Why do math scores drop after entering high school? Please tell me the old saying: Give people fish, and only have one meal. Give people fish, and you will benefit for life. Learning knowledge requires learning methods. The column of learning methods in Tsinghua Online School is composed of many years' teaching experience and excellent students' learning experience, which aims to help students develop good study habits and get twice the result with half the effort. Some people describe mathematics as "gymnastics of thinking, sparks of wisdom". As an important subject to measure a person's ability, most students from primary school to high school have a special liking for it and have invested a lot of time and energy. However, entering the high school stage, many excellent students in primary and junior high schools are stumbling in mathematics for the first time. There are many reasons for this phenomenon. Let's listen to the teachers of online schools in primary and secondary schools affiliated to Tsinghua University to talk about how to learn high school mathematics well from the perspective of students' learning status. First, the reasons for the decline in math scores after entering high school. Many students do well in math in junior high school, but their math scores drop sharply after entering senior high school. According to their general learning state, the main reasons for their decline in grades are as follows: 1. Passive learning Many students are still like junior high school after entering high school. Such as: not making plans, waiting for classes; Do not preview before class, do not understand what the teacher wants to do in class; Busy taking notes in class, I can't hear the "doorway" and I don't really understand what I have learned. 2. Teachers who can't learn regularly should generally explain the ins and outs of knowledge, analyze the connotation of concepts, analyze key and difficult points, and highlight thinking methods. However, some students didn't concentrate in class, didn't hear the main points clearly or didn't listen completely, took a lot of notes and had many problems. After class, I can't consolidate, summarize and find the connection between knowledge in time, just write my homework in a hurry, do problems in disorder, have a little knowledge of concepts, laws, formulas and theorems, mechanically imitate and memorize; Some people work overtime at night, are listless during the day, or don't listen at all in class, so they have another set. The result is half the effort, with little effect. 3. Some students who don't pay attention to the foundation and feel good about themselves often despise the study and training of basic knowledge, skills and methods. They often forget what to do, but they are interested in the difficult problem of showing their "level" and ambitious, either making mistakes in calculus or giving up halfway in formal homework or exams. 4. Advanced study conditions do not have high school mathematics. Compared with junior high school mathematics, the depth, breadth and ability of knowledge are all a leap. This requires students to master basic knowledge and skills to prepare for further study. Many parts of high school mathematics are difficult, with new methods and high requirements for analytical ability, and some contents are still out of touch in the textbooks of high school and junior high school. If remedial measures are not taken in time, division is inevitable. Second, it is not enough to master the initiative and learn high school mathematics well. It is also necessary to "learn". Only by paying attention to scientific learning methods and improving learning efficiency can we turn passivity into initiative. Cultivating good study habits Good study habits include making plans, self-study before class, paying attention to class, reviewing in time, working independently, solving problems, systematically summarizing and studying after class: (1) Making plans to make the learning objectives clear and the time arrangement reasonable and steady is the internal motivation to promote students' active learning and overcome difficulties. But the plan must be practical, with both long-term plans and short-term arrangements. In the process of implementation, we must be strict with ourselves and hone our will to learn. (2) Self-study before class is the basis for students to learn new lessons well and achieve better learning results. Self-study before class can not only cultivate self-study ability, but also improve interest in learning new lessons and master the initiative in learning. Self-study should not go through the motions, but pay attention to quality, try to understand the teaching materials before class, pay attention to the teacher's ideas in class, grasp the key points, break through the difficulties and solve the problems in class as much as possible. (3) Listening attentively is the key link to understand and master basic knowledge, skills and methods. "Learning is not enough", students who have taught themselves before class can concentrate more, and they know where to be detailed and where to omit; Where to carve carefully, where to pass by and where to record, instead of copying all the records, pay attention to one thing and lose another. (4) Timely review is an important part of efficient learning. By repeatedly reading textbooks and consulting relevant materials, we can strengthen our understanding and memory of basic concepts and knowledge systems, link the new knowledge we have learned with the old knowledge, make analysis and comparison, and arrange the review results in our notes while reviewing, so that the new knowledge we have learned can be changed from "understanding" to "knowing". (5) Independent homework is a process in which students can analyze and solve problems flexibly through their own independent thinking, so as to further deepen their understanding of new knowledge and master new skills. This process is a test of students' will and perseverance. Through homework, students can change from "knowing" to "being familiar with" what they have learned. (6) Problem-solving refers to the process of smoothing thinking and supplementing answers by enlightening the exposed wrong knowledge or missing answers due to blocked thinking in the process of independently completing homework. Perseverance is needed to solve problems, and homework should be done again if it is wrong; If you don't understand the mistakes clearly, you should think again and again. If you can't solve them, you should consult your teachers and classmates. We should always review the mistakes that are easy to make, insist on "familiarizing" what we have learned, and "live" it for a long time. (7) Systematic summarization is an important link for students to master knowledge comprehensively, systematically and profoundly and develop their cognitive ability through positive thinking. In summary, on the basis of systematic review, textbooks, notes and related materials, through analysis, synthesis, analogy and generalization, the internal relationship between knowledge is revealed, so as to achieve the purpose of mastering the knowledge learned. Frequent multi-level summary can change knowledge from "living" to "understanding". (8) Extracurricular learning includes reading extracurricular books and newspapers, participating in academic competitions and lectures, and visiting senior students or teachers to exchange learning experiences. Extracurricular learning is a supplement and continuation of in-class learning. It can not only enrich students' cultural and scientific knowledge, deepen and consolidate what they have learned in class, but also satisfy and develop students' hobbies, cultivate students' autonomous learning and working ability, and stimulate students' thirst for knowledge and enthusiasm for learning. Step by step to prevent impatience. Because students are young and have limited experience, a large number of high school students are more prone to impatience. Some students are insatiable, eager for quick success, some students want to "sprint" in a few days, some students are complacent when they achieve a little, and they will never recover when they encounter setbacks. In view of these situations, teachers should let students know that learning is a long-term accumulation process of consolidating old knowledge and discovering new knowledge, which can never be achieved overnight. A very important reason why many excellent students can get good grades is that their basic skills are solid, and their reading, writing and computing abilities have reached the level of automation or semi-automation. 3. Study the characteristics of the subject and find the best learning method. Mathematics is responsible for cultivating students' computing ability, logical thinking ability, spatial imagination ability, and the ability to analyze and solve problems by using what they have learned. It is characterized by a high degree of abstraction, logic and wide applicability, and requires high ability. Learning mathematics must pay attention to "living", not only reading books without doing problems, but also burying oneself in doing problems without summarizing and accumulating. We must be able to access textbook knowledge and find the best learning method according to our own characteristics. This is why Mr. Hua advocates the learning process of "from thin to thick" and "from thick to thin". Methods vary from person to person, but four steps (preview, class, arrangement and homework) and one step (review and summary) are indispensable. 4. Strengthen counseling and resolve differentiation points. There are many easy differentiations in high school mathematics. These places generally have the characteristics of new methods, great difficulty and strong flexibility.
Why do children's grades suddenly drop at the beginning of junior high school? Parents should find parents to put too much pressure on their children. If children study well, let them relax more. Give him more pressure if his grades are poor. Be sure to play it by ear.
Cancel the promotion of children with good grades. What should I do if my child gets good grades? They won't be buried anywhere. There will be no promotion. At that time, they will mainly look at the exam results of Xiaoshengchu. Those who do well in the exam can be assigned to good schools and good classes.
Why did my child lose so much weight after breastfeeding? What should I do? Baby is easy to lose weight after weaning, mainly because he is used to breast milk and doesn't like complementary food. You should cook different flavors of food for your baby every day, cultivate your baby's interest in eating, and let your baby fully absorb nutrition.
How should children prepare for junior high school? Urgent! By the third and fourth grades, my children have started to learn English systematically. The task of this stage is to systematize the knowledge learned, accumulate knowledge points such as grammar, words and phrases, and expand the understanding of English.
The fifth and sixth grade of primary school is the key period to improve comprehensive ability. During this period, children will face the comprehensive application of what they have learned for the first time, and the focus of learning will change from "indoctrination and recitation" to "application and feedback".
I'm in junior high school, but I'm a little more nervous than primary school, and there's nothing wrong with everything else. The main thing is to cultivate good habits. Get up early in the morning and take a lunch break at noon.
My children are not good at math, but they are good at other classes. Facing junior high school, how should children improve their grades? The child usually does well in other classes, which shows that his liberal arts is still ok. I suggest your children read the rest of the story book, which contains many math stories and can help children develop their intelligence. Parents can also buy them in bookstores or online. It is the key to attract children's attention, and it is also a good choice to let children think often.
