Intelligent course management and training applications for students
design eLearning courses as storyboard graphs whose nodes are
elementary training units and whose edges encode dependencies between
them. A well-designed storyboard is then able to adapt the course to learner
by observing the history of the learning path and propose suitable course
elements to the student. However, setting up a storyboard and testing it
for correctness and completeness is a tedious task that can be well taken
over by the computer, too. Since storyboards are mathematically described
as graphs, known algorithms on graphs are readily deployed here and help
authors to setup consistent courses.
In this article, we introduce our course management ``Marvin'', describe
its properties in an eLearning framework designed to run interactive
experiments, so called ``Virtual Labs'', and introduce the structure of
its courses. We then define the terms correctness and
completeness of a course within the system and describe algorithms
that help authors to test for these properties.\\
