At the EDTeam Canberra Summit, I went to a demonstration of google cardboard. I had previously seen VR applied to teaching with various VR apps on android and IOS. The benefit and drawback of cardboard is the immersive style of this approach. This is not something to do in a normal classroom. A gym or empty hall would be good to limit the risk of collisiions as students walk with the goggles in place. At the same time the immersive experience lifts the xperience to a new level. I could see teaching history by doing tours of historical sites. Geography would be covered by close walk throughs of terrain: seeing glaciers in 3D at realistic size. The biggest issue is matching the apps to the devices, the issue below that is providing goggles for all students.
