Follow the teacher in class, be sure to be serious. So it is no problem not to review after class.
As long as you get to the point, you will never do too badly in the exam. When you can't do it at ordinary times, take a break and try from another angle. It's best not to ask others. Others must be corrected by themselves.
As for the math book ... it has never been used. ...
In fact, doing more math problems is just to consolidate memory, in my opinion. I think mathematics should be analogized, doing a problem and passing a class of problems. Instead of doing a hundred questions, understand one question. I'd rather spend the time of doing one hundred questions on one question and one class of questions.
I think many people study mathematics just to reverse this concept. We should spend time thinking, not doing many problems. Do a problem and you'll be done. If you want to know what this question is about, what concepts are involved, what formulas are used, how to turn other conditions into unknowns, how do you get it, from the front, or by reducing to absurdity? Wait, these, if you have thought about them all, you will understand a kind of problem.
Mathematics, physics, chemistry and other sciences are not Chinese, so it is not enough to remember as much as possible. Understanding is the most important thing, of course, this does not mean that you don't remember anything. Everything you learn is to remember something, which cannot be changed. I used to do this. You can learn to watch. See if you think it applies. All the formulas in your certificate. Although there are many proofs in the book, what I mean here is that you'd better prove it in other ways. If you can't prove it yourself, you must also know the proof in the book. I used to have several theorems in mathematics (junior high school) that I couldn't prove.
There is also the first thing you have to deal with: pay attention to adjusting your emotions! You can choose your attitude at any time, depending on whether you choose to be positive or pessimistic.
I like math since I was a child, and now I major in math in college. Personally, I think:
1, I don't agree with the policy of going to the sea (maybe because I'm lazy).
I think, if you want to learn math well, you should listen carefully. What the teacher said is very important.
3, mathematics should be a basic subject, as long as the foundation is good, you can learn well.
4. Do the topics that the teacher said after class, and do up to three questions for each type. I just said that I don't agree with the sea policy, that is, some people keep doing the same type of questions because they think the questions are easy. I think it's useless, just like not doing them. Don't be afraid to do the problem. I think the more difficult the math problem is, the more worth exploring.
The most important thing is to cultivate interest in mathematics. Interest is the best teacher.
A high school math teacher told me to ask more questions and do more exercises if I don't understand. I hope it helps you.
I am self-motivated and have goals in mathematics. Of course I can move towards that goal. Believe in yourself!
When you look at the problem, you want to have anything to do with the textbook, so you find the starting point.
As soon as you finish a problem, you can use "reverse thinking" to get the result back, which can ensure the efficiency of doing the problem!
I am lazy and never do many problems. In fact, most of the high scores in mathematics are in the basic part, and the problem depends on thinking. It is very easy to find the rules and basic points of these questions. The school papers are enough for you to exercise your thinking. I wish you good grades in math. Oh, by the way, don't be nervous about doing the test paper. What's the difference between skin thickness test? Of course, it's not really bad for you. Just try it. I don't know if it will help! I think it will be useful.
First of all, teachers must listen carefully and finish their homework carefully, which is a necessary condition for learning mathematics well, and its importance goes without saying. In addition, the school sometimes orders some teaching AIDS for students, which can be fully utilized. Some extraordinary students can strengthen the depth and breadth of learning, but the basic skills-basic knowledge can never be ignored.
Secondly, we should pay attention to efficiency. Don't do "repetitive work", each preview should have a clear purpose. Here, I want to make it clear that too many reference books are unnecessary. Reading one reference book is often better than reading two, but not reading it. The famous mathematician Hua said: "When reading, the more you read, the thinner you get." In other words, we should grasp the basic clues and spiritual essence of the commander-in-chief book.
This reminds me that every student is weaving a knowledge network for himself while learning knowledge. Its main function is to link what he has learned and improve learning efficiency. Knowledge networks should be properly woven. Too sparse, can not let their thinking extend in all directions, free; Too dense, it will affect the clarity of the main line, not worth the loss. Let's take an example here: a classmate usually studies hard and does a lot of math problems, but he doesn't understand the main idea. In order to "leak-proof", he takes almost every sentence in every reference book as the focus. What is more sad is that in the process of repeated work, he never arranges his long thoughts in an orderly way, and some questions asked by teachers and classmates are often "low-level"-just turn his head a little! Because he doesn't pay attention to the sense of solving problems, his grades have not improved, which is the consequence of the book "getting thicker and thicker". Mathematics problem-solving is often very flexible, and everyone has their own problem-solving ideas to improve learning efficiency.
Many math problems are intriguing. Solid geometry allows us to understand the art of space, and mathematical induction allows us to appreciate the skills of proof ... China football team coach milunovic advocates "happy football", so we might as well enjoy mathematics and experience the fun it brings. Think more, enjoy more and gain more. This is my third point. In the usual study, you must leave a considerable number of topics for yourself to fully think about, especially the more difficult ones, even if you think for an hour or even longer. To solve a difficult problem, as long as it is fully considered, even if it is not done, the whole thinking process is valuable. Because difficult problems are often comprehensive and have strong ability, and require high continuous divergent thinking, solvers often have a long exploration process. In the whole process of exploration, problem solvers keep looking for breakthroughs, constantly hitting a wall, constantly adjusting their thinking power and making progress. At the same time, the problem solver tried a lot of knowledge and skills he had learned, which had a good review effect. Problem solvers also test their mastery of relevant knowledge by doing problems, so as to set a suitable goal for their future study. I remember that there is an inequality proof problem in the magazine "Middle School Mathematics", which is quite difficult. I thought hard for four hours and finally came up with a better plan than the reference plan. This makes me ecstatic, and of course it also gives me a deeper understanding of this inequality. By the way, thinking more is a good way to cultivate a person's comprehensive ability in mathematics, but some students often ignore the calculation ability and practice. Although calculators can be used in exams (not in competitions), calculators cannot perform algebra, analysis and trigonometry. Unfortunately, sometimes the students' thinking of solving problems is right, but the calculation is wrong, which leads to the final mistake. One of the reasons why I am not good at analytic geometry is that it requires a lot of calculation. If the method used is not good, the calculation will be more complicated and error-prone. I hope readers will work together with me to make themselves have excellent computing ability.
In addition to the above three points, I think, whether in the learning process or in the review stage, we should pay attention to the adjustment of mentality. There are many reasons for failing an exam. It may be that the knowledge is not firmly mastered, that the problem-solving feeling is not in place, that the calculation mentioned above is incorrect, that the state is not good, that it may be a special reason, and that it may be too eager to take the exam.
