Please talk specifically about the principles of using information technology in art teaching.

Due to the wide application of information technology in teaching, the collection of teaching materials, the formation of teaching process and the method of students mastering knowledge have all undergone qualitative changes, especially the art teaching has benefited the most. Art is a plastic and visual art, and every class can't be separated from concrete visible images. The visual effect of images directly affects the quality of classroom teaching. The rational use of information technology not only broadens students' horizons and improves their aesthetic quality and thinking ability, but also provides a reliable and feasible material basis for cultivating students' innovative consciousness and promoting their all-round development. The following is my own opinion, for your reference only.

First of all, information technology greatly facilitates the collection of teaching resources and student information.

(1) When preparing lessons, teachers pay attention to preparing textbooks, while students pay attention to preparing lessons. It is irresponsible for teaching and students to apply the method of preparing lessons without content. At this stage, network search and the refining of related CD-ROM content create convenient and accurate resource collection conditions for teachers. For example, when I was teaching "Riding the Wind and Waves", in order to understand the development history and types of ships, I not only consulted relevant books, but also clicked on the pictures on the teaching CD. More importantly, I collected pictures, videos and other information about the historical knowledge and types of ships on the Internet. Rich information resources have filled my shallow understanding of the ship as the main means of transportation on water with a long history. Finally, the selected materials are matched with background music, explanations and text prompts, which not only enriches the teaching content, but also improves the teaching quality.

As for the relevant questions that middle school students may ask in class, I also made corresponding preparations when designing CAI courseware. I narrowed down the scene of events that may be mentioned in the students' discussion and put it in a corner of the screen. When the students mentioned it in the discussion, I used the magnifying program to display it in full screen in time, which was clear and harmonious. In this way, the teaching materials before class are fully prepared, the operation is simple, and the pictures, words and music are well coordinated, which really improves the effectiveness of preparing lessons in art class teaching.

(2) The popularization of information technology also provides students with favorable conditions for previewing and collecting information before class. For example, in manual teaching, students search online for information about painting, paper-cutting, clay sculpture and animation according to the preview task I put forward before class. In this process, the students are greatly attracted by the interesting content of this class. When exchanging information in the classroom, students have a strong desire to express themselves, which in turn promotes the sublimation of the overall classroom atmosphere and lays a good foundation for the smooth development of bilateral activities and teaching between teachers and students!

Second, the clever use of information technology to optimize the classroom teaching process

The rapid development of modern information technology, especially the application of computers and multimedia, can collect, edit, store and display materials such as words, sounds, moving images, graphics and pictures, and organically combine, process and process them, thus optimizing the classroom teaching process, revealing the essence of some concepts that are difficult to explain in previous teaching, bringing educational technology into the information age and greatly enriching the content of education. teaching

(A) at the beginning of class, interesting. Stimulating interest is the primary link in classroom teaching. Carefully designing this link will make students have a strong desire for knowledge from the beginning of the new lesson, which is very important for students to learn new knowledge. Therefore, in the process of art teaching, teachers can skillfully use information technology according to the characteristics of teaching content and students' psychological characteristics, follow the principle of interest and pertinence, and according to the content of new courses and students' learning reality, so as to urge students to have a strong desire for exploration and knowledge, and thus enter the best learning state. For example, at the beginning of the teaching of "Forest Kingdom", I used CAI courseware and guessing game to "guess": the "hero" of this lesson was hidden under nine color blocks arranged neatly on the big screen, and the teacher clicked on the color blocks at will, and the parts of the objects below were revealed. Students make bold guesses through observation and answer first. When the teacher clicks on the largest color block in the middle, the fierce tiger roar and the complete head image of the tiger make the students suddenly realize. The introduction of information technology combined with game forms is very interesting and objective. The impact of the tiger shape and the tiger sound in the courseware gives students a double audio-visual shock, which not only exercises their observation and reaction ability, but also greatly stimulates their desire to continue exploring new knowledge. At this time, the teacher revealed the topic of this class (the writing of the topic is also processed by computer) and the content of the activity, which not only expressed the theme of this class, but also made people feel natural and fluent. In this way, the introduction of the new curriculum makes students have "doubts" and interest in learning, so the mood of exploring the mysteries of new knowledge arises spontaneously. With strong curiosity and strong interest in learning, they actively began to learn new courses, laying a good foundation for completing the teaching objectives and achieving the good teaching effect of "students who are interested at the beginning of class"!

