The problem in the use of campus network (transparent) On November 20, 2004, I found a good article in the construction and use of our high school campus network on November 20, 2004, especially as a network management personnel, should look at this article. Maybe it will help our work. Although we are just a small part of our school, maybe we don't talk about the right to work, but we should understand what kind of work we are doing, we are in basic education In the implementation of the "School School" project, what kind of role is played in the implementation of our minimum quality. Let us let us read such an article I reprinted and make progress! (In this paper, I have compared the actual situation of our school, as long as it is a bold part of the black body, I hope that I hope to help you)

[Key words] campus network; network teaching; network classroom; use efficiency
Foreword
The application of campus network, online classroom is the starting point and home of the entire campus network. However, many educational metropolitan networks, campus network, did not play an efficiency and efficiency in education management and education teaching, and became an education department and school in school. Unbearable expensive decorations. It is undoubtedly the biggest failure of campus network construction. Under the premise of network performance, bandwidth and resources, how to effectively apply the network, improve the efficiency of the use of campus network and network classroom, worth thinking and discussing. This paper summrates recommendations from the following five aspects, hoping to get a major colleagues, and strive to give play to the campus network.
First, clearly build network guidance ideas - practical first
Common to such a so-called "campus network": I bought some very high-grade computers and very good network equipment, but the teacher only used the computer to typing and other simple applications; there are also some transmission analog signals closed-circuit monitoring system. Campus network can only transfer videos. These "campus network" investment is very huge, and the utilization is very low, very unfortunately. Therefore, how to build a campus network has become a key issue.
The construction of physical networks includes four aspects: structured cloth, network communication (selection of network devices), server selection, and terminal selection. The author believes that the overall planning step should be taken: On the other hand, some school bases are relatively poor, the teacher's awareness is insufficient, the use of computer networks or the application level is low. Even if some systems are installed, it is not possible to step by step. But step implementation must be carried out under the premise of overall planning, and if the overall planning is lacking, the system will fall into a very waste of mutual compatibility and pre-investment. Here is the order of the system implementation: First investigate user needs, determine the application system, then determine the system software, and finally select the hardware according to the needs of the above, rather than buying a bunch of devices. The current advancement, future scalability, and economic feasibility should be combined when designing a network plan. Current computer network technology has developed very quickly, and the equipment update is eliminated. It is recommended to use current mature advanced technology and equipment, which should have good expansion, which is compatible with future possible technologies. It is recommended that the school uses 100M fast Ethernet, but network devices should have an interface between 1000m and ATM modules. (Our school has such problems, the campus network is basically built, but also put into use, but the teachers use some basic courseware, or find some information on the Internet, expand knowledge, basically no campus Net came to network teaching, nor did it collectively prepared online, one is there is no such environment, but the teachers' own level is also limited, we are increasing the training of teachers, it seems that our mission is still very difficult, but I seem to make the teachers to improve your understanding is important, like the teacher in our school, since I haven't seen him after each teacher is equipped with PC, of course, this is just a few.) Second, clarify the campus Net use goals - application-based
Computer network wants to play its role, there must be an application system built on it. It is necessary to improve the efficiency of the campus network and should pay attention to the construction of the application system. Here is a very image of a metaphor: the network is like a road, and the application system is like a car, only the road is just road, but there is no car running, and the road cannot play its role. According to relevant surveys, most of the computer education fund investment in computer hardware environments, software investment is far lower than the input of computer hardware, and the capital investment of teachers training is minimal. Many schools do not hesitate to spend millions of online hardware facilities, tens of millions, but in various software resources (such as online teaching platform, school business management system, various multimedia teaching courseware, information database, etc.) Flower, causing the serious lack of software resources. This kind of importance of hardware investment, and despite software resource construction is also the cause of network resources that cannot be utilized. The appropriate application system should be selected according to the actual situation of the school. The application system has to be exchanged with the school to develop, and must meet the actual situation of the school. To explore the solution, you should first recognize the typical application of the campus network, and establish a rectification goal with this:
1. The campus network must be able to learn activities for the student, it is a learning tool. It is not only a communication tool between students and others, but also the provider of learning resources, and it is conducive to students to explore learning and collaborative learning. (In addition to class, our school students have no opportunities to use the computer as a means they know, it seems to achieve such a goal, we still need a lot of effort, the key is the support of the school leaders.)
