The difference between electronic whiteboard and multimedia teaching all-in-one machine （1）
In the field of modern teaching, the Multimedia Teaching All-In-One Machine is developed by the Electronic Whiteboard. In the initial classroom, there were only blackboards and chalk, and then projectors and Electronic Whiteboards slowly developed. Ordinary Electronic Whiteboards should be used with a projector, and the projection is affected by light, resulting in unclear images. Multimedia Teaching All-In-One Machine integrates Electronic Whiteboard software, computer, TV, host, monitor, and audio into one, with simple operation and clear picture. Let's take a look at the difference between an Electronic Whiteboard and a Multimedia Teaching All-In-One Machine.
1). Introduction to traditional Interactive Electronic Whiteboards
1. Ordinary Electronic Whiteboards should be used together with a projector, the projected image is not clear, and the projector bulb becomes dark due to prolonged use, and its service life is limited.
2. Projection requires a dark room environment. Students can clearly see the projected content but cannot see the teacher's expression clearly.
3. Different devices such as PC, projector, and various cables need to be connected.
4. It is difficult for students to concentrate, and classroom efficiency needs to be improved.
5. The front projection light is dazzling, hurting the teacher's eyes, and there are shadows on the screen
