Special-grade teacher: What should we pay attention to in the math college entrance examination?
1. Grasp the rules and prepare for the exam accurately.

1. Peace and stability, justice and fairness: In recent years, from the perspective of difficulty and average score, there have been changes in stability and innovation in peace. The examination questions are simple and generous, emphasizing essence over appearance. The proposition adheres to the style of "originality first, adaptation second", and the knowledge points do not exceed the outline. The original questions can be set around the scenes that candidates are familiar with, and the adaptation questions come from textbooks, giving students a sense of deja vu.

2. Highlight the backbone and implement the four basics: the college entrance examination is not only a selective examination, but also a touchstone for testing candidates' staged academic performance. The key questions in the test paper, such as 1 1- 14 and 17-20, are basically based on the main contents of high school mathematics (such as functions, series, analytic geometry, solid geometry, triangles, vectors, etc.). ). The arrangement of test questions follows the psychological laws of the test and conforms to the test habits of candidates. Low starting point, wide entrance, from easy to difficult. The examination paper focuses on the examination of basic knowledge, basic skills, basic ideas and basic activity experience. This kind of examination is conducive to enhancing students' confidence in solving problems and ensuring that candidates of all ability levels can learn something and achieve certain results.

3. Pay attention to literacy and moderate innovation: "It is easy to get started, but difficult to go deep", which is reflected in the mathematics papers marked over the years. Jiangsu college entrance examination mathematics problems pay attention to the combination of foundation, comprehensiveness, application and innovation, and pay attention to the diversity of solutions and the difference of efficiency of different solutions. In the setting of difficult problems, the difficulty of each event is progressive and spiraling. This proposition not only encourages students to explore bravely, but also effectively distinguishes students' thinking level and mathematical literacy, so that candidates with excellent comprehensive ability stand out.

Second, reasonable planning and efficient answering.

1. Planning preset goal: The full score of the first volume of the college entrance examination mathematics volume is 160, but the actual "psychological preset full score" of different candidates depends on their own learning foundation. The "psychological preset full score" should be the sum of the scores of those questions that have the ability and the opportunity to do it right, after discarding those questions that have no chance to score. Candidates should carefully count the small-item scores of previous important simulation exams, check their mastery of various knowledge points, and preset scoring targets for different knowledge points, different types of questions and different positions, so as to plan a "psychological preset perfect score" suitable for them. Reasonable orientation and proper presupposition can effectively ensure that students at different levels can build up their confidence, tap their potential and play their due level.

2. Planning the pace of answering questions: Each student's preset goals are different, and the total number of questions to be completed during the exam is also different. Therefore, each student's answering rhythm should have individual characteristics, and can't blindly follow the trend. Every student should form his own stable answering rhythm in the final review stage. How long does it take to fill in the blanks according to your own learning foundation? How long will it take to solve the triangle and vertical problems? What is the scoring goal of analyzing geometry and application problems, and how much time does it take to allocate? How many questions do you need to ask for the final series and function synthesis questions? How much time is reasonable to allocate to overcome them? These questions must be arranged as a whole, so as to determine the rhythm of answering questions that suits you. The planning of answering rhythm must be based on ensuring the correct answering rate.

3. Planning the answer path: Answering questions requires wisdom, which is reflected in the choice of methods and the reasonable planning of the answer path. For example, when answering analytic geometry questions, should we set a point or a straight line? This depends on the specific test questions. What is the answer path under the premise of setting a point? Where is the node with the most complicated operation? Are you familiar with this operation? Then you set a straight line? Simply comparing and planning different schemes is bound to get twice the result with half the effort. For another example, when answering application questions, whether to set angle parameters, numerical parameters or point parameters in modeling needs to think about the answer paths behind different modeling schemes and compare them before operating. The exam should not be unplanned and blindly solved, otherwise it will be time-consuming and laborious, and the loss will outweigh the gain.

Third, pay attention to the specification and return the particles to the warehouse.

1. Basic answer specification for fill-in-the-blank questions: The answers to fill-in-the-blank questions must be answered according to the requirements of the questions. If the object is a set, the answer must be presented in the form of a set; If the domain of function value is required, the result should be written in the form of set or interval. If the standard equation of a circle is found, it cannot be written as a general equation; If the value is a fraction or a fraction, it should be reduced to the simplest form; The writing of fill-in-the-blank questions should be clear and standardized, not sloppy and vague, and should be easy for the marking teacher to judge and identify.

2. Specification for answering simple questions: the answering process of trigonometric function questions should be complete, and the original formula, deformation process, data substitution and result presentation should be interlocking; The reasoning process should be rigorous and standardized, the choice of symbols should be clear, and it should not be simple and casual by feeling; When determining the value of an angle, we must combine the range of the angle to make an accurate conclusion; When answering solid geometry questions, every conclusion should be well-founded and not vague; The reasoning conditions of each logical segment should be complete and indispensable; Before and after the logical segments should be closely linked, and irrelevant information should not be mixed; The process should be clearly written, and the important conclusion cannot be a clerical error.

3. Mid-range problem-solving norms: The application of the problem life system depends on the actual situation, and there should be necessary written explanations when answering questions. Pay attention to the unity of the unit when answering, check whether it conforms to the actual situation, and answer according to the actual questions after answering. When solving analytic geometry problems, special circumstances should be explained separately. The deformation process of the operation should be complete and detailed, and no false certificate can appear.

4. Standardization of complex comprehensive questions: The standardization of complex comprehensive questions is manifested in the rigor of thinking and the order of reasoning. Function synthesis problems should be carefully combined with numbers and shapes, and conclusions should be drawn according to strict logical reasoning, instead of relying solely on graphic intuition. When verifying the arithmetic geometric progression problem, we should strictly follow the definition. When using some special conclusions to help solve problems, we need to prove them as lemmas.
