1. A good computer experimental classroom can not only realize computer teaching, but also realize voice teaching, CD-ROM sharing teaching, audio-visual teaching, Internet sharing teaching and other functions, which can be illustrated with pictures and texts, and blend with scenes; With the help of computer network, the teacher's screen image (courseware content) can be demonstrated to all (or selected) students, and the student machine image can be monitored, controlled, and broadcast to realize two-way classroom teaching between students and teachers, students and students through the network. Through the connection with the school network management center, it can achieve the purpose of transmitting multimedia information on the LAN and the Internet. The teacher's imagination can be brought into full play on the basis of a large number of relevant information provided by the system and his own teaching experience, so as to improve the teaching quality and efficiency.

2. Solve some disadvantages of traditional computer laboratory, such as high cost of hardware repair and maintenance, frequntly hardware replacement, and difficult maintenance. Free the computer room management teacher from the heavy equipment maintenance and devote more energy to teaching and management. Let the computer laboratory achieve the purpose of convenient management and easy maintenance.

3. The introduction of advanced desktop cloud technology and its application in computer teaching and teaching management can greatly save energy and reduce carbon emissions. It can not only reduce school teaching costs but also respond to the national call for energy conservation and emission reduction.

Based on the principles of cost saving, stable operation, convenient management and easy maintenance, and in view of the problems existing in the current school computer classroom (maintenance and management difficulties), we are preparing to establish a new cloud computer laboratory based on cloud desktop computing technology, which is currently more advanced in the country.

The cloud computing laboratory adopts the current extensive cloud computing terminal+server model, introduces the latest computer network technology into daily management, and effectively solves many problems existing in traditional computer applications, such as difficult network management, heavy maintenance workload, and high pressure on software and hardware upgrades. Desktop cloud technology is characterized by low operation and maintenance cost, progressiveness, ease of use, flexibility, reliability, security, etc.

The implementation of the desktop cloud computing project can not only inject new vitality into the development of school education informatization, but also bring about the update of educational technology and equipment. More importantly, it has brought about the update of concepts and nurtured the steady progress of school education towards leapfrog development.

Not only environmental protection, but also saving money

The comprehensive energy consumption of cloud classroom is nearly 90% less than that of PC
