First of all, we should carefully study what is learning efficiency. We haven't seen a clear definition yet. Efficiency is generally defined as the amount of work done per working hour. In other words, people who want to improve their learning efficiency are actually implying that working hours cannot be extended indefinitely. As far as learning is concerned, it also means that the current learning time is definitely not enough to complete all the learning tasks. One of the common misunderstandings in improving learning efficiency: the learning method recommended by the preview teacher is preview-lecture-review-homework-summary. It is required that when guiding children to learn, they should do these five links well, preview the difficulties of understanding, listen to lectures to understand the key points, review and solve doubts, comprehensively consolidate homework, and summarize and form a system. Ask children to "review before homework, preview before class, and think before asking questions." Now the problem comes out. There is not enough time to do homework, and we have to preview. There are 4-5 classes every day, and one class is previewed 10 minutes, which means one more hour. Where does this time come from? No one told us what the effect of previewing a course was. However, the requirement of preview is to find out the difficulties. When the teacher is giving a lecture, the difficulties only take up part of the time. This kind of preview is equivalent to saying that in a class, students only repeat their memories most of the time, and a small part of the time is the research difficulty. Common sense tells us that if they listen to what they already know, they will only get sleepy. Therefore, previewing in class, finding the key points and listening to lectures not only do not improve efficiency, but are wasted. It is the teacher who lets the students preview, which actually increases their study time in that course in disguise. The learning effect will be better, the teaching efficiency of teachers will be higher, and the learning efficiency of students will be lower. The second common misunderstanding of improving learning efficiency: concentrate on homework. Teachers will tell parents to improve time utilization. It is necessary to urge children to pay attention to the speed of learning, especially to concentrate on their homework. Don't look around and procrastinate. This sentence sounds right and beautiful, but it's just a harmful dream. Let's think about it. A student does 1 1 from 7: 00, and does homework for four hours in one night. Study 6-7 days a week. We should always focus on these four hours. Who can do that? Someone must be able to do it. Such a person must be a scholar in the future, but there is no 1-2 among 100 students. Most students can't do it. Most parents can't study for four hours. In the workplace, we will see this phenomenon. Generally, the workers on the production line are required to work continuously for two hours, with breaks in between. Do it for another two hours. However, engineers have no such restrictions. They can leave their posts at any time and go out for a cigarette and a cup of tea. You can chat with others. Why do bosses who value efficiency the most manage people like this? Because the workers on the production line are doing their work according to fixed procedures and habitual actions. I didn't think much. The work of engineers and technicians is mental work, and mental work cannot be highly concentrated continuously. Only by combining work and rest and being nervous and relaxed can we be efficient. Companies like Huawei will also have the concept of closed development. It was during the critical period that some engineers and technicians got together, eating and drinking Lazar were in the office, and all their energy was concentrated on taking out a project. This is very efficient and can only be used occasionally. Some time ago, an engineer of Huawei died of overwork, which caused social shock and the company was condemned by everyone. Look at the learned middle-aged people around us. Most of them have headaches and neurasthenia. Look at the students' teachers. How many of those good teachers are healthy? The reason is that traditional education allows these people to continue to use their brains a lot. In society, karoshi leads to sub-health. Therefore, in today's social environment, oppressing students to continue to concentrate on their studies will not only not improve their learning efficiency, but also seriously affect their physical and mental health and cast a shadow over their children's future. The third common misunderstanding of improving learning efficiency: it is right to make full use of spare time, but it has nothing to do with improving learning efficiency, because making full use of spare time is to increase learning time, not to increase the learning volume of unit learning time. What is the way to improve learning efficiency? To sum up in one sentence is "find out the weak links in learning and try to solve them." The ultimate embodiment of improving learning efficiency is high test scores. We have made statistics on Chinese, mathematics and English in about 300-500 test sites. There are about 200 test sites in physics and about 100 in chemistry. Most students can master about 70% through classroom study and assigned homework, that is to say, a student who goes to school normally without extra homework