One thing I can see this being used for is fork lift driver training. You could put the person in the seat of the heavy and expensive equipment without actually risking anything. The user can play around with the controls and make mistakes without the fear of breaking something. That alone would be valuable.
on a side note, it also took my interest to new levels because the 3d animations revealed to me just how mechanical our body is, with a hierarchy of components very much like an integrated circuit.
so I can only imagine what it will be like to conduct labs or teach students using a 3d VR environment. It has a unique edge that not even the best teacher on earth can do-trick its users into believe they are not in lecture, but in a video game like world but with higher productivity.
It might also be great for teaching science, since VR can communicate scale much better than drawings.

At my high school somebody asked the calculus teacher why he was the calculus teacher and not another teacher. "We drew straws and I lost so I went to the training".
my mom was a teacher, and i clearly remember the required use of powerpoint to be a major detriment to her teaching. as another example, i was horrified recently during a volunteer opportunity at a local high school at the use of chromebooks in the classroom. it seemed like such a blind use that served no purpose other than to further seaparate the students and teachers from social interaction and communication.
i think something like dynamicland is the only technology that has promise to be used as an educational tool.
