How to do a good junior high school physics review class?

Of course, you have to listen carefully in class, and the homework left by the teacher must be completed independently, and you should ask questions frequently if you don't know, or wait for the teacher to talk in class (junior high school class time is relatively relaxed, the teacher should teach the exercises, if you don't talk about it, ask the teacher, the teacher will not say you). In addition, don't look for too many and too difficult extracurricular questions, which will increase the pressure, but a moderate amount is still possible. The content of the third year of junior high school here is more than the content of the second year of junior high school, and the part of electricity must be learned well.

Finally, I wish you a good result in the high school entrance examination.

First of all, you must listen carefully in class, do not ask questions in response to problems, and remember the method.

In fact, a series of problems are the same, and the methods are the same, and especially the physics in junior high school is born by a mother.

You must do the problem independently, you can not calculate, but you must figure it out and know how to do the problem.

As long as you master the method, you will find that the questions on the paper are all the same.

In my experience, I should apply the physics knowledge I have learned to solve practical problems, and do not simply review the basic concepts many times, but use them more after the basic feeling review, so that students can truly understand what they have learned in the process of application. For example, in a home circuit, what happens when the total power of the appliance is too high? Some students say that the current in the wiring will be too large, and the electrical appliances will be burned out, and the fuse will be blown out.

I ask students to discuss whether the answer is correct or not. Thus reviewed, the characteristics of parallel circuits, the voltage division characteristics of series circuits, Joule's law, actual electrical power and other knowledge, and it is very practical.

Listen carefully in class. Do the questions carefully. Think more.

In the junior high school physics review class, we should first recall the knowledge we have learned and form a network, find the connection between the knowledge points, and then apply it through typical examples, and then consolidate the exercises.

The summary is the most important, including the summary of the classroom teacher, the summary of the self-preview review after class, the summary of the wrong questions, it is best to find a book, record the experience, it is usually more than flipping, for the formula, the memory also needs to be understood, according to the specific situation appropriate use, pay attention to the scope of application of the formula.

Don't equate physics with mathematics, and develop a good habit of writing for special calculation problems.

For most problems, the diagram is quite important, the key to the electrical circuit diagram is to simplify, we can distinguish the connection situation at a glance, the force analysis of mechanics is the basis of the problem, the optical path diagram can help us analyze the problem, and even the boiling evaporation of heat will use the diagram.

Of course, it's easier said than done, but don't be pressured, I think the key to junior high school physics is to get started, and touch the class will be bypassed.

Practice a lot, do a lot of practice, physics is very interesting.

Chemistry: The basis of chemistry is nothing more than elements and chemical reactions, and I think you should first have a good grasp of the principles of chemical reactions and know what chemical reactions are.

The steps are as follows:

1. Have a deep understanding of what a chemical reaction is and what are the main components of a chemical reaction.

2. To learn redox reaction, you must know what is oxidation reaction and what is reduction reaction.

3. Memorize and memorize commonly used chemical reaction equations and typical chemical reaction equations.

4. Read the texts carefully to enhance your interest in chemistry.

5. Enhance extracurricular exercises, and it is recommended to choose some exercises with low difficulty to enhance your confidence.

Responses to multiple-choice questions:

Multiple-choice questions are characterized by strong conceptuality, pertinence, and a certain degree of confusion. It mainly tests students' judgment and comparison skills. There are two main ways to respond: (1) Direct judgment:

Use concepts, laws, and facts to directly determine which option is completely positive, and select the only correct answer; (2) Elimination method: If you can't be completely sure that a certain option is correct, you can also be sure which options must be incorrect, first eliminate them, do careful analysis and comparison among the remaining options, and finally determine an option. Multiple-choice questions must not be left unanswered.

Responses to multiple-choice questions:

One or several of the options are correct, but it is not certain that the other options must be wrong, and the method used is mainly direct judgment, and do not force the choice of hesitant conclusions, so as not to affect the score.

Answers to fill-in-the-blank questions:

Fill-in-the-blank questions do not require a written thought process or a calculation process, but they do require a high degree of judgment and accurate calculation skills. Answers to conceptual questions should be precise and concise; Answer the calculation questions accurately, including the number of digits, units, plus and minus signs, etc., and do not reverse the calculation of proportionality.

Answer to the drawing question:

It mainly tests students' drawing skills and ability to apply methods to solve problems. In the drawing problem, one is qualitative and the other is quantitative. Serious about qualitative drawing, such as drawing light paths, arrows in force icons, etc., should use a ruler, not too sloppy; The quantitative drawing must be accurate, such as the graphical solution of the force, the determination of the focus in the lens, etc.

Answers to experimental questions:

There are four types of lab questions.

