Abstract
Authoring tools for intelligent tutoring systems are especially valuable
if they not only provide a rich set of options for the efficient
authoring of tutoring systems but also support controlled experiments
in which the added educational value of new tutor features is evaluated.
The cognitive tutor authoring tools (CTAT) provide both. Using CTAT,
real-world "example-tracing tutors" can be created without programming.
CTAT also provides various kinds of support for controlled experiments,
such as administration of different experimental treatments, logging,
and data analysis. We present two case studies in which example-tracing
tutors created with CTAT were used in classroom experiments. The
case studies illustrate a number of new features in CTAT: use of
Macromedia Flash MX 2004 for creating tutor interfaces, extensions
to the example-tracing engine that allow for more flexible tutors,
a mass production facility for more efficient template-based authoring,
and support for controlled experiments
