1 high school mathematics set problem solving method
Mathematics is one of the subjects in the college entrance examination, so we should study it seriously from the first day of junior high school. After entering high school, many students often can't adapt to mathematics learning, which in turn affects their enthusiasm for learning and even their grades plummet.
There are many reasons for this. But it is mainly caused by students' ignorance of the characteristics of high school mathematics teaching content and their own learning methods. Many students pin their hopes of improving their math scores on doing a lot of exercises.
I don't think this is appropriate. I think, "Don't judge heroes by how many questions they do." The important thing is not to do more questions, but to do them efficiently. The purpose of doing the problem is to check whether you have mastered the knowledge and methods well. If you don't master it correctly, or even have deviations, the result of doing so many questions is to consolidate your shortcomings. Therefore, we should do a certain amount of exercises on the basis of accurately mastering the basic knowledge and methods.
Secondly, we should master the correct learning methods. In order to train their ability to learn mathematics and change their learning methods, we must change the learning methods that are simply accepted, learn to learn to learn by accepting learning and inquiry learning, cooperative learning and experiential learning, and gradually learn the learning methods of "asking questions, exploring experiments, discussing, forming new knowledge and applying reflection" under the guidance of teachers. In this way, through the change of learning methods from single to diverse, our autonomy, exploration and cooperation in learning activities have been strengthened and we have become the masters of learning.
2 Time allocation
Overall time allocation of college entrance examination mathematics
When doing multiple-choice questions and fill-in-the-blank questions, the average answer time for each question is 3 minutes, and the easy questions strive for one minute to get the answer. 12 multiple-choice questions, 4 fill-in-the-blank questions, each with 5 points. Try to score these 80 points in 48 minutes. Because there is basically no time to go back and check, we should try to finish the test questions at once. When doing big questions, the average time to answer each question is about 10 minutes. Students with different foundations have different feelings about the difficulty of the test questions. Students with a solid foundation can attack the last few big questions if they answer the questions smoothly and have plenty of time. Students with average academic performance at ordinary times should ask as many questions as possible about the last few big questions and try to get a step score; Generally speaking, candidates with weak grades should focus on multiple-choice questions and fill-in-the-blank questions, and do a few big questions. You can choose to give up the questions that you can't answer at last.
Make full use of 5 minutes before the exam.
Many students or parents don't know that according to the requirements of large-scale exams, five minutes before the exam is the time to distribute papers, and candidates fill in the admission ticket. You are not allowed to do the questions for five minutes, but you can look at the questions. I found that many candidates began to read the first question after they got the test paper. My advice to you is that if you get this set of papers, these five minutes will be the key moment to formulate the whole strategy. You didn't see the topic before, but you were dreaming. When you see the question, you should use these five minutes to quickly work out the strategy for the whole exam.
Examine the questions before the exam.
After the exam begins, many students like to write hard; But remember: the exam must be careful and slow. Math problems often hide the key to solving problems in a sentence and a data. You can't read the words and data, or you can't find the key to solving the problem, or you read the wrong question. If you do it on the basis of misreading, you may feel relaxed, but you won't get any points on this question. Therefore, you must carefully examine the questions. Only when you understand the meaning of the question can you answer correctly. Problems that can be done don't waste time. What really wastes time is in the process of reviewing questions and finding ideas. As long as you find an idea, simply writing down those steps doesn't take time.
3 answering skills
When answering the math questions in the college entrance examination, everyone starts to answer the questions according to the order of the math papers, because when writing the papers, the teachers usually answer the questions from easy to difficult according to the difficulty of knowledge, which relieves the students' test pressure and makes them gradually enter the test state. However, when you come across a problem that you don't have any ideas or can't do at all, you should skip this problem for a while, don't waste too much time, answer the math problem that you are sure to score at the back first, and then solve the math problem in the rest of the time. Because the time for the math test in the college entrance examination is limited, the method of reasonable planning time is very practical in the college entrance examination.
Finally, when the whole college entrance examination paper is handed out, we must follow the arrangement of the invigilator and check the integrity of the paper. Don't save a minute or two. If there is any problem, report it to the teacher in time, because the integrity and consistency of thinking are very important in the math exam of the college entrance examination. If you find a problem halfway, it will not only affect the time, but also interrupt the coherent thinking of answering questions and waste time. The college entrance examination is a serious examination, so we should master some skills and methods of the college entrance examination.
Standardized answers: Judging from the common mistakes made by college entrance examination students in previous years, standardized answers are very important. Many subjects are graded step by step. Even if a question is not finished, you should write down what you know to do step by step. Recently, we should look at the detailed grading standards of the college entrance examination papers in the past three years, learn to find scoring points from the papers, and know how to accurately and firmly grasp the scores.
4 answer ideas
Thought refining method
Give birth to inspiration to solve problems. "Without problem-solving ideas, there is no problem-solving inspiration". But "problem-solving thinking" is both familiar and unfamiliar to many students. Familiarity is because the teacher talks every day, and strangeness refers to what it is to come uninvited. Students are advised to do more typical math problems under the guidance of teachers, so that they can master them quickly.
Good at typical problems.
Grasping the "28 rule" of key test center management says that 20% of important work produces 80% of the effect, and 80% of trivial work only produces 20% of the effect. The same phenomenon exists in mathematics learning: 20% of the topics (key topics, topics concentrated in test sites) contribute 80% to the test scores. Therefore, to improve math scores, we must give priority to those 20% questions. In view of the phenomenon that many students "have too many answers to the questions, they can't learn them thoroughly", we should use our brains scientifically, so that the typical questions in each chapter are fully prepared and they will be handy when solving problems.
Step by step in-depth error correction method
The "barrel theory" in the management of consolidating weak links says that the water quantity of a barrel is determined by the shortest board, not by the longest board. The same is true of learning mathematics, and the results of mathematics exams are often greatly affected by some weak links. Therefore, it is more important to consolidate a weak link than to do a hundred questions correctly.
The above are the relevant suggestions for solving problems in high school mathematics sets, and I hope they will help you.
