First, study the examination outline and clarify the examination contents and requirements. In short, the examination syllabus is the specific provisions and explanations of what to take, how difficult it is and how to take it. Vocational schools pointed out to the outline of the college entrance examination for mathematics: "In the future, we should first learn basic knowledge, master basic skills, basic ideas and methods, as well as basic computing ability, spatial imagination ability, combination of numbers and shapes, thinking ability and simple practical application ability. On this basis, pay attention to the vertical connection of each part of knowledge in their respective development process and the horizontal connection of each part of knowledge intersection, sort out the context, grasp the backbone of knowledge and build it. Looking at the corresponding math test papers in our district in recent years, the overall difficulty and requirements are not beyond the outline. Therefore, we should pay more attention to the horizontal and vertical analysis of the examination syllabus, and find that the content changes every year, as do the types and proportions of the examination papers. If you review according to the outline, you can grasp the key points and avoid detours. Only in this way can we do less useless work and get twice the result with half the effort. Second, pay attention to the classification of knowledge and the accumulation of problems in review. Classified review is to review some questions in one place according to their characteristics. Concept is the most commonly used teaching method in classified review. The purpose is to use classification to help students relate and distinguish similar concepts, so that students can clearly understand the extension of concepts and deepen their understanding of the connotation of concepts, so as to flexibly use the concepts they have learned to solve practical problems. The process of using concepts is also a process of deepening the understanding of concepts, which can make students understand the meaning of concepts more deeply. 20 12 The mathematics test questions of the college entrance examination in higher vocational colleges adhere to the idea of ability-based, pay equal attention to knowledge and ability, return to the teaching materials, grasp the types of questions, pay attention to the classification of knowledge and the accumulation of questions, and emphasize "improving students' operation speed, paying attention to general methods and diluting special skills". Some knowledge points don't seem to have appeared in textbooks, but they are paper tigers, which can be broken with one poke. This requires candidates to pay more attention to the accumulation of these new types of questions and the methods of doing them in the usual drills, and strive to master them. They will become "magic weapons" to win in the examination room, such as finding specific coefficients in the equation, finding some algebraic values including the roots of the equation, and determining the coefficients of the equation from the roots of the equation. , in order to compile all kinds of questions. These questions examine the basic methods of mathematics teaching in vocational high schools, and also reflect the requirements of learning knowledge, mastery and assessment content stipulated in the examination syllabus. Therefore, only by thoroughly understanding the textbooks, carefully understanding and firmly grasping the concepts, theorems and formulas in the textbooks can we systematically master the basic theories and methods of mathematics, and correctly discover, analyze and solve problems. Third, pay attention to basic knowledge and master basic math skills. Most vocational high school students have poor math foundation. We should realize that mastering basic mathematics knowledge and skills is the premise and foundation of learning mathematics well, and it is the fundamental way to improve the mathematics score in the college entrance examination. No matter how the form of mathematics examination changes, in any case, we should clearly recognize our own gaps and shortcomings, lay a solid and serious foundation, master the basic skills of mathematics seriously, strengthen the management of mathematics teaching at ordinary times, master the teaching situation of mathematics in the whole school, and create a strong campus mathematics atmosphere, which is the most critical factor for mathematics review in the college entrance examination of vocational high schools. 1. Pay close attention to the examination of questions, highlight key points and strengthen training. Mathematics is a subject that uses formal symbolic language to reflect concepts such as quantity, structure, change and spatial model. Its symbol usually represents a broad concept, not a living space familiar to students, and its determination sets goals and standards for symbols. Therefore, only by understanding and mastering the basic knowledge and skills of mathematics can students improve their understanding ability of mathematical language. It is very important to explore the breakthrough of solving problems through the automatic analysis of the information in the mathematics of college entrance examination in vocational colleges, so as to determine the ideas, schemes and ways of solving problems. 2. Strengthen efforts to cultivate students' computing ability and the ability to analyze and solve problems. Judging from the mathematics examination papers of vocational college entrance examination in vocational schools in recent years, although the examination questions are basically the same and the difficulty is roughly the same, the increasing amount of calculation makes the requirements for calculation higher and higher, which causes many students to have great obstacles in solving problems. It seems that only with a lot of training at ordinary times can we cope with it easily in the college entrance examination. The strength of operation ability is mainly manifested in the correctness and speed of operation. After obtaining the breakthrough to solve the problem, under the guidance of basic concepts, main formulas and operation rules, the whole process of facts provided by words is explained by deductive reasoning, and a reasonable and simple operation mode is sought and designed to improve the rationality and simplicity of operation. 3. Improve students' ability to combine numbers and shapes, which brings great convenience to solving problems. In mathematics teaching, the idea of combining numbers with shapes to help numbers has the advantage of presenting problems intuitively. The thinking method of combining numbers and shapes is one of the important thinking methods to learn mathematics well in middle school, and its corresponding abilities include the ability to read pictures, the ability to imagine and think in space, and the ability to construct pictures. The ability to read pictures is the most basic and important ability to learn mathematics. Being able to read and use drawings skillfully and accurately is conducive to the lifelong development of mathematics learning. In the math review of college entrance examination in vocational high schools, it is very important to train, improve and demonstrate basic skills, and cultivate students' observation and creative activities, because this is the main direction of math review in vocational high schools.
