VR in the classroom

Every day, VR is becoming a more viable option for the classroom.  Companies like ClassVR now provide immersive experiences aligned with school curriculums, with preplanned lessons for a wide range of subjects.  Right now, Google offers its Google Cardboard, and a field trip simulation program called Expeditions, to schools for free.  Any student can now take a field trip anywhere in the entire world, regardless of cost or time.  Just like the internet and computers revolutionized teaching, VR will revolutionize it again.
