The negative effects can't be ignored. It is true that we can find anything we need through the computer, but we rely too much on high technology, how can we talk about further development? Media is an extension of human senses, but if we rely too much on technical means, it may also limit the development of the potential ability of some of our organs. Faced with a large number of colorful multimedia information times, teachers feel at a loss. They just browse the information resources, and have no real knowledge meaning. Inappropriate visual information may also inhibit teachers' imagination and deep thinking. Using the predetermined ideas and links of multimedia network information to carry out man-machine dialogue loses the space for independent thinking, and teachers' dependence on multimedia tools and technologies reduces the deepening of their own hands-on practice, independent thinking and research. If you encounter problems, you will ask for help online, which is high-tech, but without the network, you will be at a loss. From the perspective of development, this is very unfavorable to teachers' advanced cognitive ability and further development. Network broadens teachers' horizons and knowledge, and at the same time creates conditions for teachers' laziness and opportunism. The advanced technology and tangible technology in information are the support of educational technology, which has opened up a broad space and prospect for our education and teaching work. Technology and information are the products of advanced science. Failure to apply advanced technology and information well is the sorrow of education, and failure to strictly manage it is the dereliction of duty of the organization. The network serves us. Advanced science and technology can't be used completely, but should be used critically. Teachers should actively face the challenges brought by the information age, not only to improve their own information technology level, information teaching level and the ability to effectively apply educational technology, but also to strengthen the development of their own lives to adapt to the characteristics of innovation and development of the times.
