Many students say that it is boring to finish junior high school mathematics. The main reason why many students can't learn math well is not intellectual factors, but psychological factors. Prejudice affects their learning effect. "Interest is the best teacher" How to eliminate students' fears, the mathematics textbook of Beijing Normal University has made a good attempt in this respect. Avoid using mathematical terms and choose some suggestive or familiar life events as titles, which increases the affinity of mathematics. For example, the quantity is not enough, and the water level changes, especially the unary equation in Chapter 5, such as "How old are you this year", "Equation in the calendar", "I have gained weight", "Sale at a discount", "Hope Project Charity Show", "Can you catch up with Xiaoming" and "Education Savings" and other familiar things have not only been eliminated. Enhance the operability of mathematics, combine mathematical knowledge with practice, improve students' learning enthusiasm, and make them willing to learn and want to learn mathematics well.

Second, add new application content, strengthen brain operation, weaken tedious calculation process, expand students' thinking space and enable them to learn.

Today, when quality education is advocated, we should put students' dominant position in the first place. The mathematics textbook published by Beijing Normal University provides us with a new teaching mode of "discovery-discussion-summary-explanation, demonstration-practice", which allows students to fully participate in the process of problem discovery and solution. Through a series of practices, the textbook enables students to exert their intelligence and realize the two-way interaction between teaching and learning.

For example, the first chapter "Rich Graphic World", I think it may be difficult for students to master this chapter, but students can effectively cultivate abstract spatial thinking in practice by doing geometry, cutting geometry and watching geometry, and their mastery is better than rational numbers and their operations. For another example, after reading the second section of chapter 4 in the mathematics textbook of Beijing Normal University (Volume 7), students have a debate about the distribution of cakes. There are three main distribution methods: ① Because A gets 8 points and B gets 7 points, the cake should be divided into 15 equal parts, with A getting 8 parts and B getting 7 parts; Because coin toss is a fair game, before the game is over, both parties have a 50% chance of winning, so both parties should share the cake equally. Because A scored 1 point more than B, all the cakes should be given to A. This discussion greatly mobilized the enthusiasm of students in using mathematics and cultivated their open thinking. There are such arrangements in many places in the textbooks of Beijing Normal University.

Third, the teaching materials are arranged in a spiral structure, which lays the foundation for students to learn mathematics well.

We once described mathematics as a chain, and each lesson was a link in this chain. This is because the previous mathematics textbooks have adopted a compact structure, and each chapter is closely related. What link goes wrong directly affects the following sections and even chapters. Teachers have a clear main line when dealing with textbooks, but in teaching practice, in order to let students have time to consolidate the knowledge of the previous chapter, algebra textbooks and geometry textbooks are often used alternately, and there is even a phenomenon that they specialize in which one to learn at a certain time. In the process of learning, facing the key points and difficulties, students' understanding ability is also restricting the learning effect. In order to improve the ability to use knowledge, it is necessary to practice repeatedly, and students are caught in the ocean of imitation, training, imitation and retraining. The textbook of Beijing Normal University adopts spiral structure. This form is not simply repeating the content. Teaching materials will put forward new requirements at each stage, disperse and resolve difficulties step by step and gradient, and reduce students' learning pressure. For example, in the first semester of junior high school, it is mainly numbers and expressions. This part is the basis of whether junior high school algebra can be learned well, which is more important. Now this part of the content is divided into two semesters, which effectively relieves the learning pressure of students; The third grade is mainly a function, which is often difficult for students to understand. Although they can solve problems, they can't establish functional ideas. The textbook of Beijing Normal University began to permeate the function thought from the seventh grade, and helped them to establish the function thought through a large number of facts, achieving a natural effect.

Fourthly, the "Z+Z" intelligent education platform is applied to junior high school mathematics, which is convenient for teachers to change the traditional mathematics teaching mode.

Under the guidance of the new curriculum standards, mathematics classroom teaching should be based on students' development, centered on thinking training, based on rich information resources and supported by modern information technology. Through independent exploration, cooperative discussion and active innovation, students can improve their knowledge and skills, meet the needs of interest and emotion, and improve their mathematical literacy. "Z+Z", as a teaching aid, emotional motivation tool and cognitive tool for students, can maximize the construction of digital learning resources and enable students to realize the transformation of learning methods, from passive acceptance of learning to independent inquiry learning and meaningful learning. At the same time, it also provides an operable environment for teachers to adjust their position and establish students' dominant position. In the past, many problems were explained clearly by teachers. Now, first, let students contact with problems, and cultivate their problem-solving ability and thinking ability through their own observation and thinking. It promotes the fundamental change of students' learning style and opens up a new world for middle school mathematics teaching.

In the course of one year's use, I deeply realized that the textbooks of Beijing Normal University left a lot of space for students. Our teachers should adjust their position in time, change themselves from "athletes" to "referees" in classroom teaching, establish students' dominant position in teaching, and correctly guide students to give full play to their intelligence, so as to achieve twice the result with half the effort.
