Review class is a class that helps students to sort out and deepen what they have learned, form a systematic cognitive structure, and make students improve systematically. By reviewing and sprinting, the knowledge learned in primary school for six years is sliced horizontally and arranged vertically, forming a knowledge network, which is densely distributed in students' minds. You can easily find the knowledge you need from this knowledge tree and apply it. Most of the mathematics in the second volume of the sixth grade of People's Education Press is comprehensive review, which has become the whole life of sixth grade teachers, parents and students. Teachers usually adopt the following methods: first, teachers take explanation as the main teaching form, which can not arouse students' initiative and enthusiasm in learning; Second, students often take memory as the main learning form in the review stage; Third, a large number of mechanical exercises are the main means and forms of knowledge consolidation. This review teaching mode makes teachers focus on consulting a large number of reference books and correcting test questions. Teachers are very tired every day. Faced with students' anxiety about the enrollment rate, they are afraid that they can't put all the knowledge into students' minds. The more the teacher combs the knowledge, the more he talks about everything, and the students are dizzy and often feel exhausted. Coupled with the pressure of entering a higher school and the mechanical repetition of a large number of non-targeted exercises, students are physically and mentally exhausted, slow to respond, and there are still many loopholes in the exam, so they cannot play their true level. In order to make the math review of the graduating class more effective, through my own practice, I think this form of review class is more effective. "Creating scenarios, leading to topics → group cooperation, reading → reporting and exchange, evaluation and reflection → summarizing and combing, building a knowledge tree → strengthening practice, expanding and extending".

First of all, create a scene and lead to a topic.

Learning without problems can only be "receptive learning", so mathematics teaching must first make students have problems, and review teaching is no exception. Teachers must create good "problem situations".

Second, group cooperation, reading and sorting

In the traditional review class, teachers often aim at "finding and filling the gaps" and present students with fragmented topics. Ushinski famously said, "Wisdom is just a well-organized knowledge system." Therefore, we should aim at the goal of "promoting the systematization of knowledge"

Third, report exchange, evaluation and reflection.

On the basis of cooperative arrangement, give students the opportunity to give full play to their talents, and let students explain their arrangement results and thinking process in their own language combined with some explicit actions. As long as they are given three or five minutes to show their findings in after-school research and provide them with a broader stage to show their talents, they can be inspired to explore tirelessly and cultivate some math lovers with unique thinking. Their explanations are more easily accepted by other students, and their positive learning style is more likely to drive and infect other students.

Fourth, summarize and comb, and build a knowledge tree.

"It's better to read it once, but it's better to do it once." It is always the teacher who combs the knowledge, and the students only do listening and foil. Use the students' sorting results to sort out the knowledge. Let students experience combing and constructing knowledge network by themselves, give them full space to show their individuality and independent thinking, let them all participate in the learning process, and cultivate and develop their emotions, attitudes and learning ability. For example, in the review of "simple operation", the teacher first lets the students sort out the definition and nature of simple operation themselves, and then carries out cooperative learning to carry out interactive activities between students and between teachers and students. The teacher instructed to sort out and summarize the methods. So, the students made their own knowledge tree diagrams, and many students drew tables. They organize knowledge as well as teachers. In the teacher's amazement and praise, the whole class's learning emotional climax was formed. I think we should pay attention to the following points in the explanation of math exercises:

1, close to the textbook. Most students will forget what they have said, so the review class should first focus on the textbook, review the concepts and important exercises in the textbook first, and help students recall the key points and difficulties that must be paid attention to in the new class and clarify the concepts.

2. Choose an example. Review class is a class that focuses on intensive lectures and more practice. If you want to have a good exercise class, you must choose good examples and exercises, especially when you are prone to mistakes. The selected cases must closely focus on the teaching purpose and be typical; We should proceed from reality and have a clear aim; Inference should be helpful and enlightening to students. In the review class, if the questions are explained in order, the same type of exercises are not explained in categories, which makes the knowledge accepted by students scattered. Therefore, in the teaching process, different types of topics should be classified and integrated, and in the process of explanation, such problems should be thoroughly explained so that students can fully understand them. Whenever there are questions you don't understand, you should practice more, increase your memory and achieve real understanding and mastery.

We should seriously consider the teaching methods. Many times, the review class adopts our traditional teaching mode: the teacher talks above and the students listen below. As a result, some students are not enthusiastic, feel relaxed in the review class, and the teaching effect is naturally not good. In fact, in teaching, I think we can change it, take students as the leading factor, and find out the problem through students explaining their wrong ideas. If students are allowed to express their wrong ideas, find out their common problems and then focus on explaining them, the teaching effect will be much better. Carefully study the selected examples before class to find out the best method or multiple solutions to a problem. In the explanation, we should be careful and appropriate, pay attention to inspiring students to think positively, let students gradually deepen and analyze layer by layer under the guidance of teachers, and let students listen systematically and learn actively. At the same time, we should deal with the relationship between speaking and practicing, and adopt different teaching methods according to different teaching contents, which can be based on speaking or practicing.

4. Carefully configure the exercises in and out of class. It is of course important to choose examples and explain them well, but students must use their own hands and brains to acquire knowledge and improve their ability. Therefore, for the review class, students are required to complete classroom exercises and do extracurricular exercises seriously. Teachers should carefully choose exercises in and out of class, and never engage in them hastily.

5, do a good job of phased testing. Stage test is the best way to test whether the teacher knows the deviation and whether the students really master it. Finally, according to the actual situation of the students in this class, the teaching method of teaching students in accordance with their aptitude and varying from person to person is adopted.

Five, strengthen practice, expand and extend.

The function of the review class should focus on "improving the ability to solve problems", including problems in mathematics and life. Therefore, in addition to certain quantitative requirements, practice should also highlight its comprehensiveness, flexibility and development. The forms should also be diverse, that is, practice with reason first, and then practice; Combining theory with practice means practicing while managing; The principle of giving priority to practice, that is, practice first and then management. Generally, the concept and geometry are reviewed by combing first and then practicing, mainly practicing calculation, and reviewing application problems, rules and laws while practicing. The types of exercises should also be focused. In the concept review class, knowledge points are easily confused with each other, and the choice of questions should be based on "analysis questions"; For example, in the calculation review class, we should pay attention to the accuracy of calculation and the flexibility of calculation methods, so it is better to correct the wrong questions and open the questions. Targeted practice can often get twice the result with half the effort. Without key points and flashy surface exercises, you can only get twice the result with half the effort.

In a word, the mathematics review class should fully embody the teaching concept of "student-oriented development", which can't be limited to how many sets of questions have been done and how many definitions have been recited. Instead, students should take the initiative to sort out what they have learned for six years and form a knowledge system. Pay attention to the differences between knowledge and recognize the essence of each part of knowledge. Only in this way can knowledge be applied freely. The essence of review class is to clearly form a knowledge tree in students' minds and let it take root and sprout. Only by keeping a clear head can students give full play to their knowledge level in the exam.
