How to adapt
study
With the deepening of learning, the differentiation of math scores is inevitable, so what are the reasons for falling behind? How should freshmen who have difficulties in math study get through the adaptation period smoothly?
One reason
and
Compared with, the difficulty has improved, so there will be a small number of new ones.
I can't get used to it for a while. Can understand in class, can't write homework; Or even if I did, the teacher didn't know there were many mistakes until I changed it. This phenomenon is dubbed as "understanding at first sight, and being wrong at first sight". Therefore, some
Think the child is there
The exams are all close to full marks. How did you get here?
Fail the exam? !
Coping methods should thoroughly understand the contents supplemented by books and teachers in class, sometimes think and study repeatedly, draw inferences from others on the basis of understanding, and ask questions on the basis of diligent study.
The second reason is that junior high school and senior high school have different requirements for mathematics at different learning stages. The average score of the senior high school entrance examination is generally around 70. If there are 50 students in a class, there will generally be less than 10 students who fail, and the number of students with a score of more than 90 is very small. Some students and parents don't understand these situations, and they feel incredible about the grade gap in Grade Three and the failure in Grade One.
Students and their students
The pressure is particularly high.
Coping methods can't just look at students' grades.
The key depends on the relative position of the class or grade, but also on the location of the school where the students are located in the city. Comprehensive consideration will lead to psychological balance, and unnecessary burdens will follow.
The third reason is the inadaptability of learning methods.
Compared with junior high school, it has many contents, fast progress and difficult topics, but the homework in class is often difficult to understand.
Due to various subjects
They are too old to review effectively, and the phenomenon of forgetting before school is more serious.
We should not only understand the coping methods in class, but also write down the contents added by the teacher properly. After class, it is best to digest what you have learned before doing your homework. Don't look at notes or formulas when you do the problem. Try to choose some related questions to practice after class.
.
Reason four: I relaxed my mind. Because I studied hard in grade three, I went to grade three.
I have the idea of relaxing, because there are still three years before the college entrance examination, especially some students who desperately make up classes in senior three, and they still expect "
"This is a very dangerous idea. If the foundation of senior one is too poor, expect senior three to assault, and practice shows that most of them.
Failure. Some smarter boys
Problem-solving only pursues the correctness of the answer, writing is not standardized, and scores are seriously lost in the exam.
We should not slack off in dealing with the curriculum content of senior one, and function knowledge runs through senior high school mathematics from beginning to end.
It is also a sharp weapon to solve many problems. Learning functions well is very important for the whole senior high school mathematics, and we can't relax. You should cultivate diligence and assiduousness from the first year of high school.
, rigorous and serious
And the method is important. There are more than ten chapters in high school mathematics.
Mainly function. Some students don't learn function very well, but they are in Grade Two.
、
But they can learn well, so we must treat students with a changing point of view. Encouragement and confidence will never fail.
Treasure.
Basic theory+appropriate exercises:
The most basic knowledge will be understood in class and the principle will be understood.
Make it clear. Because all college entrance examination questions are variations of basic principles, especially functions, which are basic knowledge and required contents, the most direct way to master the basic principles is to do all the textbook examples three times by yourself, complete them independently, compare the differences with the solutions of the examples and find your own knowledge.
.
The problem must be solved, but to get the so-called "problem", you need to find out where you are wrong, whether the basic formula skills or the theory are not thorough enough, and know where your bottleneck is before you can consciously solve it, that is, you should reflect on your knowledge system at any time.
Have the confidence to overcome difficulties, rather than blindly escape, or you will pull more and more.
There are many students who do well in math in junior high school. After entering high school, they felt mathematics.
When they do exercises or extracurricular exercises, they often feel at a loss and don't know where to start. So after a stage, their math scores are serious.
