? Live broadcast? Get up.
Fifth, cultivate students' independent thinking and cooperative communication ability.
The outline of basic education curriculum reform points out:? Change the current situation that the curriculum implementation places too much emphasis on learning, rote learning and mechanical training, advocate active participation, willingness to explore and diligence in learning, and cultivate students' ability to collect and process information, acquire new knowledge, analyze and solve problems, and communicate and cooperate? ,? Group cooperative learning? It is an effective way of education and teaching. It exchanges, synthesizes, improves and applies different knowledge. It allows children to actively participate in classroom learning, greatly improves students' academic performance and promotes students to form a good thinking quality of unity and mutual assistance. Can fully mobilize students' initiative, enthusiasm and creativity in learning; Can cultivate students' ability to express themselves actively; It can make students actively participate in mathematics learning activities, experience the generation process of mathematics knowledge and feel the fun of solving mathematics problems. In the process of implementation, students really become the masters of the classroom.
For example: in? How much less than a dozen? In our teaching, when students calculate 12-9=□, I let students study in groups and students actively participate. After discussion, different calculation ideas are obtained:
Health armor: because 9+3 gets 12,12-9 = 3;
Health B: Because 3+9 gets 12,12-9 = 3;
Sheng C: Because 10-9= 1 and 1+2=3, 12-9=3.
Look, children's thinking is so active that their ideas sometimes make our teachers feel bright. Not only the classroom teaching, but also our teachers should pay attention to design? Open? Training questions cultivate students' divergent thinking, divergent thinking, intuitive thinking and dialectical thinking, which are the basic components of innovative thinking and can fully cultivate students' autonomous learning ability.
In short, teachers should really implement efficient classes in the classroom, so that students can learn easily and teachers can teach easily, and truly realize the goal of students' all-round development. To achieve this goal, teachers need to constantly study and summarize, and Qi Xin should work together to train successors in the new era!
