Most students get tired of math as soon as they get to middle school. They don't like math classes or math teachers. In my opinion, in order to eliminate students' negative psychology in learning mathematics and improve the quality of mathematics teaching, in addition to conventional teaching methods and ordinary classroom methods, we need to make greater efforts in cultivating students' interest in learning mathematics, enhancing students' confidence in learning mathematics and improving students' learning ability. It is boring to create students' interest in learning mathematics from the characteristics of mathematics itself, which requires teachers to create suitable teaching situations, use intuitive and novel educational means and use game-based learning methods to make students feel that the learning process is full of fun. For example, in the teaching of geometry knowledge, it is necessary to provide more corresponding objects, models and intuitive views, so that students can observe from multiple angles in an orderly manner, fully perceive with multiple senses, enhance their perceptual knowledge of geometric shapes, and deepen their perception, knowledge, understanding and memory of their shapes, characteristics and spatial positions. If students can make some models by themselves, they can use their own models as teaching AIDS in class, which can not only enliven the classroom atmosphere, but also make all students have a sense of intimacy. It is best to use things made by ourselves or the closest people to help us learn math knowledge in class and in the hands of teachers. Through the operation of teaching AIDS and learning tools, students can feel that mathematics is on our desks, in our hands and around us, which can enhance students' interest in learning to a greater extent. In mathematics teaching, not only the learning of geometry knowledge, but also the learning of other knowledge needs to strengthen intuition, demonstration, operation and experiment, so that students can fully understand mathematics knowledge. Because only what is understood can leave a deeper memory and be used better. Modern teaching media provides us with a simpler method. In mathematics teaching, we should fully arouse students' enthusiasm for inquiry and let them learn independently like a little "mathematician". Trying teaching method runs through "hands-on operation, independent exploration and cooperative communication", which is an important way for students to learn mathematics. It attaches great importance to students' independent exploration and learning process, is good at creating situations, helps and promotes students' interest and curiosity in learning mathematics, and mobilizes students' enthusiasm for exploration. Stimulate and cultivate students' interest in learning mathematics in many ways. After all, mathematics learning is not an isolated study, but should be integrated into the teaching activities of the whole school. Therefore, the cultivation and improvement of students' interest in mathematics learning need to permeate the whole teaching activities. Therefore, we must stimulate and cultivate students' interest in learning from many aspects. Ausubel, a famous educational psychologist, believes that achievement motivation is the most important among all the factors that constitute learning motivation. Therefore, in mathematics teaching, teachers should fully mobilize students' sense of accomplishment, so that students can persist in persistent, regular, disciplined and monotonous learning activities, overcome their laziness and procrastination tendency during the period, and win students' personal self-esteem and higher class status in their efforts to pursue short-term goals. For excellent students, achievement motivation and academic performance can promote each other and form a virtuous circle.
