Architecture of an E-Learning System with Embedded Authoring Support
In this paper we introduce an architecture for an e-learing
system with an embedded authoring system. Based on the metaphor of a
construction kit, this approach offers a general solution for
specific content creation and publication. The learing resources are
IMS Content Packages with a special structure to separate
content and presentation. We call these packages Template Content
Objects (TCO) which contain a template coded in XML and additional
files for multimedia learning objects. They are similar to the SCORM
Sharable Content Objects (SCO) and can be simply translated to
them as well as combined to Content Aggregation Packages. These
aggregated packages represent higher structures like lessons,
chapters or complete courses. The developed authoring system
consits of different authoring tools that handle TCOs. Every task in
the process of learing object creation is done by experts which we
modeled with the help of roles. The architecture is result of the
math-kit project, a web based e-learining system that provides lecturers
and students with multimedia support for central topics in
undergraduate mathematics.
