Put the knowledge that is usually taught relatively independently into a string through sorting out reflection and practice, so as to deepen students' understanding and exchange of knowledge. The total review of primary school mathematics overemphasizes the amount of practice, which leads to students' fear and boredom of mathematics. Accordingly, the following countermeasures can be taken.
1. As the final review is a process of relearning the knowledge learned this semester, the review has a wide range, a large quantity, tight time and rich content. In order to make the review closer to reality and achieve better review effect in less time, the following review suggestions are put forward:
1, make a feasible review plan, and seriously implement the plan. In order to make the review targeted, purposeful and feasible, and find out the key points and difficulties, the new curriculum standard is the basis of the review, and the textbook is the blueprint of the review. When reviewing, we should find out the difficulties, doubts and the reasons why all knowledge points are easy to make mistakes, so that the review can be targeted and get twice the result with half the effort. 2. Sort out and strengthen the systematicness of review. The important feature of review is that under the guidance of system principle, the knowledge learned is systematically sorted out to form a relatively complete knowledge system, which is conducive to the systematization of knowledge and the grasp of its internal relations, and is convenient for integration. At the same time, pay attention to stimulate students to actively participate in learning activities, so that they can find problems, ask questions, think, discuss and analyze, and finally draw conclusions, and can use them flexibly to achieve carding-training-expansion and orderly development, and really improve the review effect. ?
3. Distinguish and compare, distinguish and clarify confused concepts. For confusing concepts, we should compare the meanings first, and then analyze the confusing concepts, so as to fully grasp the essence of the concepts and avoid the interference of different concepts. In addition, it is necessary to compare the confusing methods and clarify the solutions. ?
4. Multiple solutions to one question and multiple solutions to one question improve the flexibility of solving problems. Some problems can be analyzed from different angles and different solutions can be obtained. Multiple solutions to a problem can cultivate the ability to analyze problems, solve problems flexibly, have different solutions, different formulas and the same results, and get the same results through different routes, at the same time, inspire other students and broaden their solutions. Some application problems have different forms, but the method of solving them is the same. Therefore, when reviewing, we should think from different angles and classify all kinds of problems, so as to integrate what we have learned and improve the flexibility of solving problems. ?
5. Be targeted, explore and innovate. Mechanical repetition, talking about everything and practicing everything, is the taboo of review. Review must be purposeful and focused, and summarize and summarize the knowledge learned. Exercise should be open and innovative, so that thinking can be fully developed. We should correctly evaluate ourselves, consciously fill in the gaps and check the leaks, face complex and changeable topics, carefully examine the topics, find out the relationship between knowledge structure and knowledge laws, explore hidden conditions, think more and discover more, and get our own experience.
6. Educate students to form the habit of inspection. If we can pay attention to the importance of inspection when reviewing, the effect will be twice as effective.
Second, in the primary school mathematics review teaching, we should actively seek a variety of effective review methods, stimulate students' interest with vivid methods, and lay a good foundation for students' lifelong learning. Now I will talk about some review methods according to my teaching practice.
1, a game to arouse students' enthusiasm for learning?
I once read a sentence that thought is not a container that needs to be filled, but a torch that needs to be lit. It is necessary to put an end to the simple review of "fried leftovers" in the review class, create a variety of different scenarios, tell new ideas, stimulate students' enthusiasm and vitality for review, let them take the initiative to participate in activities, and enhance the internal drive of students' independent learning. ?
For example, when teaching to solve the review content of application problems by proportional method, I designed this class as an "obstacle-crossing" exercise in a smart room: every time students cross an obstacle, they can put a five-pointed star on their desks, and by the end of class, the students who get more can be named the "king of obstacle-crossing" of this class. The whole class consists of four links: the first level is called "step by step", which aims to clarify concepts and relationships. At this level, I have designed some related topics, so that students can think independently first and let their deskmates communicate with each other. The second level is called "Pass", which aims to improve students' speed and accuracy. In this paper, from easy to difficult, a certain gradient topic is designed. The third level is called "Eight Immortals Crossing the Sea", which aims to cultivate flexibility in solving problems. The exercises at this level are mainly to design some comprehensive and systematic problems, which need unique methods to solve. The fourth level is called "wisdom platter", which aims to improve students' cooperative learning and practical application ability, mainly some comprehensive and practical topics. Practice has proved that this method of turning boring review into interesting games can effectively mobilize students' initiative to participate in review. ?
2. Flexible use of learning tools to experience the process of seeking knowledge?
Bruner said: Exploration is the lifeline of mathematics. In children's spiritual world, they are more willing to be discoverers and explorers. Therefore, in the review, we should provide students with as many hands-on opportunities as possible, and use flexible learning tools to let students gain a lot of perceptual knowledge and experience the value of exploration.
3. Choose your own homework and establish a sense of theme?
An educator once said: The acquisition of knowledge should be a positive process. The same should be true for students to finish their homework. If you just turn homework into one-way giving and ordering, it will inevitably make students lose their appetite and get bored. This kind of homework virtually deprives students of their right to choose, inhibits their initiative to explore and acquire knowledge, and stifles the development of students' personality and creativity. Therefore, the principle of teaching students in accordance with their aptitude should be followed when designing homework. ?
4, inventory information, looking for a mirror to review?
Students' mathematical analysis is a mirror of students' review and teachers' teaching. Through statistical information, we can find students' learning quality and learning trend, as well as our own problems in teaching. The contents include: (1), summarizing the main points of knowledge; (2) analyze what knowledge is well learned and what knowledge is not well learned, and what are the reasons; (3) Summing up learning experience, methods and lessons; (4) Students give advice to teachers. ?
5, clever use of exercises, by analogy?
At the end of this semester, the further education school issued some corresponding review outlines. In the process of using, we should pay attention to the exercises that are easy to make mistakes and confusion, compare some similar exercises, or extend the exercises with similar quantitative relations for comparison and classification, so that students can master the problem-solving methods and improve their ability to solve practical problems. Such as; Comparison between prime numbers and odd numbers; Prime number and prime factor; Ratio and proportion, etc. The analysis of confusing concepts can help students fully grasp the essence of concepts and avoid the interference of different concepts. The confusing methods should also be compared, and the methods of solving problems should be clarified, such as comparison and simplification. ?
In the final review of primary school mathematics, teachers should teach students in accordance with their aptitude, give full play to their leading role, guide students reasonably and avoid the occurrence of "plateau phenomenon", which will play a good role in teaching. Only the method that suits your own reality is the best method. As long as we devote ourselves to research in teaching, there will be many new review methods to improve our education and teaching level.
