How to learn biology and physics? Thank you!

Interest is the biggest teacher, is the best motivation for learning Then there is attitude, a positive and enthusiastic attitude to invest in cultivating your interest, with a knowledge-seeking attitude towards biology and physics, learn more, ask more questions, do more exercises, and you can slowly learn biology and physics well

Learning physics is very process-oriented, a process of cognition, understanding, and application.

1.Cognition: Use the things or phenomena around you or even some examples narrated by the teacher to help yourself fully understand it and become interested in it.

2.Comprehension: Use understanding to memorize formulas, theorems, experiments, etc. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way: a vacuum is really empty, there is nothing.

3.Application: One is to cope with the exam, and the other is to explain some physical phenomena around you.

So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!! In fact, psychological suggestion is very useful!

However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it.

Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes. Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end.

Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong. How is the correct answer calculated?

Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well.

This depends on myself, my experience is that I should have a set of learning methods, usually for the textbook just to know more, to know the knowledge of the book well, in addition to think more, communicate with classmates, thinking is the most important, physics and chemistry are more closely related to life, so to a certain extent, to a certain extent, to connect with life experience. When I was in high school, I didn't like to listen to the teacher's lectures, I was self-taught, I usually thought a little more, and when I got to the college entrance examination, I took the A+ and A, of course, I had to be conscious.

...The most basic thing about materialization is high math and calculus ability, and then there are concepts, formula memorization and appropriate exercises (phase diagrams are a troublesome thing), mainly to understand the connotation and find the deviation of your own understanding.

Neither do I, I don't know anything about it.

Hello: If you want to learn physical chemistry well, in addition to memorizing the basic knowledge in books, you need to do questions or do questions. Only when you see more types of questions can you learn physical chemistry well.

How to do it, I think it's a little difficult to explain it to you clearly in this short sentence. I can provide you with some information if you need it. Hehe.

Biology learning is actually not difficult, don't be intimidated by the fact that there are many things and more knowledge.

According to the characteristics of biological science, the following points should be done to learn high school biology courses well:

1. Learning biological knowledge should focus on understanding and thinking diligently.

The basic concepts, principles and laws of biology are summarized and summarized on the basis of a large number of studies, with strict logic, and there is also a close connection between the contents of each chapter in the textbook.

2. It is necessary to pay attention to understanding the process of scientific research and learning the methods of scientific research.

The content of biological science includes not only a large amount of scientific knowledge, but also the process and methods of scientific research. Therefore, we should not only pay attention to the learning of biological knowledge, but also pay attention to the process of biological science research and understand the research methods of biological sciences.

3. Biology is an experimental science.

Without observation and experimentation, biology would not have been able to achieve such brilliant achievements. In the same way, if you don't pay attention to observation and experimentation, you can't really learn biology well. In daily life, we should also pay attention to the observation of life phenomena and cultivate our own observation skills.

4. It is necessary to attach importance to the integration of theory with practice and apply what we have learned.

Biology is a science that is very closely related to production and life. When we learn biological knowledge, we should pay attention to understanding the interrelationship between science and technology and society (STS), understand the social value of the knowledge we have learned, and use the biological knowledge we have learned to explain some phenomena and solve some problems.

If you think about it diligently, you may not be able to read the textbook, and provide a way to provide a way to hold a skeptical attitude towards the textbook, and repeatedly ask questions about every conclusion in the book to see if you really believe it, which not only consolidates the knowledge of the textbook, but also improves the interest in learning.

The speed of getting the moral bit by bit Biology I can't learn well, maybe I'm intimidated.

I think the first thing is to maintain a good mindset and believe that you can do biology well.

The second is to learn, that is, to accumulate, that is, to digest. Biology, this subject is not difficult, as long as you can listen carefully in class, digest it carefully after class, and ask the teacher in time if you don't understand.

Biology is ultimately tested for experiments, so the laboratory class should be taken seriously, practiced, paid attention to observation and recording, and unfamiliar experiments should be repeated several times until they are proficient.

If you do these three steps, then there should be no problem with the creature.

These subjects are basically memorized tests, so after each lesson, you must consolidate the familiar reading and memorization in time. In addition, according to my experience, in addition to memorization, it is very important to master the classroom when studying politics. Although most of the multiple-choice questions in politics are written points that are required to be memorized in textbooks, there are also analytical questions, material analysis and explanation questions, and sometimes practical questions to formulate activity plans.

