For a long time, our teaching has been divorced from the reality of life, and some figures have been artificially set to teach students to learn to calculate, but some practical problems in life cannot be solved. Although students study well, their practical ability in real life is poor and they can't solve specific practical problems. With the development of society, the requirements for talents have changed, and teachers' educational concepts should also change. The examples in the new textbook are all based on life, and the introduction of every knowledge starts from the dribs and drabs of life, so that students can receive practical problems in life through graphics, instead of written knowledge as before, which is actually practical knowledge. Written knowledge cannot reflect practical problems, so that students can't start when solving practical problems. Therefore, teachers are required to change their teaching concepts, be close to life, combine teaching with practice, proceed from reality, teach books well and educate good people.
For example, on page 84 of the first volume of the third grade of the People's Education Edition, about "a factor is multiplied by 0", there is such a problem: an old man with a gray beard is walking in the lakeside park. The text is only "I walk 508 meters three times a day". The question asked by the elf is "Can you figure out how many meters the old birthday girl walks every day?" ? It is wrong to teach students to calculate 508×3 only. The knowledge points in this section include the estimation of the distance that the birthday boy walks by the lake every day and the estimation of the product of 508×3. The lakeside environment is beautiful, with mountains, water and people, which creates a harmonious relationship between man and nature and builds a beautiful and elegant environment. In this environment, the body is so strong. Explain that the essence of life lies in exercise. An old man with a gray beard is in good spirits and strong body because he keeps exercising every day. Through this example, students are warned to love sports, keep exercising, protect the environment and take care of flowers and trees.
Another example: the seventh question on page 48 of the first volume of fourth grade mathematics: "Every tree seedling 16 yuan, if you buy three trees, you get 1 tree. Ask how much each tree is cheaper? " If you buy three trees at a time, the money payable is 3× 16=48 (yuan). Because if you buy three trees at a time, you get 1 tree, but you actually get four trees, that is, 48 yuan buys four trees. In fact, each tree only pays 48÷4 = 12 (yuan), which is cheaper 16- 12 = 4 (yuan) Topic analysis: it is a means taken by flower shop owners to promote sales, buy three and get one free. Encourage customers to buy flowers to achieve the purpose of selling flowers for profit. In fact, in real life, commodity exchange is everywhere, isn't it? In the extremely developed social environment of commodity economy, editors should not only arrange such topics for students, but more importantly, teachers should educate students to have business awareness.
In real life, goods are dazzling, how to promote products? Commercial promotion measures such as small profits but quick turnover, price reduction promotion, buy a few and get one free can be taken. It is necessary to attract customers and businesses, and realize that there is competition in the industry, how to survive in the competition and how to develop. Think about it, whether there is competition in other industries is obviously certain. Since there is competition everywhere in life, we should have a sense of "competition" from an early age and have the courage to overcome difficulties. Therefore, as teachers in the new century, we should guide children how to build up the courage to overcome difficulties. Educate students to be strong-willed. No matter what they do, they should use their brains and think more, and their methods should be diversified in order to succeed.
Teachers are engineers of human souls and guides of students. In order to cultivate talents to adapt to modern society, teachers' educational concept must be changed, not only to teach students to calculate, but more importantly to educate students to solve practical problems in life. Cultivate students to have a positive and healthy attitude, reflecting that there is mathematics everywhere in life, and mathematics serves our life. Therefore, the mathematical examples listed in education and teaching must be close to life. Especially in the process of guiding students to read and look at pictures, we must guide students to understand the meaning of pictures and make a comprehensive analysis of them. We can't just analyze mathematics problems and ignore the practical problems close to life, so that students can experience the existence of mathematics in real life, so as to learn mathematics well and achieve the teaching purpose.