(2) Inspiration and exploration. Enlightenment is a link to train students to think, find and ask questions diligently, and it is a personal activity that uses a variety of senses such as vision, hearing, touch, speaking, trying to do and trying to draw. The link of "induced exploration" is closely related to the link of "inspired thinking" and is the central link for students to explore new knowledge. Therefore, creating scenes to make students think and explore problems is the main link of classroom teaching. In this process, it is an indispensable teaching method to keep students happy in learning and really improve teaching efficiency.

1. In the past, to appreciate the rich pictures outside the textbooks, you needed to collect a lot from newspapers, books, slides and videos, and teachers needed a lot of oral explanations when giving lectures, which made students uninterested, let alone appreciate the pictures with scientific knowledge. However, after using computer and LCD projection teaching, the appreciation part of art class has been greatly improved and become interesting. For example, when I teach Butterfly Dancing, I let students appreciate and understand the basic growth process of butterflies in the form of questions and answers and CAI courseware display, so that art teaching and scientific knowledge can be closely combined naturally. The display of "special butterfly" pictures in courseware gives all students a novel visual enjoyment, thus subtly affecting their bold creation. The dancing butterfly in the following video made students fully feel the graceful butterfly, which greatly stimulated their desire for exploration and passion for creation, followed by the appreciation of a large number of beautiful and peculiar butterfly photos, which aroused children's love for butterflies and nature. The audience can not only get a glimpse of the whole work, but also zoom in on some parts for observation. Students are in the classroom, but they can break the boundaries of time, space and region, stroll along the painting corridor, fly in the imagination space, and aesthetic education is imperceptible.

2. There are countless applications of physical projection. Natural presentation and re-enlargement of pictures in textbooks; Teachers demonstrate skills such as painting and production; In the process of displaying students' works, physical projection can be used at any time to achieve good display effect. In addition, this super-large display of pure visual art on the big screen takes care of all the students in the classroom at the same time, not just some students in the front row can clearly watch all the displays, which fully embodies the teaching principle of education and teaching for all.

3. The application of computer painting provides convenient creative conditions for the teaching of design application courses with strong skills in primary school art courses. In the basic education of technology and design, teachers should do a lot of demonstrations and students should do a lot of training. Because the graphics of this kind of teaching content are very standardized and strict, and the coloring skills are very particular, it is very time-consuming and laborious to make model paintings or complete homework. However, it is very convenient to draw, color, edit and modify graphics in the computer, because the software provides a large number of drawing tools and editing commands for users to use. For example, the single pattern, two-way continuous pattern and four-way continuous pattern in traditional patterns are relatively easy to generate graphics in a computer. The principles and methods of a series of plane composition, such as midpoint, straight line and plane, as well as repeated composition and gradient composition, can all be displayed in the computer. As far as repeated composition is concerned, for example, in the course of Beautiful Lace, I first designed a simple pattern, changed the direction, size and color of the pattern according to the set bone lattice arrangement in the teaching process, and then animated it, so that students can easily complete repeated composition of the pattern. In this way, students have intuitive visual perception, and computer art design is flexible and flexible, with strong plasticity, and sometimes unexpected effects appear.

In addition, for primary school students with low modeling ability and creativity, computer design can make up for the lack of basic skills of hand drawing, strengthen the cultivation of creativity, imagination, appreciation and criticism, and infiltrate emotional education, which is very beneficial to students' quality education.

