Imagine a school where students are taught by the best teachers in every subject, regardless of locations. Imagine a school where children can go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual reality（VR）.
Last month, Optima Academy Online（OAO）was launched in Florida and started to deliver courses for elementary, middle and high schools and 170 full-time students from all over the state signed up. They used VR headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins.
It is worth watching how such educational experiments develop. Used properly, the VR technology can help students to access learning resources and be connected with fellow students and teachers all over the world. But if employed poorly, it will have the opposite effect and turn a digital inequality into an educational one.
There is growing evidence to suggest that it is happening. In Mexico, according to a survey, only 24% of 15-year-old students in poor schools have access to home computers for schoolwork compared with 87% in rich ones. As reported in another study, some students in northern England have been forced to travel around on the Greater Manchester train network or camp out around McDonald's to access free WiFi because they cannot do their schoolwork at home.
"VR technologies will be widely used in education. The only questions are: for what purpose and at what speed?" says Beeban Kidron, a member of the UK's Digital Futures Commission. "The trouble is that they are too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a means to enrich learning. "
The inescapable truth is that there is nothing that can replace teachers educating students in safe schools—ideally, with access to ' well-designed technological platforms. Leaving children in their bedrooms with just VR headsets and no physical social interaction with other kids will fill-many of them—and their parents—with horror.
