Before each new lesson, you should preview it first, especially draw or mark the difficulties or things you don't understand with colored strokes, so that you can concentrate more in class. Preview is a prerequisite for learning every subject. Make different preparations for students' different learning abilities. Students with good grades and strong learning ability can look at examples and do classroom exercises at the end of each class, so that they can understand 70% of the new content and do 80% of the exercises. Students with poor grades just need to look at the examples and copy them well. Be familiar with the examples and the contents of this section in the book, so that they can have a good idea of the examples and listen to the lectures. This is a good learning method. Even the worst students should know something about the content and knowledge of this lesson. After learning a new lesson, we should compare and review the learned knowledge step by step according to the contents of the textbook, from easy to difficult, from simple to complicated, and summarize the concepts, theorems and formulas to deepen our understanding of knowledge. The examples in the textbook are best done by yourself. Reasoning the concepts, theorems and formulas in the textbook to form an overall understanding of knowledge.
Second, listen carefully, take notes and think in class.
Listen to the questions in the preview in class, take notes when necessary, and consolidate them through some exercises. Mathematics is different from other subjects. It is impossible to solve practical problems by memorizing concepts, theorems and formulas. Only through practice can we reduce operational mistakes.
Third, homework should be "thinking, asking and gathering"
Homework must develop the habit of independent thinking, from different methods and angles, explore a variety of problem-solving methods from typical topics, and get association and inspiration from them. The examples in the textbook are typical, and we can find the solution from the examples. At the same time, we should also establish more mathematical problem-solving ideas, such as: equation ideas, function ideas, combination of numbers and shapes and other common methods; For difficult questions, we should ask more reasons, such as changing conditions, adding conditions, and exchanging conditions for conclusions. Is the original conclusion still valid? In addition, for the mistakes in homework and test papers, it is best to prepare a set of wrong questions for future review. Never make a second similar mistake, never make a third similar mistake.
Learning mathematics should have methods, plans and reasonable arrangements. After the new lesson, some students feel headache, so they look around and don't know what they have learned in the end. Therefore, every student should work out reasonable learning methods and goals according to his own actual situation; If there is no way, it will become a headless fly; Without goals, there will be no motivation.
After mastering some methods of learning junior high school mathematics, we should also note that junior high school is a special and crucial period in the life of middle school students. Compared with primary school mathematics learning, junior high school mathematics learning has certain differences. For example, compared with the previous courses, junior high school mathematics not only increased the amount of knowledge, but also made a qualitative leap-requiring students to master mathematical thinking methods on the basis of a deep understanding of concepts and to comprehensively use what they have learned to solve problems. Therefore, junior high school students should learn to study mathematics better now in order to successfully provoke new learning responsibilities.
In addition, we should also clearly realize that junior high school mathematics should be accompanied by a certain review process in the process of learning. In the process of review, there are many knowledge points, which can easily give students a sense of disorder. Therefore, when learning junior high school mathematics, it is necessary to establish a knowledge network system for application in review and problem solving.
We have learned a lot of knowledge points and done a lot of problems, but the impression in our minds is often vague and isolated. We must compare and sort out the connections and differences, and weave knowledge into a net, so that we can solve problems with confidence, use them freely and form the ability to solve problems. For example, what kind of quadrilateral can be determined as parallelogram, rectangle, diamond or square? There are several ideas to consider. What are the properties of their sides, corners and diagonals? What about symmetry? Let's summarize.
Learning junior high school mathematics well is an arduous and imperative task. As a math teacher, we should stand on the students' side, guide them to correct learning ideas, do a good job in reviewing and studying in junior high school, make students not afraid of learning math, and guide them to fall in love with and like math, so as to learn math well.
