An obvious advantage of modern technology is the diversity of educational information display (text, graphics, images, sounds, colors, animations, etc.). ), vivid and novel, can create diversified external stimuli and provide good conditions for cultivating students' creative spirit and innovative thinking. Therefore, make full use of the advantages of information technology, such as large capacity, many interests and high efficiency, and fully mobilize students' various senses by using the characteristics of multimedia with pictures and pictures, so that students can immerse themselves in the scene and study in the best state.
In addition, using modern information technology to create suspense in mathematics classroom teaching can guide students to explore problems. Creating rich teaching scenes for students, adding questions and setting suspense skillfully are easy to stimulate students' thirst for knowledge. For example, "connect the midpoints of four sides of a quadrilateral in turn, and ask what kind of quadrilateral can be enclosed?" For this problem, a dynamic quadrilateral can be displayed with a geometric sketchpad, so that the shape of the quadrilateral can be changed at will, and the shape of the quadrilateral surrounded by the midpoint can also be changed, so as to guide students to explore which properties of the original quadrilateral determine the shape of the quadrilateral with the midpoint, thus leaving more time and space for students to think, so that students can solve new problems, discover new problems or ask new questions on the basis of existing knowledge.
Second, use Powerpoint, Flash, geometric sketchpad and other software to make courseware to visualize abstract things.
Mathematics itself is very abstract, and some models involved and their changing processes are also very abstract, so the learning of abstract concept rules often cannot flexibly adapt to the changes of specific situations. Therefore, situational learning has been paid attention to, and information technology can create conditions for students to realize situational activities of learning objects, so that students can get an immersive feeling in the classroom. Take the three views in solid geometry as an example. When students first come into contact with space geometry, it is difficult to imagine the projection of objects on all sides and their relationship, and it is also difficult for teachers to draw clearly on the blackboard. Therefore, drawing three views of an object with the help of the geometric sketchpad vividly shows the drawing rules to students, so that students can master them more thoroughly. On the contrary, the advantages of computer-aided teaching are obvious by imagining three-dimensional graphics through three views. For another example, in the math activity class "decoration bidding", the teacher first shows the students a virtual reality situation, a room that needs decoration, and describes it in language: "As long as you set a reasonable budget, the room will be decorated and show you who won the bid." Then, students gradually realize this in fictional situations. First, they check the data of room layout, calculate the area of the room by measuring the length, width and height, then investigate the building materials and collect information. This virtual scene, building materials market, is really enjoyable, the introduction and price of composite floor, carpet and solid wood floor. Students can choose according to their own preferences, choose a good redesign scheme, budget funds, and finally bid for evaluation to show the effect.
This combination of information technology and mathematics teaching creates a virtual reality for students. Relying on resources, through search, communication, cooperation and filling, students' dominant position is highlighted, so that learners are immersed in it and the learning effect is enhanced.
Third, show the dynamic formation process of things and let students experience the process of change.
The content of mathematics teaching is sometimes abstract. In the process of teaching, whether teachers can handle the teaching materials reasonably is also an important factor affecting the teaching effect. Among them, how to highlight the key points and break through the difficult points is a difficult problem in teaching. Multimedia technology has become a means for teachers to highlight key points and break through difficulties in teaching. It can turn static into dynamic, highlight key points and dynamically show the process of knowledge formation. Computer-aided can change the traditional "static demonstration" into an intuitive and vivid "dynamic demonstration", fully display the parts that are not easy to display in real objects, help students strengthen their perception, enrich their appearances, make abstract knowledge easy to understand and achieve ideal teaching results. The concept of pyramid frustum in the new textbook is defined by how it came into being, which embodies a dynamic process. This process can be easily displayed by using the geometric sketchpad, which is intuitive, improves students' interest and strengthens their understanding of concepts, which is incomparable to how beautiful the language is.
Fourthly, the application of modern information technology in mathematics classroom teaching can provide rich resources for mathematics teaching.
Mathematics curriculum standard points out that the content of mathematics learning should be realistic, meaningful and challenging. The introduction and wide application of information technology has undoubtedly injected fresh water into mathematics teaching, and its integration with mathematics teaching methods has greatly broken through the limitation that books are the only learning resources and provided students with rich teaching resources. On the other hand, expand the teaching knowledge to the maximum extent, enrich the closed and isolated classroom by using various related resources, and let students jump out of the limitation of learning only the contents of textbooks, thus broadening their horizons and diverging their thinking.
Information technology has the characteristics of integrating text, image, sound, animation and other information carriers. It can make use of the unique advantages of visual and auditory effects to provide students with rich resources, which is far more attractive and infectious than monotonous teaching methods.
Fifth, the application of modern information technology in mathematics classroom teaching is conducive to activating students' thinking and cultivating students' innovative consciousness.
