The extensive application of modern information technology is profoundly affecting the content of mathematics courses, mathematics teaching and mathematics learning. In mathematics teaching, make full use of information technology, integrate pictures, texts, sounds and images, make teaching activities more colorful, make mathematics classroom teaching no longer boring, create many interesting scenes for students, expose them to more mathematics knowledge, broaden their horizons and satisfy their strong thirst for knowledge. It can not only stimulate students' interest in learning, cultivate students' skills, but also develop students' intelligence, so as to obtain the best teaching effect. Therefore, it is of great practical significance to advocate and explore the application of information technology in mathematics teaching under the background of actively promoting educational modernization and informatization in China, so as to make complex and abstract mathematical concepts vivid, thus developing students' information literacy and cultivating students' innovative spirit and practical ability. Teachers should be good at studying how to use modern information technology for effective teaching from the perspective of their own disciplines, and be good at integrating modern information technology into primary school mathematics teaching-just like using blackboards, chalk, paper and pens to make teaching and learning efficient.
First, the specific application of information technology in mathematics teaching
(1) The application of information technology can stimulate students' interest in learning.
As the saying goes, "Interest is the best teacher". Stimulating students' interest in learning and making them willing to learn can maximize students' subjective initiative. One of the reasons why students are bored, boring and afraid of learning mathematics is that the abstract and rigorous mathematical knowledge itself, and the limitations of traditional teaching means and methods can not effectively stimulate students' interest in learning. Interest is the driving force of learning, the beginning of acquiring knowledge and the basis of curiosity. In the early school age, junior high school students' learning motivation is often influenced by their interest in learning. Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy". Psychological research shows that interest plays a great role in human development and social life. It leads people into a colorful world, and the characteristics of various things arouse people's curiosity, attract attention, and urge people to explore and know, thus increasing knowledge, developing intelligence and loving life. As far as mathematics teaching is concerned, the teaching effect will be better only if students are interested in learning content and homework. Therefore, carefully creating situations in the classroom lead-in, starting with stimulating students' interest in learning, and striving to stimulate students' curiosity and thirst for knowledge can enable students to actively acquire knowledge driven by interest. Multimedia, a modern educational technology, just adapts to children's psychological characteristics. It can change the shape, sound, color, movement and stillness, show students concrete, vivid and intuitive audio-visual materials, and fully mobilize students' multiple senses to participate in learning.
In the teaching environment of information technology, the presentation of teaching information is stereoscopic, rich, vivid and interesting! There are not only transformations of numbers, but also some transformations of shapes. Using multimedia technology and flash software, the geometric model is displayed, and the image is translated, flipped and unfolded, which makes complex mathematical problems concrete and simplified. At the same time, it shows students the beauty of symmetry, harmony and curve in mathematics, so that students can appreciate the infinite scenery in mathematics learning and stimulate their interest in inquiry learning. For example, when teaching the content of "translation and rotation" in the fifth grade of primary school mathematics in the new century, I first organize students to observe the translation, symmetry and rotation patterns in real life, and then let the children talk about how these patterns are translated, symmetrical and rotated. What are their characteristics? On this basis, I arranged for students to use computers for pattern design. This is a good opportunity for students to use modern means to carry out creative activities! If students are required to design on square paper, some graphics are not easy to make, which will affect the beauty of the patterns. But if you put it on a computer, you can start with a simple figure, make it symmetrical, translate and rotate several times, get a series of new figures and form patterns. Open topics give students great room for imagination and development, and they can roam freely in a free and relaxed world. Finally, through the networking of students' computers, we can collectively appreciate students' works, feel the beauty of patterns, experience the endless changes of geometric shapes and enjoy the fun brought by mathematics!
(B) information technology to cultivate students' application awareness and practical ability, and expand students' horizons.
Teaching should reflect the ins and outs of knowledge, properly introduce the relationship between mathematics content and daily life of other disciplines, and guide students to use mathematics to solve some practical problems by themselves through activities such as mathematics practice, experiment and research study, so as to broaden their horizons and increase their knowledge. Information technology can help people build models of problems in the process of collecting, sorting, describing, exploring and creating, and make correct judgments by studying the models to solve related problems, which provides a very effective, simple and cheap means for people to exchange information. Information technology network resources are the extension of classroom teaching. No matter in time or space, it has left us a broad space for development. Making good use of it will definitely make a qualitative leap in traditional classroom teaching. For example, after learning PI, students searched online for knowledge about Zu Chongzhi and PI, and they were full of interest, only then did they know that the world was big and colorful, and they were influenced by beauty, which further inspired their confidence and determination to study hard and be determined to succeed.