This kind of topic requires the ability to understand it on a daily basis, but of course it can be cultivated slowly. It is also necessary to master problem-solving skills, such as what the material says about what it tells you, and analyze it from both positive and negative sides. Analytical questions are usually judged first, then analyzed, and the analysis process should be centered"What, why, how"Write and finally point out your point again.

In fact, if you want to learn anything, you should be interested in it first, (this is the premise) only if you are interested in them will learn it. And then exchange hard work for fruit (this is the key) There is no free lunch in the world, even if a person with great talent does not study hard, the final result will be no different from ordinary people, and even catch up with ordinary people. If these two things are done well, there is nothing to fear.

When I was in my first year of junior high school, these three subjects also gave me a headache, but I finally beat them. That's how I beat them.

I always think, can't I do what others can do? It turns out I could.

You have to believe in yourself, too!

In fact, I had similar confusion in the past. But now there are a few good ways! But multi-pronged!

First of all, doing the question is a must! But to know what it is, but also to know why! Otherwise, you're just wasting your time!

Secondly, pay attention to the lectures! This is an inevitable requirement for learning any subject well! Third, you should always ask the teacher, the teacher can accurately grasp the main points of the question, and asking the teacher a question is better than pondering 10 questions by yourself!

Fourth, pay attention to the usual accumulation, and don't just focus on the textbook! The high school geography exam is not only a textbook knowledge, it is very comprehensive, and you can watch more programs about geography on TV at ordinary times, which is the process of accumulation, and you can also look at more maps! That's all a great way to do it!

Follow these methods and I'm sure you'll reap the rewards! That's how I progressed! I'm sure you can!

Do more questions It is recommended that you use Wang Houxiong's textbook to fully interpret it.

1) Pre-class study. The day before class, take a look at the content that the teacher is going to talk about the next day, find out the difficult points, the teacher will listen carefully when he talks about the difficult points, when the teacher talks about the content that you thought you understood, if it is the same as what you originally understood, you will deepen the image, if the teacher talks differently from your original understanding, you can not only find your own problems, but also leave a deeper memory.

2) Keep up with the teacher's train of thought in class. You think what the teacher says, and you think as you listen. If you don't understand the questions, or you forget the math formulas and physical formulas and concepts used by the teacher, and you can't keep up with the teacher's train of thought, don't keep thinking about these questions, just write down the questions quickly, so as not to affect the following lectures.

Ask the teacher or discuss it with your classmates after class.

3) Review after class. Find out what problems the teacher talked about, which of these knowledge points are causal relationships, which are progressive relationships, and which are juxtaposition relationships. Do the example problems that the teacher has taught and the example problems that are in the book but not taught by the teacher.

That's why I chose these examples from so many questions because these questions are very important, and if you understand them, you may not really understand them.

4) Clarify the connotation. Of course, it is necessary to be clear about the physical quantities represented by the symbols in the formula, but it is also necessary to understand the concepts and the physical meaning of the formula. For example, acceleration is a physical quantity that represents the magnitude and direction of velocity (this is the physical meaning of acceleration), and the definition of acceleration is a way to express its physical meaning.

A physical quantity can have different definitions, for example, there are three definitions of magnetic induction intensity (only one is learned in high school), but the physical meaning is the same. Generally, the skills of physics problems are not as good as those of mathematics problems, and there are not as many things to remember in physics as in chemistry courses, but there are more difficult things to understand in physics than in these two courses, and it will be difficult to understand the connotation of physical concepts, physical laws, theorems and physical formulas. You can't learn physics without memorizing, but you can't learn it by rote memorization.

It is also necessary to clarify the scope of application of physical laws, the possible relationships between physical laws, and the problems to be paid attention to when using this formula to analyze and deal with problems. For example, f in the momentum theorem is the resultant external force. Another example is that there are generally three ways to solve mechanics problems:

Newton's laws of motion, the theorem of momentum and the law of equilibrium of momentum, functional relations. In order to figure out which method to use in those situations, in addition to a deep understanding of the physical laws involved in different methods, it is also necessary to use three methods to solve the same problem, that is, multiple solutions to one problem.

5) Complete homework independently. It's normal that you can't solve some questions, so when you can't solve them, you can look at the textbooks and class notes, and if you don't know how to do it, you can ask your classmates and even take a look at your classmates' homework, and do it yourself, don't copy it. There are not many questions to do, and to do a question is to really understand the question, especially the typical questions of the same type of question that do not prevent hunger.

When solving problems, it is necessary to pay attention to the analysis of physical processes, establish the wheel of the diagram, and have a clear idea.

6) Do a good job of summarizing the unit and systematize the knowledge.
