However, the standard to measure an efficient classroom is not to enrich the teaching content as much as possible, nor to excavate the teaching difficulty as much as possible, but to determine the learning content reasonably according to the students' learning situation, choose teaching methods appropriately, use teaching strategies scientifically, fully highlight the students' dominant position, give full play to the leading role of teachers, and change the traditional "I want to learn" into the new "I want to learn" and the traditional indoctrination teaching into "intensive speaking and more practice".
So, how to create an efficient primary school mathematics classroom? Prepare lessons carefully and design classroom presupposition comprehensively and thoughtfully. Many young teachers are reluctant to engage in primary school mathematics education: I have experienced such a long learning experience and accumulated so much mathematics professional knowledge, but I want to engage in primary school mathematics education, with simple knowledge points and poor learning ability of students, which is simply overqualified. This mentality of teachers is directly reflected in their contempt for classroom teaching, and they think that knowledge points can be taught to students in an orderly way without preparing lessons. This wrong view is the biggest obstacle for teachers to move towards efficient classroom. Although the knowledge of primary school mathematics is relatively simple, how to establish scientific learning objectives according to the learning situation, what kind of classroom teaching mode and teaching strategy to adopt, optimize classroom teaching to the greatest extent, and mobilize students' active participation is the goal worthy of every teacher's lifelong pursuit.
Teachers should carefully prepare lessons, take the requirements of curriculum standards as the basis, take students' learning situation as the guide, carefully study teaching materials and scientifically integrate knowledge points. We should not only skillfully solve typical examples, but also try different solutions. According to students' level and thinking habits, we should think about which methods will be used to solve them. Can you guide students to think more ways? Teachers' classroom presupposition is also comprehensive and flexible, and cannot be decided by their own subjective judgment or previous teaching experience. They should have a certain foresight, predict what may happen in class that is different or even opposite to their own preset, and book corresponding countermeasures. To prevent unexpected situations in the classroom, teachers can't cope, which leads to the failure of classroom teaching procedures and affects classroom teaching efficiency. Therefore, comprehensive and meticulous pre-class presupposition is the basic condition to ensure the smooth progress of classroom teaching and create an efficient classroom.
Fully preview, so that students can know fairly well in the learning process. Teachers should cultivate students' habit of previewing before class, especially after the third grade, students have a certain degree of learning autonomy, and the learning content gradually becomes complicated. Preview can not only make students welcome the content of classroom learning, but also promote students to quickly enter the nearest development zone, roughly determine the important and difficult points of learning before learning, especially pay attention to the knowledge points that they don't understand or understand thoroughly in preview. Of course, the preview mentioned here is not a general browsing of textbooks in the traditional sense, but a preview topic designed by teachers in advance to guide students to think about some basic mathematics knowledge by reading textbooks. For example, before learning measurement, guide students to read textbooks, and then solve a series of preview questions: (1) Please measure the length and width of your living room with the help of your parents and record it. Observe the unit of length on the ruler. Which unit do you think should be used? Measure the length and width of your coffee table and record it. Thinking: Is the length unit used the same as that of the living room? If you are not sure, you can ask your parents. Don't forget to ask a few more why. )
(3) Measure the length, width and thickness of the math textbook you use and record it. How to choose the length unit is very important. I think you already know how to ask for help ) (4) Measure the length, width and thickness of the rubber you use and record it. What unit should I use for such a small thing? The teacher doesn't know either. Can you help the teacher solve this problem? The design of preview questions should be operable and enlightening, which can stimulate students' interest in learning and let students participate in preview happily. Even if students can't solve this problem, they can also attract students' attention to this problem and make full preparations for classroom learning. After students are fully prepared, their enthusiasm for participating in classroom learning will be higher, their thinking depth will be reasonably increased, their cooperative exploration will be more adequate, their goal breakthrough will be smoother, and their classroom teaching efficiency will be improved accordingly.
Timely adjustment to ensure the smooth and appropriate classroom teaching process: the new curriculum concept advocates autonomous learning, emphasizes giving full play to students' main role and encourages students to cooperate and explore, but it does not exclude teachers' guidance, cooperation and participation. On the contrary, the new curriculum concept further strengthens teachers' classroom regulation and puts forward higher requirements for teachers' classroom regulation and control skills. Teachers are required to observe students' learning situation at any time and adjust classroom teaching in time according to their own classroom presupposition. In teaching, if it is found that the teaching presupposition is too simple and still stays at the development level that students have reached, it is necessary to quickly lead the learning activities to the nearest development area of students by adding questions; If it is found that the teaching presupposition is too high and the difficulty of the question exceeds the students' recent development zone, teachers should reduce the learning difficulty by changing the question conditions to ensure the effectiveness of students' learning. In addition, teachers should also pay attention to observing students' cooperative inquiry activities, especially the student-student cooperation link.
Pupils are young, even if the teacher shows their learning goals, students may not understand their true meaning, and they don't know how to study and think around the goals, so it is easy to cause.
