Don't listen in class, to put it bluntly, you don't concentrate. There are many reasons for inattention in study. Let's see which one you belong to first. First, the purpose of learning is not clear enough. Second, the learning content is too difficult, the learning burden is too heavy, and the psychological pressure is too great. Third, the content of learning is too easy. You know it by heart, and you are tired of learning it over and over again. Fourth, fatigue, the brain has not been fully rested. No matter what causes the inattention in learning, as long as you try the following methods, you will have a certain "curative effect": First, go to bed early and get up early to decompress yourself. Try to make full use of daytime study, improve the study efficiency per unit time, and don't stay up late because you are too tired to get up all day. At the same time, don't take exam results too seriously. No pains, no gains. I believe that as long as you work hard on weekdays, there will be good returns. In this way, when studying, you can feel relaxed and happy, and your attention is easy to concentrate. Second, clear objectives and use good methods. From a big perspective, we should realize that studying hard today is to create a better tomorrow and become useful people to our family and society. From a small point of view, what learning tasks should I complete this year, this semester, and even this day? If the goal is clear, the motivation for learning will be enough, and the attention will not be easily distracted. We should really pay attention to using some better methods to train ourselves to concentrate and improve learning efficiency: 1. Relaxation training. Sit comfortably in a chair or lie in bed and send rest information to all parts of the body. Start with the left foot, make the leg muscles tense, then relax, suggesting that it is resting, then relax from the right foot to the trunk, and then from the left and right hands to the trunk. At this time, relax from the trunk to the neck, head and face. In just a few minutes, you can enter a relaxed and peaceful state. 2. Moderate difficulty method. For those exercises that have been skillfully answered, don't calculate repeatedly, but find some classic problems in this field to overcome. For more difficult topics, think independently first, and then ask teachers, classmates or parents for help. For the content that is not interesting and difficult, we should first make a good plan and limit our study time, so as not to relax and delay. If you win a "mountain" in your study, give yourself a reward and let your sense of accomplishment motivate you to concentrate. 3. Senses are used in the same way. Mobilize a variety of motor organs to coordinate activities and form a strong excitement center in the cerebral cortex. For example, listen to tapes, read words with your mouth, read textbooks with your eyes, and write words on paper with your hands. In this way, attention can't be a "deserter". 4. Elimination of interference method. Recite an article of 200-400 words without any interference, and see how long it will take. Then recite this article with interference, and see how long it will take until the time in the two environments is the same. 1. Go to bed early. Get up in the morning and have some coffee. 3. Wash your face after class and stimulate with cold water. 4. Be sure to sleep at noon. If you follow the above methods, you must sleep for 8 hours if you are not sleepy in class for a week. If you try to take notes in class, you can concentrate on the class. Note: Mathematics is a course to cultivate thinking and the foundation of other sciences. First of all, you should learn math well. The simplest way to learn is: in fact, students should focus on learning and develop in an all-round way. There is no end to learning, and diligence can make up for it. Improve learning methods. In the process of learning. Remember more (remember concepts, remember formulas), read more (read books), do more (do homework), ask more (ask if you don't understand), do more (do experiments), review more and summarize more. ....
