Mathematics is the hard bone in the college entrance examination. Many students who have participated in the college entrance examination say that they are very disadvantaged in mathematics, so it is particularly important to learn mathematics well. The most important thing in high school mathematics is one word-enlightenment!
Is high school math difficult? What's the hardest part?
1 which part of high school mathematics is difficult?
1, the most abnormal or even abnormal finale of high school mathematical algebra-inequality+series (strongly stated: it is a big question, not a multiple-choice question, and the multiple-choice question of the series is not too difficult), it is said that the finale questions are all changed from Olympic numbers.
2. Mathematical geometry in high school is the most abnormal, stable and obscene (because it is obscene whether it is multiple-choice questions, fill-in-the-blank questions or big questions)-plane analytic geometry. (Inequality+sequence thinking is difficult, and analytic geometry calculation is difficult. Many times you know how to calculate, but you can't write it. There is too much ink! What a waste of draft paper! )
Legend is hard-solid geometry. If the spatial thinking is good, adopt the general method; If it is not good, it depends on the space vector. But the first contact of solid geometry is weak, get used to it.
4 What needs the most strength (I think)-permutation and combination. Belongs to the general examination (see what area, like Tianjin Juan, rarely vomiting blood), which generally hurts self-esteem. Because you can work it out, but there is a gap with the answer. But it is also a habit.
The biggest difference between high school mathematics and junior high school mathematics is systematicness. High school mathematics is very systematic, so it will lead to the first paragraph not being understood and the second paragraph not being understood. About stupidity, it's actually not a big problem. Can be admitted to high school normally and have normal intelligence. The most important thing to solve these problems is to grasp the foundation. Go back to the textbook. Don't look down on textbooks, thinking that things in textbooks are simple and unwilling to learn or write. In fact, most of the topics are adapted from textbooks.
Moreover, after entering high school, the difficulty of textbook topics is not the same as that of junior high school classes, and many textbook topics are still very difficult and worth writing. Temporary hardship does not mean eternal hardship. You should believe in yourself. Mathematics is not a very simple subject. Things in junior high school are actually very few and simple, so don't give up. As everyone knows, you can't understand. In fact, many students are silent. There are still many people who pretend to understand or give up completely. Learn to ask the teacher, believe in yourself and practice more. I believe you will overcome the temporary difficulties.
2 Analysis of the difficulty of high school mathematics
Some students feel that they have heard what the teacher said clearly. But why is it so difficult to do the problem by yourself? The reason is that students' understanding of what the teacher said has not reached the level required by the teacher.
Therefore, before you do your homework every day, you must read the relevant contents of the textbook and class notes first. Whether you can stick to this point is often the biggest difference between good students and poor students.
Especially when the practice is not well coordinated, there are often no questions in the homework that the teacher has talked about, so it is impossible to compare and digest. If we don't pay attention to this realization, it will cause great losses over time.
Students must make it clear that the topic they are doing now is definitely not the topic of the exam. But to use ideas and methods to solve the problems we are doing now. So we should reflect on every question we have done and sum up our gains.
To sum up: what is the content of this question and what method is used. Turn knowledge into pieces and questions into strings. Over time, build a scientific network content and method system.
As the saying goes, "money is hard to buy." We think it is very valuable to finish your homework and look back carefully. Review is a very important link in the learning process.
See if you did it right; What other solutions are there? Where is the topic in the knowledge system? What is the essence of the solution; Whether what is known and what is sought in the topic can be interchanged, and whether it can be added or deleted appropriately. With the above five reviews, students' problem-solving ability can increase day by day. Although the time invested is very small, the effect is great.
It is very important to summarize the chapters. In junior high school, it is the teacher who gives the students a summary, which is meticulous, profound and complete. In the third year of senior high school, I made my own summary, but the teacher not only refused to do it, but also said where to take the exam, where to take the exam, leaving no review time, and did not clearly point out the time to make the summary. How to make a chapter summary?
(1) Read the textbooks, notes, unit test papers and test papers from beginning to end. Mark while reading, indicating which ones to extract later. To form a habit, mark the material at any time when reading it, and tell yourself the main points of reading the material next time.
(2) The content of this chapter is divided into two parts, one part is basic knowledge and the other part is typical problems. It is necessary to list the requirements for skills in one of these two parts, and don't leave them out.
(3) When sorting out the basic knowledge, we should list all the definitions, theorems, rules and formulas we have learned. It takes three sessions and two uses. That is: know how to represent characters, know how to represent symbols, and know how to deduce proofs. At the same time, it can be used in both positive and negative aspects.
(4) Forming important typical problems. We should classify them as much as possible, find out the positional relationship between them, and sum up the cause and effect of the problem.
(5) Summarize the unclassified questions and make supplementary explanations as remarks.
(6) Find a suitable test paper. Be sure to do a time test. Then check the answers and fill in the blanks.
