IMHO, what matters most is not if the VR actually helps learning, but that a company such Facebook is putting a spotlight on Education. Zuckerberg could have mentioned a hundred different things where VR would be applicable.
The press release [1] from Oculus also mentions Education:
Mark and his team share our vision for virtual reality’s
potential to transform the way we learn, share, play, and
communicate
That was and still is the slogan of my previous employer.

I'd love to see this really take shape, I worked on the virtual education problem for a long time, and it badly needs an investment of money. If facebook invests in virtual education, I will be very pleased.
