Modern information technology has created favorable conditions for building a new educational model, which is conducive to cultivating and improving students' independent inquiry and interactive learning ability. Due to the rapid development of science and technology, the media used in education has also developed rapidly, and the emergence of computer multimedia technology is a qualitative leap in the history of teaching media development. Computer-based multimedia teaching system has great advantages in cultivating and improving students' autonomous learning ability in teaching rules, teaching modes, teaching contents and teaching means. In the multimedia network teaching environment, the function and structure of the school will change accordingly, creating favorable conditions for better cultivating students' autonomous learning ability.
First, let intelligence develop in "strangeness"
"Curiosity" means that the teaching content, teaching means and methods taught by teachers are constantly changing, which makes students feel novel, exciting, interesting and infatuated, thus attracting students' unintentional attention. Children are curious and will be attracted by novel or abnormal phenomena.
For example, according to real life, with the help of the advantages of modern media, the teaching of "knowing the circle" creates such a group of cartoon pictures, and the cartoon riding a round unicycle slowly drives out of the picture, and then drives out of a square unicycle, bumping up and down with the rhythm of music. Such vivid cartoon life pictures not only give students sensory stimulation, but also stimulate students' enthusiasm and interest from sensory stimulation. The question arises spontaneously: Why doesn't the round unicycle bump up and down? What does this have to do with the circle? And so on, with curiosity about the problem, thus generating the motivation and interest to further understand and explore the secrets of the circle.
Because primary school students are lively and eager to learn, they should pay attention to students' age characteristics and cognitive rules in teaching activities, be good at stimulating students' emotions in learning mathematics, grasp positive factors, create conditions to develop students' subjectivity in classroom teaching, encourage students to boldly question and explore through practice, make students' whole learning activities full of fun, realize their learning needs, and cultivate pioneering talents with solid mathematical foundation, strong adaptability, independent personality and creative spirit.
Second, let wisdom shine in "moving"
Classroom is for students, and educators should give students plenty of opportunities to use their brains and hands. It is an attempt in our experimental exploration to let students learn by "moving", improve mathematics learning in interesting dynamic learning, and make teaching in various subjects happy and efficient. Practice has proved that bringing mathematics back to life can make students move their eyes, brains and hands, and make the classroom full of passion and vitality, which will get twice the result with half the effort.
Students can't think without doing it. Operation is the source of intelligence and the starting point of thinking. For example, when teaching "triangle area calculation", let students take out all kinds of triangles prepared before class, cut, spell and fold them, transform them into learned figures, and deduce their calculation formulas. With the experience of deducing the area of parallelogram, the exploration of cutting and splicing and the inspiration of the teacher, we have come up with various methods. In operation, some students use "double spelling", some students use "cut spelling" and some students use "overlapping spelling". In this way, by allowing students to operate independently, not only can all students actively participate in the learning process and master new knowledge, but also they can cultivate their comprehensive ability and let their wisdom shine in action. The atmosphere of learning activities.
Through practical exploration, we deeply feel that information technology not only brings infinite happiness to students, but more importantly, it makes students feel the value of learning mathematics and realizes the goal of everyone learning valuable mathematics. As a teacher, we should correctly grasp its connotation, so that students can learn mathematics in life, feel life in learning, explore independently, study happily and live happily. Another example is the teaching of application problems. From the perspective of thinking, I design the flexibility of thinking development; Formally, according to the actual life situation, students are not presented with a single choice by means of multimedia, but they make their own choices in the face of many factors such as brand, style and price, rather than being imposed by teachers. So, based on my understanding of life, I created a problem situation that is conducive to practical activities: a student took 20 yuan money to buy stationery in Jialejia supermarket, showed pictures of stationery of various brands, prices and styles, and asked: 1. Now this classmate wants to buy a pen and two erasers. Please help him buy them and work out the price of stationery in parallel. 2. What can he buy with this 20 yuan money? Students began to use their brains to discuss and think, their enthusiasm for learning was stimulated, and their thinking was like a runaway horse. This kind of presentation is familiar and amiable, which turns abstract into concrete, provides flexibility and broadness of thinking, not only promotes students' understanding and mastery of basic knowledge, but also cultivates students' ability to screen and judge information, making boring application teaching vivid. Multimedia teaching has played a role of "moving and revitalizing" here.
Third, let knowledge grow in "happiness"
Mathematics teaching should provide students with aesthetic education beyond calculation, but it is also inseparable from the basis and tools of calculation. Especially for junior students, the calculation of simple math problems is both important and boring. At this time, I will make full use of the beauty in nature and introduce lively and interesting games into the classroom.
In the teaching of "addition and subtraction of 6", I use computer tools to write all 6 in the center of a flower, and every formula with 6 as the number is a petal. Every time students find such a formula, they will touch a petal on the flower and use the game of "How many petals will open" to help students master the addition of 6. I also use the multimedia computer to write a formula on each small animal, so that children can find a good friend for each small animal and learn the addition and subtraction of 6 with the game of "finding friends": I am still teaching and designing a fruit tree, which is full of fruits, and each fruit has a formula, requiring students to practice calculation with the game of "picking fruits". The game is lively and interesting, and is deeply loved by students. By using mathematics knowledge flexibly, students can feel relaxed and happy in their studies, take the initiative to enter the classroom, and love happy math classes more.