4. The key and difficult parts of art textbooks can also be edited and synthesized with the help of PowerPoint, Authorware and Flash. According to the different teaching contents, we can reproduce the situation, integrate teaching materials, teachers' speeches and students' thinking, and use a lot of intuitive and vivid perceptual materials to help students broaden their horizons and accumulate materials, so as to highlight key points, break through difficulties and complete teaching objectives. For example, in the teaching of Forest Kingdom, according to the knowledge points, key points and difficulties in this textbook, I made an animated scene with a computer: the forest of four seasons and the appreciation of a large number of animal pictures. Students are immersed in the infinite reverie and yearning for the forest, and their emotions are at their best. By adding beautiful language enlightenment and music touch, the key points of this class are solved, the difficulties are broken through, and students are actively influenced by beauty. Received the teaching effect that ordinary classroom can't achieve, highlighted the key points and broke through the difficulties.

5. Using the Internet to teach art can greatly shorten the time and cycle of knowledge and information dissemination, and at the same time, it has the characteristics of more vivid form, simpler method, wider scope and higher efficiency. This creates conditions for helping students understand, analyze and acquire new knowledge. In addition, because of students' freedom and selectivity in searching for information (text materials, picture materials, video materials, etc.). ), fully emphasize the principle that teaching should face all unified requirements, teach students in accordance with their aptitude and develop their personality, so that classroom teaching can achieve twice the result with half the effort.

Therefore, our art teaching can make full use of the network, obtain the latest art education resources, develop new teaching contents, explore new teaching methods, and carry out exchanges between students, schools, provinces and cities, and the works of foreign students and teachers' teaching achievements.

6. The recording function of tape recorder and pen and the image recording function of camera and video camera can help students identify, remember sounds, recall and record pictures, and apply them to the enlightening and inductive links in teaching, so that students can be inspired and inspired.

For example, when we explain the demonstration performance, we shoot it from different angles and then release it, which can solve the operation process that students can't see clearly and understand, and can also play it repeatedly to eliminate students' fear. Make students understand the creative process clearly, confidently and happily, and learn how to express and create beauty.

(3) Guidance and creation. The innovation link is a link that guides and encourages students to boldly apply and innovate the knowledge and skills learned in the above links, so that individuals or groups can complete a novel and unique work. In this process, we should give full play to students' imagination, creativity and practical ability to show their own personality. In this link, I use the related linked music suitable for creation in the courseware to set off the creative atmosphere, so that students can listen to music while creating and feel the wonderful enjoyment brought by the unique melody of music. Cultivate students' sentiment and enhance their creative passion. For example, the arts and crafts class plays children's songs or fast-paced music, so that they can find inspiration in light and happy music; Ink painting is accompanied by melodious classical music. In a deep musical atmosphere, we try our best to figure out the charm of pen and ink and create a beautiful ink painting. Reasonable and ingenious use of information technology means, give full play to the expertise of the media, give students a relaxed and happy learning environment, so that students at different levels can experience the joy of success.

(4) statement, introduction. Whether one's own creation can be recognized by teachers and classmates is extremely important for children. Using advanced physical projection, the works can be clearly displayed in front of the audience for everyone to appreciate and evaluate. "Introduction" is to inspire and guide students to speak freely and evaluate their own and classmates' works in simple language. Among them, treat every student well in guidance and evaluation, and adhere to the "four protections", that is, protecting personality, self-confidence, innovation and interest.

