Now that I am in my second year of high school, I don t have a good foundation, how can I learn chem

Let me tell you, the second year of high school, it doesn't matter if chemistry is not good in the first year of high school, the second year of high school is organic matter, the first year of high school is inorganic, the relationship between the relationship is very small, I only scored 27 points in the final exam of my first year of high school, the teacher is too that, I didn't learn at all, to the second year of high school, I changed to the strictest chemistry teacher in the school, although the start is not simple, as long as you start, soon, to the chemistry in the third year of high school in the science mock exam I used to take the chemistry test to the first in the paragraph, and, now I am a college graduate, to say, chemistry is really useful, My future is estimated to be in the development of chemistry, that is, the development of organic matter, and there is another sentence, the college entrance examination, I remember that my college entrance examination that year, there were not many inorganic topics.

I will send you a set of 2009 to 2010 high school freshman and sophomore chemistry ** class, except for not being able to communicate with the teacher, the rest is the same as the teacher's class, you can listen to it repeatedly, it will definitely help you improve your chemistry scores. Interested hi.

Chemistry should actually be divided into liberal arts, many things need to be memorized, like those within the concept, to know why, first of all, you should read the textbook "carefully" (details determine success or failure), and then do some basic questions to deepen your understanding, don't look at the master. Experiments are also a very important part, so be sure to listen to the teacher's lectures. Usually when doing questions, you need to accumulate more information, such as reasoning questions, often a chemical reaction is the key to answering the question.

In the third year of high school, the teacher will systematically review you, so you must listen carefully at that time. In fact, chemistry is the easiest of the science subjects, as long as you put your heart into it and add time accumulation, your grades will come up. Learning is a long-term accumulation process.

In addition, you should insist on exercising, habits affect your life, and you must "persevere".

The combination of elements must be familiar.

If you read the textbook thoroughly, you will definitely be able to learn it well.

Then you should pay attention to the efficiency of the class when you take a new class, I am also a sophomore in high school, and according to your current situation, I can only do this for the first time. The second is to understand the principles of knowledge you have learned before, at least it is not a problem to listen to the lectures, I also know that there is a lot of homework, and you have to put your good subjects first, because you will do it, and it will come quickly to make up for it in the future, and it will not delay you too much time, so that you will have time to make up for chemistry. Go for it!

I still remember when I was a sophomore in high school, chemistry was also a dead end!! But I changed the teacher and told me to start from books, so I read the books for two months, and I didn't start doing questions until two and a half months before the college entrance examination, and I still scored more than 90 points in the college entrance examination!! Read well!! Don't rush into the puzzle!

1 How to improve your sophomore chemistry scores1. Master the chemical equation

The most important thing in chemistry is chemical equations, there are many students who do not pay much attention to chemical equations when learning chemistry, in the chemistry exam, chemical equations appear the most, we must master the basic content of chemistry clearly when learning.

When memorizing chemical equations, we should practice trim more, which is also the easiest fraction for us to distance ourselves, do more training questions, and make some basic knowledge common.

2. Strive to have more questions in class

This can not only focus our attention, but also figure out what we have not understood well, which is very helpful for us, and the positive questions in class will also enhance our self-confidence, so that our chemistry grades can improve.

3. Pay attention to chemical experiments

In fact, the easiest way to memorize chemical equations is to understand that when we do chemical experiments, we can get the corresponding reactions by ourselves, and there are many students with good chemistry scores, and their chemical experiment operation ability is also very good, so we also need to pay attention when studying.

Fourth, we must not be "distracted" in class

When we study in class, we must not be distracted, try to listen to the teacher's explanation throughout the class, the content of the teacher in the class is very important, there are many times we do a lot of chemistry problems, it is better to listen to the teacher's content well, understand well, so that our grades can improve faster.

