In the increasingly competitive world, information technology has become a strategic resource, which is very important to all walks of life and related to human survival and the development of social undertakings. Information technology is so important, so how can we use it correctly in teaching? If used improperly, it will also affect our classroom teaching efficiency. So everyone must understand the basic meaning of information technology and apply it correctly according to the actual situation. What is "information technology"? What impact will it have on education and teaching? Most people think that computer technology is information technology, and I think this understanding is incorrect. The latter is an important branch of the former, separated from the former, and uses advanced equipment such as computers to process and utilize information. The advantage of computer is "calculation and operation", not "analysis and thinking". As a science, information technology is not only an operational technology, but also a rigorous way of thinking in logical science, which conforms to the general law of social practice, and is not only a technology to study a certain link or stage, but also a complete process technology. Coordinated development requires not only advanced equipment, but also reasonable methods, correct systems and excellent talents. At present, most schools are equipped with advanced equipment such as computers and multimedia projectors, but due to the lack of management system, disorderly use and lack of suitable personnel operation, resources are wasted. Therefore, we should correctly understand the inherent laws of information technology and make full use of information technology in teaching practice and teaching management activities to make its application more reasonable.
Second, change the concept of education and break through the traditional teaching mode.
In the wave of educational reform, students' autonomous participation and cooperative learning are highly valued. Information technology takes multimedia technology and network technology as learning tools to provide students with rich learning resources and a relaxed and happy learning environment. Students use network technology to collect, process and communicate, explore and learn, so as to acquire knowledge. This learning mode highlights students' dominant position, emphasizes students' independent participation in learning, and truly breaks through the teaching mode of "teacher-centered, relying on teachers to speak and students to listen". The teacher just creates a teaching scene for the students, guides them to operate, and then collects relevant information according to the questions, exchanges and studies online, so as to explore the answers. In this process, teachers should first obtain teaching information by themselves through the network, so as to effectively guide students' questions in the process of collecting information, which requires teachers to master network technology first. This teaching mode is the inevitable trend of education development, and it will greatly optimize the teaching environment. In teaching, teachers change from the main body of teaching activities to the organizer, director and helper of the whole teaching process. Students gradually become active participants, explorers and executors in the learning process. Therefore, further updating the concept of education is a problem that every educator can't ignore.
Third, stimulate interest in learning and innovate the educational atmosphere.
Interest is the source of motivation to promote students' learning. "Happy learning" is the full expression of students' interest in learning and the initial beginning of mastering knowledge. "Happy learning" means giving full play to students' initiative under the concept of educating people, making students' status change from passive to active, making students' learning no longer wait and rely, but changing learning into thinking, learning into enlightenment and multimedia teaching. A large number of vivid and colorful words, charts, graphics, images, animations, sounds, movies, videos, etc. It is presented to students in an electronic, vivid and intuitive way, and scenes are created to stimulate students' interest in learning, so that students can watch and listen, deepen and accelerate their perception and understanding, highlight key points, solve difficulties, increase classroom knowledge capacity and improve teaching efficiency. Students rise from perceptual knowledge to rational knowledge. In this way, students will feel relaxed and happy in their study, master knowledge quickly and have high memory efficiency. In classroom teaching, multimedia teaching can solve many difficult problems with novel means and superb technology. It can not only provide dynamic and rich images, graphics and words, but also make the classroom a game world, vivid, intuitive and vivid, and change the boring classroom teaching. For example, when teaching the content of "surface area of cylinder", the media teaching software is applied to display a complete cylinder model on the screen, and then the side is slowly unfolded, while the cursor flashes, and then the two bottom surfaces are presented to the students in different colors, and the two bottom surfaces are completely overlapped, so that the students can immediately realize that the surface area of the cylinder is composed of three parts, and the two bottom surfaces are equal. Calculating its surface area is to calculate the sum of the areas of these three parts. Through this dynamic display, we can move those seemingly static things, let students deepen their understanding of knowledge and further deepen it, and the process of students accepting knowledge can also be shortened. The purpose of mathematics teaching is to cultivate students' thinking ability, which must be realized through practice. In practice, the process of re-understanding can be completed. The advantages of multimedia teaching can be well qualified for this work. It can not only provide intuitive images and vivid dynamic images, but also develop students' observation ability and spatial imagination. It can also induce students' happy learning mood and stimulate students' interest in active thinking through vivid image changes and beautiful music. Therefore, information technology can stimulate students' interest in learning and create an educational atmosphere.
