I am a math teacher. The following is what I wrote to a netizen last year for your reference.

Poor math students are a large group. These students have a weak foundation, poor self-study ability and very passive learning. They are facing more and more distant difficulties and are in danger of losing confidence gradually. Whether the review in the future can be greatly improved and finally win the college entrance examination is now analyzed in detail and supported. The worse the foundation, the greater the room for improvement. This is from the perspective of the difficulty structure analysis of the college entrance examination proposition. In the score of 150 in the college entrance examination, the proportion of easy, medium and difficult is roughly divided into 5/3/2, which is increased from 40~50 to 80~ 100, and the total proportion is 1 10. In many years' experience of walking in the college entrance examination, poor students should improve at least 40 points with hard work, especially in liberal arts, which has a greater chance of winning. The key here is determination, perseverance and implementing a good review strategy. Dare to do it, stand up and say, have a clear goal, and then make great efforts correctly! Hard work pays off! L Throw away the questions and take back the initiative-school review is aimed at middle-class students, and the starting point of review may not be high, but the reality of the classroom is that teachers will spend most of their classroom time talking about college entrance examination questions, and exercise classes mostly deal with middle-class and high-level questions, which makes poor students feel at a loss, unfamiliar with the basic questions and unclear, and lose their enthusiasm and hope for struggle in repeated defeats and wars. The best solution is to throw away the difficult problems, chew the foundation with all one's strength, practice the use of basic formulas and theorems repeatedly, and temper the general methods repeatedly, so as to form a firm memory and skillful direct application of theorem formulas, ensure to win the low-scoring questions and strive to win the middle-scoring questions. This can stabilize the basic score, provide the possibility for further breakthrough in the second round of review, and thus regain the initiative of review. Otherwise, it just passively follows and can't really keep up, wasting a lot of time and letting go of the opportunity to improve performance. There needs to be a set of materials suitable for basic exercises. I think the classification and compilation of real college entrance examination questions (which must have answers) is the most appropriate. When others are gnawing at difficult problems, we just need to learn this material well, and don't envy others for doing difficult problems. As long as our plan is feasible, we will stick to it! This requires patience and strong will. L research questions, choose some modules in one round-after reviewing in class and doing the real questions of the college entrance examination, we must make clear the content and types of the middle and low-grade questions in the college entrance examination in order to break through one by one. This requires serious work and repeated practice until you can pass the exam safely; Then, to choose modules that are easy to write down, specifically (suggested) are: (1) function module (in the main line position), triangle (traditional middle and low-level questions) module, straight line and circle module, probability module; (2) Propositions-traditional low-level test sites such as set, linear programming, complex number, algorithm, binomial theorem, mean inequality and three views. ; (3) Derivative, sequence and basic part of conic curve (solid geometry proof can be put into the second special review). Such as the above modules, do what you can, and win all or most of them is the greatest victory. For intermediate level students, you can also refer to this strategy to review, because a round of review still focuses on more basic things, but the class often goes out of shape, as if both teachers and students have a soft spot for difficult problems, which are deep and inexplicably difficult to attract. Here, whether you can firmly believe and go all out to implement this strategy is the key to the success or failure of the college entrance examination! L Ensure the quality of problem solving and improve the effectiveness ——( 1) Improve the accuracy of operation: poor math scores, mostly in operation, lazy hands and sloppy hands are common diseases. We should start with operation, pay attention to the rationality of operation and optimize the algorithm; (2) Fill in the blanks with big questions, calculate carefully, do not skip steps, and seek stability and accuracy; (3) Answer the first question well: It is a pity that some students simply give up answering questions completely. His first question is often a low-level one, so we must not let it go. L Cherish time and overcome yourself-if the foundation is weak and the problem is slow, you should spend more time. Time is a problem, especially for liberal arts students. They have enough time to study mathematics this semester, and they may prefer liberal arts subjects next semester. We should also overcome our sense of inferiority, not be ashamed to ask questions, and dare to ask teachers and classmates for advice. This requires a strong belief in ourselves-asking questions is a shortcut. The trick to grasp the main line of function is to use images skillfully-on the main line of function, there are many knowledge blocks such as power, finger, pair, triangle, inequality, derivative, sequence, etc., and when learning the maximum value of function, it often intersects with solid geometry and analytic geometry. Learning function well is equivalent to winning more than half of high school mathematics. In review, we should learn to draw various function images, and then skillfully use images to solve problems, so as to improve our awareness and ability of using images to solve problems. Images have all algebraic connotations of functions. With images, knowledge becomes visual, and with problem-solving ideas, problem-solving becomes simple and interesting. Grasping the present is equal to grasping the future-this semester is the golden period for reviewing to turn the tide. Seeing that many students are still hesitating and don't want to change themselves, I think they don't believe they can change themselves. As a teacher, I am worried about these students. It is not too late to work hard from now on. If I wake up after the Spring Festival, it will always be too late. We must seize the present.
