How to do a good job in the first round of chemistry review in the third year of high school

1. Summarize the chemical reaction equations for each content module.

2. Refine the concept of each key element.

3. Summarize the key points and precautions of each experiment.

4. According to the periodic table of chemical elements, the corresponding chemical properties and physical properties of each group of elements are summarized in detail.

5. Construct a knowledge network diagram of chemistry discipline.

The first round is mainly to lay a solid foundation, turn over the textbook more, and don't let go of even the small print part. To summarize the equations for the chemical reactions of the individual units.

In particular, summarize the key points and precautions of each experimental content, and then summarize the corresponding chemical properties and physical properties of each group of elements according to the periodic table of chemical elements, and finally draw a table.

In the first round, I went to buy some basic test papers to do and consolidate the basic knowledge in the textbook. After I finish it, I will buy some intensive training questions to do, and after I finish it, this semester is basically over, and I will be practicing the science comprehensive test paper next semester to ensure that you get a good score in the college entrance examination! I wish you success in advance.

High school chemistry is a simple and complex subject. The simplicity is because it does not have more difficult problems like physics and mathematics, and the complexity lies in the fact that it has a lot of knowledge points and is very messy, and it is not easy for students to sort it out by themselves. In addition, chemistry itself has the characteristics of liberal arts in science, so the following points should be paid attention to when reviewing in a round:

1. Basic knowledge part (quantity of substances, ionic reactions and redox reactions): master the basic concepts, and then be familiar with the basic concepts and formulas on the basis of the college entrance examination questions in the last five years, analyze the types of exam questions for each knowledge point, and overcome them one by one.

2. Elements and their compounds (seven topics on metals and non-metals): firstly, it is necessary to grasp the physical properties of substances (such as color, state, density, etc.), and secondly, to master the chemical properties of these substances, and to master the chemical reaction equations through the understanding of chemical properties.

3. Key and difficult parts (heat of reaction, electrochemistry, chemical equilibrium and salt hydrolysis): This part of the knowledge is the difficult point of high school chemistry, but it is relatively easy to get points if you can find out the rules and skills of solving problems through question types in the process of learning.

4. Organic Chemistry: Learning methods are the same as elements.

Review thoroughly and keep up with the teacher.

6. Refer to some excellent chemical materials or famous books.

The foundation of chemistry is very poor, how should I review you this summer, can I say it concretely, what you said is too abstract, I can't understand it.

Dear, how many years are you reading now?

High school. Do you know what the foundation of chemistry is?

I don't know the specifics, in short, I don't know, and the child himself doesn't know which piece he can't do, because there are too many of them, what should I do in this situation.

Are you planning to enrol your child in a tutoring class or homeschool?

You can learn some by yourself at home, or you can find a tutor, because she can't keep up with the large class of the tutorial class, and she will score 30 points in the second semester of the second semester of high school.

In this case, the foundation is too poor, pro.

First of all, it is necessary to understand why the child's chemistry performance is not good, whether it is because he does not have a deep grasp of chemical concepts, or whether he is not easy to understand the basic ideas of chemistry, or whether he is not familiar with the type of chemical reaction, and find out the specific reasons by analyzing the problem.

If the child has no idea where to start, it is recommended that the child first lay a solid foundation and review all the basic concepts of chemistry one by one, such as the electronic structure, the composition of matter, chemical reactions, solubility laws, etc.

There is also a more effective way to do the wrong questions, the usual exam before the test papers, do the practice questions orange regret eggplant, all find out, do it repeatedly, train, the foundation is mastered, the question type is roughly like that, repeatedly do the wrong questions can deepen the understanding and analysis of the circle inspection questions.

Start with the first chapter, finish the first chapter, and do the wrong thing again.

Yes, dear, the front is the basics, first memorize the basics before doing the questions.

Don't ask for fast, don't be afraid of slow, but be sure to master it well in the following.

The first round is probably the first semester of the third year of high school, read all the books for three years and add after-class exercises, lay a solid foundation, the most important thing is to figure out the basic concepts, memorize the formulas, and memorize the special reaction equations and experimental phenomena, and read the textbooks thoroughly. This is the foundation, because 70 out of 100 points are foundational questions. If the foundation is unstable, just wait to cry.

The second round is the first two or three months of the second semester of the third year of high school, and there are a lot of mock exams for the college entrance examination, and there are at least one test of all subjects every week. We were back then. Constantly doing questions, mastering problem solving, adjusting mentality, and skills are the most important, and at this time it is to strive for 20 points out of 100.

Every exam is an accumulation of experience points, constantly summarize and reflect on their own shortcomings, there are unclear chapters and parts to return to the textbook to figure out, difficult problems must at least make an idea, calculation mistakes, write the wrong equation, a certain algebra such low-level mistakes do not make.

The third round of review is actually only a month, and at this time, all the high school joint examinations in the province and the like are several times in guessing the questions Which direction to go out of the paper What can be done is to be steady and ruthless. Because these exams are equivalent to the final form, the last 10 points out of 100 are depending on your mentality. Some people are usually very good, but they are nervous about the exam and make mistakes, which is a poor psychological quality.

The average score of these exams is probably less than 10% of the breakup error at the end of your college entrance examination.

Endorse and memorize notes, do exercises, and summarize mistakes.

Based on the syllabus and examination instructions, based on the textbook, carefully analyze the academic situation and the questions of the college entrance examination over the years, and on this basis, earnestly grasp the review stages such as "basic review - special review - simulation training", so as to receive better review results and improve students' chemistry scores.

Make reasonable use of your time, and don't be arrogant and impatient to eat your textbooks thoroughly, otherwise, it will be impossible to improve later. Do a good job in each question, take good notes, summarize the problem, even if it is a small problem that cannot be solved, you must ask the teacher and classmates, and learn to draw inferences. Memorization involves every point of our knowledge, and finds out the difficulties, doubts, and key points.

