2) Simulation Teaching Simulation teaching refers to the combination of multimedia technology and simulation technology, which simulates, simulates or reproduces something that does not exist or is difficult to experience in practice, so that learners can see their surroundings, enhance the teaching effect and improve the teaching level. For example, when a pilot first learns to fly a plane, it is impossible for every student to use an actual plane for flight training. Instead, through the simulation technology of multimedia computers, students can dive and spin when building a flight. Students can feel the real flight situation, such as overweight or weightlessness or rotation, as long as they bring data helmets, data gloves and data gloves and control the flight through the operation of data handles. With the in-depth study of multimedia technology and simulation technology, the theoretical method of realizing "virtual reality" has also developed greatly. People can be virtual and do not need expensive special hardware or auxiliary equipment (such as helmets, data gloves, high-resolution graphics workstations, etc.). In recent years, people began to use high-quality images taken by 360-degree panoramic photography technology to generate realistic virtual scenes. With the support of windows operating system or macintosh operating system, users can really feel the same virtual scene as in vr technology by using mouse and keyboard (without helmet and data gloves) on ordinary microcomputers. Moreover, this image representing the virtual environment can be compressed into a small space, occupying little memory. It can be seen that with the development of this technology, virtual environment teaching will be widely used in teaching. (3) Interactive Teaching Due to the development and integration of computer multimedia technology and network technology, students can learn independently through multimedia courseware or cooperate with network resources. These two learning methods have the same characteristics-both are two-way interactive learning methods. Multimedia and network technology can provide a comprehensive stimulus machine with pictures and texts, which is very conducive to the creation and maintenance of the situation, with friendly interface and intuitive image. They also organize and manage subject knowledge and various teaching information according to hypertext and hyperlink, and provide colorful human-computer interaction ways, so that students can get instant feedback and know their own learning results, so as to adjust their future learning methods or procedures. This kind of interactive learning is conducive to stimulating students' interest in learning and giving full play to their cognitive role. (4) Modern Distance Teaching The so-called modern distance teaching mainly refers to the open family teaching system based on computer network. With the emergence of network communication mode, multimedia courseware used in unit computers can be released to a vast network space, forming a network course. Through the opening of online courses, students can learn on demand regardless of age and fixed time, that is, choose different schools and different teachers according to their own needs and current level. Study at your own time, so communication based on computer network is a convenient and broader way of learning and communication, and it is also an important way to realize lifelong learning under the knowledge economy.
