I m in the second year of junior high school, what should I do if I have poor grades in science?

Understand the concept first, and if the concept doesn't work, everything won't work. Chemical equations are regular, and there are very few exceptions to the four basic types (compounding, decomposition, displacement, and metathesis). Valency is a must, but you don't have to memorize it all, and it's OK to memorize a few days if you make up a formula for commonly used elements.

Junior high school science is the same thing, it is difficult to say that it is difficult, it is easy to say that it is easy, in fact, there are only a dozen concepts of basic knowledge, and the rest is developed according to this deformation. In short, importance: conceptual theorems (including chemical equations) solution ideas.

t t means that science has not been under 90 chemistry I was dizzy at the beginning Anyway, you just listen to the teacher Listen to it too much and naturally remember it Anyway, the exam will test those common onesFor example, how to produce oxygen, those three methods, must be remembered, there is also carbon dioxide into the clarified lime water, and there are some phenomena of substances burning in oxygen, that's it, > chemical equations have been written a lot, and I have experience, except for a few special ones, other metathesis reactions are swapped positions, and then trimming, it's OK, you don't write less or more elements, it's basically no problem.

In chemistry, I can memorize equations (dead memorize t t), I can balance, and there are very few equations in junior high school, so I don't have to be afraid, but also memorize experimental phenomena. Special attention is paid to the properties of each important pure substance and the method of preparation. (e.g. carbon dioxide, oxygen, carbon monoxide, etc.) ）

Looking for Qiang Mingzhong, a classmate from the second class of junior high school (class of 2011) of Shenzhen Foreign Chinese School in Guangdong Province, he is good at science!! Excellent!!

Be serious in class. Take good notes, and if you don't know how to ask your teacher or classmates, and then organize your notes when you get home. When you're fine, flip through your notes.

It's not that hard to learn chemistry, but there's a law you need to know about: conservation. You just need to remember conservation, what charge conservation, atom conservation, chemical valence change is not difficult, just a simple addition, conventional inorganic chemistry will never produce special substances.

Well, ask me a question, hope.

It is necessary to arrange the study time reasonably.

In the morning, a person's memory is the best, which is suitable for reading English and memorizing words. During the day, self-study classes are arranged for mathematics and physics, and the problem-solving efficiency is higher at this time. The rest of the time will be reserved for Chinese, and you can read more extracurricular books.

Pay attention to the learning methodThe junior high school course is not difficult, you can borrow your classmates' notes to read it, and you also need to review the knowledge you have learned. Secondly, you should pay attention to the learning method. Every day before going to bed, remember what you learned that day.

The key points, difficulties, and common test questions of each chapter should be recorded on note-taking paper in a certain order and glued to the middle of the corresponding chapter. As you read, mark each paragraph, such as "Understood, don't read."

Family education and school education should be closely coordinated as parents must first understand that the foundation of children's intelligence and conduct is laid in the family, and people's intelligence and conduct are formed under the shaping of the family.

In the whole process of school shaping and processing, it is inseparable from the cooperation of correct family education, if there is no good and correct family education cooperation, no matter how good teachers and schools can not produce good educational results. Experienced teachers know that the main reason for this differentiation lies in the coordination of family education. The concept of parental education, which only emphasizes the quality of school education without checking the cooperation of one's own family education, is lacking.

Poor academic performance is a very bad thing for students, but they are discouraged by the school because of their poor academic performance. Specifically, for the matter of being dissuaded from the school because of poor academic performance, it is necessary to pass that poor academic performance is not the reason for being dissuaded from the school, and you cannot go directly to vocational high school after dropping out of school. and students who have been persuaded to withdraw can analyze and respond to the three aspects of protecting their rights and interests in accordance with regulations.

1. Poor grades are not a reason to be dissuaded by the school, and the school cannot use this to dissuade students.

Generally speaking, reaching the point of being dissuaded by the school indicates that the mistake made by the student in question is very serious. But for the student who was dissuaded, the reason the school advised him was simply that his academic performance was relatively poor. Specifically, a student's poor academic performance is not a reason to be dissuaded, and the school cannot use this as a reason to dissuade the student.

2. Students who drop out of school cannot go directly to vocational high school.

In this matter, when the school persuaded the student to quit, he proposed that he go to vocational high school. Such a statement is inappropriate, from the actual situation, students cannot go directly to vocational high schools after dropping out of school. Even the students who were dissuaded did not have the conditions to study in vocational high schools, and because of this, the school's approach was inappropriate.

3. Students who are dissuaded by the school can protect their rights and interests in accordance with regulations.

Since the school's practice of dissuading students is unreasonable and non-compliant, it is not appropriate for the school to recommend that students go to vocational high schools. Then the student who is persuaded to quit can protect his rights and interests in accordance with the regulations, specifically the key argument, he can apply to the relevant departments to solve the problem. In this way, his rights and interests can be protected, so that he can avoid the consequences of being dissuaded.

Of course, the most important thing he should do is to study hard, as long as his academic performance is good enough. You will not be persuaded to quit at all, and you can study happily to strive for better results. Make your future promising.

There are two reasons for poor grades, the first is that the child studies hard, but the grades are not good; The second is that children do not like to read, resulting in poor grades. Here are 3 things you can do to improve your child's grades:

1. Ensure a good reading environment: A good reading environment is one of the main conditions for children to concentrate on reading, and parents should give their children a quiet reading environment.

2. Cultivate children's interest in reading: children are not interested in reading, it may be that parents do not guide children, parents should guide children more, cultivate children's interest in reading, so that children can experience the fun of reading.

3. Help children build self-confidence: Parents should help children build self-confidence, so that children can realize that no matter whether they succeed or fail, as long as they do their best. I remember that when my child was in the third year of junior high school, his comprehension was not good, he was always difficult to memorize English, and his grades in all subjects were not bad.

Later, I searched for the "Tesla Potential Development Course" that can improve intelligence, and after learning it, the situation began to change. My child's grades in all subjects have started to improve. My sharing may be very helpful to you, and I wish you the best of luck too!
