[comp.edu] HELP!, need references on Scenario machines and Training Wheels.

lagache@violet.berkeley.edu (Edouard Lagache) (04/30/88)

          Can anyone give me a pointer to papers on application
          software help systems known as "Scenario Machines" and
          "Training wheels"  I am looking for references on work that I
          believe was done at the IBM Thomas J. Watson research center
          by John M. Carroll, probably in the 1983-86 time frame.

          A Training wheels system is a software package that has been
          striped of is more dangerous commands and embellished with
          additional help (sort of like 'edit' versus 'ex' in Berkeley
          UNIX).

          A Scenario Machine is a curriculum on using the software that
          is latched on top of the software, so that the user can see a
          scenario of how the software can be used.

          Any help in locating such papers would be *greatly*
          appreciated!

          Thanks in advance!