2. The campus network must be able to serve the teacher's teaching and research activities, such as providing teaching resources, auxiliary teachers, and participating in classroom teaching activities and support teachers and then learning activities. (This school should be basically done, but I think that the school provides such hardware and software environments to teachers, the key is that the teachers have their own views of the network, let them feel the network from the heart. The huge role played in the teaching process, I think this should have enough pre-training to deepen the teacher's understanding, reform their thoughts.) 3. Campus network must be able to serve school education, such as auxiliary school Student status management, personnel management, financial management, etc. (In this regard, we have started to use, and prepare for some software resources, like software such as some special financial management systems and book management systems, because of the use of electronic management, it should be convenient, saving a lot of human and labor, And it will increase efficiency. However, the problem it brought is to pay attention to network security, which depends on professional hardware or software firewall to resist hackers to avoid information hidden dangers.)
4. The campus network must be able to communicate with the outside of the school, using it to obtain various information from the school, or to release various information outward. (Our practice is to build a campus website. Now our school's campus network has been built. Through the campus network students can continue to visit the home page of the school in the holidays, parents can also understand the school through the campus network. , Like enrollment, holiday, start, time, etc., and you can also leave on it, bring your own recommendations to us through the network, or you can write our principal to our principal and so on, etc., I think It is very good, and in the future time, we will fight for better.)
The construction of the system platform mainly includes: network operating system, desktop platform, database, firewall, etc. General school commonly used applications include: multimedia network classroom, multimedia electronic reading room, network multimedia courseware production system, campus information management system, video on demand, school homepage, etc. Such as a school application system includes: campus management information system, student management, faculty management, archive management, document management, principal inquiry, salary management, property management, party membership management, multimedia courseware production environment, multimedia material editing system, multimedia material management system , Multimedia courseware management system, multimedia courseware management system, multimedia courseware production system, online exam, teaching evaluation system, multimedia electronic reading room, multimedia network classroom, Chinese education VOD system, school homepage, etc.
Multi-angle improves the efficiency of the campus network. More applications involving teachers, students study, school management, students can borrow books or read the e-book magazine on the Internet, and visit various educational resources through the campus network and the mirror site of many learning websites established by the school. Teachers can use various multimedia teaching system aids, or electronic courseware system auxiliary preparations; schools can conduct daily school management through digital campus platforms, such as electronic courses, performance management, etc.
1. Establish a multi-function class: School classroom should be connected to the closed circuit television system, and then use a single microcomputer to connect with the campus network. There is a microcomputer with a large-size color TV in each classroom in the school. Set of simple economic demo systems. This is not only for students to use network resources; at the same time for teachers, it is used for speeches, academic reports, ordinary courseware demonstrations and computer teaching. It is best to be equipped with a multi-function projection system or a large-sized color TV system, with a computer-centric, including multimedia projector, video recorder, video display, power amplifier, large-screen and control system, etc. .
2. Strengthen the construction of computer network classroom: within the local area network connected to the computer classroom, the teaching content is released directly from the network. In some computer network classrooms, there are audio and video channels, and the contents of the teacher machine or student machine screen can be broadcast onto another machine through the channel and support the packet. That is, it is also known as multimedia electronic classrooms, such classrooms are mainly used for information technology courses, student exercises, and other courses. Students can flexibly in a variety of learning methods, such as individualization, learning and collaborative learning. (These schools already have and are using the process, the results are still very good.) 3. Establish a virtual library: Store a lot of books in digital forms in the resource server, or provide various multimedia information via the VIDEO server Resource. Students can easily query, retrieve and use the information through computer networks.
4. Establish an electronic preparation room: Provide teachers to provide courses with network resources and various tools for curriculum design and development. It consists of a collection compression system, an image processing system, an optical disc production system, a teacher prepared system, a server, and a multimedia computer.
5. Improve the school office network: through the integrated information management system, school management system, school teaching management and daily management, such as student status management, curriculum arrangement, personnel management, financial management, fixed asset management, etc. Information can be released online.