Information technology education has created a networked learning environment for students, which has greatly changed their learning concepts, and students can conduct "independent discovery and independent exploration" learning. The website stores a lot of learning information, exercises, troubleshooting and so on. Every student can choose purposeful study according to his knowledge level and interest. This greatly stimulates students' interest in learning and plays an important role in cultivating students' creative thinking development and innovative spirit. (3) Information technology helps students to explore independently and improve their cooperative learning ability.
Mathematics learning activities need to be carried out with certain methods and tools. The application of every new technology will provide students with more learning space. Modern information technology can help students explore the formation process of mathematical knowledge rules independently, thus making students' learning change from "passive acceptance" to "active exploration". It is precisely because of this change that students become the real beneficiaries of learning and the real masters of learning. The new curriculum standard points out in the teaching suggestion that the process of mathematics learning is full of exploratory and challenging activities such as observation, experiment, simulation and reasoning. Teachers should change the teaching methods based on examples, demonstrations and explanations, and guide students to actively participate in exploration and exchange learning activities. In students' exploration and communication, modern information technology can help students show their learning process and results. While individual students gain successful experience, all students can enjoy the learning results and communicate on an equal footing. Learn to communicate and cooperate and learn to learn. Classroom teaching is the main channel to implement quality education. Proper use of modern information technology can stimulate students' interest in learning, turn abstract into concrete, turn boring into vivid, greatly mobilize students' enthusiasm for learning, attract students to actively participate in the learning process, and cultivate students' creative thinking and hands-on operation ability. For example, when learning the knowledge of "straight line, ray and angle", on the basis of independent thinking, hands-on operation and group communication, students use videos to show all students the exploration process and learning results of themselves and the study group. In the process of presentation, students show the value of learning individuals, learn to listen to other people's opinions, and regard other people's research results as part of their own learning. Get the successful experience of independent thinking, self-presentation, cooperation and communication. Change ideas and methods. In the process of this change, teachers' teaching and students' learning are organically combined, and the efficiency of classroom teaching will continue to improve, which also brings new opportunities for education and teaching reform.
(d) Developing students' thinking with the help of information technology and making their thinking "visible".
Mathematical concepts and formulas are highly abstract and rigorous, while primary school students mainly think in images. If teachers only explain in order to make students understand knowledge in teaching, it will be boring and uninteresting. Secondly, it is difficult for students to understand, even if they remember, they just memorize and don't understand knowledge at all. Computer-aided instruction can provide vivid perceptual materials for primary school mathematics teaching process, pave the way for students to build bridges, let students participate in them, help students observe and compare, and gradually master the essence of knowledge, so that students can better understand and understand mathematical concepts, laws and rules. Appropriate use of computer courseware to assist teaching and turn abstraction into image is not only easy for students to watch, but also easy to understand, so as to better complete the learning task. Therefore, with the help of multimedia, it not only enriches students' perceptual knowledge, but also reveals the essential laws of mathematical knowledge, thus simplifying the complex, making the difficult easy and enlightening students' thinking.
Second, the practical thinking of the application of information technology in mathematics teaching
Computer technology makes mathematics classroom teaching no longer boring, creates many interesting scenes for students, exposes students to more mathematics knowledge, broadens students' horizons, satisfies their strong desire for knowledge, and lets them see a colorful world of mathematics, so that they are no longer limited to what teachers say and classes. But everything has two sides. Traditional teaching and modern educational technology have their own advantages and disadvantages, so we should choose them reasonably and not go from one extreme to the other. I think that when applying modern information technology to mathematics classroom teaching, we should pay attention to the following questions:
(A) the use of modern teaching media should retain the tradition and inherit the intuitive teaching of "doing".
