To lower the cost and difficulty
of creating scenario-based intelligent tutoring systems for technical
training, Stottler Henke developed the Task Tutor Toolkit™ (T3), a
generic tutoring system shell and scenario authoring tool. This system enables the
instructor to create procedure templates that specify the range of actions
that are "correct" within each scenario and the knowledge and skills that
are demonstrated when the student carries out each sequence of actions.
The instructor creates these templates without programming, using a graphical
user interface to demonstrate, generalize, and annotate sequences of actions
to be recognized by the tutoring system.
At the end of each scenario,
the tutor displays the principles correctly or incorrectly demonstrated
by the student, along with explanations and background information. The
annotated procedure templates also enable the system to provide hints when the
student asks "What do I do now?" and "Why do I do that?" The Task Tutor Toolkit was designed
to be modular so that it can be interfaced with a wide range of training
simulators and support a variety of training domains.
Stottler Henke and NASA used
the Task Tutor Toolkit to create the Remote Payload Operations Tutor (RPOT), a tutoring system
that lets scientists who are new to space mission operations learn to monitor
and control their experiments aboard the International Space Station according
to payload regulations, guidelines, and procedures.
