Dennis Jerz, professor at Seton Hill University presented a paper on the history of Adventure, which I believe is acknowledged as the first text-based computer adventure game.
I found many concrete suggestions in Jerz's presentation for those of us looking to develop software to teach expert bodies of knowledge.

Old fogey's? Geeze I must be "really" old. I understand the concept. I have found that to peak a child's interest you first have to make what they're doing fun. If they're enjoying themselves, then they don't recognize they are also learning. Brilliant article D Jerz.