With modern educational technology, we can't abandon the traditional teaching methods. Primary school students' mathematics learning is an empirical learning to a great extent, and the acquisition of experience is mostly realized through personal practice. Without the accumulation of a lot of direct experience, perception becomes a scratch, and representation cannot be established in the brain. For example, the teaching of "Knowledge of Kilogram" requires students to perceive the weight of 1 kg in large quantities, so that students can learn through various operational activities such as weighing, weighing, comparing, watching and calculating.
(2) The application of information technology should serve teaching.
The computer is a teaching tool just like the blackboard, and the application of information technology is only a teaching means, not a new thing to show off. Multimedia technology shows students more vivid thinking and stimulates their vision and hearing. However, over-reliance on multimedia technology or unscientific use of multimedia will make students feel lazy and is not conducive to the cultivation of students' abstract thinking ability. Flashy courseware can not only optimize classroom teaching, but also distract students' attention. For example, a teacher set a lot of oral calculation questions on the courseware of "Addition and subtraction within 100" in senior one, and each question has a beautiful pattern background. Clicking on it will also generate sound and display the answer in the form of animation. This kind of training is easy to distract students' attention, cause visual interference and cause visual fatigue, and fail to achieve the training purpose. Therefore, before using information technology, teachers should make clear the advantages and disadvantages of information technology, the characteristics of teaching materials and students, and the needs of subject teaching, and strive to find out where information technology can improve the learning effect, so that students can complete things that cannot be done by other methods or have poor results. As a modern auxiliary teaching method, information technology is used to support teaching work, improve classroom teaching efficiency, break through key and difficult points, mainly make up for the shortcomings of traditional teaching and solve problems that traditional teaching is difficult to solve. Rather than the only teaching method, beautiful courseware is not a good courseware, but depends on whether this courseware helps to expand students' thinking, whether it is conducive to students' active learning, and whether it helps students break through key and difficult problems. (C), the use of information technology should pay attention to practicality
The application of information technology in teaching is only a means, the purpose is to better complete the teaching task. We are using information.
Technically, we should proceed from the teaching content and determine the form according to the content. First of all, we should consider the practicality of teaching, and then consider the practicality of life and the aesthetics of courseware on the basis of practicality, instead of making the courseware too fancy, otherwise it will distract students and affect the teaching effect. The advantages of traditional teaching, such as timely communication between teachers and students and active atmosphere for organizing and discussing problems, are irreplaceable by any modern tool. In traditional teaching, when the teacher writes the key content on the blackboard, that is, when the students examine and think, the key content can always be preserved. Blind use of information technology does not leave enough time for students to think. On the surface, the whole class takes the initiative, and teachers and students cooperate and coordinate, so that students become the main body. In fact, after class, most students' minds are full of lively scenes in class, which can't meet the requirements of accepting knowledge. The combination of information technology and primary school mathematics classroom teaching has undoubtedly injected new vitality into traditional mathematics teaching. Teachers use modern multimedia information technology to creatively design teaching activities and give full play to the unique function of computer-aided teaching, which can make the teaching form more vivid, diversified and visualized, help fully reveal the formation and development of mathematical concepts, the process and essence of mathematical thinking, show the formation process of mathematical thinking, and make mathematics classroom teaching more effective. In a word, choosing the best combination of information technology in mathematics classroom teaching, using multimedia in a timely and appropriate manner and exerting its maximum effect can reduce students' learning burden, improve classroom teaching efficiency, promote the implementation of quality education and effectively cultivate creative talents, which meets the needs of modern education. The combination of information technology and primary school mathematics classroom teaching has undoubtedly injected new vitality into traditional mathematics teaching. Teachers use modern multimedia information technology to creatively design teaching activities and give full play to the unique function of computer-aided teaching, which can make the teaching form more vivid, diversified and visualized, help fully reveal the formation and development of mathematical concepts, the process and essence of mathematical thinking, show the formation process of mathematical thinking, and make mathematics classroom teaching more effective. Learning is easy because of the mouse, and life is wonderful because of the Internet. Information technology has injected great vitality into mathematics teaching. With the improvement of teachers' information technology level, teachers' awareness of using modern educational technology and modern educational concepts will also be improved, and the efficiency of classroom teaching will also be improved in an all-round way. Change the traditional teaching mode and promote the process of basic education reform.
