On the infiltration of aesthetic education in primary school mathematics classroom teaching

Quotations: "When I look at the sea, I often meditate: Under a calm sea, who says there will be no undercurrent and undercurrent? Just like mathematics, from a distance, it seems to be an abstract kingdom woven by symbols, concepts and propositions. However, when you really walk in, you find that this is actually a vast world full of imagination, vitality, poetry, wisdom and beauty. "
This is the first sentence of my favorite article, which makes me understand that even boring mathematics can make people feel beautiful to most people. Good things are always unforgettable and always make people sincerely happy. Wherever you go, everyone is willing to appreciate beautiful things. The same is true of teaching. One of the purposes of mathematics teaching is to enable students to acquire the aesthetic ability of mathematics, that is, to enhance students' subjective feeling ability of mathematical beauty. If we weave colorful teaching trips, we will firmly grasp the young hearts of children, stimulate their interest in learning, and make our teaching interesting. Therefore, "looking for beauty, discovering beauty and appreciating beauty" is what our math teachers should pursue. Especially in mathematics after the new curriculum reform, "beauty" has some external things, such as colorful illustrations, fairy-tale learning situations and dynamic mathematics courseware. These new things full of "beauty" are closer to children's lives and hearts and become the source of their happy learning. In addition to the beauty produced by these obvious changes, our mathematics teaching is also full of aesthetic feeling. What we are used to in our usual teaching is precisely the beauty. These "beauties" may require us to feel, experience, reflect and experience more.
Below I will talk about some views on how to infiltrate aesthetic education in mathematics teaching.
First, realize the beauty of mathematics from life
Mathematics comes from life. Mathematics class should not only lead children into the ocean of numbers, but also reproduce the beautiful picture of life mathematics. It is quite boring to teach mathematics only in the teaching content. Only by integrating the mathematics we want to teach into life and giving children a real life experience can the beauty of mathematics show the colors of people. After teaching for a period of time, I often say to myself, this is life! Children's mathematics learning is life, and their perception of life has made a beautiful mathematics classroom; It is the child's imagination, the child's innocence and childlike interest, and the innocent smile of the child, which has made a beautiful math class. For example, "5", I ask children to say "5" in life. Children not only have direct answers such as "hands have five fingers and a five-pointed star", but also wonderful things such as "Olympic rings" and "colorful". See how many students know! Another example is "7". In addition to the answer of "seven days a week", children can also tell beautiful legends such as "seven fairies". When I teach the knowledge of understanding objects, in the summary session, please ask the children to say what they have learned in this lesson. Children have given examples in their lives, "My TV set is a cuboid"; "My refrigerator is a cuboid"; "My toy Rubik's Cube is a cube"; "The steel bars of classroom windows are cylinders"; "My favorite football is a ball" and "the iron box of eight-treasure porridge is a cylinder"; Some students even said, "if you want to build a fence for pigs, you have to use a cube or cube of stones." If you want to use the post, you must stand up. The ball is not suitable for building a house. " "In a race of four objects, the ball will run farthest, the cylinder will definitely fall and roll with curved edges, and the cuboid and cube will run slowest ..." Although children can't tell the mathematical characteristics of the four objects strictly and completely, they can find them in life, and even use them to "build houses and race". What a vivid application, they bring what they have learned to life, and they will suddenly realize that they are living in it. They will also realize that these beautiful things in life are mathematics, there is mathematics everywhere in life, and there is beauty everywhere in mathematics.
Second, experience the beauty of mathematics from the operation
Children in primary schools are curious and active. So when I make and operate school tools, I pay great attention to guiding them to infiltrate aesthetic education. For example, if I ask my children to cut out their favorite floor plans with cardboard, I will ask them to spell out all kinds of beautiful patterns according to their own cut patterns and give them a vivid evaluation: the ducklings made by a classmate with various circles are really beautiful, just like real ones. So-and-so's rectangular, square and round robots are really impressive. It's already his good friend ... In the practice of cutting and cutting in Senior Two, I asked students to cut out different children by themselves according to the tips in the textbook. Some are side by side, and some are overhead. This paper-cutting activity is not only to cultivate students' practical ability, but more importantly, to let students learn the knowledge of "translation" and "rotation" while cutting paper. Some students' paper-cutting skills are still very high and are envied by other students. The process of students' cutting and spelling is the process of creating beauty, and the simple comments of teachers are also the process of guiding students to appreciate the beauty of mathematics.
Third, reflect on the beauty of mathematics from history.
China is a mathematics kingdom with a long history and brilliant achievements. Introducing some mathematical historical materials and mathematicians' stories to students can make them reflect on the beauty of mathematics and cultivate their beautiful sentiment of loving the motherland. For example, I ask students to collect information by themselves when generating teaching numbers. During the class exchange, the students reported their collection results in groups. Some groups have data to tell, and some groups have found many corresponding pictures from the Internet. Some groups collect ancient counting methods in China, while others collect foreign counting methods. Through communication, students understand that the birth of every number embodies the collective wisdom and creation of human beings, which is a history of mathematical development and a poem of human beings' constant pursuit of beauty! Mathematicians include Liu Hui, Zu Chongzhi and Hua. They are famous for their achievements in discovering and discovering the beauty of mathematics. These are all good materials for educating students about the beauty of mathematics.
Fourthly, we can appreciate the beauty of mathematics from writing.
The beauty of simplicity, fluency and clarity is everywhere in mathematics. There are concise and beautiful images in mathematical symbols, clear and beautiful charm in neat mathematical formulas, and smooth and beautiful notes in mathematical charts. In mathematics teaching, guide students to experience the beauty of mathematical forms themselves. When writing, I let my children write seemingly simple mathematical symbols with enthusiasm and educate them to "write as they are", and so do mathematical symbols. Even if children do exercises, I ask their writing and format to be neat, tidy and serious. In order to improve children's writing, I often post excellent homework in class for children's reference and imitation. Based on the above requirements, every student's writing has made great progress, and a serious and neat homework is the best way to show the beauty of mathematical format. It can also help children develop serious and meticulous habits and experience the charm of mathematical beauty.
Beauty is everywhere. Numbers, symbols, formulas, formulas, graphs, tables, equations, problem-solving methods and ideas in mathematics are all beautiful. It is not only a subject, but also a carrier of beauty, infecting and enlightening students' hearts. Let children have a better personality and know how to care and pay attention to a colorful life. Let every teacher embark on the journey of discovering beauty, not only let our math class become the source of discovering beauty for teachers and students, but also let our education become the myth of beauty to infect every child's heart, so that they can learn beauty in mathematics and thrive in the education of beauty.