Fourth, change the way of learning and carry out students' independent inquiry learning and group cooperative learning.
What kind of learning style is most suitable for students in classroom teaching? At present, the general view is to advocate group cooperative learning, which is conducive to cultivating students' team spirit and giving play to students' self-education. But everyone has his own observation angle and way in the process of cognition, so it is necessary to adopt independent inquiry teaching.
The first is to find information. In today's network information age, the network is the largest database. In education and teaching, we should guide students to make good use of computer networks and actively and purposefully discover information according to their own learning requirements.
The second is to analyze and study the information found. Be able to screen and identify the information you need, judge its credibility, and then classify the information that is considered true and useful.
Finally, use the information found. That is, using the information we have, using information technology or other means to analyze and solve various practical problems encountered in life and study. All this is done by computers, but at the same time, it is also a kind of learning for students to cooperate, discuss and communicate with others.
Practice shows that information technology can stimulate students' curiosity, interest in actively exploring knowledge, concentrate students' attention, cultivate students' ability of observation, discussion, analysis and thinking, effectively increase the frequency of information feedback and reduce students' academic burden. It is an educational technology that modern educators must master.
Fifth, highlight the teaching difficulties and reduce the teaching difficulties.
Proper use of the characteristics of information technology, such as concrete image, dynamic and static combination, sound and emotion, can change mathematical knowledge from abstract to concrete, mobilize the synergy of students' various senses, and learn things that teachers can't explain and students can't understand, so as to effectively realize intensive reading teaching, highlight key points, break through difficulties and reduce teaching difficulty. Examples, explanations, reasoning, proofs, etc. The materials in mathematics textbooks are static, and it is difficult for students to understand and stimulate their subjective participation consciousness only by abstract language description. According to students' cognitive characteristics, using information technology to make static knowledge dynamic and abstract knowledge concrete is conducive to creating a positive learning environment, cultivating students' divergent thinking and creatively solving problems. Teachers can use courseware to present the complicated process in the textbook, so that students can have an intuitive understanding, thus breaking through the difficulties, making the content that is very difficult to teach easy for students to accept, showing strong vitality.
For example, in explaining the lesson of "area of a circle", in order to let students better understand and master the key point of calculating the area of a circle, the author first draws a circle on the computer, then divides the circle into two equal parts *** 16, and then interlaces the two parts through animation, so that an approximate rectangle can be made. Repeat the demonstration several times, so that students can feel and finally realize that the area of this approximate rectangle is completely equal to the original circular area. You can also ask the students: What else did you find? What is the relationship between the length and width of this approximate rectangle and the circle? Thus, the area formula of the circle is deduced. The application of information technology can easily break through the key points and difficulties of this course, and also reduce the difficulty of teaching, which has achieved good teaching results.
Sixth, improve students' reading and writing ability.
Multimedia technology integrates many functions such as sound, image, text and animation, and has the characteristics and advantages of intuitive image, vivid color, realistic sound and combination of motion and static. In the previous composition teaching, the teacher gave a composition topic or a piece of material, and the students sat down to ponder, which was difficult to inspire and had poor effect. The application of information technology or colorful network resources in composition teaching effectively alleviates this contradiction. Teachers can collect and sort out relevant materials such as words, images and sounds related to the theme of this section of composition training before class, and make boring materials and topics concrete, vivid and vivid, making them have strong appeal, enabling students to mobilize various senses to know the world, absorb various nutrients from them, and constantly improve and enrich their composition "material library", thus further stimulating their interest in writing and laying a foundation for writing.
.
Modern information technology is a powerful tool for students to learn knowledge and solve problems. Computers and networks will become an important means to cultivate students' understanding and interest. Students can obtain information through various modern media to help them think and promote their study. As an operational exploration tool, modern information technology can not only effectively promote the development of students' innovative spirit, but also help students get rid of some tedious, boring and repetitive studies. Students can operate and talk to the computer, learn from each other and communicate with each other, so that they have more opportunities to start work, use their brains, think and explore, fully mobilize students' learning initiative, cultivate students' awareness of cooperative inquiry, reduce students' academic burden and improve learning efficiency.
In a word, computer-aided teaching has inserted a pair of powerful wings into students' thinking, allowing students' innovative thinking to fly freely in the classroom, which is an irresistible teaching method for modern educators. In education and teaching, only by facing difficulties, constantly exploring and researching, paying attention to actual results and optimizing integration can we keep up with the pace of the times, give full play to the advantages of computer network-assisted teaching, truly implement quality education and make the development of education more brilliant.
