With the continuous attention and investment of primary and secondary education at all levels of the state, and the continuous development of computer, network, and multimedia technologies, the use of modern educational technology has been widely used in current primary and secondary school teaching. However, with the increasing number of multimedia classrooms, problems such as high maintenance costs and unobvious use benefits have also emerged. The problem.
1. Overall and forward-looking construction plan
For elementary and junior high schools, expensive multimedia equipment is generally not equipped at once, and most of them will be divided into two or even three or four batches to complete the construction. In addition to considering which grade needs to be installed first, it is also necessary to consider different batches of multimedia equipment. Not only the equipment model and specifications will change, but also the suppliers will change. At this time, it is necessary for managers to make reasonable arrangements based on actual conditions, safety and other factors.
In addition to the consideration of the installation order of multimedia equipment, in order to avoid repeated construction, it is best to install other lines such as the video line of the TV station and the network line of the campus network together, and leave an interface in the obvious place of the classroom to facilitate future work. Of.
Second, targeted training
Training is a critical part in the use of multimedia equipment. However, the current training is mainly organized by the municipal and district superior departments. The number of participants is small and the training content is difficult. Even if individual teachers have participated in the training, returning to the school can only exhaust the massive maintenance tasks. Therefore, targeted school-based training at different levels and levels of difficulty is particularly important.
For the problems of different difficulties in the daily use of class multimedia, we can solve them in three categories. The easiest way to turn on and off the power can be done by training the class instructors (students); the more difficult courseware is produced and used. Common line faults such as poor plug contact and system faults such as computer viruses can be carried out Relevant training; other professional faults, such as overheat protection, light bulb burst, excessive dust blocking the light path and vents, system problems, etc., can be resolved by full-time information teachers.
3. Scientific and standardized management system
In use, the equipment failure is mainly caused by the misoperation of the instructor. The teachers of the class do not have enough cognition of the multimedia equipment, and most of them think that the multimedia equipment only needs to be turned on and off simply, and does not operate according to the standard procedures. The main performance is that the power is turned off after the class without waiting for the warning light to go out, which will cause the projector lamp to dissipate heat, which will seriously cause the lamp to age or even be damaged in advance. This kind of irregular behavior not only brings unnecessary maintenance burden to multimedia managers, but also seriously affects the normal teaching activities of themselves and other teachers.
The standardized management system mainly stipulates the following points:
1. Standard operating procedures
Publish the standardized operation process in a conspicuous place in the classroom or multimedia equipment, and make teachers or students operate according to the process through appropriate rewards and punishments.
2. Regular hardware maintenance
Through regular cleaning and maintenance to solve problems such as clogged vents and lamp dust removal, improve the brightness of the projector and extend the service life.
3. Perfect data preservation
Through the preservation and reading of quality assurance books and user manuals, many difficult problems can be solved. At the same time, the fault elimination methods are classified and recorded, and experience is continuously accumulated, which improves the speed of troubleshooting and repair of similar faults and ensures the smooth progress of multimedia teaching.
4. Timely system upgrade
Multimedia devices connected to the network, the timely upgrade of anti-virus software and systems is particularly important. Of course, you can also install a recovery card to protect multimedia devices that are highly vulnerable to virus threats.
Fourth, establish a perfect resource library
At first glance, the establishment of a resource library seems to have nothing to do with hardware management. In fact, multimedia devices without resources can play the same role as a small blackboard. As a manager, you should use the FTP service or other resource website to store the materials used by teachers in classroom teaching, and classify and store the resources for students' self-study and extracurricular learning, and facilitate teachers and students to query and download.
V. Introduction of new methods and new concepts
With the continuous development of multimedia and network information technology, new software and hardware applications are constantly being developed. For example, through the network repair system, the staff responsible for the maintenance of the multimedia classroom can have a comprehensive and reasonable grasp of the operation of the multimedia equipment in the school in the office. Arrange maintenance time to improve work efficiency; if you use network control, you can remotely control all the equipment in the multimedia classroom, and you can open the class multimedia while sitting in the office.
All in all, multimedia-assisted teaching has become the mainstream teaching method in primary and middle school classrooms due to its intuitive, vivid and interactive features. As a manager, we should make a scientific and forward-looking plan, and at the same time establish a management system that is in line with the situation of the school, make multimedia management more scientific and reasonable, and provide a powerful guarantee for teachers to improve the teaching effect and the benefits of multimedia equipment.