Phenomenon. What is the main reason for this phenomenon? According to my years of teaching practice, there are mainly the following reasons:
The reason for the textbook:
In textbooks, most knowledge points are close to the reality of students' daily life, while junior high school textbooks follow.
rise to
Law,
Relatively simple, the language is easy to understand, intuitive and interesting, the conclusion is easy to remember, and the test-taking effect is ideal. Therefore, students are generally easy to accept, understand and master. Relatively speaking, high school
Abstract and logical, the textbook narrative is more rigorous and standardized, and the knowledge is more difficult.
and
It has obvious improvement, many types of exercises, flexible problem-solving skills and relatively complicated calculation, which embodies the characteristics of "high starting point, great difficulty and large capacity". This change inevitably causes some students not to adapt to high school mathematics learning, which in turn affects the improvement of their grades.
Reasons for teaching methods: junior high school mathematics content is less, knowledge is not difficult, teaching requirements are low, and teaching progress is slow. For some key and difficult points, teachers can have enough time to explain them repeatedly and rehearse them many times to make up for the shortcomings. However, after entering senior high school, the content of mathematics textbooks is rich, the teaching requirements are constantly improved, and the teaching progress is accelerated accordingly. The key points and difficulties of knowledge can not be solved by repeated emphasis in junior high school. Moreover, high school teaching is often inspired and guided by setting guidance, asking questions, setting traps and setting changes, and then students think and answer by themselves, paying more attention to the process of knowledge generation and emphasizing the infiltration of students' thinking methods.
This makes some students who have just entered high school very uncomfortable.
It exists in class.
Can't keep up with the teacher's thinking, leading to
, affect the learning of mathematics.
Reasons for learning rules: In junior high school, some students are used to revolving around teachers, and their ability to think and summarize rules independently is poor. They are satisfied with the acceptance of knowledge and the lack of learning.
Mathematics learning in senior high school requires students to be diligent in thinking, good at summing up laws and mastering mathematics.
Do the same thing,
However, freshmen in senior high school often follow the learning methods of junior high school, and they have difficulties in learning, even the homework of the day is difficult to complete, not to mention self-digestion and self-adjustment such as review and summary.
Other reasons: students' emotions, interests, personality,
Advantages and disadvantages, learning purpose and
In a sense, how does it affect the mathematics learning of senior one students?
In view of the above reasons that affect mathematics learning, how should students make up for these deficiencies? From a height down.
Talking about several routine steps of learning;
Thoroughly understand what you have learned: high school mathematics is theoretical and abstract, which requires students to make great efforts to understand knowledge, not just to find out.
The essence of the concept, but also to understand the background of the concept and its connection with other concepts. For example, junior high school students can understand it.
I did this survey among freshmen in senior high school: Why?
Is there a root when △≥0? The correct answer rate is less than 15%. What does this mean? Student pair
This concept is not well understood and related knowledge is not connected.
Treat preview scientifically: for some parts
For students who are not ideal, I advocate previewing before class. The correct way is to imagine the content and structure of this lesson without opening the book, and then open the book. When you see that you want to define a concept, immediately cover the book and try to define it yourself; See the first statement of a theorem, then cover the book and guess his conclusion; The same is true when you see a formula. When you see an example, don't look at the solution first, do it on paper first, and then compare it with the solution in the book ... This preview is conducive to mastering knowledge and training thinking.
about
For students who are good at thinking and quick-thinking, I don't advocate preview before class, because they already know the content, conclusion, derivation process and solution of the example in class. Then, what can we talk about in class, such as "thinking ahead, really being the master of the class, and training thinking in the thinking movement?" This white color
I spent a long time developing myself in class.
Opportunity.
Improve the efficiency of class: during the study period of senior three, students' class time accounts for a large part. So the efficiency of class determines the learning effect. I think, to improve the efficiency of lectures, we should pay attention to the following aspects:
First of all, we should make material and ideological preparations before class to avoid losing books and other things in class; Don't do too intense physical exercise before class, so as not to be breathless and restless after class.
Second, class. What matters is not "listening" but "thinking". Listening is the premise, followed by positive thinking. We should devote ourselves to classroom learning, so that we can hear, see, touch, speak and reach.
