Analysis of Jiangsu's mathematics test paper can get the following points:
1, Jiangsu's math test paper is fluent and moderate, which is conducive to the normal play of candidates. The design of this test paper fully considers the answering psychology of candidates, and strives to make candidates have a peaceful mind when answering questions. Like the math test papers in recent years, the initial fill-in-the-blank questions designed a certain number of short answer questions, so that students can get basic marks. The transition from easy to difficult is also natural, which is beneficial for students to enter the state and play stably. For some questions that candidates may be afraid of, such as application questions and the following solutions (17, 18,19,20), students can get some inspiration when solving the previous questions, and then find a breakthrough to solve complex problems. 2. Jiangsu's mathematics test paper is scientific and standardized, close to the teaching practice. The examination paper is based on the teaching materials and strictly abides by the "examination instructions". 1~ 1 1, 15~ 18 and many other questions can be found in the textbook. Although some problems are original, the ideas and methods to solve them are universal in textbooks and daily teaching. The test paper comprehensively examines the basic content of high school, covering almost all C-level test sites and most B-level and A-level test sites in the test description. Aiming at the main contents of high school mathematics, such as function, sequence, analytic geometry, etc. This is very consistent with the daily teaching of high school mathematics. It embodies the consistency of curriculum, teaching and evaluation.
3. The inheritance of Jiangsu mathematics test paper shows new ideas and gives outstanding students more room to play. Although the presentation forms of many test questions are familiar to people, it does not mean that you can successfully answer them only by imitation and memory. Thinking about many problems requires candidates to have innovative thinking. For example, the problem 12 fuses straight lines, circles and plane vectors in analytic geometry. Although the entrance is very wide, only by careful analysis and comprehensive investigation of the relationship between algebra and geometry can we find a more reasonable solution.
For example, the function model obtained in item (2) of 17 may lead students to think of various schemes when seeking the maximum value, which requires careful thinking and analysis before they can step into the right path and avoid returning in vain. Although the calculation difficulty of these problems has not increased, it just depends on? Brush the questions? Accumulate experience in solving problems, it is inevitable that you will not be confused by appearances and miss the opportunity to score. For example, 14, 20(2) and 23 are all familiar to students, but they feel innovative when thinking, which provides excellent students with space to display.
4. Jiangsu's mathematics test paper pays attention to essence and examines mathematics ability. The examination paper not only pays attention to the examination of basic knowledge, general knowledge and general methods, but also examines the examinee's understanding of the essence of mathematics and the level of mathematical ability. The answers to some questions need to be based on the understanding of the essence of mathematics, so as to find the breakthrough point to solve the problem through phenomena. For example, 1 1~ 14, 18~20 can have different solutions, and the amount of thinking and calculation corresponding to each solution is very different. For the same problem, if the examinee is good at intuitive imagination and makes reasonable guesses, it is possible to find a relatively simple solution, and then it is possible to solve the problem by combining a certain form of logical reasoning or appropriate mathematical operations. But this series of work needs higher and more comprehensive mathematical ability to support.
How to learn high school mathematics;
1, each math problem is worth doing three times. You have to do every math problem (except the very simple one) three times. 1 is to do it normally, and then modify the answer according to the reference answer and problem-solving ideas. Doing it the second time is usually the best the next day. Do all the previous questions quickly. Do it for the third time, preferably after 7 days. After seven days, do it again at this time and you will feel suddenly enlightened. ?
2. There is a book to record your mistakes. The meaning of the wrong question book is not to copy every question you make wrong, but to save those questions that are wrong again and again. The essence of the wrong question book is a revision of our way of thinking and habits. The questions in this wrong book should all be wrong after three times.
It depends on the textbook. Many people think that middle school math textbooks may be the most important. Water? The textbook is so simple that everyone thinks the exercises in the textbook are not good. Why do you need to read textbooks when the answer is obvious? In fact, these people all know, but they don't know why. Let's think about a question, what is the college entrance examination? The college entrance examination is an exam with an outline, that is, you know all the exam ranges. So what is the scope of the college entrance examination outline? It is our textbook, so it is necessary to read it.
