How to quickly improve the grades of high school science students, and what are the Xi methods of mathematics, physics and chemistry?
The foundation of learning a subject well is to take the textbook as the main line, and only by thoroughly understanding the knowledge of the book can we carry out further study and Xi and consolidation. When reading the textbook, every detail should not be missed, and the text, annotations, and experiments in the book need to be read through by students. Do a good job of pre-Xi before class, mark the key knowledge in red, and then you can use the after-class time to learn Xi small print and some charts and other optional content.
How to quickly improve the grades of high school science students, and what are the Xi methods of mathematics, physics and chemistry?
1. How to remedy the difference in mathematics, physics and chemistry in high school
Listen carefully in class
Don't think or think as little as possible. Don't be self-righteous, but learn from Xi teacher with an open mind. Don't give up listening to the lecture because the teacher is simple, if this situation really happens, it can be regarded as a re Xi petition and consolidation. Try to be consistent and synchronized with the teacher, and you can't do it yourself, otherwise it will be completely self-taught. After getting started, with a certain foundation, students can be allowed to have a certain space for their own activities, that is to say, they are allowed to have some of their own things, and the more they learn, the more things they have.
Do the questions independently
It is necessary to do some questions independently (meaning not relying on others) and with quality and quantity. There should be a certain number of questions, not too few, but also a certain quality, that is, a certain degree of difficulty. Anyone who learns Xi mathematics, physics and chemistry will not be able to learn well without going through this level. Solving problems independently, sometimes slowly, sometimes detours, sometimes even unable to solve them, but these are normal and the only way for any beginner to succeed.
Learn to think
Learn without thinking, often because of swallowing dates, for things from the outside world, those who come do not refuse, only know to accept, will not choose, only know how to remember billions, will not always cultivate. Students do not "add their own annotations" in the process of learning Xi, how can they get to Mr. Hua Luogeng's "from thin to thick", students will not "refine the key things", let alone "from thick to thin", to find the essence of the problem, it is difficult for students to make a qualitative leap in learning Xi mathematics, physics and chemistry.
Many children don't know how to think on their own initiativeClasses at Gaotu High SchoolEducation helps children improve their thinking, learn to learn Xi science, and know how to think actively. I am quite pleased that he has a systematic plan for his Xi!
2. High School Mathematics, Physical and Chemistry Xi Skills
1. Organize the knowledge framework and clear the knowledge loopholes.
The first step to learn Xi mathematics, physics and chemistry is to organize the knowledge framework, and the key goal is to establish one's own knowledge system, check the subject knowledge loopholes at the same time, and immediately check and fill in the gaps, clear the Xi obstacles to learning, and establish a foundation for future learning Xi.
2. Lay a solid foundation and focus on learning Xi for basic knowledge.
Basic knowledge determines the room for improvement, and it is a science and engineering science such as mathematics, physics and chemistry, and its knowledge is usually interlocking, and one ring will not be learned if it falls so later. Therefore, if you want to improve quickly, you must first lay a solid foundation of basic knowledge and memorize the laws and formulas before carrying out "actual combat".
3. Multi-solution and intensive problem solving.
"Practicing the truth" is usually applicable to all things, and it is also applicable to the Xi of learning. Therefore, after grasping the laws and formulas, students should carry out "actual combat", and learning to practice is the foundation of learning Xi. However, in the process of solving problems, do not brush the questions, solve more problems but also solve the problems carefully.
About how to quickly improve the grades of high school science students, what are the Xi methods of mathematics, physics and chemistry, I believe you have the answer, and finally to say that children's learning Xi is the same as our work, all need scientific methods and professional guidance, and it is better to plan and guide Xi learning than later.