A philosopher has a famous saying: "Nothing can be replaced, only thinking can't." Mathematics teaching is the teaching of thinking, and it is an important way to cultivate students' creative thinking to let students actively participate in learning and dare to guess and question. Therefore, in teaching, teachers should pay attention to the cultivation of thinking ability, guide students to be good at finding problems, asking questions and solving problems by themselves, and cultivate students' innovative spirit. In mathematics classroom teaching, with the help of multimedia technology, we can create various scenarios that are suitable for the teaching content, construct problems on students' rich life background, expand students' horizons of exploring mathematics, provide students with exploration opportunities to understand mathematics ideas from multiple angles, activate classroom thinking and cultivate students' innovative consciousness. For example, some scenes in life are recorded or teaching-related materials are stored in the computer in the form of multimedia. When teaching, the clips suitable for the teaching content are selected as problem scenes to be played in the classroom, so as to attract students to actively participate in exploration activities, participate in the process of problem discovery and problem analysis, and let students learn mathematics in an interesting atmosphere.
Modern educational technology has the advantage of storing teaching information in large capacity. It can cross the boundaries of time and space, provide students with a large number of rich learning materials, and help to cultivate students' ability to explore and solve problems by using resources. In this inquiry process, it will not only help students to construct the meaning of knowledge, improve their understanding level, but also explore their creative potential.
Sixth, the application of modern information technology in mathematics classroom teaching can feed back information to students faster and stimulate their learning motivation.
In terms of feedback, the combination class of mathematics and information technology has more advantages than the ordinary class of mathematics. For example, in the division teaching with remainder, the computer can give students timely feedback on correct and wrong evaluation, tips, guidance, suggestions and other information. Displaying students' different problem-solving processes on the screen through the Internet can not only enable students to quickly understand their own learning situation and deepen their learning experience, but also enable teachers to obtain teaching feedback information from them and take remedial measures in time to make the teaching process close to the teaching objectives, thus realizing real hierarchical teaching and personalized teaching. Not only that, teachers can also use the advantage of computer timely feedback to stimulate students' desire to pursue success and let students experience and enjoy the happiness of success. In teaching, the computer will feedback students' learning situation in time, such as filling in the blanks, judging and selecting topics. If the student answers correctly, the computer can immediately display the answer and praise the student. "You're great" and "you're really smart" ... After reading and listening, the students are naturally happy and their interest is stimulated. If the students answer wrong, the computer will remind them with music: "Think again", "Study hard", "Come on" and so on. This will not only enable students to know their learning situation in time, but also encourage them to use their brains seriously and develop a rigorous learning attitude.
Seven, the application of modern information technology in mathematics classroom teaching can realize student-oriented and give students the initiative in learning.
The core of the so-called "combination with teaching methods" is to integrate modern educational technology into mathematics teaching. In teaching practice, multi-dimensional information such as words, images, sounds, animations, videos and even three-dimensional virtual reality is obtained through technical means to make courseware, which enriches the teaching capacity and content, and the teaching methods used are more diversified and flexible. Combination means not simply superimposing information technology as a teaching method with traditional teaching methods, not simply projecting with a few slides and an object, but making information technology really serve teaching and realize the interaction of students' learning process.
Before class, teachers should analyze and process the teaching materials according to the teaching objectives and present them to students in the form of courseware or web pages. In class, after students accept the learning task, they organize three groups to collect materials, sort out and analyze the data. Under the guidance of teachers, they use the information provided by teachers (or search for information by themselves) to carry out independent learning combining personalization and collaboration, and use information technology to complete tasks-they have experienced the process of collecting data, learned to organize data, and can effectively analyze data. Finally, teachers and students evaluate and give feedback together.
Eight, the application of modern information technology in mathematics classroom teaching is conducive to cultivating students' information literacy and enabling students to master the learning methods in the information age.
Enable students to have the ability of lifelong learning.
"Information literacy" is the core element of quality education and a part of people's overall literacy in the information society. Information literacy education is related to how people base themselves on the information society. Mathematics classroom teaching also plays the role of "main channel" and "main position" in cultivating students' information literacy. Therefore, teachers should be good at integrating the consciousness of cultivating students' information literacy into mathematics classroom teaching activities, so that students can be influenced by information knowledge from an early age. For example, in the teaching of "tax issues", students can search the website of tax consultation online, and they can explore in the form of cooperative dialogue on the website according to their hobbies, learn the calculation methods of various benefits-taxes and fees, and understand various tax policies.
It can be seen that information technology provides a powerful tool for mathematics teaching and brings new vitality to mathematics teaching. As a combination of cognitive tools and mathematics curriculum, information technology will undoubtedly be the dominant learning mode of mathematics curriculum in the information age, and it will also become the main method of mathematics education and teaching in schools.
