Comparing with the existing technology, by means of the above structure and the method, there are the advantages as follows: 1. the computer containing several utility software, which is convenient to use and teaching as well as the class work, is assembled into a multimedia playing machine to connect directly; 2. the multimedia teaching blackboard installed permanently in a classroom ensures the courseware of a lesson is mounted to the blackboard to operate through the network, an optical disc and a U disc; it is capable of real time introducing the network resource for on-the-spot teaching through external network access; it is capable of keeping the schoolwork after a lesson and the lesson contents in the blackboard, such that students may copy them to bring home or send them to their household computers through the network.

Description

technical field [0001] The invention relates to teaching equipment, in particular to a multimedia teaching blackboard and a teaching method. Background technique [0002] With the advancement of science and technology and the development of information technology, the traditional teaching mode is undergoing major changes. It is a consensus that the conventional single handwritten blackboard as a teaching tool cannot meet the needs of multimedia teaching at all. With the development of computer technology, projectors and other technologies in the domestic and foreign educational circles in recent decades, many explorations have been made in the application of classroom teaching display. At present, there are two commonly used methods for multimedia blackboards: [0003] One is a projector plus a computer.

Problems solved by technology

Disadvantages of this kind of device: 1. There is a certain distance from the projector to the screen, and the brightness and true color of the projection will be lost in the air, and the high-brightness projection bulb is too heavy and easily damaged. The price of the bulb Expensive, and it is unaffordable to change schools in a short period of time

2. The use of this device requires a large space, and the space in general classrooms is not enough.

Sometimes, the teacher blocks the projection

3. The device is scattered and needs to be kept manually

Its disadvantages: 1. Rear projection technology applies the principle of reflection projection

The thickness is too large, and it cannot be placed in ordinary classrooms

[0005] Due to the above reasons, multimedia teaching blackboards are currently used in some special classrooms, kept by special personnel, and not used in general classrooms.
