Let me talk about my personal experience first. I was in the top ten in junior high school and was admitted to a key high school with the second place in our class. After one month of school, I got 62 points in math, out of 150. At that time, he gave me a special look when handing out the examination papers. I know the reason, because our student numbers are ranked according to the entrance ranking, so we got such a test.
Let's talk about the reasons for the decline in math scores in Grade One.
1, the learning content has changed a lot.
Mathematics in senior one is an extended study based on the function content in junior high school, but the knowledge of mathematics in senior high school is wide, difficult and abstract, mainly because the textbook content is not too difficult. The learning content of senior one mathematics, such as set, function, trigonometric function, vector, etc., can also be understood, but the topics and examination contents of various materials after class will be extended on the basis of the textbook, so we will simply do examples and exercises in the textbook.
2. Learning tasks have increased, and teachers' teaching methods and learning requirements are different.
When dealing with high school textbooks, high school teachers don't have enough time to repeatedly emphasize the content of textbooks, and basically do a lot of expansion. It is difficult to learn high school mathematics well simply by "drawing inferences from one instance", and it is necessary to master the ability of "drawing inferences from another instance". There is a metaphor that can vividly explain the difference between junior high school and senior high school:
In the junior middle school class, the teacher teaches you a lesson of mixing noodles, homework and noodles; A class teaches you paper and homework; I won't eat jiaozi until I teach you to eat jiaozi. In high school, the teacher taught you to pack jiaozi in one class. Homework is steaming steamed buns at home, and the exam is baking pies.
Mathematics in senior one is difficult to learn. It is not enough for junior high school students to simply attend classes and do homework. This requires us to mobilize our attention and take it seriously:
1 Of course, listening is the main thing. Listening can make you concentrate, so you should understand and listen to the key parts of the teacher.
Pay attention to thinking and analyzing problems when listening, but only listening without remembering, or just remembering without listening, it is inevitable to pay attention to one thing and lose sight of another, and the classroom efficiency is low. Therefore, we should take notes appropriately and purposefully to understand the main spirit and intention of the teacher in class. Scientific notes can improve the efficiency of four 5-minute classes.
2. Improve math ability, of course, through the classroom, and make full use of the classroom.
The process of learning mathematics is alive, so is the object of teachers' teaching, which changes with the development of teaching process, especially when teachers pay attention to ability teaching, and the teaching materials cannot be reflected.
Mathematical ability is formed simultaneously with the occurrence of knowledge. Whether forming a concept, mastering a law or doing an exercise, we should cultivate and improve it from different ability angles. ?
3. Typical problems must be focused on.
In math class, teachers usually ask questions and perform, sometimes accompanied by discussion, so they can hear a lot of information. These questions are very valuable. For those typical problems, problems with universality must be solved in time, and the symptoms of the problems cannot be left behind or even solved. Valuable problems should be grasped in time, and the remaining problems should be supplemented in a targeted manner and pay attention to practical results.
What impressed me most about high school mathematics is that even if you listen carefully in class and feel as if you understand it, I will find that I still won't take the exam, because the content of the investigation is extended, not just the application of knowledge points. Therefore, after-school review is particularly important:
1, remember it 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.
At that time, I was a few people in the back table who inspired each other and supplemented their memories, mainly through after-school exercises and homework, and exchanged yesterday's ideas. It's actually very difficult at first, because you can't understand other people's ideas and you can't say your own clearly. Later, I slowly run in and feel that this method is still very good, which can broaden the thinking and skills of solving problems.
2. Repeat consolidation regularly.
Although high school mathematics is difficult, the knowledge points are still coherent and can overlap each other, which requires us to truly understand the relationship between knowledge points. I find that repeated consolidation sometimes leads to unexpected gains. For example, the set problem is actually a logical problem. Through the knowledge points of finite set and infinite set, the answer can be found in the problem.
It's normal for senior one students to fall down in math, so there's no need to be too entangled. Find a suitable learning method, brush a lot of questions and you will find your feeling of answering questions, and it will be much easier to learn in the future. Welcome students who have good methods to communicate with each other.
