First, pay attention to guide students to review methods and improve review efficiency: 1. Before instructing students to review their study plans, teachers should carefully study the new curriculum standard and Guidance Opinions on Primary School Mathematics Review, so as to make students clear the direction, content and topic form of graduation examination, clear the review content, guide students to allocate the review time reasonably, and determine the review progress according to each student's actual situation. Only in this way can students think clearly, overcome blindness and actively engage in review. First of all, we spend half our time guiding students to review the contents of textbooks, focusing on the key points, difficulties, test sites and doubts in reviewing textbooks. The method is a combination of teacher guidance and students' independent review. In the review, students pay attention to checking and filling gaps, and teachers pay attention to solving doubts and doubts. In the review, we should pay attention to the problems existing in students' comprehensive exercises, and check students' knowledge mastery and ability to use knowledge in time. And do timely feedback, fill in the gaps in time, and minimize the missing points. Then spend a quarter of the time reviewing in stages, and review the unit content related to the content item by item. For example: review of numbers, review of geometry knowledge and so on. Combine different review contents. Identify different review points and difficulties, sort them out, and strengthen the systematicness of review. This is conducive to the systematization of knowledge and the grasp of its internal relations, which is convenient for integration. Do combing-training-expanding, orderly development, and really improve the review effect. The last quarter of the time is spent on comprehensive review, various questions and so on. In each comprehensive review, the ability of middle school students presents a spiral state. 2. It is boring to guide students to review concepts, formulas, calculations and so on skillfully in mathematics learning. As the saying goes, "Practice makes perfect." A good review method is an important way to improve the review efficiency. Use all effective means to fully mobilize students' initiative, creative knowledge and skills in review. Teachers should do four things in guiding review: the first is to set the tone. Give a review "guide sheet" to let students review according to the "outline" and master basic knowledge and skills. The second is to give the law. Give specific guidance on review methods. Be good at grasping key organizations to review. The third is the tree target. Discuss the difficult problems in the review and examine the authenticity. The fourth is to set the sample. Give a positive answer to the result of the debate, clarify the vague understanding and establish a correct view. 3. Guiding students to explore skills and laws and improving ability test are the main aspects of modern mathematics test, such as practical ability and innovative ability. Therefore, in the review process, students should be instructed to do some calculation exercises and innovative exercises regularly. Know that students master the key conditions of solving problems and the mathematical relationship in application problems, and summarize the laws and methods; Guide students to remove obstacles; For some seemingly complicated questions, guide students to cut branches and leaves, find out the core part, understand the meaning of the question faster and more accurately, and thus effectively complete the required answers. In this process, remind students not to memorize, broaden their horizons, cultivate their practical ability and explore skills and rules. 2. Pay attention to the study of teaching methods, so that review can be time-saving and efficient. 1. Teachers should preview every class, whether it is the review of basic knowledge or the review of key points, difficulties and points; Teachers should carefully analyze and prepare what they teach, whether it is special training or thesis evaluation. Teachers should carefully study textbooks and new curriculum standards after class, grasp the contents of textbooks, be good at refining and summarizing the knowledge points and training points of textbooks, and grasp the breadth and depth of quasi-knowledge. In the review process, we should pay attention to the use of teaching materials, and never abandon the teaching materials, engage in so-called "standardized training", blindly pursue the improvement of students' ability and despise the review of basic knowledge. 2. Accurately handle the relationship between centralized teaching and centralized teaching. "Centralized teaching is to strengthen teaching. It concentrates on thinking, time, all means and methods, creates environment and conditions, breaks through difficulties and drives comprehensiveness. " According to this principle, I think we should get rid of the shackles of the original knowledge system, break the original knowledge structure, readjust and edit the knowledge system, and rearrange and reassemble those basic knowledge. Through a series of bilateral activities such as pre-concentration, random concentration and comprehensive concentration, as well as inspiration, guidance, discussion, induction and synthesis, the knowledge points, hot spots and key points are concretized. This not only lays a solid foundation, highlights the key points, but also gives students new feelings. Intensive teaching refers to actively guiding students to learn independently, especially explaining puzzling or wrong problems in previous independent review activities and discussions, with the aim of eliminating students' learning obstacles, guiding learning methods and cultivating correct learning methods. In the review, select some appropriate, innovative examples that best reflect the essential characteristics of the review content, stimulate students' thinking inspiration, and arouse students' thinking loudly, so as to review the past and learn new things. When choosing examples, we should be "three natures". One is accuracy; Meet the requirements of the new curriculum standards and teaching materials, and beware of being too deep or too biased to increase students' heavy academic burden; The second is demonstration: it embodies important knowledge points and has the role of "example"; The third is comprehensiveness: it reflects the horizontal connection of various knowledge and cultivates students' comprehensive problem-solving ability. Generally speaking, when reviewing, we should select the knowledge that students usually miss, the knowledge that students easily confuse, and the knowledge that is critical and regular. 3. Carefully arrange exercises. We should take this as a key point. I think carefully arranging exercises is a good way to implement teaching judgment and feedback. It is effective to arrange proper exercise homework every day, find problems from the homework, guide students to discuss collectively, and use their spare time to correct them individually. "Teaching students in accordance with their aptitude" has been well implemented, with simple operation and obvious effect. Flexible training in review can achieve the purpose of consolidating knowledge, understanding laws, strengthening memory and using knowledge flexibly. First of all, live on the content of training. We should choose exercises with novel content, hidden rules and flexible thinking to create new thinking artistic conception. Second, live at the training level. Adopt flexible methods such as consolidation training, imitation training, variant training and comprehensive training. Third, live in the form of training. Strengthen the training of "one subject is changeable". Cover knowledge points and network knowledge lines as much as possible, expand knowledge and enhance adaptability. Strengthen the training of "multiple solutions to one problem" and find many kinds.
