"Engines of Education" by Roger Schank
This hyperbook is implemented as an "ASK system". You can read about my role in the design of the first ASK system, Ask Tom, in my ILS memoirs.
Briefly, 'Ask systems' were a hasty kludge designed to look impressive when implemented in HyperCard. They postulated eight sorts of possible conversational link between two distinct 'stories': background, results, context, examples, opportunities, warnings, alternates, and indicators.
We were trying to make a browsable video-bank out of several hours of video interviews with an Arthur Andersen accounting consultant. The idea was that after watching a clip, the user would scan these eight categories, each of which offered a handful of possible next clips to view.
The last I heard, the resulting demo had never been tested in any way. But the Department of Defense had been finessed out of several million dollars (I think) for a huge ASK system about one aspect of the Gulf War, a boondoggle the DoD must be regretting (as much as they ever regret wasting vast amounts of the taxpayers' money).
"Engines of Education" shows that Roger and his 'yes'-team have deluded themselves so absolutely that they now think this is a general approach to hypertext-- resulting in a conventional book that's been broken into paragraphs, each paragraph followed by a barrage of ASK- links... in case you're getting restive with the natural direction of the argument!
I defy them to publish their html logs for this site! Only a cringeing lackey could ever be patient enough to read it in this format in its normal sequence, much less reading all dozen questions after each paragraph, and so getting jolted repeatedly into hypertextspace...