Listen attentively to the teacher's lecture, how to lecture, how to analyze and summarize, and also listen to the students' questions and answers to see if they are enlightening.
Eye-catching: while listening to the class, read the textbooks and blackboard writing, watch the teacher's expressions, gestures and demonstration experiments, and accept the ideas that the teacher wants to express vividly and profoundly.
Heart orientation: think hard, follow the teacher's teaching ideas, and analyze how the teacher grasps the key points and solves problems.
Oral English: Under the guidance of the teacher, take the initiative to answer questions or participate in discussions.
Easy to grasp: draw the key points of the textbook on the basis of listening, watching, thinking and speaking, and write down the main points of the lecture and your own feelings.
Views. Will be the focus of the lecture,
Make a brief record for review, digestion and thinking.
In short, the "do-it-yourself" classroom listening is the most scientific.
Pay attention to review and summary;
1, review in time
On the second day after class, you must do a good job of reviewing that day.
The effective review method is not to read or take notes over and over again, but to review by remembering: first, put the books and notes together, recall what the teacher said in class, analyze the ideas and methods of the problem (or write them in the draft book while thinking), and try to think completely. Then, open the notes and books, compare and make up the ones that are not clearly remembered, thus consolidating the content of the class that day and checking the attendance of the day.
2. Do a good unit review.
After learning a unit, you should review it in stages. Review method is the same as timely review. We should review by recalling, and then compare with books and notes to improve the content. Then we should do a good job of unit plate.
3. Make a unit summary.
The unit summary shall include the following parts:
(1) This unit (seal)
;
(2) The basic ideas and methods of this chapter (which should be expressed in the form of typical cases);
(3) Self-experience: In this chapter, you should record the typical problems you did wrong, analyze their causes and correct answers, and record the most valuable thinking methods or examples in this chapter, as well as the problems you have not solved, so as to make up for them in the future.
Proper problem solving: Many students pin their hopes of improving their math scores on a large number of problem solving, which is inappropriate. In fact, to improve their math scores, it is not important to do more exercises, but to do them efficiently. The purpose of doing exercises is to check whether your knowledge and methods are well mastered. If you are not sure or even biased, the result of doing so many exercises will deepen your shortcomings. Therefore, it is necessary to do some exercises on the basis of accurately mastering the basic knowledge and methods. For intermediate questions, we need to pay attention to the benefits of doing the questions, that is, how much we get after doing the questions. This requires some "reflection" on the basic knowledge used in this question after doing the questions.
What is this? Why do you think so? Are there any other ideas and solutions?
And the solution, when solving other problems, have you used it? If you connect them, you will get more experience and lessons. More importantly, you will develop good thinking habits, which will be of great benefit to your future study. Of course, it is impossible to form skills without certain exercises (homework assigned by the teacher).
In addition, whether it is homework or exams, we should put accuracy first and general methods first, instead of blindly pursuing speed or skills, which is also an important aspect of learning mathematics well.
After-school self-study and research: The purpose of after-school self-study and research is to broaden knowledge, broaden horizons and further improve the ability to apply what they have learned to solve problems. The scope of self-study after class should not be too big, but should read some extracurricular reference books and
Do some fresh or difficult exercises. Self-study after class should be carried out in a planned and controlled way, rather than
Does not affect the study of other subjects. In the process of self-study after class, I found some novel and valuable exercises, and some good ones.
And the problem-solving methods should be written down for further study and mastery. Good foundation,
Strong students can choose one or two topics, conduct in-depth discussion and research, write research results into papers, and cultivate and exercise their thinking ability. The foundation is not very good.
The average student should always have a good foundation,
Strong students study and discuss some math problems together and learn from them.
Method.
Method is a necessary condition for learning mathematics well. In addition, remember two sentences. "For everything, only love is the best teacher", "Shushan has a diligent way,
With interest, methods, and diligence, I believe that every aspiring student will be able to learn high school mathematics well.
