Not only can VC be used for field trips, but it allows rural communities to share teachers with specalities. If School A has a great physics teacher, they "share" that teacher with School B through VC. Now students in even the most remote areas can access resources that will allow them to take the steps forward to follow their passion.
I think that this would be a great resource to use to interact with different classrooms around the world. It would allow our students in their safe, warm classrooms a glimpse into what other students have to endure to get an education. This would be a very good lesson for our children. It would give our students a better picture of the world and a personal insight into what other children their age are facing.
I hope that I will be ale to implement this in my classroom someday.
