I can t understand chemistry all the time, what should I do?

Hello; Here's an article for you to learn about chemistry. --Chemistry, don't take your own poor subject as a subject you worry about, because chemistry is not very difficult to learn, since it is because of the weak foundation, do it like this:

1。If possible, you can ask the laboratory teacher to prepare reagents for you, and you can review the properties of chemicals in the third year of junior high school through experiments, which is the easiest way to memorize the properties, and if the conditions do not allow, you can only use rote memorization. In short, the foundation of the third year of junior high school is the most important.

2。The knowledge in the first chapter of the first year of high school runs through high school chemistry, so, be sure...

3。The general method of learning science is the tactic of the sea of questions, although for a long time, many people do not advocate it, but it is the only tried and tested method that I have used until now, you can experience unlimited knowledge by doing more questions, only by doing questions can you learn your own understanding of subject knowledge, in order to have your unique insights, after you do a lot, you will find that you feel more and more when you do the questions, but the foundation is the most important.

4。It is more useful to go from the sidelines: the educational method of coping with the college entrance examination is now adopted by teachers.

We must not only use the knowledge in books to deal with the college entrance examination, but also expand our knowledge, and know more about chemistry, only the benefits are not harmful, so we must understand more knowledge beyond books. There is also an easy way to do the problem is what I call the side door, do the problem quickly, in the volume of matter in the chapter of the calculation problem is best not to memorize the formula, the formula will always forget, but once the idea of doing the problem is mastered, it is difficult to forget, you better use the meaning of the operation to do the problem, or according to the unit to do the problem, what is the unit of the required quantity, what is the unit of the known quantity, through the operation between the unit, you can get the relationship between the known quantity and the unknown quantity, I will not list many such examples, you yourself encountered the problem of that chapter, You can understand it by experiencing it yourself.

5。Attitude is everything: whether you really take chemistry learning to heart is the key to determining whether you can learn it well, you just need to pay attention to it, as I said earlier, you don't worry too much, you just need to give it a proportional time to study in proportion to the score of the college entrance examination.

If you are too worried, you will fall behind in other classes, and in the end it will be a failure, and in the college entrance examination, which one of you still has the potential to be a body, you will study whichever one. A score of 100 in chemistry is remarkable. The college entrance examination focuses on the examination of comprehensive ability, and no one can be left behind.

Finally, let's wish each other well! Come on! We will succeed through hard work! In the future, everyone will help each other a lot, naruto+sasuke from the person who loves to ask knowledge)

Chemistry is actually very easy to learn, I don't know if it's high school or junior high school, anyway, I personally think that it depends on whether you like it or not, if you don't like it, you have to let yourself like it, first of all, don't feel afraid, read more questions, remember to write more basic knowledge and equations, and slowly lay a good foundation for yourself, you will feel that it is not difficult.

Is it junior high or high school? The content of junior high school is mainly memorized, and if you don't understand it, you can study it on your own, and it's basically not a big problem to search for some chapters and knowledge points summarized by predecessors on the Internet to familiarize yourself with them. If you want to be a little more difficult in high school, you need to memorize it and use it flexibly.

It's like this at the beginning, don't give up, maybe you don't understand it very well now, and when you look back, it will suddenly become clear. I studied chemistry in college, and now I look back at the chemistry that confused me in high school because I was rare and weird, and it wasn't even worth mentioning, so please stick to it.

If you think about it this way, high school knowledge must be easier than college, and you have to be confident in yourself.

Listen carefully in class and take notes. Memorize the test points, such as formulas, or some hidden formulas.

Make a list of knowledge frameworks, write what the total knowledge points are first, then write out the branches, and then infinitely subdivide them to the most basic points, and then you can know which point will not be when you summarize. Won't be on the phone, or ask the teacher.

It's like playing a game point skill tree, if the most basic ones are not unlocked, how to unlock advanced skills.

If you are not familiar with the content of the column knowledge framework, you should write the content in detail.

Then, when reviewing or the content is more familiar, you can omit the content of the branch that is ripe.

The former can be studied in detail and systematically. The latter can increase efficiency and avoid inefficient repetition.

Wait until you can list the complete knowledge framework. Explain that you have mastered the general situation, go to the questions to verify your results.

When I encounter a question that I can't know, I look at the answer, and then understand, why I do it, is there any knowledge point in this question that I don't know, and then can I understand this knowledge point, can't it. Once you understand it, make another frame, or add it to the notes you wrote before.

Will I do this kind of question again, you can try to change the digital content of the question yourself and see if you can make it. This is very efficient and can quickly grasp the question type.

