How to do a good job in the connection of middle and high school chemistry teaching

It depends on whether your teacher has infiltrated high school knowledge when teaching junior high school chemistry.

How to learn chemistry well in high school.

Chemistry is a fascinating subject. However, due to the characteristics of high school chemistry as "complicated, difficult, and chaotic", many students find it difficult to learn high school chemistry. So how can you learn chemistry in high school?

1. Listen carefully and take good notes.

Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process.

Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review.

2. Review in a timely manner.

Revision is not just a simple review of knowledge, but considering the interconnection of old and new knowledge in one's own brain, and reorganizing it to form a new body of knowledge. Therefore, after class, it is necessary to review the content of the lecture in a timely manner, and do a good job of sorting out and summarizing the knowledge, so as to make the knowledge integrate and avoid the phenomenon of more and more chaos in learning. For example, if you learn about the bleaching properties of SO2 and chlorine water, you can compare them to find out the differences.

3. Learn to memorize.

Since there are many chemical knowledge points to memorize, it is difficult to memorize them if you rely on rote memorization, so you should learn to memorize them skillfully. The commonly used memorization methods in chemistry are: comparative method (often used for knowledge that is easily confused and interferes with each other.

The four similar concepts of isotope, allotrope, homologue, and isomer can be deepened and remembered through comparison. ), induction, song recipe memory, comprehension memory, and experimental memory.

Fourth, practice diligently. Practice is an important way to understand, digest, and consolidate classroom knowledge. However, the practice should be targeted, not a sea of tactics, and should be aimed at mastering the basic methods and the rules of problem solving. In the process of problem solving, it is necessary to pay attention to multiple solutions and inductive summarization of one problem, so as to achieve the effect of doing one problem and one category.

For example, the techniques commonly used in chemical calculation include: conservation method, relational method, extreme value method, average value method, estimation method, difference method, etc.

5. Prepare a "mistake book".

The purpose of the questions is to develop abilities and find effective ways to find your weaknesses and deficiencies. Therefore, mistakes should be corrected and recorded. When recording, you should analyze the reasons for the error and the correct solution idea in detail, and do not simply write an answer.

At the same time, it is important to go through the review frequently so that you can avoid similar mistakes in the future.

6. Pay attention to chemical experiments.

Chemistry experiments can not only cultivate students' observation, thinking, hands-on and other abilities, but also deepen their knowledge and understanding of related knowledge, so we must pay attention to chemical experiments. When doing experiments, we should ask a few more whys, think about how to do it, why we do it, and what else can be done, so as to achieve the purpose of "knowing what it is and why it is true".

In addition, in order to study chemistry well, we should pay more attention to social hot issues and life problems related to chemistry, and be good at combining book knowledge with practice.

In short, as long as the learning method is correct, I believe that students will easily learn chemistry well.

1.For high school chemistry, it's the same if you don't study in junior high school. But first, elements 1-18 you must know. Know very well.

2.Then if you have time, if you are ready to take science. You can memorize the periodic table.

Column by column. For example, the first column. Lithium, sodium, potassium, rubidium, cesium, francium.

Second column. Beryllium, magnesium, calcium, strontium, barium, radium. It's easy to remember.

Of course, as long as the backsliding clan is on. It's okay if you don't carry it.

3.If you have time, you can do a few more chemistry calculations. It's OK in the third year of junior high school, and it's good to take out what you didn't need before. In this way, you can not only review some basic equations, but also exercise your problem-solving ability.

I remember when I entered the first year of high school, we didn't take a new class right away, there was a month-long bridging class, and at that time, chemistry was specifically about chemical calculations, and the difficulty of chemical calculations suddenly increased a lot (I was dizzy and almost gave up chemistry as soon as I entered it). But then I taught a new class, and it was much better.

4.Preview the new lesson. It doesn't matter if you can't read it. It's just to make yourself a little bit of a chemical vibe. Don't give yourself the illusion that you haven't studied chemistry.

The connection between high school and junior high school is not very large, and the more important ones are the symbols and names of elements, the valency of common elements and the reaction between the three types of acids and alkalis.

Back the symbols of the first 20 chemical elements, relative atomic mass, common element valence, common acids and alkalis, the use of chemical equipment, etc., chemistry is to remember less and not more, remember special, do more questions, as long as you listen to the class and do the questions, the high score is no problem, steady learning, invincible!

It's okay, compared to high school chemistry, there are too few things to learn in junior high school chemistry, and if you feel that you haven't learned chemistry well in junior high school, then you have to study chemistry class well in your freshman year of high school, and if you learn it well, the lack of junior high school will not exist.

I personally felt that chemistry was not good, but junior high school chemistry was only learned in the third year of junior high school, you can follow the teacher's pace as soon as you enter high school, and use your spare time to quickly review junior high school chemistry again, you will feel that there is not much content, rest assured, it will be no problem, come on!

It's not that difficult, don't worry! In fact, if junior high school and high school are connected, it is equations and reaction phenomena of various common substances. Everything else is very simple As long as you have the heart to study and listen well in high school, it shouldn't be a big problem. Have confidence and remember!!

Equations, pay attention to conditions, gas symbols and whatever. There is also the phenomenon of reactions.

I didn't actually learn anything about chemistry in junior high school, by the way, you can flip through more chemistry books if you have nothing to do, it's beneficial.

Grasp the key points, do more questions, and find the center.

Chemistry is not like mathematics, there are different chapters, different contents, and some contents are not directly related to each other; Chemistry itself is a whole subject, and the chemistry studied in junior high school is not as good as the whole chemistry.

All the knowledge in junior high school: compounds, element names, valence, reaction equations, solubility, properties of some chemical substances, etc., these are the most basic, just like numbers in mathematics, how can you learn mathematics if you don't know how to count (although the words are ugly, but a truth).

It is recommended that you think differently and learn to synthesize, such as the synthesis of mathematics and chemistry: how many proportions of reaction can be found to reach the maximum? (The problem of finding the maximum value in mathematics), the synthesis of physics and chemistry: two reactions on both sides of the pulley, finding the velocity after the pulley reaction is completed, etc.

Read more textbooks, memorize some important things, and be sure to read more textbooks.

I think it's good to lay a good foundation in chemistry for students, after all, it is the real meaning of junior high school chemistry.

I am also a student.

Go find a book for the first year of high school and see if there is anything you can talk about together, but if it is not the end of middle school, the principal should ask for the review and review of the things in the third year of junior high school.

I am a student.

As a chemistry major, I think that in order to make students do a good job in the transition from junior high school to high school, junior high school chemistry teachers should infiltrate some chemistry knowledge related to junior high school chemistry but learned systematically in high school in their usual teaching, which can be problem-solving methods or theoretical knowledge.

The junior high school stage is to carry out the "introductory" teaching of the most basic chemical knowledge and skills to all junior high school students according to the requirements of nine-year compulsory education, which focuses on improving the quality of the whole nation; High.

1. The compulsory chemistry course in the second year of high school is a teaching for all high school students to further popularize and deepen their chemistry knowledge to adapt to a variety of social choice abilities; The chemistry elective course in the third year of high school is to improve the teaching of chemistry knowledge according to the personal strengths and interests of some students. This systematic and phased division reduces the burden of students' homework, overcomes the phenomenon of partial subjects, and creates conditions for improving the quality of chemistry teaching on a large scale. However, there are many things to be done on how to do a good job in the "connection" of chemistry teaching at each of the two stages.
