Very interesting. Looks like a great display combining historical artifacts, story boards and animations. The US had a tradition of one-room country schoolhouses on the frontiers in the 1800s but also had some universities that were well established by then. The establishment on the East Coast was much different than the West.
Back in those days, these one room and combined classes were very common as students were few. The sad thing is, there still are some in the world today. It's far from ideal though.