It's important to take time out to preview and read your textbooks and resource books first. You must first have a general understanding of what the teacher is going to say. There is also persistence, if your foundation is relatively poor, you must persevere, it is impossible for you to do this for the first time to have obvious results, and you must insist on pre-study every day.

It is recommended that you review the previous content more, so that you also know that the teacher's lecture involves the previous content.

To listen carefully, you try to concentrate on following the teacher's thinking, don't always think about taking notes, you just need to remember a little bit of what you want, or what you don't have in your reference book, the key to listening to the class is the word "listening".

Preview, review, correct mistakes, consolidate, improve, ask questions, think more, think well.

Ask teachers and classmates for advice, understand the questions as soon as possible, preview the content of the next class, write down the questions you don't understand, and listen carefully during class.

Start the analysis from NACL, go from shallow to deep, read books by yourself, and then connect with alkali metals, halogen elements, and then expand to other group elements, so that you can have a good understanding of the periodic table of chemical elements, so that chemistry is almost learned. As for dissolution, calculation, etc., then it is more mathematical, and there are more problems.

In short, there are still a lot of things to remember in chemistry, so you must be organized, pay attention to the personality of each thing, and understand the reasons.

Because school has just started.

Just hold on.

Do a little more chemistry questions. Remember to prepare.

Let me tell you about my own personal experience: When I was a freshman, I was "unlucky" to take the make-up exam for my high math (below) But "fortunately", my high math (I) was learned last semester, and I didn't study much in the next semester.

The make-up exam will be held on Monday morning, so I locked myself in the house on the weekend (there was no weekend weekend at that time, only one day off on Sunday), from Saturday after dinner, until 12 o'clock in the middle of the night, I started reading from the first page of the book, understood every example question (yes, I can't lie to myself at this time), and by 12 o'clock on Sunday night, I went through it all, and finally the make-up exam score: 72 points.

I want to tell you a few things about this experience:

1. If it weren't for my foundation in advanced mathematics (above), I wouldn't have been able to read this weekend (one day and two nights) just - this shows that the foundation is very important;

2. But it only took me such a short time to review and I was able to pass the make-up exam - this shows that if you really want to make up for science, it is easy to make it back. However, liberal arts need to rely more on the usual accumulation, if you have to take the English retest, you may not be able to get much better than the main exam score if you are given three months......

So, don't worry if you don't understand what you're teaching now, spend your energy to understand the previous things first, and gradually chase them, and ask the teacher and classmates if you don't understand in the process of chasing - even if you can't catch up with 20% of them because of time in the end, but you at least have the ability to score 80 points, aren't you?

To be honest, Takayama is now this time. If the basics are not good yet, especially the chemical aspect. Lots of reaction equations. If you haven't memorized the principle of machine translation, it is more difficult to tutor.

1. Chemistry mainly first understands the principles, then combines experimental phenomena and chemical equations, diligent memorization, and then combines some typical exercises to strengthen understanding and memory, and then pays attention to the comparison, induction and sorting of knowledge points. In fact, the questions are quite common, grasp the equations and various calculation formulas, and memorize the properties of various substances.

2. Another key point in learning chemistry is efficiency, and only efficient learning can get twice the result with half the effort. I practice the "Elite Special Whole Brain Speed Reading and Memory Software" to stimulate the potential of the brain and improve the efficiency of learning and revision. Speed reading memory is an efficient learning and review method, and its training principle is to activate our "brain and eye" potential, cultivate us to directly convert the text symbols perceived by the visual organ into meaning, eliminate the potential pronunciation phenomenon in the mind, and cross the process from sound to understanding the meaning, forming an eye-brain direct reflection reading mode, and realizing the leap of reading speed, overall perception, comprehension and memory, and concentration.

3. Preview before class. The day before class, be sure to take time to consciously preview what the teacher will talk about the next day. Learn to study first and then listen to the lectures.

4. Listen to every class. Listening to lectures is the core part of the learning process, and it is the main way to learn and master knowledge. Whether you can master the knowledge learned well in the classroom is the key to determining the learning effect.

If you can basically master the basic knowledge and skills you have learned in class, you will not have difficulty reviewing and doing homework after class.

5. Take good notes. To learn chemistry well, note-taking is also an important part. In addition to focusing one's attention and improving the efficiency of listening to lectures, note-taking is also a great help for post-class review.

So, learn to take notes and develop a good habit of taking notes. Therefore, while listening carefully, you should also take good notes.

6. Careful observation and hands-on experiments. Through demonstrations and student experiments, learning to observe the operation and phenomenon of the teacher's demonstration experiments, doing student experiments independently, and taking good laboratory classes are the foundation for learning chemistry well.
