Abstract: The development of quality education and mathematics requires junior high school students to actively participate in and cultivate their interest in mathematics learning. For various reasons, junior high school students easily lose interest in mathematics learning, and mathematics learning is mainly passive-studying for exams. Therefore, it is particularly important to cultivate students' interest in mathematics classroom teaching in junior high school.

Due to the difference in mathematics requirements between junior high school and primary school, many students lost interest in learning mathematics as soon as they entered junior high school, and some even became afraid of mathematics. Mathematics gives people the impression of boring letters and complicated calculations, and the new mathematics textbook (Zhejiang Education Press) has increased the flexibility of learning to some extent. It is one of the goals of mathematics teaching to stimulate students' interest in learning mathematics, let students gain successful experience and establish self-confidence in learning mathematics well. Teachers are the organizers, guides and collaborators of students' mathematical activities. So, how to form students' good emotional attitude and values through effective teaching? I think it is necessary to advocate the life of mathematics teaching content, the flexibility of methods, the interest of design, the diversity of evaluation and the novelty of means.

Second, the text

1. Direct attraction of interest

1) Use language to attract students.

Mathematics is a subject with strict logic, but it is also very interesting. When implementing the teaching content, we can combine the teaching content with students' actual level, and use vivid and infectious language to stimulate students' interest in learning, thus improving classroom efficiency, such as "Can you do it?" "You finally succeeded through your own efforts!" Wait, these inspiring words have greatly stimulated the students' enthusiasm for learning. When students seek the reciprocal of negative numbers (the first volume of seventh grade mathematics of Zhejiang Education Publishing House), they often forget symbols, so I asked: Can a male classmate become a female classmate by doing handstand? On the number axis, it represents positive number, negative number and zero respectively (the first volume of seventh grade mathematics of Zhejiang Education Publishing House). I said to the students, "Brother Zheng stands on the right, Brother Negative stands on the left, and Sister Zero (Lin) stands in the middle." Students remember these knowledge points in laughter. Beautiful and interesting language and interesting examples can give people beautiful reverie, stimulate students' enthusiasm for learning and enhance their confidence in overcoming difficulties and making progress.

Language is a tool for emotional communication and enlightening thinking. Teachers should skillfully use life-oriented, interesting and childlike language to infect students according to the age characteristics of primary school students, the characteristics of mathematics subjects and students' hobbies, so that students can learn mathematics in an interesting language atmosphere and add a new and different color to boring mathematics classroom teaching. Life is the source of mathematics, and the mathematics content that students study should be realistic, interesting and challenging. Such content is conducive to students' active participation in observation, experiment, guessing, verification, reasoning, communication and other mathematical activities, and is conducive to cultivating students' interest and literacy in mathematics. For primary school students, the common sense and experience of mathematics formed in life are the basis for them to learn mathematics. In mathematics classroom teaching, we should use realistic content to arouse students' interest in learning mathematics.

2) Attract students with actions.

Bright graphics can promote the concentration of attention, stimulate thinking activities and enhance interest in mathematics. When students talk about "three-line octagon" (the first volume of eighth grade mathematics of Zhejiang Education Press), when they can't distinguish two congruent angles, inner angles or inner angles on the same side, they demonstrate with their hands, which makes students feel novel. It turns out that the three-line octagon can be found in this way, and they have followed suit. When I was talking about the three views, because it was abstract, I used the chalk box on the podium to constantly change the graphics, and then told the students that it was the same to replace the chalk box with an eraser. Students should try it after class.

3) Attract students with grades

The so-called "achievement motivation" is a kind of motivation aimed at demanding high standards and striving for the success of activities, which is the need for individuals to succeed. A student always hopes to get bigger and better grades in his own mathematics study, which is one of the main driving forces to promote students' learning. Suhomlinski, an educator in the former Soviet Union, said that "the joy of success is a huge emotional force, which can promote children's desire to study hard." Set different grades to fully mobilize students' enthusiasm; Let students strive to be "teachers", students are also interested, they will actively participate, and the following students are also very involved; Because math exercises are difficult, students can always feel the sense of accomplishment of solving problems successfully and get practical results.

4) Attracting students with the beauty of mathematics

Mathematics is the crystallization of thousands of years of human civilization and an important part of human culture. It has rich humanistic value. The combination of pure reason and perfect rigorous form contains many aesthetic features, such as the golden section. In all aspects of teaching, the beauty of mathematics is also displayed at any time, for example, the symmetry of mathematical formula and geometry, the beauty of harmonious image, the beauty of straight line giving people bold and straightforward, the beauty of Pythagoras number giving people wonderful data, the simplicity and vividness of geometric proof, the multiplicity of mathematical problems, and the multiplicity of many problems embodies the beauty of mathematics everywhere.