When you grasp your foundation, buy a five-year college entrance examination three-year simulation to strengthen your knowledge points, and on the premise of a solid foundation, you can do the first document of the college entrance examination, or 38 sets of Tianli to improve your overall knowledge points. Of course, you can't blindly study hard, you have to give yourself a study plan, persevere, and calculate how much you can improve according to your daily progress.

Secondly, a copy of the study plan is attached:

1: Make your own study plan in advance.

2: Review, preview, summarize, and take notes in advance.

3: Familiar with every knowledge point we are involved in, ask if you don't understand, do more, practice more.

4: Do a good job in each question, summarize it, and learn to draw inferences.

5: Change from passive to active follow-up every time.

If you don't understand something, even if it's very simple, you have to understand it, and you must not be embarrassed to ask teachers or classmates because it's simple.

There's nothing to say, practice more questions, especially inference questions, and of course, the basic skills are not solid in the tasks you come down to, such as the properties of special substances.

I mainly read textbooks, and I don't need to read other materials.

The organic part is divided into six topics for review: the first topic is the basic concept of organic, and the basic concept first has an understanding of the concept of organic matter, that is, what is organic matter, and some special terms in organic matter, such as systematics. The basic concept of organism is a very theoretical part of organic chemistry, which has been reflected in the college entrance examination over the years.

There are specific methods for reviewing isomers, and students should be very clear in their hearts. For example, the isomerism of carbon chains and the position isomerism of functional groups should be paid attention to symmetry and relativity. The main idea is like this, of course, there may be some differences in a specific substance, and students need to continue to explore in their usual study and problem-solving.

The naming of the basic concept of organic mainly grasps the nomenclature of alkanes, and it can be extended to other names; The second part, the spatial configuration of organic molecules, is for you to determine whether the carbon atoms of slightly more complex molecules are colinear or coplanar, in fact, they are all composed of four parts, such as methane, ethylene, acetylene, and benzene. Combine them in a certain way to form a more complex molecule. When students are judging, each basic stage maintains the original configuration, but when the basic structural unit is combined with each unit, usually the single key can be rotated, the double key and the triple key can not be rotated, and the students can judge how to answer according to the basis; The third part, Types of Organic Reactions, is the core of organic chemistry because it mainly introduces the typical chemical properties of each functional group.

There are two ways to review, one is vertical review and the other is horizontal review. The longitudinal review is in the order of each functional group, and the nature of each functional group in the mind must be particularly clear, which is a longitudinal review; You can also review horizontally the various types of reactions we encounter in middle school, such as substitution reactions, addition reactions, oxidation reactions, which substances can be substituted, and what substances are substituted, and under what conditions substitution reactions occur, mainly talking about the types of organic reactions. This piece of content must be particularly profound and thorough, and students must be particularly proficient.

Because our current investigation of organic chemistry is mainly in the latter major topics, one of which is the investigation of organic chemistry, which examines the evolution of various functional groups; In the fourth part, organic synthesis inference, some methods and ideas for solving inference problems are summarized according to the previous college entrance examination questions. In the fifth part, organic chemistry experiments, including property testing experiments, synthesis experiments, etc., we provide students with common questions and related principles related to testing, preparation, separation, and purification. Part VI, Organic Computing. Organic Chemistry is based on these six topics for students to review, if these six topics are all clear, organic chemistry should be no problem in this unit part.

It is important to remember the chemical reactions involved in organic chemistry, such as hydroxyl groups, carboxyl groups, etc., and focus on distinguishing the chemical reactions of these representative substances.

It's good to figure out the basic structure, understand their nature, etc., for organic, it's good to read books, don't get too entangled in too many questions, organic questions as long as you master the basics, and what innovative questions other teachers say are very simple. The main thing is to sort out each structure well, such as carboxyl groups, hydroxyl groups, halogen atoms, ·· Put their nature, structure, ·· and other related knowledge points are listed in a separate book. After that, you have to review for the second round!!

As long as you look at it, you basically know a lot about organic, and you can't lose a single point in --- college entrance examination.

The main thing is to read more books and figure out the properties and characteristics of each type of organic matter. The most important thing in a round of revision is to read more books and do exercises at the same time. This will be very, very helpful for your later second round of revision! Hope you can adopt it!

1. Efficient review, we must learn to sort out our own learning situation, based on textbooks, combined with our own notes, test papers, weak links, existing problems, etc., reasonably allocate time, and target and specific to overcome and implement little by little. If you don't grasp the content well, spend more time, and when you review, you should be systematic, don't go east and west, and end up reviewing nothing.

2. You can learn to master the ability of speed reading and memorization, and improve the efficiency of learning and review. Speed reading and memorization is an efficient learning and review method, and its training principle is to activate the potential of "brain and eye" and cultivate the formation of eye-brain direct reflection reading and learning mode. For the practice of speed reading memory, see "Elite Special Whole Brain Speed Reading Memory Training", practice with software, more than an hour a day, a month's time, you can double the reading speed, memory, comprehension, etc., and finally improve the efficiency of learning and review, and achieve good results.

If your reading and learning efficiency is low, you can practice it well.

3. Learn to integrate knowledge points. Classify the information you need to learn and the knowledge you need to master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review, and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system.

This promotes understanding and strengthens memory.

4. When doing problems, you should learn to reflect, classify, and sort out the corresponding solution ideas. When you encounter the wrong questions (carelessly do it wrong, you can't do it), it is best to collect these wrong questions, and each subject has an independent set of mistakes (the set of mistakes should be classified), and when we review before the exam, they are the key review objects to ensure that there are no more mistakes and points on the same questions.
