Hua, a famous mathematician in China, said: "The universe is big, the particles are tiny, the speed of rockets, the cleverness of chemical engineering, the change of the earth and the complexity of daily use, and mathematics is everywhere." This passage brilliantly illustrates the application of mathematics in real life. Nowadays, the ideas and methods of mathematics have penetrated into all aspects of society, and the application of mathematics has been paid more and more attention. However, the current mathematics classroom pays more attention to students' problem-solving ability, but ignores understanding mathematics from real life. Therefore, students have doubts about the use of mathematics and think that mathematics is useless. In fact, the development of society needs high-quality talents. They should not only learn theoretical knowledge well, but also apply what they have learned. The purpose of learning mathematics is to apply mathematics to solve practical problems, so it is very important to strengthen students' awareness of applying mathematics and cultivate their ability to apply mathematics in mathematics education. "New Curriculum Standard" said: "The consciousness of mathematics application is mainly manifested in: recognizing that there is a lot of mathematics information in real life, and mathematics is widely used in the real world; In the face of practical problems, we can actively try to apply the knowledge and methods we have learned from the perspective of mathematics and seek strategies to solve problems. " This requires math teachers to start from the reality of students' lives, tap students' potential, let students experience that mathematics is closely related to life, and cultivate their ability to find math problems from life and solve practical problems with what they have learned.

Second, how to cultivate students' mathematical application ability

1. Teachers should always infiltrate students with the consciousness of applying mathematics and look at problems from a mathematical perspective.

The world we live in is full of mathematics, and people's food, clothing, housing and transportation are all related to mathematics. Shopping often encounters the problem of discounted sales; Driving on the road will encounter travel problems and so on. Teachers should always extract mathematical problems from their lives and infiltrate students with the consciousness of applying mathematics at all times, so that students can feel that mathematics is inseparable from us. They should learn math well and look at problems from a mathematical perspective.

2. Combine classroom teaching with practice to improve students' learning interest and enthusiasm.

When teaching mathematics, math teachers should not blindly emphasize memorizing concept theorems and formula rules, which will arouse students' disgust and make them feel that math classes are too boring and bored with learning. Psychological research shows that the closer the learning content is to the life situation that students are familiar with, the higher the degree of students' conscious acceptance of knowledge. Therefore, mathematics teachers should pay attention to combining all aspects of mathematics classroom teaching with students' real life as much as possible.

Introducing new courses from life examples

Create problem situations in the lead-in, lead out the mathematics knowledge to be taught from life examples, stimulate students' interest in learning, and make them learn mathematics actively.

For example, when introducing "the nature of the vertical line segment", I designed the following scenario: "The bus company wants to build a bus stop between two communities along the highway, and the residents of both communities want the bus stop to be closer to themselves. To be fair, please help the bus company find a way. Where is the bus stop built, and the distance to the two communities is the same? " Hearing this, the students immediately became interested and had a heated discussion, but in the end they didn't decide where to build it. At this time, I also said that this problem can be solved as long as we learn the perpendicular nature of the line segment well. This introduction can not only enliven the classroom, but also make students realize the important role of mathematics in life and stimulate their thirst for knowledge.

(2) explain the examples as far as possible.

Although the textbooks we are currently using for the new curriculum reform have paid great attention to compiling examples from the reality of life, they still cannot meet the actual needs of all students. Therefore, mathematics teachers should combine the local actual teaching situation, and make appropriate adaptation of some unfamiliar contents in the teaching materials without affecting the teaching requirements, and replace them with problems close to students' real life, so that students can easily understand and accept what they have learned and their learning enthusiasm will be greatly improved.

(3) Math exercises and homework should be daily.

Math teachers don't have to stick to the exercises in textbooks. They can set out from reality and write their own exercises and homework questions, so that students can apply what they have learned and improve their math application ability.
