First, the application of new media technology makes primary school students' reading comprehension more intuitive.
Primary school math teachers and parents use new media to influence pupils' understanding of math reading ability and improve pupils' multiple math reading ability to adapt to the new media era. With the help of new media, language and characters can show students vivid life scenes, thus reducing the difficulty of understanding life language and reducing the differences in understanding life language. For example, children line up for school. Xiaoming has two children in front and two children in the back. How many children are there in Xiaoming's team? It is really difficult for freshmen to understand the meaning of this question. But with the help of multimedia, children can easily understand the meaning of this problem, which can be transformed into mathematical language and solved. With the help of PPT software, the teacher makes courseware of corresponding life scenes, and it is not so difficult for students to understand him
Without the help of multimedia, the ambiguity that children understand is mostly "people in front+people behind = this group of people". But through multimedia, life scenes can be restored, and it is not difficult for children to understand: people in front+people in the middle+people behind = the number of Xiaoming's team. Thus, the abstract language of life is transformed into a mathematical language with mathematical relations.
It is not too difficult to understand "as much", but it is still difficult to distinguish between left and right with children in Grade One. Teachers can distinguish left and right together with children through the multimedia display platform, and then write "left" and "right" on each group of pictures respectively, so that students can distinguish left and right more intuitively. So as to understand the meaning of this question and improve the reading ability of mathematics.
Second, the comprehensive application of new media has reduced many obstacles for students' mathematics reading.
New media is widely used in life. How can teachers make courseware by using various new media to improve teaching efficiency? For example, we can use the camera function of smart phone to take pictures of the required materials, and then use the editing function of QQ to cut out the appropriate pictures, insert them into PPT, edit the appropriate words, and arrange them in a certain order, so that we can make corresponding courseware, or we can use the Internet to find the courseware we need, improve it and change it into the courseware that suits our needs.
Third, the use of new media to form, develop and improve students' mathematical literacy.
"Learning is expensive and doubtful, small doubts and small progress, big doubts and great progress". The use of new media enables students to obtain useful mathematical information, master relevant mathematical knowledge and methods, solve mathematical problems and understand mathematical ideas. Including students' ability to collect and sort out information, analyze and identify information, find problems, ask questions, analyze and solve problems according to information, and share information. (As shown on the left) After reading the pictures, children can collect, sort out and analyze the information provided by the pictures, and then find problems, ask questions and solve problems according to the information: 1+ 1=? 2+ 1=? 3+4=? 3+5=? 4+5=? 4-3=? 5-3=? ... the information capacity and trained thinking contained in this question are unimaginable in ordinary teaching, and the potential of children is unimaginable. So as to stimulate primary school students' interest in mathematics reading, form good mathematics reading habits, cultivate students' mathematics reading ability, and form, develop and enhance students' mathematics literacy with this as the core.
Fourth, use new media technology to help students understand some key concepts in the problem.
Use multimedia and display platforms to grasp key words to understand, such as "original". Once, there were several birds in the tree, five flew away, and there were eight left. How many birds are there in the tree? Through multimedia presentation, let students think about the original meaning here and ask a key question, "When is the original meaning?" Let the students know that the bird is "original" before it flies away, so use multimedia to show it: Let's invite the flying bird back. Let the children understand that the original here is "the combination of the bird that didn't fly and the bird that flew away is the original bird", so as to understand this problem, it needs to be calculated by addition. Then, by analogy, give several similar examples. For example, the number of people who got off the bus and the number of people who stayed on the bus (now) add up to the original number of people on the bus, and the cabbage cut by the white rabbit and the uncut cabbage add up to the original cabbage ... Really understand the meaning of addition: combine two numbers into one number, reflecting the word "he". On the other hand, there used to be some people on the bus, but now there are 13 people after seven people get on a station. How many people are there? This "original" means no longer getting on the bus, so according to the method just now, how many people were there at that time? The conductor will let the people who have just got on the bus off, so that the original number can be counted. It is to separate the people in the car now (the sum of two numbers) and find the people in the original car, that is, to find an addend, so subtraction is needed. Similarly, we should draw inferences from others and then compare training. Subtraction embodies the word "fen", knowing the sum of two numbers, adding one to find the other number, and then understanding the concept of subtraction more accurately.
Five, the use of new media technology to promote the development of language and thinking.
Pupils should get into the habit of reading math textbooks, carefully read the questions before solving problems, and read math extracurricular books. Math newspaper for primary school students is a good choice for children, and children are encouraged to subscribe. Reading math-related topics effectively and efficiently is a necessary ability for children to develop their thinking and language in reading. For example, children are waiting in line, and Xiaohong's position is the eighth from the bottom and the sixth from the bottom. Please count how many children are waiting in line on Monday. In the process of reading, children are prone to ambiguity: ordinal number+reciprocal = queue number. Through multimedia, when counting forward, it flashes or jumps when counting to Xiaohong, and when counting backward to Xiaohong, it is known that Xiaohong has been counted twice (Xiaohong has been counted once), so "forward number+countdown-1= queue number". Another example: children line up, Xiaodong ranks sixth, Xiaoming ranks 14. How many people are there between Xiaoming and Xiaodong? Cultivate primary school students' thinking, don't use counting method, it will make children unable to start. Through multimedia, the numbers 1- 14 (fish head 1-6, fish tail 14, middle fish body and others) can be arranged and displayed by PPT, with 65438+.
In the new media era, the use of new media technology can improve primary school students' mathematical reading ability, improve the effectiveness and efficiency of primary school students' reading, develop the habit of independent reading comprehension, improve primary school students' ability to understand and recognize mathematical language, and develop language and thinking. Therefore, teachers continue to learn multimedia well and use media extensively, which is a great leap in our educational reform, a qualitative change and a happy take-off for children's learning. This is the significance of the country investing a lot of manpower, material resources and financial resources to improve the teaching environment and promote the balance of education!
