With the rapid development of computer technology, human society is entering the information age, and information technology itself has a far-reaching impact on the reform of education, which has become the core of educational modernization and the key to success. In order to fundamentally optimize the educational management and teaching process, all countries are improving the level of educational computerization, which has become a worldwide educational trend and reform trend.
With the maturity and popularization of computer technology, its application in education and teaching is becoming more and more common. In China, due to the economic development, its application is not widely enough at present. But its advantages are gradually recognized and developed rapidly. The application of computer in teaching represents the direction, trend and future of educational technology, and affects many aspects such as school education, distance education and future family education. In school education, the application of computer technology will have a far-reaching impact on educational means, methods, adaptability and creativity of students.
Second, the advantages of computer-aided teaching
Computer multimedia technology has become a hot topic that people are talking about at present. Its rapid development, rapid adjustment, deep penetration and wide popularization are all unexpected. In the fields of TV news, newspapers and magazines, advertising media, public service, information consultation, film and television entertainment, culture and education, industrial monitoring, medical diagnosis, national defense and military, commercial shopping guide, post and telecommunications, etc., its successful application is everywhere, and its relationship with people's activities is getting closer and closer.
People who come into contact with multimedia software for the first time will be deeply attracted by the vivid, vivid, audio and colorful multimedia performance. In fact, it is a technology that combines computer, graphics, image processing, film and television art, music art, education, psychology, artificial intelligence, informatics, electronic technology and many other disciplines and technologies. It integrates characters, graphics, images, sounds, video images, two-dimensional and three-dimensional animations and so on.
On the surface, computer multimedia technology is a technology that integrates words, images, sounds, videos and animations. In fact, its core and key is information digitization, the key to computer information storage and the essence of computer multimedia technology. Talking about computer multimedia technology without it is like a castle in the air.
Traditional text teaching materials, audio teaching materials and video teaching materials are all linear and orderly in information organization structure. However, people's memory is a network structure, and the linear structure limits people's free association ability. Computer multimedia technology is nonlinear, which can give full play to individual personality, speed up knowledge acquisition and improve knowledge acquisition ability.
Computer multimedia technology has been vigorously promoted and applied in teaching, and its advantages are reflected in the following aspects:
1, increasing the amount of information. Teachers can even use a small mouse to avoid exchanging tape recorders, video recorders, slide projectors, physical projectors, wall charts and so on many times, saving valuable time and greatly improving the amount of information.
2. Friendly interface, simple operation and convenient menu indication. When designing courseware, teachers can pre-design complex operating procedures on the panel, so that operators can choose their own learning progress and learning rhythm.
3, resources, information management image, convenience, suburbs, improve the management level.
4. It can better highlight teaching key points and break through teaching difficulties, simplify and visualize abstract and abstruse information knowledge by using 2D and 3D animation technology and video technology, and shorten the distance between objective objects and students.
5. Courseware is easy to carry and can be preserved for a long time. Courseware can be burned into a CD, and it will never wear out.
6. Computer-aided teaching can better stimulate students' interest, concentrate their attention and cultivate their spirit of exploration and research.
7. Interactivity is the most prominent feature of computer multimedia technology, which enables real-time exchange of information transmission and reception, unlike TV and radio, where people can only passively receive program content.
Third, the process of making CAI courseware
1, the purpose of determining the topic is to clarify the specific tasks and requirements.
2, courseware according to the requirements of the syllabus, first clear teaching objectives, requirements, and the focus and difficulty of teaching materials.
3. Writing a script is the first step to organize information, such as planning picture layout, graphic proportion, color tone, music rhythm, display mode and interaction mode.
4. Multimedia information materials include words, graphics, images, animations, audio and video.
5. According to the pre-written creative script and the existing creative tools, integrate multimedia information.
6. After the courseware is made, it must be thoroughly checked, so as to correct mistakes, fix loopholes and sometimes optimize.
7, explain the instructions, etc.
Fourth, the creation tools of computer-aided teaching courseware
1, audio processing tool refers to the tool software used to record, edit and play sound or music media. Common audio tools include WAVESTUDIO, SOUNDEDIT, CAKEWALK, MIDISOFT and so on.
2. Graphics and image editing is the basic processing technology of multimedia, and the commonly used tools and software are COREDRAW, PHOTOSHOP, ACDSEE32, etc.
3. Animation can be divided into two-dimensional animation and three-dimensional animation. Two-dimensional animation can realize some simple modeling, bit movement, color change and so on. Commonly used tool software is ANIMATOR STUDIO, etc. Three-dimensional animation can realize three-dimensional modeling and simulate various objects with three-dimensional realism. Commonly used tools and software are: 3DSTUDIO MAX, etc.
4. Video information should be collected from video sources such as video recorders or televisions through video acquisition cards, and then input into video editing software for editing or processing. Commonly used video editing software includes PREMIERE, Super Jieba 5.5, ANIMATOR STUDIO, etc.
5. Tool software based on page or card includes POWERPOINT, TOOLBOOK, etc. Icon-based tool software includes: AUTHORWARE, Founder Aosi, etc. Based on programming languages: VISUAL BASIC, VISUAL c++, etc.
Five, some suggestions in the application of computer-aided teaching.
1, "computer-aided instruction" belongs to the category of modern education, so it needs the guidance of modern educational thoughts and theories. If you use the original set, even if the equipment is advanced and the teachers are sufficient, it can't be regarded as computer-aided teaching. In traditional teaching, teachers are the center, learning is to let students understand and master what teachers teach, and the purpose of media application is naturally to promote "teaching". Modern educational theory emphasizes student-centered, and learning is the process of acquiring knowledge. It emphasizes that knowledge is not taught by teachers, but a process that learners realize with the help of others in certain situations, that is, through interpersonal cooperation, discussion and other activities. Multimedia computer can well create situations, human-computer interaction and teachers' participation in organization, so that students can develop their existing cognitive structure according to existing problems. Therefore, teachers must break through the shackles of traditional ideas in teaching and focus on how students learn to make an essay, making lesson plans first and then writing.
2. Computer-assisted instruction is inseparable from computers. Therefore, it has become the most urgent problem to improve the computer awareness and application level of teachers in various disciplines. Computers should be integrated into teaching like chalk and textbooks we use in class.
3. Computer-aided teaching can't replace students' main role in teaching. If it is not used properly, it will reduce students' chances of using what they have learned to solve practical problems and have a bad influence on new learning.
Development prospect of intransitive verb CAI courseware
1, CAI courseware should be intelligent. According to the information provided by students' cognitive model, through the search and selection of intelligent system, the contents and strategies suitable for personalized teaching are dynamically generated; Through the intelligent diagnosis mechanism, students' learning level can be judged, the reasons for students' mistakes can be analyzed, and at the same time, suggestions on haircuts and next learning content can be put forward to students. By publishing the statistical data of all students' mistakes, the intelligent diagnosis mechanism will provide teachers with suggestions on teaching priorities, methods, testing priorities and questions.
2. Computer-aided teaching courseware should be developed to network. Its advantages are that it is not limited by geographical area, enjoys convenient resources and is more convenient to update and maintain teaching content.
In a word, the application of computer multimedia technology in teaching has become the general trend, and there is a huge potential demand. However, China's investment in this field is far from enough, and it is urgent to organize and guide the national authorities to change the phenomenon of attaching importance to hardware and neglecting software, so that computer-aided teaching can develop by leaps and bounds. This is not only the need of current quality education, but also a new economic growth point. May the application of computer-aided instruction develop rapidly in China.
