Freshmen in Senior High School: How to Learn Math Well in Senior High School
4. Differences in thinking habits Junior high school students have a small range of learning mathematics knowledge, a low level of knowledge and limited knowledge, and their thinking about practical problems is limited. As far as geometry is concerned, we have all been exposed to the three-dimensional space in real life, but we only studied plane geometry in junior high school, so we can't think and judge the three-dimensional space strictly. The range of numbers in algebra is limited to real number thinking, and it is impossible to solve the type of equation roots in depth. The diversity and extensiveness of senior high school mathematics knowledge will enable students to analyze and solve problems comprehensively, meticulously, profoundly and rigorously. It will also cultivate students' high-quality thinking. Improve students' progressive thinking. 5. The differences between quantification and variables in junior middle school mathematics, topics, known and conclusions are all given by constants. Generally speaking, the answers are constant and quantization. When students analyze problems, most of them are quantitative. Such a process of thinking and solving problems can only solve problems unilaterally and restrictively. In high school mathematics learning, we will widely use the variability of algebra to discuss the universality and particularity of problems. For example, when solving a quadratic equation with one variable, we use the solution of equation ax2+bx+c=0 (a≠0) to discuss whether it has roots and all the roots when it has roots, so that students can quickly master the solutions of all quadratic equations with one variable. In addition, in the high school stage, we will explore the ideas of analyzing and solving problems and the mathematical ideas used in solving problems through the analysis of variables. A good beginning is half the battle. Senior high school math class is about to start, which is related to junior high school knowledge, but it is better than junior high school math knowledge system. In senior one, we will learn functions, which is the focus of senior high school mathematics. It plays an outline role in senior high school mathematics, and it is integrated into the whole senior high school mathematics knowledge, including important mathematical thinking methods in mathematics. For example, the idea of functions and equations, the idea of combining numbers and shapes, and so on. This is also the focus of the college entrance examination. In recent years, the final questions of college entrance examination are all entitled functional investigation methods. The exercises related to function thinking methods in the college entrance examination account for more than 60% of the whole test questions. Tu 1。 Have a strong interest in learning. More than 2,000 years ago, Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy." It means that it is better to love something than to do it, to know it, to understand it, and to enjoy it than to like it. "Good" and "happy" mean willing to learn and enjoying learning, which is interest. Interest is the best teacher. Only when you are interested can you have hobbies. If you like it, you have to practice and enjoy it. With interest, we can form the initiative and enthusiasm of learning. In mathematics learning, we turn this spontaneous perceptual pleasure into a conscious and rational "understanding" process, which will naturally become the determination to learn mathematics well and the success of mathematics learning. So how can we establish a good interest in learning mathematics? (1) preview before class, and have doubts and curiosity about what you have learned. (2) Cooperate with the teacher in class to satisfy the excitement of the senses. In class, we should focus on solving the problems in preview, regard the teacher's questions, pauses, teaching AIDS and model demonstrations as appreciating music, answer the teacher's questions in time in class, cultivate the synchronization of thinking and teachers, improve the spirit, and turn the teacher's evaluation of your questions into a driving force to spur learning. (3) Think about problems, pay attention to induction, and tap your learning potential. (5) Let the concept return to nature. All disciplines are summarized from practical problems, and mathematical concepts are also returned to real life, such as the concept of angle, the generation of polar coordinate system and the generation of polar coordinate system are all abstracted from real life. Only by returning to reality can the understanding of concepts be practical and reliable and accurate in the application of concept judgment and reasoning. 2. Establish a good habit of learning mathematics. Habit is a stable and lasting conditioned reflex and a natural need consolidated through repeated practice. Establishing a good habit of learning mathematics will make you feel orderly and relaxed in your study. The good habits of high school mathematics should be: ask more questions, think hard, do easily, summarize again and pay attention to application.
