Informatization teaching in colleges and universities is the focus of teaching development in colleges and universities, and the traditional teaching environment is facing unprecedented changes. The status of teachers, students and teaching media will be repositioned, so as to build a teaching environment that can meet the needs of modern education. The construction of information-based teaching environment includes soft environment such as information resources and hard environment in campus network. Colleges and universities must strengthen the development and construction of information resources in the construction of soft and hard environment of information teaching, so that information teaching can really play its role. 1. Realization of information-based teaching environment in colleges and universities The construction of information-based education teaching environment in colleges and universities is a complex project, including the construction of soft and hard environments. We should plan and arrange the construction of hard environments such as campus broadcast teaching system, multimedia classroom and high-speed broadband campus network, and the construction of soft environments such as multimedia courseware library, digital library and multimedia material library. The hardware environment of teaching informatization in colleges and universities is the basis of realizing educational modernization and the condition and premise of developing modern education. In the teaching construction, we should give priority to online education and adopt the strategy of unified management, unified standards, unified planning and step-by-step implementation. The construction of hardware environment can promote the upgrade of software, and the construction of software environment in turn puts forward higher requirements for hardware environment. In the long run, the role of software environment is greater than that of hardware environment. Therefore, in order to give full play to the efficiency of hardware, we must vigorously develop the construction of software environment. (1) First, we need to build a high-speed broadband campus network. As we all know, the convenience, practicality, education and knowledge of computer network have been widely recognized by the society. At present, the breadth and depth of computer network application has become a symbol of the advanced level of science and technology, and it is particularly important for colleges and universities to build high-speed campus broadband networks. The network construction of colleges and universities should expand the coverage area, not only limited to teaching buildings, but also extended to libraries, dormitories, etc., and establish an all-round campus broadband network to make knowledge exchange more convenient. (2) Secondly, to build a fully functional network multimedia classroom, the implementation of information-based teaching needs a large number of multimedia teaching environments and virtual experiment environments, which are the equipment for students to directly obtain information-based teaching resources and the terminal for disseminating teaching resources. Students learn independently through multimedia machines, and at the same time connect their computers with teachers' computers. In this way, students can ask questions and communicate with teachers one-on-one. Students can learn freely and efficiently, and share resources at the same time, and finally build a large functional classroom. (3) Then, establish a campus broadcasting teaching system, including: campus broadcasting network and campus wireless FM foreign language broadcasting. Through radio teaching, students can also learn some knowledge when walking on campus, thus enriching their lives. In their spare time, students are more likely to accept the knowledge spread through modern media. Schools also need special storage devices to store multimedia teaching materials, software and so on. , mainly including various servers and storage devices. 3. Software environment construction (1) teaching system platform. It is a big stage for teachers and students to carry out teaching activities, including the management, development and application of the platform. Students can get rich learning materials, such as professional materials and background materials of various disciplines. Teachers can design courses, make courseware, guide students to learn, correct students' homework and so on. This platform is quite convenient, conforms to students' normal habits and supports students' personalized learning. At present, the teaching system platform is not perfect enough, so it is necessary to continuously improve and develop a more perfect teaching system platform according to the teaching needs. (2) Information standards. Information standardization in colleges and universities is a systematic project, which is restricted by various factors in the implementation process. Information standardization work should first investigate the information resources of major universities and find out the processing flow of all kinds of information. For those who can directly quote the established standards, they can directly quote; For those without standards, the basic principles of information system classification can be followed. At the same time, the standard system of information system should be forward-looking and scientific, and can remain relatively stable in a certain period of time. At the same time, the compatibility and openness of the information system structure ensure that it can adapt to different environments. (3) Management environment. A program can run perfectly, three points depend on technology and seven points depend on management. Whether the system can run normally depends on the standardization of management. In the information construction, it is very important to establish and improve the management standards of all kinds of information, just like driving on the road. There are revised rules before, and you must abide by them when driving. In the construction of various systems, there are mainly three types of norms: management norms, information service norms and technical norms. (4) Establish and improve the security system. After the establishment of information education environment in colleges and universities, anyone can access the official website published by the school through computing and terminal. Without a security barrier, it is easy to be invaded by viruses and hackers, and it is also easy to spread some bad information. Therefore, the establishment of security system is particularly important. Conclusion: The informatization construction in colleges and universities is a systematic project, including the construction of software environment and hardware environment. In the process of information teaching construction, the software and hardware environment should develop together and advance simultaneously, so that the information teaching in colleges and universities can move towards the established goals. With the continuous development of modern educational technology, China's education is expected to be in line with international standards in the future development process, in which information-based teaching plays an important role, so schools should speed up information.
