In the 21st century classroom, modern technology has made our learning experience more interesting. Also, it’s more interactive(互动的).
Now three kinds of tools in the 21st century classroom---a whiteboard, a computer screen and some audio tools(音频工具) are available. They have made a big difference in how students learn. An interactive whiteboard allows the teacher to show pictures and provide sound as well. A large computer screen has colorful pictures and sound in it. So lots of students’ attention is attracted by what they see and hear. Different kinds of audio tools, such as earphones and microphone, also help to make sure that everyone can hear the teacher. In the past, if a child missed some of what the teacher said, the child may have been too nervous to ask the teacher to repeat it. Now the students are not likely to miss what the teacher says with these audio tools.
The 21st century classroom is able to teach students more than one thing. Just imagine an English lesson is given in a modern classroom like this. How would it be different from a classroom in the past? The answer is simple. The students would learn about not only the subject itself but also how to use the modern machines.
The 21st century classroom can make teaching and learning easier. Now everyone is able to express their opinions or answer questions without having to speak loud. Since everyone can do it, the teacher can easily see who needs more help in other ways.
It’s clear that the 21st century classroom is really making a great difference.
