Knowledge quantity and abstraction: Compared with high school mathematics, junior high school mathematics covers fewer knowledge points and is more concrete and vivid. This makes it relatively easy for junior high school students to understand and master when studying. However, high school students have more mathematical knowledge and involve more abstract concepts, such as set, function and space geometry, which requires students to have strong abstract thinking ability, so it is more challenging for high school students.
Computational complexity: The calculation of junior high school mathematics is relatively simple, mainly involving basic arithmetic operations and simple algebraic operations. The calculation of high school mathematics is complicated, involving advanced calculations such as algebra, trigonometry and calculus. This requires high school students to have stronger computing ability and solid basic knowledge.
Depth and breadth of knowledge mastery: Junior high school mathematics learning is superficial, which mainly requires students to master basic mathematical concepts and problem-solving methods. High school mathematics requires students to master deeper knowledge points, understand the principles and applications behind them, and also need to master a wider range of mathematical tools and skills.
Test difficulty: The test of junior high school mathematics is relatively simple, which mainly examines students' understanding and application of basic knowledge points. Senior high school mathematics examination pays more attention to students' comprehensive quality, including mastering knowledge points, applying ability and innovative thinking.
Generally speaking, the difficulty difference between junior high school mathematics and senior high school mathematics mainly lies in the increase of knowledge, the enhancement of abstraction, the improvement of computational complexity and the increase of examination difficulty. But the purpose of improving these difficulties is to cultivate students' stronger mathematical thinking ability and problem-solving ability, and lay a solid foundation for further study of advanced mathematics in the future.
The key to learning junior high school mathematics well lies in the following aspects:
Active preview: have a general understanding of the course content to be studied, so that you can easily keep up with the teacher's explanation rhythm when listening to the class. In this way, it can not only change from being beautiful to being beautiful, but also enhance the listening effect and improve the learning efficiency.
Review in time: After-class review is an extension of classroom learning, which can not only solve the unresolved problems in preview and classroom, but also systematize knowledge, deepen and consolidate the understanding and memory of classroom learning content.
Clarify the key points: through preview and review, you should be able to realize which parts are the key points of learning, focus on these parts and try to solve the difficult problems of these parts.
Multi-angle thinking: when encountering problems, try to think about solutions from different angles and cultivate your thinking ability.
Note-taking: In class, if there is anything you don't understand or important knowledge points, you should take notes in time to facilitate future review.
Establish mathematical thinking: Mathematics is not only memorizing formulas and solving methods, but more importantly, understanding and using these formulas and methods to solve problems. Therefore, we should strive to establish mathematical thinking and understand mathematical knowledge points by thinking about the essence of mathematical problems.
Practice and practice: Mathematics is a subject that needs a lot of practice and practice. By doing problems and solving practical problems, we can better understand and master mathematical knowledge.
Ask for help: Don't be shy when you encounter problems you can't solve or knowledge you don't understand. Ask teachers, classmates or the internet for help in time.
Make a study plan: Make a reasonable study plan according to your study goals and your own situation, and stick to it.
Finally, it should be noted that learning is a long-term process and cannot be accomplished overnight. Only by maintaining patience and perseverance and continuous efforts can we achieve good results.
