: Grading skills for senior high school entrance examination:
1, we should take the mastery of basic concepts as the breakthrough of skills.
In fact, the so-called problem-solving skills in the test questions are not inscrutable things. They come from the most basic knowledge and concepts, and mastering them to a certain extent is an epiphany. Look for differences-because you have done many similar exercises, it is easy to make mistakes in judging similar questions, which is very dangerous
2, master the commonly used formula, understand its ins and outs.
This is very helpful for memorizing common formulas. In addition, it is necessary to further understand the derivation process and explore some possible changes in the derivation process. This is better than doing a lot of exercises, and it can make you better master the application of formulas, which often has unexpected effects.
3. We should grasp the trend of the senior high school entrance examination and practice the problem-solving norms diligently.
Many students think that as long as they have answered the questions, they can get full marks. In fact, due to the deepening of the new curriculum reform, the senior high school entrance examination pays more and more attention to the standardization and integrity of the problem-solving process. As long as there is a process to solve the problem, the process is much more important than the final answer. Therefore, it is necessary to standardize the writing process and avoid the situation of "meeting but not being correct" and "being correct but not complete".
4. Master mathematical ideas and summarize problem-solving methods.
The mathematical thinking methods that often appear in the senior high school entrance examination are classified discussion method, area method, special value method, number-shape combination method and so on. We use the thought of transformation, equation, function and transformation to solve some comprehensive problems, and memorize each method in our minds with a corresponding typical test question.
And purposefully break down the relatively comprehensive topic into several simple small topics, so as to draw inferences from others, simplify the complex and break through step by step; In the cooperative study with classmates, we should combine relatively simple questions into more valuable comprehensive questions.
The biggest feature of the senior high school entrance examination is shallow, wide, new and lively. Therefore, we should avoid complicated, difficult, biased and strange problems in review, otherwise it will waste time on the one hand and increase psychological burden on the other.
