Today, our teaching protocol and learning is becoming more modern. In there, a very familiar piece of furniture is the projector that has been shown at the school hours. The projector is a use for showing teacher's lecture. Before that, according to traditional teaching, teacher used a white chalk board to teach student. Teacher is a lecture, and student who has to listen, understand, and follow what he says. The massive weakness of this method is waste of time. Besides, it's boring, leading to students, graduating slowly. After applying the teaching method on the projector, the teacher can transmit the knowledge faster, easier by preparing a lecture on the computer and presenting the student on the lecture that becomes interesting, Much more attracted by the software that supports the image, sounds. Teachers can use video, audio file instead of using words, or lose a lot of time for television preparations to watch video. In conclusion, using this facility in class is very useful for both teachers and students.

Projector had not been used in the classroom for study before 20 years ago. This facility makes the lessons more interesting, especially in natural science subjects including Physics, geography , chemistry,…, the scientific events are illustrated through videos, pictures, and sounds. Students are usually amazed at how things happen on the screen, and they understand clearly about the lessons. This huge screen helps children to focus more on the lessons and not feel boring as the traditional teaching method. Before this device is used, teachers meet difficult explaining and conveying the natural events to students. They must utilize pictures or draw on the board by chalks, which took time but not effective. In my opinion, using projector is a great change, saves time in teaching and keep children engaged. It also provides more information in an effective and detailed way. Besides, this change will be continued thanks to the development of technology and Internet
