On the Application of Information Technology in Mathematics Course
Information technology as a discipline, a tool introduced into education, has driven profound changes in education in terms of purpose, content, method and organizational form. The integration of information technology with various disciplines is the key and core of information technology applied to education. The integration of information technology and mathematics curriculum is to take mathematics as a carrier, organically combine information technology and mathematics teaching, and use it as a tool to acquire knowledge, change the traditional mathematical model, improve the effect of teaching and learning, and improve teaching and learning. s efficiency. Therefore, I think that if we want to be good at work, we must first sharpen it. Modern education must make full use of information technology to make it serve the primary school mathematics education.
One, The combination of information technology and mathematical content
The introduction and widespread application of information technology is undoubtedly infused into the living waters of the times, and it contains vast teaching resources. The use of the Internet platform can provide students with abundant resources, which can greatly break through the limitation of books as the only learning resource, maximize the amount of teaching knowledge, and enable students to jump out of the limitations of studying only textbook content. Thereby, we can broaden our horizons, diverge our thinking, listen to the words of 100 schools, and realize the thoughts of 100 schools.
For example, when teaching "Simple Statistics", students can use the free time to understand the statistics and bar charts through the Internet. After the group discussion in class, ask a classmate to speak: What do you know through online inquiry? What more questions? And use the drawing tools to make the bar statistical graphs by themselves, so that students can find prototypes of mathematical knowledge from familiar real life, rely on students 'interest in emotional materials, and stimulate students' thirst for knowledge.
Another example is when teaching "Reading and Writing in Numbers", arrange for students to collect a set of favorite data through their favorite channels, such as surfing the Internet, referencing books, and asking questions. Please ask each group to recommend one Classmates report. The data they reported are: the length of the Yangtze River and the Yellow River, the height of Mount Everest, the width of China ’s land area, the number of Chinese population, the growth rate of the national economy, etc .. Data not only surpassed the knowledge in textbooks, expanded the knowledge, and successfully completed teaching tasks, but also implied a moral education penetration for students.
In teaching, it is the characteristics of using information resources to cross time boundaries and organically combining information technology and teaching content to make teaching content more colorful, closer to life and more characteristic of the times. At the same time, teachers have changed traditional concepts. , Give the teaching content a new meaning, make the teaching content alive.
Combination of Information Technology and Teaching Form
First of all, it greatly stimulates students' interest in learning. Einstein said: "Interest is the best teacher." Without interest, the activities of student subjects will be marginal. How to guide students' yearning for mathematics in primary school mathematics teaching activities and get happiness and enjoyment from it. However, interest and motivation are caused by the novelty and uniqueness of external things, especially for elementary school students. Modern information technology in classroom teaching is a carrier of teaching information and a tool for transmitting information. It can not only be used to transfer teaching content, but also change the traditional teaching methods and learning methods, regulate the classroom atmosphere, and help create a good learning environment. Stimulate students' interest in learning.
For example, in the class of "Circle Area", the traditional teaching was done by teachers using language descriptions. The students only perceptually knew the relationship between the pi and radius, but they did not understand the area of the circle. Reduced student interest in learning. The integrated teaching of information technology and disciplines overcomes this shortcoming: I first make a circle, then gradually fill it with animation, and vividly show the area of the circle to the students. The students understand the process of the presentation and improve the students' Learning interest. After using information technology to teach, students ’interest in learning is increasing day by day, their attention in the classroom is obviously improved, and feedback on teaching information is more positive, which enhances the initiative of learning, no longer takes learning as a burden, and likes to learn mathematics more than ever Make mathematics one of their favorite subjects.
Secondly, it effectively broke the teaching focus. Elementary school students have strong memory skills but poor understanding skills. If our classroom teaching is only content to allow students to "remember" some knowledge points, and not pay attention to whether they really grasp its true connotation, students will only know it but do not know why, especially for the more abstract learning content . While using conventional teaching methods, we appropriately use modern information technology and dynamic image presentation technology to make use of the richness, vividness, and vividness of media information dissemination to display relatively abstract knowledge intuitively, with its strong stimulation. Role to help students understand the essential attributes of the knowledge they have learned, and promote them to understand the process of relatively complete knowledge formation.
Third, help students improve their understanding and memory. Due to the characteristics of physical and mental development, elementary school students react quickly and be impressed by dynamic objects. Computer-assisted instruction can take advantage of the organic combination of moving and still images in the teaching process. According to the content of teaching materials and teaching needs, turn static into dynamic, and combine static and dynamic to make static knowledge dynamic. In specific operations, you can use freeze, slow, acceleration, repetition and other means to add, delete, change, adjust, and teach according to your aptitude. Younger students have an advantage in mechanical memory and figurative thinking, mainly showing moving images. Senior students have strong ability of abstract thinking and intentional memory. They are no longer satisfied with providing only visual and dynamic materials. It should appropriately add some inductive and abstract images in order to promote different ages and different learning. Students in all situations can analyze and solve problems proactively.
Finally, cultivate students' sense of innovation. Cooperative inquiry teaching of primary school mathematics using multimedia means will help to create an atmosphere of innovation, encourage students to explore boldly, communicate through multiple channels, stimulate students 'desire for innovation, and cultivate students' innovative consciousness. For example, when teaching "the area of parallelograms", the teacher divides the students into several cooperative inquiry groups, so that students in each group can boldly cut and fight creatively, and answer the teacher's question: how does the area of parallelograms occur? Variety? The representatives then exchanged the results on the video display. In this process, the students' individual thinking is unprecedentedly active, inspiring each other, enhancing the sense of innovation, and having different spellings, there are different answers.
In short, the organic combination of information technology and mathematics teaching is a new teaching method in the reform of mathematics teaching. The combination of audio-visual, hand-eye combination, and the inherent appeal of its simulation, feedback, and games has great appeal. Modern information technology has been used more and more widely in teaching. The rational use of multimedia plays an irreplaceable role in primary school mathematics teaching.
Finally, I hope that teachers can make new progress in the exploration of modern education technology and make new contributions to the new round of education reform.
