Today, studying is more modern and easier. Some modern facilities are used for studying such as computers, projectors, etc. One of them is projector. The projectors are used for helping the students imagine and understand better. But in the past, the students didn't have projectors. So they imagined more difficult about the processes were described in the books. I think the change has a big meaning. It helps the students study better.

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.

20 years ago, laptops were a distant dream for young people. They made drafts by hand with limited resources, but today we just need to tap to get hundreds, thousands of ideas awake. Computers have become indispensable devices today.

dịch 20 năm trước, máy tính sách tay là một giấc mơ xa vời của giới trẻ, họ làm các bài dự thảo bằng tay với nguồn tài liệu ít ỏi, còn ngày tay chúng ta chỉ cần gõ nhẹ là có hàng trăm, hàng nghìn kiến thức. máy tính như trở thành thiết bị không thể thiếu trong thời nay.