6. Other applications: such as campus card system, use campus network and smart card (IC card) technology to form a complete campus card system internally, through an IC card, can be used as a student ID, a card, borrowing book, phone card For the meal card, etc., so that the school fully implements electronic information management.
Third, improve the level of users - emphasize training
The teacher is the user of the campus network, the teacher's computer application level directly determines the use of campus network. Due to the neglect of software resource construction and teacher computer technology training, the built campus network equipment is idle, no one is used, and there is no resource available, and the computer is only used as a normal text processing tool. The campus network is simply a piece of furnish, and does not give full play to its own role. It is extremely efficient.
At present, the computer level of most teachers has reached a level above level, and computer-aided teaching can be carried out in discipline teaching, and even initially developed, but because network technology is high-tech, the network administrators of each department are often The deeper computer theory shows the limitations of knowledge, still lacking online professional technicians to build and maintain the network, so that the campus network is rough, low standard, and even guarantees its normal use. For example: The campus network is just a simple integration of the disciplines made of each department, lacks organic links, making the branch directory, visitors often have to enter the directory by the directory, the next connection is still a directory, and even more complex In the path. In addition, lack of network use training and management services for the majority of teachers and students, a large number of teachers, students have not changed their inherent work, learning methods to actively use the network, will not guarantee the successful application of the campus network, so that the campus network, Maintaining the normal operation of the campus network becomes an empty talk.
Training is a relatively high scalability. From the perspective, training can be divided into four levels: principal training, training of campus network administrators, training of young backbone teachers, training of all teachers. Since the network technology is high-tech, the person who has mastered the technology is far from satisfying social needs, so there is a lack of network professional technicians to maintain the network, causing campus network to ensure its normal use. Therefore, we should also pay attention to the training of network professional technicians. On the one hand, it is necessary to conduct computer application technologies, computer-aided education and Internet applications for computer application technology, computer-aided education and internet applications. The purpose is to explore the application development of campus network through their teaching scientific research activities to apply campus network; On the one hand, with the help of the primary and secondary school teachers, the majority of teachers participate in the popularity of the popularity of the popularity of the basic skills and the training of modern educational technology, the purpose is to let all teachers actively participate in the teaching applications of the campus network. For students, join information technology courses in the curriculum reform, and cultivate their application network auxiliary learning ability. Summarizing the experience of previous training, in addition to doing a good job, pay special attention to such a few points: training must pay attention to effectiveness, and cannot go through the field. The training program should be scientifically reasonable, pay attention to the teacher's feedback.
Fourth, create a network application atmosphere - conscious application
Interests and motives for application campus networks through reasonable mechanisms. The school can organize lectures and experience to communicate, let the teacher experience the wonderful, colorful network, causing a strong curiosity and interest in the network. Then, due to the potential, the engine. Motivation is a tendency that triggers and maintains activities, which is an internal power that promotes people, and is a need for some activity in motivation and guidelines. Motivation can be divided into two categories of external motives and internal motives. The school has established the mechanism of corresponding incentive mechanisms and reform management not only rewards teachers who apply campus network in teaching, but also requires networking of daily teaching, creating an atmosphere of a network application, thus establishing a teacher application campus network. External motivation; additional training through new educational thoughts and education theory, establishing teachers' new educational concepts, thus transforming external motives into internal motives, that is, teachers truly recognize the role of campus network to teaching reform and cultivate students, consciously Campus network applications is essential for teaching work.
Five, the management mechanism of campus network - assessment evaluation
Refining the useful network evaluation criteria, from teachers, students, and various departments management staff. 1. Teacher's perspective, mainly from the following aspects: Can I easily browse and query online resources, use these resources for teaching design and research; whether they can call online resources in the classroom teaching; The network is counseling and examining students' learning.
2. Do students can easily browse and query online resources, use these resources as "individual learning", whether you can learn and process information from the Internet.
3. Does the management personnel can be easily managed to facilitate education, administration, student, financial, assets and book materials, etc., whether or not information data exchange can be exchanged between management layers. The school should be equipped with enough computer as much as possible according to the situation, and through reasonable management mechanisms, teachers and students who require campus network have enough time and opportunities to apply the network. In addition, the campus network should have a remote access system for the school teachers and students, and the teachers and students will use the campus network in the family, school, or business trips, regardless of the school.
to sum up
