Abstract
Intelligent computer-assisted learning environments usually
involve complex strategies to help students learn a subject domain,
possibly with simulated or human companions. The design and
implementation of such systems rely much on the powerful features of
multimedia authoring systems. Traditional authoring systems can present
instructional content in dynamic ways with hypertext links, which
implement the instruction strategies (or learning strategies from the
student's perspective). However, they generally lack tools for organizing
the instructional content and for viewing and editing the organization.
Although some systems can use a network model to organize the content
materials, this approach embed explicit hyperlinks in the materials. We,
as well as some other researchers, argue that authoring tools should
organize instructional content and build dynamic learning strategies
independently. Based on this observation, we have designed and
implemented an authoring system whose pyramid architecture separates
the learning strategies from the content organization so that modifying one
would not affect the other. Moreover, the system‘s script language is
LISP, which is powerful for implementing intelligent models used in
learning systems. The system is called GETMAS---Goal Episode Tree
Multimedia Authoring System.