(5) Summary and extension. This is the last five minutes of the class, the summary of both students and teachers, and it is an indispensable link in a complete art class. In this process, we can choose to combine the materials that need to be summarized with PowerPoint to scroll out in the form of words, which is clear and easy for students to understand. In the extension of the class, we can let students talk about their experiences. In addition to talking about their feelings in class, we should also pay attention to guiding students to connect classroom and extracurricular activities and extend the knowledge they have learned to life. Here, we can once again make use of the powerful advantages of information technology to find out the relevant knowledge problems mentioned by students in the fastest and most convenient way from the Internet in time, so that all students can understand what they have learned and apply what they have learned, and cultivate the constancy of students' interest in learning art. In addition, I also played a science fantasy video in the teaching extension of Forest Kingdom, which caused the forest to be destroyed, the earth environment to be severely damaged, and human beings and animals to have nowhere to live until they died tragically.

This five-ring teaching method tries to make me find that students' interest in art has been greatly improved; The fluency, flexibility and originality of students' thinking are developed; Students' works present unprecedented diversity; Students' language expression ability has been improved; It has effectively changed students' learning style and become the initiative in learning. It is true that there is no strict boundary between the various links of the above teaching methods, and it is not static. There are many kinds of art classes, which should be analyzed in detail.

Third, some problems in information technology-assisted teaching

When we use information technology to assist teaching, we must pay attention to that information technology is only an auxiliary means of teaching, and its purpose can only be to make up for the shortcomings of traditional teaching methods, and it can only be a necessary technical assistance to play the leading role of teachers. In the application of its auxiliary teaching, we must pay attention to the following issues:

First, we can't "substitute the auxiliary for the main". In teaching activities, students are the main body, teachers should play a leading role, and information technology is only an auxiliary means to achieve better results. If we blindly rely on information technology and reproduce all the teaching links by multimedia means, then teachers will become slaves of information technology and only play the role of announcer and commentator, rather than the leading role that teachers should play. For example, the demonstration of an art teacher is sometimes irreplaceable. If you switch to multimedia, even if the performance effect is good, the teaching effect is still not as direct and unique as the teacher's personal demonstration.

Second, it is impossible to "use information technology means for the sake of using information technology means". Information technology can provide sound, light, electricity and other signal stimuli, which can effectively attract students' attention. However, if we blindly use all kinds of media regardless of the actual teaching needs and make the classroom information too much, it will lead to the overflow of invalid information and distract students' attention, which will not only not assist teaching, but also affect the realization of teaching objectives.

Third, we can't "replace the actual operation with simulated operation". Using information technology can easily simulate reality, and even simulate the effects that are difficult to achieve in reality. However, if you are keen on simulating the operation on the computer and ignore the actual operation of students, it is bound to be detrimental to the cultivation of students' practical ability.

Fourth, we can't "replace students' thinking with teachers' activities". In teaching activities, students' main role must be brought into play. The role of information technology-assisted teaching is to stimulate and mobilize students' thinking enthusiasm by using modern technology, inspire students' thinking, and cultivate students' ability to find, think and solve problems. Therefore, in the practice of applying information technology to teaching, we must be careful not to let audio-visual media occupy students' time of exploration, analysis, thinking and even hands-on, and we must take cultivating students' thinking ability as an important teaching goal.

Fifth, we can't "replace teacher-student dialogue with man-machine dialogue". Teaching activities are activities in which teachers and students participate together. In teaching, through the dialogue between teachers and students, the exchange and feedback of information and emotion, both sides can grasp the teaching process in the dynamic process, help teachers complete teaching tasks and achieve teaching goals. If we blindly rely on computers, only pay attention to man-machine dialogue, and ignore the information and emotional feedback between teachers and students, then teaching activities will be in a one-way information system, and students will feel a cold mechanical operation, lacking the classroom affinity and appeal they deserve.

In short, in the process of art teaching, as long as we skillfully use information technology and give full play to its role, we can optimize classroom teaching, break through teaching difficulties, solve teaching priorities, effectively improve teaching effects, enrich students' perceptual knowledge, broaden students' horizons, stimulate students' interest, cultivate students' innovative consciousness and spirit, and more importantly, promote the all-round development of students' quality, thus better promoting the rapid development of modern education and quality education.
