Methods to improve the efficiency of mathematics review in college entrance examination
Pay attention to basic review.
If senior three wants to review senior high school mathematics effectively, we must first start from the most basic. High school math review is like Gai Lou. After that, when the foundation is laid, the building can be built tall and stable. Therefore, it is very important to pay more attention to the review of basic knowledge, but some students may ask, what is the so-called basic knowledge of high school mathematics?
The basic knowledge of high school mathematics is the knowledge points listed in our review materials. However, your friends in senior three must pay attention not to memorize the basic knowledge of high school mathematics, but to learn to understand and remember. Because you want to use this knowledge to do the problem, only on the basis of understanding these mathematical knowledge can you better apply these basic knowledge.
Listen carefully in class.
It is important to listen carefully in math class. High school mathematics can't be learned if you want to learn it well. Learning takes you a lot of time, and your learning methods are not necessarily very effective. Senior high school math teachers are experienced. They will help students learn high school mathematics in the shortest time and in the most effective way. Therefore, if you want to learn high school mathematics well, you must learn from the experience of high school mathematics teachers to improve yourself. It is very important to listen carefully in class.
On the other hand, high school mathematics is also a high-tech thing. If you don't attend classes, you may never master a mathematical idea, a high school mathematics learning method.
Do more exercise.
As the saying goes, practice makes perfect. Therefore, in order to improve the efficiency of high school mathematics learning, we must practice more exercises at ordinary times. For example, you have mastered a learning method of high school mathematics, but you didn't spend time on it. Maybe you did do this kind of problem at that time, but it may not be long before you forget it.
Therefore, if you want to remember something deeply, especially the knowledge points of high school mathematics, then you must do more and often do some related math exercises to practice and remember. This can better grasp the knowledge of high school mathematics and improve the review efficiency.
A summary of mathematics review methods in college entrance examination
First, remember in time after class.
If you forget the content in class, it is almost equivalent to relearning, so you must review the new knowledge you have learned in class in time.
One person can recall, or several people can inspire each other and supplement the memories together. Generally, according to the outline and essentials of the teacher's blackboard writing, or according to the outline structure of the teaching material, the review is carried out step by step from the topic to the key content to the details of each part of the example. In the process of review, we should lose no time in sorting out notes, because sorting out notes is also an effective review method.
Second, repeat and consolidate regularly.
Even the reviewed content should be consolidated regularly, but the number of reviews should be gradually reduced with the increase of time, and the interval can be gradually lengthened. You can consolidate new knowledge on the same day, make weekly summary every week, make periodic summary every month, and conduct comprehensive and systematic semester review at the middle and end of the semester.
From the content, we should immediately review the knowledge of each lesson, sort out the knowledge of each unit, summarize the knowledge of each chapter, connect the relevant knowledge in series, form a knowledge network, and grasp the knowledge and methods as a whole.
Third, scientific and reasonable arrangements.
Review can generally be divided into centralized review and decentralized review. Experiments show that the effect of decentralized review is better than that of centralized review except in special circumstances. Decentralized review can properly classify the materials that need to be memorized and alternate with other studies or entertainment or rest, so as not to use a certain way of thinking monotonously and form fatigue.
Decentralized review should also combine your own cognitive level and the characteristics of memory materials, and grasp the number of repetitions and the interval. The longer the interval, the better, but it should be suitable for your own review rules.
Effective review methods of college entrance examination mathematics
Combination of numbers and shapes:
"Number" and "shape" are the two most important cornerstones of the tall building of mathematics. They are interrelated in content, infiltrated in methods and can be transformed into each other under certain conditions. The combination of numbers and shapes is developed on the basis of mathematical characteristics. In the process of solving multiple-choice questions in mathematics, we can draw a sketch according to the meaning of the question, and then refer to the practice, shape, position and nature of the figure, and synthesize the characteristics of the image to draw a conclusion. This method is not only convenient for solving problems, but also easy for people to understand.
Direct comparison method:
Starting from the setting conditions of mathematical problems, we use the known conditions, related concepts, properties, formulas, axioms, theorems, rules and other basic knowledge. Through strict reasoning, accurate operation and reasonable verification, the correct conclusion can be drawn directly, and then the correct choice can be determined by comparing the options given in mathematical problems.
Screening method:
Get rid of the false and keep the true, abandon the options that do not meet the requirements of the topic, and find the correct conclusion that meets the meaning of the topic. Screening method (also known as exclusion method) is to exclude the wrong mathematical options one by one by observing, analyzing or reasoning the information provided by each item, or through special circumstances, so as to draw correct conclusions.
