A visual approach to procedural tutor specification

TANDEM (Task and Domain Environment Model) is a package for aiding the design of procedural tutors. Using this system, domain experts and teachers (the authors) can cooperate to produce an accurate model of a device or procedure and also incorporate appropriate feedback for the potential users of the simulation. This paper describes the interface to TANDEM and demonstrates how graphical representation of domains and tasks aids the authors in the production of their target system.
