"I was surprised to find that the ducks were right in front of me! It was an exciting experience (经历)." Taylor said after taking off the purple headset and finding herself still in the classroom. Many students around the world are taking VR "trips" like Taylor. But what change does it cause in learning?
Taking children to visit different places is a good way to teach them about the world. But what can children do if they forget it after the trip? VR lets children go back at any time.
It's difficult to talk about something if you didn't see it with your own eyes in the past. If you didn't see the ocean, with VR, now you can have a look at it for yourself.
VR can also help students in science classes at school. "Too often at school, when you do experiments (实验), you put different kinds of chemicals together and then get the result. And if you aren't successful, you need to do it again, " a high school teacher said. "But we don't have enough chemicals. With VR, I just need to do it again on the computer. I don't have to use chemicals."
VR is useful, but that's not to say we don't need real-world experiences. The real world is what we really need to learn about.