1.Before class, you should get into the habit of reading through what you are going to learn in this lesson. Read the textbook before class, mark the knowledge points that you will not know, review the knowledge points you have learned, and review the content of this lesson in your mind, so that you can effectively learn in an orderly manner according to the teacher's steps during class, and accept the knowledge imparted by the teacher to the greatest extent in a limited time.

2.Improve observation and hands-on skills. In each experimental process, we must concentrate on observing the steps and the final experimental phenomenon, not just a temporary novelty, and we don't know what is going on after reading it, and we will leave it behind after class.

Be clear about what you observe, what you have learned through the teacher's demonstration, and what it would be like to do it yourself.

3.Get to grips with a great way to take notes. We have to take the whole lesson with a serious attitude, and taking notes is a sign that we are serious and responsible.

In particular, you should concentrate on writing down the teacher's solution ideas for a problem and the key and difficult points marked by the teacher in the book, but don't lag behind the teacher's steps because of note-taking, it will be difficult to understand the content of the teacher's lecture if you can't keep up with the teacher's rhythm, and you should take notes step by step and method.

In order to take a good laboratory class, it is necessary to conduct a preview before the class and clarify the purpose, principle and operation steps of the experiment. When conducting experiments, do it yourself, try boldly, and strictly follow the experimental procedures in an orderly manner, chemistry is a course that we should operate with great seriousness and care.

Many high school students have a poor foundation in chemistry, which makes it more and more difficult to study chemistry in high school, and their grades are getting worse and worse. So, what to do if you have a poor foundation in high school chemistry? How do you learn chemistry in high school? Let's take a look with me!

1. For high school students who have a poor foundation in chemistry, it is first necessary to make it clear that no matter what chemical reaction it is, it must be considered from the perspective of the periodic table. The reaction principle of chemistry and the valency of the state of matter are basically in line with the distribution law of the periodic table. Therefore, high school students can prepare a notebook for learning chemistry and record some irregularities, including all the special colors, precipitation, valence and other values of the reaction of the elements or reactions.

2. Secondly, many high school students who do not have a good foundation in chemistry do not remember the knowledge points of special elements and equations very clearly. But in fact, these are very important, such as the reaction can produce special gases, precipitates or color elements are the key points of high school chemistry test and problem solving.

3. Compared with other subjects, high school chemistry knowledge and test points are really not very much, so it is feasible to work hard and improve your grades in the short term. But remember not to wait until before the exam to surprise again, so that even if you are smart, it is useless, and the premise of improving your score in the short term is that you have the foundation and preparation. Therefore, if high school students want to learn chemistry well, they must lay a good foundation, remember, start now and persevere, and success will be yours.

4. The last and most important point for high school students to learn chemistry well is to listen carefully in class. Only by concentrating and taking the initiative to learn can you become interested in chemistry and eventually learn chemistry well. When the teacher imparts new knowledge, high school students should think about how the teacher analyzes the problem and be able to follow the teacher's train of thought.

When the teacher summarizes the content of this lesson, it is necessary to pay attention to the learning focus of this lesson.

There are three main aspects of learning chemistry well: 1. Insist on pre-class preparation and active learning, 2. Pay attention to in-class learning and improve classroom efficiency, 3. Complete homework independently and review in time.

Only with efficient learning methods can you quickly grasp the important and difficult points of knowledge. An effective way to read books is to master the method according to the rules, and once you get the grades, you will be more engaged.

1. Insist on pre-class preparation and active learning: It is important to read a new lesson, it means that you can take a step forward to help us understand the basic content of the textbook, find out the difficult points, and use it as a knowledge preparation for learning the new lesson.

2. Pay attention to in-class learning and improve classroom efficiency: listen carefully to classes; Take good notes, which can help us to stay on top of things when reviewing later.

3. Complete the homework independently and review it in time: The homework should be completed independently, even if you can't, you have to check the information by yourself, because this is equivalent to exercising you and consolidating the knowledge learned in this section. Finally, you must memorize the formula.