and extra tutoring has an average score of about 70 points. If you want to keep improving your grades, you must take other measures. Unfortunately, the current teaching system is to increase the amount of homework, participate in many cram schools, and improve grades through massive exercises. In other words, it is to increase the study time to complete. The price is that students are exhausted and have good grades, but they have no time to cultivate other qualities. The overall quality is getting worse. The problem is actually very simple. Since students can't master many test sites, why not help them find out and solve them? The first is how to find the difficulties and weaknesses of children's learning. This work is relatively simple to do, but the workload is heavy and hard, and parents can help. These problems and weaknesses exist in homework and test papers, and those wrong questions are children's weaknesses. Nowadays, many parents help their children sort out their homework papers, bind them well, mark those wrong questions, or copy them out and do them again every once in a while. Then sort out inappropriate topics. Those students who are more careful will do the same themselves. The second is how to solve it? This job is difficult to do, and parents have many misunderstandings. I often hear parents complain that their children always make mistakes in the problems they can do, or that their children are too careless. Actually, this is a misunderstanding. These weak links are difficult for students to overcome. It is not easy to solve, and it is often in a specious state. What is right today may be wrong tomorrow. Essentially, there is no mastery. We often see on TV that it takes hundreds of times for an athlete to practice an action to be perfect. We also know that no matter how smart a person is, he will write down his name anytime and anywhere. The reason is that practice makes perfect. According to statistics, a problem that students are prone to make mistakes must be repeated more than 50 times before they can finally master it. So we should make great efforts to solve this kind of problem. The essence of learning is memory. Now we can use some tools and software to help train and improve students' own memory ability, thus greatly improving learning efficiency, such as training professional software for fast reading and fast memory. Expert research shows that the reading speed of ordinary people is about 240-280 words per minute. After professional training, it can be quickly improved to 1500-3000 words per minute, even reaching the international level of tens of thousands of words. At the same time, the absolute amount of memory will increase several times to ten times, and the learning efficiency will of course be greatly improved. It can be seen that people's memory potential is great. Of course, it takes some time to train such a special ability, but "sharpening the knife does not mistake the woodcutter." In addition, many parents like to find tutors outside the school for their children, which is also necessary. However, a few points should be noted: (1) It is better to invite retired teachers instead of in-service teachers. In-service teachers are often busy with their work. If they are also teachers of students, they will have great short-term behavior. On the contrary, retired teachers spend more time and care about their own image, so they spend more time and energy on their students. Family education emphasizes slow work and fine work. (2) Find a teacher with fewer retired teachers and students. There are naturally many students with good teachers. Some tutors have prepared a big room for their students. Like a class. This effect is very poor. Because as we said, it takes a lot of effort and skill to find a teacher to help students with intractable diseases. Many students are different from each other. The teacher can't control it. Conditional parents can raise tuition fees for make-up classes by themselves and ask teachers to reduce the number. It is best for one teacher to tutor 2-3 students. (3) Mentors should be long-term. Only after a long time can the tutor know the roots of the students and be targeted. In addition, solving intractable diseases is not only a question of teaching ability, but also some psychological suggestion skills. A pair of teachers and students who cooperate tacitly and get along well are naturally efficient. (4) Parents should fully communicate with their tutors. Knowledgeable parents should have the ability of overall planning. As mentioned above, it is the parents' responsibility to find students' learning problems first. Fully communicating this information with teachers is also a way to supervise and coach teachers. Similarly, the tutor is more targeted and more efficient. If parents don't have the ability and time to find students' difficult problems, they should always contact the students' teachers at school to listen to their opinions and then communicate with the tutors. Can listen regularly. You must listen more and talk less when talking to the teacher. Some parents can't finish talking, and it's useless to say happy. On the contrary, after letting the teacher speak, the teacher will give birth to some new ideas and new tricks. This is in the best interests of students. At this point, we have come up with an overall plan to improve learning efficiency: a relaxed, free and harmonious family learning atmosphere.