1) the use of experimental instruments and measuring tools;

2) Confirmatory experiments and measurement experiments done by students, including experimental objectives, experimental principles, experimental equipment, experimental procedures, experimental data and data processing, error analysis, etc.;

3) Demonstration experiments that teachers have done in class or experiments drawn in textbooks;

4) Design some simple experiments according to the requirements of life and production. In order to be able to answer the experimental questions well, it is necessary to keep the various experiments and requirements in mind without actual equipment, and answer strictly according to the requirements in the questions.

How to learn physics well? Here are 11 specific learning methods.

1. Do some questions independently (meaning not relying on others) and with quality and quantity. Solving problems independently, sometimes slowly, sometimes detours, but this is the only way to success.

2. The physical process should be clear about the physical process, and there will inevitably be hidden dangers in solving the problem if the physical process is not clear. Regardless of the difficulty of the topic, try to draw as much as possible. Drawing can transform abstract thinking into figurative thinking and grasp physical processes more precisely.

With graphs, state analysis is fixed, dead, and intermittent, while dynamic analysis is alive and continuous. 3. Listen carefully in class and don't get distracted.

4. Notebook class is mainly for listening to lectures, and there must be a notebook, and there are some things to write down. Knowledge structure, good problem solving methods, good example problems, things that you don't understand well, etc., should be written down. After class, I also have to organize my notes, on the one hand, to "digest well", and on the other hand, to supplement my notes.

5. Learning materialsLearning materials should be preserved, classified well, and marked. The study materials are categorized into practice questions, test papers, lab reports, and more.

6. Time is precious, and there is no time to do anything, so we should pay attention to making full use of time, and using time is a very superb art.

7. To learn from others, we should learn from others with an open mind, learn from our classmates, learn from the people around us, see how they learn, often communicate with them "academically", teach and learn from each other, improve together, and never be self-righteous.

8. The knowledge structure should pay attention to the knowledge structure and systematically grasp the knowledge structure, so as to systematize the scattered knowledge. It is as large as the knowledge structure of the whole physics, as small as the knowledge structure of mechanics, and even down to the chapters, such as the knowledge structure of statics, and so on.

9. The calculation of physics depends on mathematics, which is too important for learning physics. Learn mathematics well and make good use of mathematics as a powerful tool.

10. Physical activity: A healthy body is the guarantee of good learning, and vigorous energy is the guarantee of high learning efficiency.

11. The three basic concepts should be clear, the basic laws should be familiar, and the basic methods should be proficient. In the process of learning physics, it is very useful to summarize some concise, easy-to-remember and practical inferences or assertions to help solve problems and learn physics well.

Listen to lectures with an open mind, notes are very important, and every class must be serious, if you don't understand each class, you should ask the teacher immediately, the old teacher is very happy to help you answer, don't be embarrassed, I'm sorry to kill people, physics class is difficult to learn, but as long as you take notes carefully, there is a preview before class, it is very easy, and more classmates, teachers, physics once and another class did not listen, it is basically difficult to keep up, so it is said that you have to work hard to learn physics. The above banquet is purely personal learning opinion, I hope it can be helpful to you!

Physics: Mainly the understanding of concepts and scrambled formulas. For concepts, you must grasp them well, and doing more multiple-choice questions will help you grasp the understanding of concepts.

But you must take each question seriously and understand each option when you do it. Calculation questions are accurate formulas. Therefore, it is necessary to have a special understanding of the meaning of the formula.

Practice more, the questions are actually many similar.

The more you know, the better you learn, so remember more and choose your own method.

Good luck with your studies!

It's important to experiment. Introduce concepts to relate to the things around you. Understanding of concepts and formulas. Teach some exercises and let students use their hands and brains more.

When it's time for a review class, listen carefully! And you should take notes diligently, write down the teacher's board book, solve the problem, and listen carefully to the teacher's comments on the solution ideas of each question, as well as... Which steps can not be less, which need to pay special attention, generally speaking, if you review, the teacher will generally tell you about the exam tendencies in recent years, and you should pay more attention to this aspect. . . .

The more you get to the end, you'll be very tired.,There's no need to immerse yourself in the tactics of the sea of questions.,Find out the test papers you've taken before.,What are the practice questions you've done and look at it again.,Do it again.,You must figure out the questions you don't understand.,Do it a few more times.,Deal with them one by one.,Don't accumulate more and more.。。。

Generally speaking, that's all, and it's important to be serious during the exam, don't be careless, make those low-level mistakes, such as the unit is not converted, and the question stem can't be seen clearly, although I'm always careless about these, but I still have to remind myself, after all, I can drill a point is a point...

Anyway, learning everything well is different from person to person, as long as you want to do it, and you must do it, you will definitely succeed, the most important thing is to see if you can really calm down and concentrate on it
